Aim: To explore how overcrowding affects children's health, environment and schooling. Methods: A qualitative study was conducted with individual interviews among 20 participants with occupational experience from overcrowded Stockholm areas but diverse in professions, locations and employers. The interviews were recorded, transcribed and analysed with Systematic Text Condensation. Results: Almost all participants expressed that overcrowding has a negative impact on children's health, environment and schooling – based on perceptions of precarious and different living conditions for children in overcrowded areas, for example, substandard homes, vulnerability, stress, exclusion, limited resources, lack of learning opportunities, gender differences, confinement, shame, insecurity, conflicts, risk of criminality, and bodily impact, both physical and psychological. Conclusions: Our qualitative evidence suggest that overcrowding has a negative impact on children's health, environment and schooling. [ABSTRACT FROM AUTHOR]

Purpose: To explore actions taken by health care professionals during a procedure with a child with autism spectrum disorder Design and Method: Critical incident technique was used, which is a technique with a qualitative descriptive retrospective design, to capture situations experienced by health care professionals during a procedure in an anaesthesia or radiology department. Health care professionals from anaesthesia and radiology departments (n = 20) were interviewed about situations affecting the procedure. Results: The findings revealed a broad range of actions (n = 205) taken by the health care professionals during a procedure with a child with autism spectrum disorder. The analysis resulted in two main areas: Finding a way to facilitate a procedure in a high technology environment and Creating a trustful relationship with a child with autism spectrum disorder. The most common action in the first area, was to adjust routines. In the second area the most common action was to take one step at a time and not force or rush the child during the procedure. Practice Implications: The health care professionals used a broad range of different actions to facilitate a procedure in the high technology environment for a child with ASD, which indicates the need for a flexible approach. The actions taken included both adjustments to the environment and enhancing interactions with the child. [ABSTRACT FROM AUTHOR]

Background Diagnostic testing is essential for disease surveillance and test–trace–isolate efforts. We aimed to investigate if residential area sociodemographic characteristics and test accessibility were associated with Coronavirus Disease 2019 (COVID-19) testing rates. Methods We included 426 224 patient-initiated COVID-19 polymerase chain reaction tests from Uppsala County in Sweden from 24 June 2020 to 9 February 2022. Using Poisson regression analyses, we investigated if postal code area Care Need Index (CNI; median 1.0, IQR 0.8–1.4), a composite measure of sociodemographic factors used in Sweden to allocate primary healthcare resources, was associated with COVID-19 daily testing rates after adjustments for community transmission. We assessed if the distance to testing station influenced testing, and performed a difference-in-difference-analysis of a new testing station targeting a disadvantaged neighbourhood. Results We observed that CNI, i.e. primary healthcare need, was negatively associated with COVID-19 testing rates in inhabitants 5–69 years. More pronounced differences were noted across younger age groups and in Uppsala City, with test rate ratios in children (5–14 years) ranging from 0.56 (95% CI 0.47–0.67) to 0.87 (95% CI 0.80–0.93) across three pandemic waves. Longer distance to the nearest testing station was linked to lower testing rates, e.g. every additional 10 km was associated with a 10–18% decrease in inhabitants 15–29 years in Uppsala County. The opening of the targeted testing station was associated with increased testing, including twice as high testing rates in individuals aged 70–105, supporting an intervention effect. Conclusions Ensuring accessible testing across all residential areas constitutes a promising tool to decrease inequalities in testing. [ABSTRACT FROM AUTHOR]

Background Well-established associations exist between the risk of small for gestational age (SGA) and unidimensional sociodemographic factors. We investigated social inequalities in SGA risk and adopted an intersectional approach that simultaneously considers different social categories. By doing so, we could assess heterogeneities in SGA risk within unidimensional sociodemographic categories. Methods We included all live 679 694 singleton births in Sweden between 2010 and 2016. The outcome was SGA, and the exposures were age, maternal educational level, dichotomous migration status and civil status. Thirty-six possible combinations of these factors constituted the exposure in an intersectional model. We present odds ratios (ORs) with 95% confidence intervals (95% CIs) and the area under the receiver operating characteristic curve (AUC)—a measurement of discriminatory accuracy (i.e. the ability to discriminate the babies born SGA from those who are not). Results Women with low education and women born outside Sweden had ORs of 1.46 (95% CI 1.38–1.54) and 1.50 (95% CI 1.43–1.56) in unidimensional analyses, respectively. Among women aged under 25 with low education who were born outside Sweden and unmarried, the highest OR was 3.06 (2.59–3.63). The discriminatory accuracy was low for both the unidimensional model that included all sociodemographic factors (AUC 0. 563) and the intersectional model (AUC 0.571). Conclusions The intersectional approach revealed a complex sociodemographic pattern of SGA risk. Sociodemographic factors have a low accuracy in identifying SGA at the individual level, even when quantifying their multi-dimensional intersections. This cautions against interventions targeted to individuals belonging to socially defined groups to reduce social inequalities in SGA risk. [ABSTRACT FROM AUTHOR]

Background: Compliance with a study protocol is central to meeting its research goals. In longitudinal research studies, data loss due to missed visits limit statistical power and introduce bias. The Environmental Determinants of Diabetes in the Young (TEDDY) study is a longitudinal multinational (US, Finland, Germany, and Sweden) investigation of children at risk for type 1 diabetes (T1D) that seeks to identify the environmental triggers of islet autoimmunity and T1D. The purpose of the current study was to identify sociodemographic variables and maternal characteristics assessed in the first year of TEDDY that were associated with study visit compliance in the subsequent 3 years. Methods: Sociodemographic variables, maternal life-style behaviors, post-partum depression, maternal reactions to the child's T1D risk, and study-related variables were collected at child-age 6 months and 15 months. Multiple linear regression was used to examine the association of these variables to study visit compliance in the subsequent 3 years. Results: Study visit compliance was highest in Sweden (p > 0.001), in children who were their mother's first child (p > 0.001), and whose mothers were older (p > 0.001) and more satisfied with the TEDDY study (p > 0.001). Father participation was also associated with better study visit compliance (p > 0.001). In contrast, children whose mothers smoked (p > 0.001), suffered from post-partum depression (p = 0.034), and were more anxious about their child's T1D risk (p = 0.002), completed fewer visits. Father's study satisfaction was also associated with study visit compliance (p = 0.029); however, it was not significant in models that included maternal study satisfaction. Conclusions: Sociodemographic variables, maternal characteristics—including study satisfaction—and fathers' participation in the first year of a longitudinal study were associated with subsequent study visit compliance in a sample of children genetically at-risk for T1D followed for 4 years. This information can inform future strategies designed to improve study visit compliance in longitudinal pediatric studies. Trial registration: NCT00279318, 06/09/2004. [ABSTRACT FROM AUTHOR]

The study purpose was to, with the help of ICF and the CPS model, describe and explain patterns of co-occurring problems with participation in everyday life activities, body functioning and environment for children who completed brain tumor treatment. Hospital, habilitation and school records for nine children (5–11 yrs.) diagnosed with brain tumor, were retrospectively reviewed for everyday problems after treatment completion. These problems were linked to ICF codes. Median code distribution within ICF constructs participation, body function, body structure, activity, and environment were calculated to generate typical (close to median) and atypical (distant from median) patterns of problems on individual and group levels. Two children were in-depth analyzed with collaborative problem-solving (CPS) model to identify participation problems and plausible explanations. In total, 4543 ICF linked codes revealed similarities and differences between individuals. The selected child-cases displayed educational challenges and peer-relational problems. The ICF codes related to activity, body function and environment revealed plausible explanations for the children's documented problems with participation in everyday life. The combination of ICF and CPS can provide a comprehensive view of the child's problems and guide development of participation in everyday life-focused interventions for children treated for brain tumors. Care should be guided by interventions and support directed at individual children and their everyday life. The International Classification of Functioning, Disability and Health (ICF) framework can support identification of the individual child's patterns of problems and how these affects the child's everyday life. It is recommended to start by identifying participation problems when using ICF to identify and describe problems in children's natural settings. The collaborative problem-solving model can guide healthcare, habilitation and school services when identifying and acting on typical and atypical problem patterns experienced by these children.

Background: The functional integration of the jaw and neck motor systems, of great importance to everyday oral activities, is established in early childhood. Detailed characterisation of this developmental progress is largely unknown. Objective: To establish developmental changes in jaw–neck motor function in children over the ages 6–13 years compared to adults. Methods: Jaw and head movement kinematics during jaw opening–closing and chewing were longitudinally recorded in 20 Swedish children (8 girls) at 6 (6.3 ± 0.4), 10 (10.3 ± 0.3) and 13 (13.5 ± 0.7) years of age and 20 adults (9 women, 28.2 ± 6.7). Movement amplitudes, jaw movement cycle time (CT), coefficient of variation (CV) and head/jaw ratio for amplitudes were analysed. Linear mixed effect analysis and Welch's t‐test were used. Results: Children showed pronounced movement variability and longer CT at 6 and 10 years old during opening and chewing (p <.001). Compared to adults, 6‐year‐olds showed higher head/jaw ratios (p <.02) and longer CT (p <.001) during opening and chewing, and higher CV‐head (p <.001) during chewing. Whereas 10‐year‐olds showed larger jaw and head amplitudes (p <.02) and longer CT (p <.001) during opening, and longer CT (p <.001) and higher CV‐head (p <.001) during chewing. For 13‐year‐olds, longer CT (p <.001) during chewing was found. Conclusion: Children showed pronounced movement variability and longer movement cycle time at 6–10 years and developmental progress in jaw–neck integration from 6 to 13 years, with 13‐year‐olds displaying adult‐like movements. These results add new detailed understanding to the typical development of integrated jaw–neck motor function. [ABSTRACT FROM AUTHOR]

The aim of this Swedish study was to explore and describe physiotherapists and occupational therapists' attitudes and understanding of the place of play in habilitation. This was a qualitative study, using semi-structured interviews exploring ten habilitation professional's experiences and attitude towards play. Interviews were analysed using content analysis. The analysis of the interviews resulted in four categories (1) Play in the present or exercise for the future (2) Play is a useful tool (3) Play needs different prerequisites (4) Play is a shared responsibility. The categories represent the professional's attitudes and understanding of play in habilitation. Results demonstrated that enabling play for the sake of play was a low priority in habilitation, despite the acknowledgement that it is a primary concern for children. The professionals focus was mainly on interventions that were remedial: about doing the right thing for the physical body and preparing the child for his/her life as an adult. There is a need to change perspective and incorporate interventions aimed at childhood as well as adulthood. Habilitation professionals need to reframe their anxiety for the future child and reconsider the place of play in practice. [ABSTRACT FROM AUTHOR]

Objectives: Diabetic ketoacidosis (DKA) in type 1 diabetes (T1D) can occur during both insulin pump therapy (continuous subcutaneous insulin infusion, CSII) and insulin injection therapy (multiple daily injections, MDI). The primary aim of this study was to compare CSII and MDI regarding DKA frequency. A secondary aim was to compare metabolic derangement between CSII and MDI at hospital admission for DKA. Research Design and methods: Children 0–17.99 years with established T1D admitted for DKA in Sweden from February 1, 2015 to January 31, 2017 were invited to participate. Data regarding demographics, laboratory data, CSII or MDI, and access to ketone meters and CGM were provided through questionnaires and medical records. The Swedish National Diabetes Registry (SWEDIABKIDS) was used to compare the distribution of CSII and MDI in the national population with the population admitted for DKA, using the chi‐square goodness‐of‐fit test. Distribution of CSII and MDI was then categorized in clinical severity grades for mild (pH 7.20–7.29), moderate (pH 7.10–7.29) and severe DKA (pH <7.10). Results: The distribution of CSII at DKA admission was significantly larger than in the national pediatric population with T1D (74.7% vs. 59.7%, p = 0.002). CSII was overrepresented in mild DKA (85.2% vs. with CSII, p < 0.001), but not in moderate/severe DKA (57.9% with CSII, p = 0.82). Mean HbA1c at hospital admission was 73.9 mmol/mol with CSII and 102.7 mmol/mol with MDI. Conclusions: CSII was associated with higher risk of mild DKA than MDI. MDI was associated with markedly higher HbA1c levels than CSII at hospital admission for DKA. [ABSTRACT FROM AUTHOR]

Objective: To compare the prevalence of parental diabetes between children with and without type 1 diabetes (T1D), and to compare clinical characteristics at diagnosis of T1D in children with, versus without, a family history of diabetes., Research Design and Methods: Parental diabetes among children with T1D was compared with a general population cohort. Clinical characteristics were compared by family history of diabetes in parents and grandparents of 3,603 children with T1D using relative risk (RR) and ANOVA., Results: Children with T1D more often had parents with type 2 diabetes (T2D) (RR 1.88; P < 0.001) than did children without diabetes. Children with T1D and a family history of T2D were more likely to be overweight or obese (P = 0.002)., Conclusions: A family history of T2D and being overweight may contribute to increased risk of T1D., (© 2024 by the American Diabetes Association.)

The aim with the present study was to evaluate the effects and tolerability of Family Meals on Prescription, a 3-month intensive dietary intervention with a participatory approach on body mass index (BMI) and metabolic health in children living with obesity. In this prospective randomized controlled trial, children aged 5-15 years were included from the Pediatric Obesity outpatient Clinics in Halland, Sweden. Participants were randomly assigned to receive lifestyle treatment with or without Family Meals on Prescription (FMP) consisting of a subsidized prepacked grocery bag including recipes and provisions for five Family Meals per week for 3 months. The primary endpoint was changed in BMIz after 3, 12 and 18-24 months and secondary endpoints included to assess tolerability of FMP and effects on metabolic biomarker and frequency of shared meals. Eighty-nine children (51.7% female) entered the study, 54 patients in the intervention group and 35 in the control group. There were no significant differences between the groups concerning gender, age or level of obesity at baseline. The Family Meal on Prescription intervention combined with lifestyle treatment led to a significantly greater reduction in BMIz than lifestyle treatment alone after the 3-month long intervention (- 0.17 vs + 0.01, p < 0.01); however, this difference was not sustained throughout the study period, and in fact, the control group had a greater reduction in BMIz after 18-24 months.A subsidized prepacked grocery bag may be a novel, well-tolerated and effective tool in the treatment of childhood obesity. The fact that the BMIz reduction shown at the end of the intervention did not persist over time emphasized the need of long-term treatment. Registered at clinicaltrals.gov 27 Nov 2020, retrospectively registered: clinicaltrials.gov number 19002468. https://clinicaltrials.gov/study/NCT05225350 What is Known: • Swedish data shows that lifestyle treatment alone is not sufficient for many families undergoing treatment for childhood obesity. • Regular family meals and mealtime routines have been shown to be important for nutritional health and dietary patterns in children and adolescents. What is New: • This intervention with a participatory approach involving prepacked family meals was well tolerated and led to a significant reduction in BMIz during the intervention. • That fact that these results were not sustained over time indicates a need to evaluate longer interventions, and that childhood obesity is a chronic and complex disease which requires long-time treatments., (© 2024.

Aims: The present analysis estimated the cost-effectiveness of treatment with the Tandem t: slim X2 insulin pump with Control IQ technology (CIQ) in children with type 1 diabetes in Sweden., Methods: A four-state Markov model and probabilistic sensitivity analyses (PSA) were used to assess the cost-effectiveness of CIQ use compared with treatment with multiple daily insulin injections (MDI) or continuous subcutaneous insulin infusion (CSII) in conjunction with CGM. Data sources included clinical input data from a recent retrospective, observational study, cost data from local diabetes supply companies and government agencies, and published literature. Outcomes measures were quality adjusted life years (QALYs) at 10, 20 and 30-year time horizons based on cost per QALY and incremental cost-effectiveness ratio (ICER)., Results: A total of 84 type 1 diabetes children were included (CIQ, n = 37; MDI, n = 19; CSII, n = 28). For all time horizons, the use of CIQ was a dominant strategy (e.g. more effective and less costly) compared with MDI or CSII use: 10-year ICER, SEK -88,010.37 and SEK -91,723.92; 20-year ICER, SEK -72,095.33 and SEK -87,707.79; and 30-year ICER, SEK -65,573.01 and SEK -85,495.68, respectively. PSA confirmed that CIQ use was less costly compared with MDI and CSII., Conclusions: Initiation of CIQ use in children with type 1 diabetes is cost-saving, besides previously shown improved glycaemic control, and increased quality of life. Further investigations are needed to more fully elucidate the cost-effectiveness of these technologies in different countries with existing differences in payment models., (© 2024 The Author(s).

Objectives: In gastroschisis, the intestines are exposed to amniotic fluid during pregnancy. The defect in the abdominal wall may also compress the mesentery and impair the intestinal blood supply. There is a varying degree of intestinal damage at birth. Complex gastroschisis is defined as gastroschisis with severe complications such as intestinal atresia, volvulus, necrosis and perforation. The aim of this study was to investigate long-term gastrointestinal morbidity and compare simple and complex cases., Methods: A nation-wide retrospective cohort study with data from national registers was conducted. All children born with gastroschisis in Sweden from 1 January 1997 to 31 December 2016 were included in the study. Exposure was complex gastroschisis and the primary outcomes were intestinal failure and bowel obstruction., Results: The study included 315 cases with gastroschisis, 260 classifieds as simple gastroschisis and 55 as complex. The median time to follow was 8 years. A significantly higher risk of developing intestinal failure (hazard ratio [HR]: 11.7) was found in complex cases. Nine percent of the complex cases underwent autologous gastrointestinal reconstructive surgery for intestinal failure, none of the simple cases did. The complex cases had a higher risk for bowel obstruction (HR: 4.3) with a higher proportion requiring surgery (18.2% vs. 6.9%) compared to simple cases., Conclusions: This nationwide study showed that the risk for intestinal failure and bowel obstruction is significantly higher for children with complex gastroschisis compared to simple gastroschisis. Most of the events occurred during the first 2 years of life., (© 2024 The Author(s).

Aim: This study aimed to compare outcomes post-admission to a Swedish paediatric intensive care unit (PICU) in children with complex chronic conditions (CCC) and without CCC., Methods: In this observational registry-based study, consecutive admissions to the Astrid Lindgren Children's Hospital PICU from 1 January 2008 to 31 December 2016 were analysed. Data on demographics, predicted death rates (PDR), admission diagnoses and causes of death were collected. Mortality was recorded up to 15 years after admission and compared between groups., Results: Patients with CCC constituted 64.6% (n = 3026) of PICU admissions and 83.5% (n = 111) of PICU deaths. The crude mortality rate in PICU was 2.84% overall. CCC-patients were 2.83 times more likely to die in PICU compared to non-CCC (OR 2.83; 95% CI: 1.78-4.49). Mortality increased in the CCC-cohort up to 5 years after PICU discharge, while non-CCC patients generally survived if they survived in PICU. Of the patients who died in PICU, the median PDR was 22.9% for CCC-patients and 66.5% in the non-CCC cohort., Conclusion: Children with CCC accounted for most admissions and deaths in PICU. Despite lower severity of illness scores upon admission, CCC patients were nearly three times more likely to die in PICU compared to non-CCC patients., (© 2024 The Author(s).

Objectives: Telehealth and home spirometry feasibility for children has been established, but their impact on cystic fibrosis (CF) disease progression remains unassessed. We aimed to evaluate the effects of telehealth and home spirometry on CF disease progression and care., Methods: Children with CF aged 5-17 years from all Swedish CF centers were provided with home spirometers. A minimum of two in-person visits were replaced with telemedicine visits and participants were instructed to conduct home spirometry before visits. Linear mixed-effects models were used to compare annual CF disease trajectories during the intervention period and prepandemic period (1 January 2019 to 28 February 2020). Participants and caregivers completed study questionnaires., Results: A total of 59 individuals completed the study over a mean (SD) period of 6.8 (1.4) months, made 3.1 (1.0) physical visits and 2.2 (0.6) telehealth visits per patient year during the study period. The mean difference (95% CI) between the intervention and prepandemic period progression rate for FEV 1 %, lung clearance index and BMI were -0.4 (-1.3 to 0.5, p = 0.39), 0.11 (-0.07 to 0.28, p = 0.25) and -0.02 (-0.13 to 0.08, p = 0.70), respectively. There were no major shifts in the incidence of airway pathogens, sputum cultures, or antibiotics use between the periods (p > 0.05). The intervention did not increase stress. Almost all participants and caregivers expressed a desire to continue with home spirometry and telemedicine., Conclusion: Combining telehealth and physical visits with access to home spirometry demonstrated comparable effectiveness as exclusively in-person care with enhanced flexibility and personalization of CF care., (© 2024 The Author(s).

Aim: To identify on a population basis the prevalence of autism and attention-deficit/hyperactivity disorder (ADHD) in children with Dravet syndrome and factors associated with symptoms of autism and ADHD., Method: Forty-one of 48 children with Dravet syndrome living in Sweden, born between 1st January 2000 and 31st December 2018 underwent assessment including measures of autism and ADHD. Diagnoses of autism and ADHD were made with respect to DSM-5 criteria. Factors associated with features of autism and ADHD were analysed via regression., Results: Twenty-five of the 41 children fulfilled DSM-5 criteria for autism spectrum disorder and 12 of 37 children considered for an ADHD diagnosis fulfilled DSM-5 criteria for ADHD. Severe intellectual disability was significantly associated with a greater degree of autistic features (p < 0.001) and a DSM-5 diagnosis of autism spectrum disorder (p = 0.029). Younger children had significantly more features of ADHD (p = 0.004) and features of inattention were significantly more common than features of hyperactivity/impulsivity (p < 0.001)., Interpretation: Children with Dravet syndrome often have significant features of autism and ADHD, primarily inattentive type. Screening for autism and ADHD should be routine in children with Dravet syndrome., What This Paper Adds: In total, 25 of 41 assessed children with Dravet syndrome fulfilled DSM-5 criteria for autism. Twelve of 37 assessed children with Dravet Syndrome met DSM-5 criteria for attention-deficit/hyperactivity disorder (ADHD). Severe intellectual disability was significantly associated with a greater degree of autism spectrum disorder features. Younger children had significantly more features of ADHD., (© 2024 Mac Keith Press.)

Background: Early childhood caries (ECC) has been found to be up to five times more common among children living in areas of low socio-economic status (SES) than among children in areas of higher SES., Aim: To evaluate an ECC prevention programme from pregnancy to 3 and 6 years of age., Design: A prospective, controlled, intervention cohort study was initiated in 2013 in a low-SES area in Sweden. The intervention group received an individual interdisciplinary ECC prevention programme starting pre-birth, consisting of supportive oral health-promoting talks using motivational interviewing techniques and individual ECC preventive actions. A control group, consisting of pregnant women living in a comparable area, received ordinary routines., Results: Of the 336 pregnant women, 64 mothers (with 64 children) completed the programme, and 394 children were born in the control group. At the sixth year examination, the proportion of children with no caries was similar between the groups (53% resp. 52%, p = .976), whereas the proportion with decayed, missed, filled primary teeth (dmft = 1-5) was slightly lower (23% resp. 36%, p = .063), and the proportion with severe caries disease (dmft > 5) was higher (p = .013) in the intervention group (25%) than in the control group (12%)., Conclusion: No preventive effect regarding caries can be demonstrated at sixth year of age. Maternal behavioural change in dental care was not sufficient to even out inequalities in oral health in children, eventually due to difficulties in reaching the target group and the lack of effects among the families reached., (© 2024 The Authors.

Background: Osteonecrosis (ON) is a potentially disabling skeletal complication of cancer treatment. Although symptomatic osteonecrosis (sON) is well-known in acute lymphoblastic leukemia (ALL), with an incidence around 6%, studies on sON in pediatric Hodgkin lymphoma (HL) are scarce. The aim of this study was to examine the incidence, risk factors, and outcome of sON in children treated for HL., Procedure: A total of 490 children under 18, diagnosed with HL between 2005 and 2019 in Sweden, Finland, and Denmark were eligible for the study. Data on patient characteristics, HL treatment, and development of sON were collected from patients' medical records. Magnetic resonance imaging scans were used to establish ON diagnosis and grade ON according to the Niinimäki grading system., Results: Cumulative 2-year incidence of sON among the 489 included patients was 5.5% (n = 30). The risk for developing sON was higher for those with older age (odds ratio [OR] 1.25, 95% confidence interval [CI]: 1.05-1.49, p < .010), female sex (OR 4.45, CI 1.87-10.58, p < .001), high total cumulative glucocorticoid (GC) doses (OR 1.76, 95% CI: 1.21-2.56, p = 0.003), and advanced HL (OR 2.19, 95% CI: 1.03-4.65, p = .042). Four (13.3%) patients underwent major surgical procedures and 13 (43.3%) had persistent symptoms due to ON at follow-up., Conclusions: This study shows that sON is as common in pediatric HL as in pediatric ALL, with risk factors such as older age, female sex, high cumulative GC doses, and advanced HL. Future HL protocol development should aim to reduce the burden of ON by modifying GC treatment., (© 2024 The Author(s). Pediatric Blood & Cancer published by Wiley Periodicals LLC.)

Background: Alpine skiing is practiced with speed and forces which entails a risk of injury and fractures. Most studies focus on all injuries in the musculoskeletal system and fractures are only described briefly or lack comparison between children and adults. This study focuses on the national trends of skiing-related fractures in children and adults, detailing fracture localization characteristics and initial treatments., Methods: This is a population-based national cohort study using data from the Swedish Fracture Register. The study population includes children and adults with a fracture sustained by alpine skiing between January 2015 and April 2022. Variables of interest were age, sex, localization of the fracture and segment, the number of fractures per patient, injury date, open or closed fracture, energy level, and primary treatment., Results: In total 7,110 fractures were registered in 6,806 patients. 48.6 % of the fractures were in children The women had a statistically significant higher median age at fracture to men. In children, it was contrary with a statistically lower median age in girls compared to boys. Children most commonly fractured the tibia (48.4 %), the radius (22.2 %), and the hand (7.8 %). The most fractured segment in children was the tibial shaft (38.5 %). Adults most often fractured the tibia (27.6 %), the radius (13.9 %), and the humerus (13.6 %) and had the proximal tibia as the most fractured segment (18.8 %). 82 % (2724) of fractures in children were treated non-surgically. In adults, 54 % (1850) were treated non-surgically., Conclusion: Tibia fractures were predominant, with children frequently experiencing shaft fractures and adults proximal tibia fractures. Younger, lighter children skiing at a slower speed would benefit from improved ski bindings for fracture prevention. Tailoring ski equipment to an individual's age and sex is crucial for enhancing preventive strategies., Competing Interests: Declaration of competing interest None, (Copyright © 2024.

Aim: To assess experience of care, well-being of parents and children's development in a cohort of extremely premature infants born <24 weeks of gestation in Sweden from 2007 to 2018., Methods: A survey based on multiple questionnaires answered by 124/349 (35.5%) parents., Results: The median age of parents and children was 43 and 9 years, respectively; 74.2% were mothers. Parents expressed high healthcare satisfaction. Following discharge from neonatal care, the satisfaction with the infant's treatment, support from personnel and being respected as a parent significantly declined but remained high. The criteria for suspected developmental deviation according to the screening test early symptomatic syndromes eliciting neurodevelopmental clinical examinations-questionnaire was fulfilled by 84.3%, 55.6% had suspected avoidant restrictive food intake disorder and 47.9% had visual perception problems. Parents experienced severe fatigue (48.6%) despite strong social support and family self-efficacy. Economic support was provided to 30.6%, and 37.9% of children were enrolled in habilitation services., Conclusion: This study highlighted the substantial challenges faced by parents of infants born before 24 weeks of gestation, including decreased satisfaction post-discharge, fatigue and concerns about children's well-being. The findings underscore the need for comprehensive family-centred support and long-term multi-professional follow-up centres., (© 2024 The Author(s).

Background: Psychosomatic complaints have increased among adolescents in recent decades, as have overweight and obesity rates. Both of these trends are regarded as public health concerns. However, the associations between weight status and psychosomatic complaints are not yet clear, necessitating further research. The aim of the present study was to investigate the associations between weight status and psychosomatic complaints in Swedish adolescent boys and girls, as well as to explore the potential buffering effect of family support., Methods: The data was obtained from the cross-sectional Swedish Health Behaviour in School-aged Children (HBSC) study conducted in 2017/18, which involved 3,135 students aged 11, 13, and 15 years. Weight status was based on self-reported information on weight and height, which allowed for the calculation of body mass index (BMI) and the categorisation of participants into three groups: non-overweight, overweight, and obese. Psychosomatic complaints were assessed based on information regarding the frequency of eight different complaints, which were summed into an index. Family support was measured using three items describing the level of perceived emotional support, and an index was created, which was dichotomised into low and high family support. Gender stratified linear regression models were run to examine the associations between weight status and psychosomatic complaints. Age and family affluence were included as covariates. Interaction terms were included to evaluate whether family support moderated the main association., Results: Obesity was associated with higher levels of psychosomatic complaints in both boys and girls when compared to being non-overweight (boys: b = 2.56, 95% CI 0.32, 4.79; girls: b = 3.35, 95% CI 0.77, 5.94), while being overweight did not show any statistically significant associations with the outcome (boys: b = 0.21, 95% CI -0.72, 1.15; girls: b = 0.78, 95% CI -0.42, 1.98). In girls, a statistically significant interaction effect between family support and weight status was observed (p = 0.031), indicating that family support buffered against psychosomatic complaints in girls with obesity. No statistically significant interaction was found for boys (p = 0.642)., Conclusions: The findings of this study highlight the importance of public health initiatives aimed at preventing childhood obesity. They also underscore the significant role of family support in reducing psychosomatic complaints among adolescents with obesity. Further research is necessary to gain a deeper understanding of these relationships., (© 2024. The Author(s).)

Background: Recent studies have suggested an increasing prevalence of intellectual disability diagnoses in some countries. Our aim was to describe the trend in the prevalence of intellectual disability diagnoses in Sweden and explore whether associated sociodemographic and perinatal factors can explain changes in the prevalence., Methods: We used a register-based nationwide cohort of residents in Sweden born between 2001 and 2011. We calculated the prevalence of intellectual disability diagnoses by age 10 for each birth cohort and the prevalence ratios in relation to the baseline year 2011, overall and by severity of intellectual disability, and comorbidity of autism and attention-deficit/hyperactivity disorder. The prevalence ratios were stratified and adjusted for associated sociodemographic and perinatal factors., Results: Among 1,096,800 individuals, 8,577 were diagnosed with intellectual disability by age 10. Among these, 3,949 (46%) and 2,768 (32%) were also diagnosed with autism and attention-deficit/hyperactivity disorder, respectively, and 4% were diagnosed with profound, 8% severe, 20% moderate, 52% mild, and 16% other/unspecific intellectual disability. The recorded age-10 prevalence of intellectual disability diagnoses increased from 0.64% (95% confidence interval 0.59-0.69%) in 2011 to 1.00% (0.94-1.06%) in 2021, corresponding to an annual prevalence ratio of 1.04 (1.04-1.05). The increase was, however, restricted to mild, moderate, and other/unspecific intellectual disability diagnoses, while the trends for profound and severe intellectual disability diagnoses were stable. The increasing trend was perhaps less pronounced among females and children with diagnosed attention-deficit/hyperactivity disorder, but independent of the co-occurrence of autism. The prevalence ratios did not change with stratification or adjustment for other associated demographic and perinatal factors., Conclusion: The recorded prevalence of diagnosed mild and moderate intellectual disability among 10-year-olds in Sweden has increased over the recent decade. This increase could not be explained by changes in associated sociodemographic or perinatal factors, including birth weight, gestational age, and parental age, migration status, and education at the child's birth. The increase instead may be due to changes in diagnostic practices in Sweden over time., (© 2024. The Author(s).)

Background and Objectives: Muscular dystrophies and myotonic disorders are genetic disorders characterized by progressive skeletal muscle degeneration and weakness. Epidemiologic studies have found an increased cancer risk in myotonic dystrophy, although the cancer risk spectrum is poorly characterized. In patients with muscular dystrophy, the cancer risk is uncertain. We aimed to determine the overall cancer risk and cancer risk spectrum in patients with muscular dystrophy and myotonic dystrophy using data from the Swedish National registers., Methods: We performed a matched cohort study in all patients with muscular dystrophy or myotonic dystrophy born in Sweden 1950-2017 and 50 matched comparisons by sex, year of birth, and birth county per individual. The association with cancer overall and specific malignancies was estimated using stratified Cox proportional hazard models., Results: We identified 2,355 and 1,968 individuals with muscular dystrophy and myotonic dystrophy, respectively. No increased overall cancer risk was found in muscular dystrophy. However, we observed an increased risk of astrocytomas and other gliomas during childhood (hazard ratio [HR] 8.70, 95% CI 3.57-21.20) and nonthyroid endocrine cancer (HR 2.35, 95% CI 1.03-5.34) and pancreatic cancer (HR 4.33, 95% CI 1.55-12.11) in adulthood. In myotonic dystrophy, we found an increased risk of pediatric brain tumors (HR 3.23, 95% CI 1.16-9.01) and an increased overall cancer risk in adults (HR 2.26, CI 1.92.2.66), specifically brain tumors (HR 10.44, 95% CI 7.30-14.95), thyroid (HR 3.92, 95% CI 1.70-9.03), and nonthyroid endocrine cancer (HR 7.49, 95% CI 4.47-12.56), endometrial (HR 8.32, 95% CI 4.22-16.40), ovarian (HR 4.00, 95% CI 1.60-10.01), and nonmelanoma skin cancer (HR 3.27, 95% CI 1.32-8.13)., Discussion: Here, we analyze the cancer risk spectrum of patients with muscular dystrophy and myotonic dystrophy. To the best of our knowledge, this is the first report of an increased risk for CNS tumors in childhood and adult nonthyroid endocrine and pancreatic cancer in muscular dystrophy. Furthermore, for myotonic dystrophy, we confirmed previously reported associations with cancer and expanded the cancer spectrum, finding an unreported increased risk for nonthyroid endocrine cancer. Additional studies confirming the cancer risk and delineating the cancer spectrum in different genetic subtypes of muscular dystrophies are warranted before considering altered cancer screening recommendations than for the general population.

Background: The number of adolescents reporting that they are stressed has more than doubled among both boys and girls. Most focus is given to girls because they typically not only report higher levels of stress but also feel stressed more frequently than boys do. However, studies have confirmed that boys' experience of stressors is the same, implying that genders are equally prone to experiencing stress. Although male and female adolescents appear to experience stress in a similar way, how they cope with these stressors might differ. This study focused on boys' experiences of stress and how they cope with it., Method: Eight focus groups were conducted with 39 adolescent boys aged 12-19 years enrolled in four schools in southern Sweden. The data was analysed inductively with conventional content analysis., Results: The analysis resulted in three categories: Stress perception - time as a key factor, Identifying stressors and levels of stress, and Silent struggles and distractions. The boys had experienced considerable stress in their lives, despite their limited understanding of the concept. Their coping skills focused on engaging in sports or distracting themselves from stressors while relying less on social support from peers, school staff, or family., Conclusions: Adolescent boys might need assistance in identifying stress and clearly voicing their specific concerns. They should also be provided with spaces that are free from stigmatization and judgement. Parents, teachers, and school nurses should be equipped with the appropriate tools and education on how to discuss stress and mental health in general with adolescent boys to prevent possible negative long-term consequences for both their physical and mental health., (© 2024.

Background: There is no consensus or clinical guidelines for screening routines of autoimmune disease in individuals with juvenile idiopathic arthritis (JIA), since results are conflicting whether the risk for such conditions is increased or not among individuals with JIA. The aim of this study was to investigate if the frequency of comorbid autoimmune conditions is increased after JIA diagnosis in a validated population-based JIA cohort in southern Sweden., Methods: Autoimmune comorbidities were evaluated in a pre-existing population-based JIA cohort of 302 participants, constituting of individuals diagnosed with a validated JIA diagnosis 2000-2010 in southern Sweden. The comorbidities were determined through analysis of diagnosis codes registered after the JIA diagnosis and until 2019. With the use of a reference population of 1510 age- and sex matched individuals, hazard ratios (HR) were calculated with Cox proportional models., Results: During the study period, 7.7% of the JIA cohort received an autoimmune diagnosis after their JIA diagnosis. Individuals with JIA had an increased risk of autoimmune diseases in general (HR 4.11, 95% CI 2.13-7.91) within the first 7 years of disease, as well as separately for coeliac disease (HR 5.24, 95% CI 1.76-15.65) and hypothyroidism (HR 3.74, 95% CI 1.14-12.30) compared to the reference population. Antinuclear antibody (ANA) positivity was associated with a significantly increased risk of comorbid autoimmune disease in the JIA cohort, with HR 6.21 (95% CI 1.64-23.55) for ANA positive individuals., Conclusions: Individuals with JIA have a significantly increased risk of being diagnosed with an autoimmune condition after receiving their JIA diagnosis compared to matched references. ANA positivity is associated with a further increased risk. Our results emphasize awareness in physicians of additional autoimmune disorders in individuals with JIA and advocate serological screening of autoimmune conditions during follow-up., (© 2024.

Background: A self-harm episode is a major risk factor for repeat self-harm. Existing tools to assess and predict repeat self-harm have major methodological limitations, and few are externally validated., Objective: To develop and validate a risk assessment model of repeat self-harm up to 6 months after an episode of non-fatal self-harm that resulted in an emergency visit to hospital or specialised care., Methods: Using Swedish national registers, we identified 53 172 people aged≥10 years who self-harmed during 2008-2012. We allocated 37 523 individuals to development (2820 or 7.5% repeat self-harm incidents within 6 months) and 15 649 to geographic validation (1373 repeat episodes) samples, based on region of residence. In a temporal validation of people who self-harmed during 2018-2019, we identified 25 036 individuals (2886 repeat episodes). We fitted a multivariable accelerated failure time model to predict risk of repeat self-harm., Findings: In the external validations (n=40 685), rates of repeat self-harm were 8.8%-11.5% over 6 months. The final model retained 17 factors. Calibration and discrimination were similar in both validation samples, with observed-to-expected ratio=1.15 (95% CI=1.09 to 1.21) and c-statistic=0.72 (95% CI=0.70 to 0.73) in the geographical validation. At 6 months and a 10% risk cut-off, sensitivity was 51.5% (95% CI=48.8% to 54.2%) and specificity was 80.7% (95% CI=80.1% to 81.4%) in geographic validation; corresponding values were 56.9% (95% CI=55.1% to 58.7%) and 76.0% (95% CI=75.5% to 76.6%) in temporal validation. Discrimination was slightly worse at the 1-month prediction horizon (c-statistics of 0.66-0.68)., Conclusions: Using mostly routinely collected data, simple risk assessment models and tools can provide acceptable levels of accuracy for repeat of self-harm., Clinical Implications: This risk model (OXford SElf-harm repeat tool) may assist clinical decision-making., Competing Interests: Competing interests: HL reports receiving grants from Shire Pharmaceuticals; personal fees from and serving as a speaker for Medice, Shire/Takeda Pharmaceuticals and Evolan Pharma AB; all outside the submitted work.

Background: Malaria remains a significant public health concern, especially for the deadliest parasite, Plasmodium falciparum. During acute malaria, various cytokines, including osteopontin (OPN), regulate the immune response. OPN has been shown to be protective against malaria in mice. Nonetheless, its precise function and potential ability to control parasites during acute malaria in humans remain poorly understood., Results: Blood samples were collected from Swedish adults with imported malaria, Ugandan children and adults with symptomatic malaria (including follow-up after 42 days), Ugandans with non-malarial fever and healthy individuals from both Uganda and Sweden. Parasitemia was determined by microscopy. Malaria-negative samples were verified by LAMP. OPN and interferon-γ (IFN- γ) levels were measured using ELISA. In children, OPN levels were significantly higher during acute infection compared to levels after 42 days, whereas Ugandan adults showed no difference. Swedish adults with imported malaria had elevated OPN levels compared to both Swedish controls and Ugandan adults with malaria. Parasitemia was significantly correlated with both OPN and IFN-γ levels across the entire cohort. While a significant correlation between OPN and IFN-γ was evident overall, it remained statistically significant only in Ugandan adults when analyzed by subgroups. This suggests that OPN is not just a general marker of inflammation but may be regulated differently during the development of malaria immunity., Conclusions: In acute malaria, elevated OPN levels showed a stronger correlation with lack of immunity than age. These findings underscore the potential importance of OPN in malaria, particularly in non-immune individuals., (© 2024. The Author(s).)

Introduction: Traumatic peripheral nerve injuries pose significant challenges to healthcare systems and individuals, affecting sensory function, causing neuropathic pain, and impairing quality of life. Despite their impact, comprehensive studies on the epidemiology and regional variance of these injuries are scarce. Understanding the incidence, trends, and anatomical distribution of such injuries is essential for targeted interventions and resource allocation., Methods: This observational study utilized register-based data from the Swedish National Patient Register covering the period from 2008 to 2022. Incidence rates, trends, and anatomical distribution of traumatic peripheral nerve injuries were analyzed using descriptive statistics, Poisson regression modeling, and regional comparisons., Results: Higher incidences of peripheral nerve injuries were observed among men compared to women across all age groups. The hand and wrist were the most commonly affected sites. Regional variations in incidence rates were evident, with some regions consistently exhibiting higher rates compared to others. Notably, a decreasing trend in injuries was observed over the study period., Conclusion: This study underscores the importance of targeted interventions and preventive strategies, considering sex, age, and regional disparities. Further research incorporating individual patient-level data is warranted to enhance our understanding and inform tailored interventions to reduce the burden of these injuries., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Magnéli, Axenhus.

Background: Screen time among children and adolescents has increased dramatically, raising concerns about its impact on development and mental health. While research highlights both potential benefits and risks, excessive use has been linked to issues like anxiety, depression, and gaming addiction. Despite growing concern, effective interventions are scarce. Recognizing the importance of family dynamics in child development, we propose a family-centered program to address problematic gaming and excessive screen use in a clinical population. By involving both children and parents, we aim to create a more comprehensive approach to prevention and treatment., Objective: This study aims to determine the possibility of distributing and evaluating a family-centered group program for problematic gaming and excessive screen use (FAME) in a clinical child and adolescent psychiatry (CAP) population. We will monitor the recruitment rate; track the retention and attendance rates of both parents and children; and assess whether each session's objectives are met, the content is delivered within the allotted time, and the necessary resources (eg, facilitators and materials) are available. Additionally, we will gather qualitative and quantitative feedback from participants through postprogram surveys and individual interviews with both children and parents., Methods: A total of 10 families with ongoing contact with CAP in Skåne, Sweden, will be recruited and offered participation in a family-centered group program targeting children aged 10-18 years with reported difficulties regarding screen gaming or screen use. The intervention to be tested is a newly developed, family-centered, psychoeducational, cognitive behavioral therapy-based intervention addressing both positive and negative aspects of screen use; setting boundaries; the connection between thoughts, feelings, and behaviors; conflict triggers; and sleep hygiene. The primary goal of the pilot study is to test the feasibility of the program, as well as recruitment and the analysis of participants' experiences with the program., Results: A total of 11 children and their parents were enrolled during first quarter of 2024. A 4-session pilot was delivered in first quarter of 2024, and the first results are expected in the third quarter of 2024., Conclusions: The overarching goal of this pilot study is to determine the possibility of distributing and evaluating a family-centered group program for problematic gaming and excessive screen use (FAME) in a clinical CAP population. The insights gained from this study will guide our future research, which will focus on conducting a larger-scale evaluation of the intervention's impact on family screen time conflicts and inform future strategies for the implementation of family-centered interventions in child and youth clinics., Trial Registration: ClinicalTrials.gov NCT06098807; https://clinicaltrials.gov/study/NCT06098807., International Registered Report Identifier (irrid): DERR1-10.2196/56387., (©Marie Werner, Sabina Kapetanovic, Emma Claesdotter-Knutsson.

Background and Aims: A variety of maternal heart conditions are associated with abnormal placentation and reduced foetal growth. However, their impact on offspring's long-term cardiovascular health is poorly studied. This study aims to investigate the association between intrauterine exposure to pre-existing maternal cardiovascular disease (CVD) and offspring CVD occurring from infancy to early adulthood, using paternal CVD as a negative control., Methods: This nationwide cohort study used register data of live singletons without major malformations or congenital heart disease born between 1992 and 2019 in Sweden. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models, adjusted for essential maternal characteristics. Paternal CVD served as a negative control for assessment of unmeasured genetic and environmental confounding., Results: Of the 2 597 786 offspring analysed (49.1% female), 26 471 (1.0%) were born to mothers with pre-existing CVD. During a median follow-up of 14 years (range 1-29 years), 17 382 offspring were diagnosed with CVD. Offspring of mothers with CVD had 2.09 times higher adjusted HR of CVD (95% CI 1.83, 2.39) compared with offspring of mothers without CVD. Compared with maternal CVD, paternal CVD showed an association of smaller magnitude (HR 1.49, 95% CI 1.32, 1.68). Increased hazards of offspring CVD were also found when stratifying maternal CVD into maternal arrhythmia (HR 2.94, 95% CI 2.41, 3.58), vascular (HR 1.59, 95% CI 1.21, 2.10), and structural heart diseases (HR 1.48, 95% CI 1.08, 2.02)., Conclusions: Maternal CVD was associated with an increased risk of CVD in offspring during childhood and young adulthood. Paternal comparison suggests that genetic or shared familial factors may not fully explain this association., (© The Author(s) 2024.

Background: In Sweden, surgical treatment of Hirschsprung's disease (HSCR) was centralized from four to two pediatric surgery centers 1st of July 2018. In adults, centralization of surgical care for complex or rare diseases seems to improve quality of care. There is little evidence supporting centralization of pediatric surgical care. The aim of this study was to assess surgical management and postoperative outcome in HSCR patients following centralization of care., Methods: This study retrospectively analyzed data of patients with HSCR that had undergone pull-through at a pediatric surgery center in Sweden from 1st of July 2013 to 30th of June 2023. Patients managed from 1st of July 2013 to 30th of June 2018 (before centralization) were compared with patients managed from 1st of July 2018 to 30th of June 2023 (after centralization) regarding surgical treatment, unplanned procedures under general anesthesia or readmissions up to 90 days after pull-through as well as complications classified according to Clavien-Madadi up to 30 days after pull-through., Results: In the 5-year period prior to centralization, 114 individuals from 4 treating centers were included and compared to 83 patients from 2 treating centers in the second period. There was no difference regarding age at pull-through or proportion of patients with a stoma prior to pull-through. An increase of laparoscopically assisted endorectal pull-through (8.8% to 39.8%) was observed (p < 0.001). No significant differences were seen in postoperative hospital stay, unplanned procedures under general anesthesia, or readmissions up to 90 days after pull-through. There was no difference in severe complications (Clavien-Madadi ≥ 3); however, HAEC treated with antibiotics increased following centralization (10.5-24.1%; p = 0.018)., Conclusion: Centralization of care for HSCR does not seem to delay time to pull-through nor reduce severe complications, unplanned procedures under general anesthesia or readmissions up to 90 days after pull-through. The increased HAEC rate may be due to increased awareness of mild HAEC., Level of Evidence:  Level III., (© 2024. The Author(s).)

Background: Ecological observations suggest a negative relationship between childhood socioeconomic status (SES) and inflammatory bowel disease (IBD) risk. Individual-level analyses have been inconsistent and mostly lacked refined assessments of SES. We aimed to comprehensively study the association between early-life SES and later IBD., Methods: This study included 117 493 participants from the Norwegian Mother, Father and Child cohort and Swedish All Babies in Southeast Sweden cohorts. Participants were followed from birth (1997-2009) through 2021. IBD was identified through national patient registers. Questionnaire and register data were used to define parental educational level, employment, and household income level. Cox regression estimated adjusted hazard ratios (aHRs), accounting for other SES exposures and covariates (eg, parental IBD). Cohort-specific estimates were pooled using a random-effects model., Results: During 2 024 299 person-years of follow-up, 451 participants were diagnosed with IBD (All Babies in Southeast Sweden cohort, n = 113 and Norwegian Mother, Father and Child cohort, n = 338). Early-life maternal, but not paternal, educational level was associated with later IBD (low vs high educational level; pooled aHR, 1.81; 95% confidence interval [CI], 1.16-2.82; and pooled aHR, 1.20; 95% CI, 0.80-1.80; respectively). Having a nonworking mother or father was not significantly associated with IBD (pooled aHR, 0.69; 95% CI, 0.47-1.02; pooled aHR, 0.79; 95% CI, 0.45-1.37). High vs low household income level yielded a pooled aHR of 1.33 (95% CI, 0.94-1.89). Overall, results were largely consistent across cohorts., Conclusions: In this prospective Scandinavian cohort study, low maternal educational level was, independent of other SES and covariates, significantly associated with later IBD in her child. Further research is needed to elucidate factors that may mediate this relationship., (© 2023 Crohn’s & Colitis Foundation.

Background: Early support for children and families in need can improve children's health and development. In a Swedish region, a new working model called Safe Environment for Every Kid (SEEK) was introduced in the Child Health Services to facilitate the early identification of psychosocial risk factors., Objective: The aim of this study was to describe the adoption and introduction of the SEEK model in the Child Health Services of Region Jönköping County., Methods: Quantitative data were analysed using descriptive statistics, whereas qualitative data were analysed separately by a thematic approach. The results were then interpreted together with documents (including CHS management meeting notes and documents describing planning and training sessions) using an exploratory mixed-methods approach to give a comprehensive description of the adoption and introduction of the SEEK model., Results: The results show that the SEEK model improved coordination and collaboration, which led to better integrated care for children and families. The structure was regarded as supportive when introducing the SEEK model in Child Health Services. The questionnaire, as part of the SEEK model, was used in 88% of possible health visits. The most reported reason for not using it was a lack of time., Conclusions: The desire to make a difference and thereby promote better health and development for children was a crucial factor for the nurses in adopting the SEEK model in their clinical practice. The design using coaches was also appreciated and supported the adoption and introduction of the SEEK model., Patient or Public Contribution: Parents and healthcare professionals did not contribute to the research process. The results are based on dialogues between CHS nurses and parents after the parents filled in the SEEK questionnaire, providing an understanding of professional relationships when dealing with challenging issues., (© 2024 The Author(s).

Background: Trajectories of asthma and allergy in children are heterogeneous and commonly derived from parental report of disease or clinical records. This study combined parental-reported and register-based dispensed medication data to characterize childhood trajectories of co-existing asthma, allergic rhinitis, and eczema., Methods: From a Swedish population-based birth cohort (N = 5654), survey responses collected at the age of 1, 4.5, 8, and 12 years were linked to dispensed medication register data for the period of 2-13 years. Trajectories were identified with latent class analysis. Statistical metrics and clinical interpretability guided the model selection., Results: Nine distinct trajectories were identified: three asthma-dominated (early-onset remitting [n = 189, 3.3%], late-onset [n = 117, 2.1%], and persistent [n = 149, 2.6%]), two eczema-dominated (persistent [n = 190, 3.4%] and remitting [n = 432, 7.6%]), one allergic rhinitis-dominated (late-onset [n = 259, 4.6%]), two multimorbidity (mid-childhood asthma and late-onset allergic rhinitis [n = 144, 2.5%], and persistent eczema and late-onset allergic rhinitis [n = 90, 1.6%]), and one low-disease burden trajectory (n = 4084, 72.2%). Differences were seen across the trajectories in the proportion of parental report of disease and dispensed medication as well as by class and quantity of medication dispensed., Conclusion: Combined parental-reported and dispensed medication data enriches characterization of longitudinal trajectories of asthma and allergy in children by merging subjective experience of disease with healthcare utilization. The identified trajectories were characterized by distinct disease development and prescription patterns suggesting clinically differential morbidity burden., (© 2024 The Author(s).

Introduction: Both suicide and self-harm are disproportionately common in autistic people. Sex differences in risk of self-harm and suicide are observed in the general population, but findings are mixed for autistic people. Self-cutting may be a particularly risky self-harm behaviour for suicide in autistic people. We aimed to explore sex differences and differences in method of self-harm in the association between self-harm and suicide in autistic and non-autistic adolescents and young adults., Methods: We used a total population register of 2.8 million Swedish residents. Participants were followed from age 12 until December 2021 for medical treatment because of self-harm, and death from suicide. We used Cox proportional hazard regression models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for risk of death from suicide following self-harm, and Relative Excessive Risk due to Interaction (RERI) to explore the interaction between self-harm and autism in females and males., Results: We identified 85,143 autistic individuals (31,288 female; 53,855 male) and 2,628,382 non-autistic individuals (1,286,481 female; 1,341,901 male) aged 12-37 years. Incidence of suicide following self-harm was higher in autistic males (incidence per 100,000 risk-years = 169.0 [95% CI 135.1, 211.3]) than females (125.4 [99.4, 158.3]). The relative risk was higher for autistic females (HR 26.1 [95% CI 20.2, 33.7]) than autistic males (12.5 [9.9, 15.8]). An additive effect of both autism and self-harm was observed in both females (RERI = 9.8) and males (2.0). Autistic individuals who self-harmed through cutting were at greatest risk of death from suicide (HR 25.1 [17.9, 35.2]), compared to other methods., Conclusion: Autistic males and females are at increased risk of death from suicide following severe self-harm, particularly self-cutting., (© 2024 The Author(s).

Purpose: To investigate the predictive ability of individual Caries Risk Assessments (CRA) regarding oral factors supplemented with social factors in relation to caries outcome in preschool children. Furthermore, to assess various models of CRA with oral and social factors included, aiming to identify the most suitable models for different age groups., Methods: The design is a retrospective registry-based cohort study. Children visiting the dentists at ages 3 and 6 years were included. Data on oral and social factors were obtained from dental records, the Swedish Quality register for caries and periodontitis (SKaPa), and Statistics Sweden (SCB). Various models of CRA were designed, combining oral and social factors. Models were analyzed with univariable associations using simple logistic regression, and the results were presented as odds ratios (ORs). In addition, models were analyzed with area under the receiver operating characteristic (ROC) curve (AUC). Pairwise comparisons were conducted by DeLong's test, with p < 0.05 considered significant., Result: Oral factors were the most significant for caries outcome (OR 9.6), followed by social factors: foreign background (OR 4.6), low income (OR 2.83), low education of the mother (OR 2.77), single-parent family (OR 2.11), and having ≥ 3 siblings (OR 1.71), (p < 0.01). The predictive ability of CRA improved when models combining oral and social factors were used, compaired to CRA based solely on oral factors (p < 0.05). An increase of up to 15% was seen when CRA was conducted closer to the outcome., Conclusion: Models for Caries Risk Assessment including oral and social factors increase the predictive ability. Caries Risk Assessment has limited durability., (© 2024. The Author(s).)

Rationale: The benefits of improved air quality on asthma remain understudied. Objectives: Our aim was to investigate associations of changes in ambient air pollution with incident asthma from school age until young adulthood in an area with mostly low air pollution levels. Methods: Participants in the BAMSE (Swedish abbreviation for Children, Allergy, Environment, Stockholm, Epidemiology) birth cohort from Stockholm without asthma before the 8-year follow-up were included ( N  = 2,371). We estimated the association of change in individual-level air pollutant exposure (particulate matter with an aerodynamic diameter ≤ 2.5 μm [PM 2.5 ] and ≤ 10 μm [PM 10 ], black carbon [BC], and nitrogen oxides [NO x ]) from the first year of life to the 8-year follow-up with asthma incidence from the 8-year until the 24-year follow-up. Multipollutant trajectories were identified using the group-based multivariate trajectory model. We also used parametric G-computation to quantify the asthma incidence under different hypothetical interventions regarding air pollution levels. Results: Air pollution levels at residency decreased during the period, with median reductions of 5.6% for PM 2.5 , 3.1% for PM 10 , 5.9% for BC, and 26.8% for NO x . A total of 395 incident asthma cases were identified from the 8-year until the 24-year follow-up. The odds ratio for asthma was 0.89 (95% confidence interval [CI], 0.80-0.99) for each interquartile range reduction in PM 2.5 (equal to 8.1% reduction). Associations appeared less clear for PM 10 , BC, and NO x . Five multipollutant trajectories were identified; the largest reduction trajectory displayed the lowest odds of asthma (odds ratio, 0.55; 95% CI, 0.31-0.98) compared with the lowest reduction trajectory. If the PM 2.5 exposure had not declined up to the 8-year follow-up, the hypothetical asthma incidence was estimated to have been 10.9% higher (95% CI, 0.8-20.8%). Conclusions: A decrease in PM 2.5 levels during childhood was associated with a lower risk of incident asthma from school age to young adulthood in an area with relatively low air pollution levels, suggesting broad respiratory health benefits from improved air quality.

Study Objectives: We investigated the association between maternal early pregnancy body mass index (BMI) and offspring sleep apnea diagnosis., Methods: We conducted a nationwide cohort study among 3,281,803 singleton live births in Sweden born 1983-2015. Using national registers with prospectively recorded information, we followed participants for a sleep apnea diagnosis from 2 to up to 35 years of age. We compared sleep apnea risks by early pregnancy BMI categories using hazard ratios with 95% confidence intervals from adjusted Cox models. To address confounding by factors shared within families, we conducted sibling-controlled analyses and studied the relation of siblings' maternal BMI with index offspring's sleep apnea risk., Results: There were 17,830 sleep apnea diagnoses. Maternal early pregnancy BMI was positively associated with offspring sleep apnea risk; compared with women with normal BMI (18.5-24.9), adjusted hazard ratios (95% confidence intervals) of offspring sleep apnea for maternal BMI categories 25.0-29.9 (overweight), 30.0-34.9 (obesity class I), and ≥35.0 (obesity class II or III) were, respectively, 1.14 (1.09, 1.19), 1.28 (1.20, 1.36), and 1.40 (1.27, 1.54). Corresponding hazard ratios from sibling-controlled analyses representing risk change for maternal BMI differences between pregnancies were, respectively, 1.13 (1.01, 1.26), 1.17 (0.97, 1.42), and 1.32 (0.97, 1.80). Hazard ratios by siblings' maternal BMI were attenuated, suggesting a weak role for shared familial factors. Other pregnancy, birth, and neonatal complications were associated with offspring sleep apnea risk but did not substantially mediate the association with maternal obesity., Conclusions: Maternal overweight and obesity are associated with offspring sleep apnea risk in a dose-response manner., Citation: Zhu MQ, Cnattingius S, O'Brien LM, Villamor E.

Purpose: The healthcare systems in Scandinavia inform nationwide registers and the Scandinavian populations are increasingly combined in research. We aimed to compare Norway (NO), Sweden (SE), and Denmark (DK) regarding sociodemographic factors and healthcare., Methods: In this cross-sectional study, we analyzed aggregated data from the nationwide Scandinavian registers. We calculated country-specific statistics on sociodemographic factors and healthcare use (general practitioner visits, admissions to somatic hospitals, and use of medicines)., Results: In 2018, population were 5295,619 (NO), 10,120,242 (SE), and 5781,190 (DK). The populations were comparable regarding sex, age, education, and income distribution. Overall, medication use was comparable, while there was more variation in hospital admissions and general practitioner visits. For example, per 1000 inhabitants, 703 (NO), 665 (SE), and 711 (DK) individuals redeemed a prescription, whereas there were 215 (NO), 134 (SE), and 228 (DK) somatic hospital admissions per 1000 inhabitants. General practitioner contacts per 1000 inhabitants were 7082 in DK and 5773 in NO (-data from SE)., Conclusion: The Scandinavian countries are comparable regarding aggregate-level sociodemographic factors and medication use. Variations are noted in healthcare utilisation as measured by visits to general practitioners and admissions to hospitals. This variation should be considered when comparing data from the Scandinavian countries., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Objective: To assess whether the use of assisted reproductive technology (ART) therapy for conception is associated with imprinting disorders in children and the impact of parental factors related to infertility., Design: A nationwide register-based cohort study., Setting: Swedish national registers and nationwide quality IVF register., Patient(s): All liveborn singletons in Sweden (N = 2,084,127) between 1997 and 2017 with follow-up to December 31, 2018., Intervention(s): The use of specific methods implemented in ART., Main Outcome Measure(s): The International Classification of Diseases version 10 was used to identify three distinct imprinting disorder groups: Beckwith-Wiedemann syndrome (BWS), Prader-Willi syndrome (PWS), and Silver-Russell syndrome (SRS), as well as central precocious puberty. The Cox model combined with inverse probability treatment weights was used to estimate the weighted hazard ratio (wHR) with a 95% confidence interval (CI), accounting for multiple confounders., Result(s): A total of 1,044 children were diagnosed with the disorders of interest, and 52 of them were conceived using ART therapy. The overall risk of being diagnosed with any of the studied imprinting disorders was elevated in children conceived using ART therapy compared with all other children (HR, 1.84; 95% CI, 1.38-2.45). After adjusting for parental background factors, the association was partially attenuated (wHR, 1.50; 95% CI, 0.97-2.32), but remained in the weighted comparison restricted to children of couples with known infertility (wHR, 1.52; 95% CI, 1.05-2.21). For the specific diagnoses of PWS/SRS, and BWS compared with children of couples with known infertility, children conceived with ART therapy showed a small excess risk, which could not be distinguished from the null (wHR, 1.56; 95% CI, 0.93-2.62 and 1.80; 95% CI, 0.99-3.28, respectively). Further subgroup analysis showed that the combined use of intracytoplasmic sperm injection and cryopreserved embryos was associated with a higher risk of both PWS/SRS (wHR, 4.60; 95% CI, 1.72-12.28) and BWS (wHR, 6.69; 95% CI, 2.09-21.45). The number of central precocious puberty cases in children conceived using ART therapy was too small (N = 3) to make any meaningful inference., Conclusion(s): The combined use of intracytoplasmic sperm injection and cryopreserved embryos was associated with small elevated risks of PWS/SRS, and BWS in children, independent of parental factors related to infertility., Competing Interests: Declaration of Interests M.Y. reports funding from the Chinese Scholarship Council for the submitted work.

Objective - To study the correlation between P1 latency and the results of clinical language tests (Reynell III and TROG-2), the latter were used as they are recommended for follow-up assessments of children with cochlear implants (Cis) by the Swedish National Quality Register for children with hearing impairment. Design - A clinical cohort study. Study sample - Cross-sectional and consecutive sampling of 49 children with CIs coming for clinical follow-up assessment from March 2017 - December 2019. Results - For all children tested, there was a significant negative correlation (Spearman's rho= -0.403, p  = 0.011) between hearing age and P1 latency. A significant correlation between P1 latency and the Reynell III result (Spearman's rho =  -0.810, p  = 0.015) was found. In the TROG-2 group, there was no significant correlation between their P1 latency and their language test results (Spearman's rho -0.239, p  = 0.196). Conclusion - This method seems to be feasible and easily accepted. The study was conducted in a heterogeneous group of children that we meet daily in our clinic. The results indicated that P1 latency has a negative correlation with language development among our youngest patients fitted with CIs and might be a clinical tool to assess the maturation of central auditory pathways.

Introduction: Despite its increasing prevalence, the economic impact of eosinophilic esophagitis (EoE) is understudied., Methods: We estimated the societal economic burden of EoE by using real-world data from Swedish health registers., Results: Patients with EoE had 45% higher societal cost ($6,290 vs $4,349) compared with the general population, primarily driven by increased healthcare costs ($2,414 vs $1,022), which accounted for 72% of the excess societal cost in EoE., Discussion: EoE is associated with a considerable economic burden to society. With the prevalence of EoE still rising, the economic burden of EoE is expected to continue to grow., (Copyright © 2024 by The American College of Gastroenterology.)

Aims/hypothesis: To study the progression of HbA1c after diagnosis of type 1 diabetes in children and adolescents during 2010-2019 with emphasis on HbA1c nadir 3-6 months after onset., Methods: Partial funding was secured for this study. The Swedish paediatric diabetes quality register SWEDIABKIDS has >95 % coverage of type 1 diabetes up to 18 years. A mixed model for repeated measurements was used to estimate differences in HbA1c between onset year periods., Results: We followed 6,891 patients over two years from onset (48,292 HbA1c values). We found a gradual decrease in mean HbA1c 24 months after onset from 56.0 mmol/mol (7.28 %) in 2010/11 to 50.5 mmol/mol (6.77 %) in 2018/19, which is at the level of several recent intervention studies. The initial drop in HbA1c from onset until 3 and 6 months has become more pronounced in recent years. There was a significant positive correlation between HbA1c at 3 and 6 months with 12, 18 and 24 months. Percentage of severe hypoglycaemic coma was higher (5.1 % vs 3.4 %; p = 0.023) in 2010/2011 than 2018/2019, but the absolute risk of ketoacidosis was essentially unchanged, (1.5 % to 0.8 %, p = 0.110) CONCLUSIONS/INTERPRETATION: There was a continuous decrease in HbA1c over the study period 2010-2019, which coincides in time with an increased use of diabetes technology and lowering the HbA1c target to 48 mmol/mol (6.5 %). The decrease in 2-year HbA1c was preceded by a lower HbA1c nadir, which may set the trajectories for coming HbA1c and be a modifiable factor for a long-term improvement in metabolic control., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [None of the investigators have personal or financial interests in the conduct or the outcomes of the project.

Background: Offspring of parents with bipolar disorder have increased risks of their own psychopathology. However, a large-scale survey of psychiatric, somatic, and adverse social outcomes up to adulthood, which could aid in prioritizing and tailoring prevention, is lacking. It also remains to clarify how risks are modified by other parental factors., Methods: Swedish population registers were linked to compare offspring having (N = 24,788) and not having (N = 247,880) a parent with bipolar disorder with respect to psychiatric diagnoses and psychotropic medication, birth-related and somatic conditions, social outcomes, accidents, suicide attempts, and mortality. Individuals were followed until age 18. We estimated the influence of lifetime parental psychiatric comorbidity, bipolar disorder subtype, and sex on outcomes., Results: Children of parents with bipolar disorder had 2-3 times higher risks of all psychiatric diagnoses, except for bipolar disorder, for which the risk was 11-fold. Significantly increased risks were also found for several somatic conditions, low school grades, criminal behavior, victimization, accidents, and suicidal behavior. Adjusting for lifetime parental psychiatric comorbidity attenuated most associations. Offspring of a parent with bipolar disorder type 2 had statistically significantly higher risks of attention deficit hyperactivity disorder, respiratory tract conditions, and accidents compared with offspring of a parent with bipolar disorder type 1. Offspring of mothers with bipolar disorder had higher risks of several psychiatric diagnoses, respiratory tract conditions, low school grades, and accidents compared with offspring of fathers with bipolar disorder. Having two parents with bipolar disorder entailed the highest risks of psychiatric outcomes in offspring., Conclusions: Early intervention and family support are particularly warranted for the offspring of a parent with bipolar disorder in the presence of lifetime parental psychiatric comorbidity, when the parent has bipolar disorder type 2, or when the mother or both parents have bipolar disorder., (© 2024 The Authors.

Background: Centralisation of perioperative care for small children to a limited number of specialised paediatric centres has many theoretical advantages, but neither the optimal balance nor the current distribution of paediatric anaesthesia on a national scale are well elucidated. The aim of this study was to describe the distribution, adverse events, and mortality in children undergoing anaesthesia in Sweden., Methods: In this cohort study, data from all paediatric anaesthesia procedures registered in Sweden during the years 2019-22 were extracted from the Swedish Perioperative Register (SPOR). Data were analysed according to hospital level of care and ASA physical status., Results: Data from 81 hospitals were analysed. During the 4-yr period, 214,964 procedures were registered. Most procedures in neonates and infants were managed in paediatric (73%) and other university hospitals (21%). Adverse events occurred in 2.71% of cases and severe adverse events in 0.067%. The all-cause 24-h mortality rate was 6.6:10,000 anaesthetics and the all-cause 30-day mortality was 14.7:10,000 anaesthetics. The 30-day all-cause estimated mortality was highest in paediatric hospitals (95% confidence interval [CI] 30-39) compared with other university hospitals (95% CI 6.1-12), county (95% CI 1.9-4.8), district (95% CI 0.07-2.2), and smaller hospitals (95% CI 0.0-22)., Conclusions: Most procedures in neonates and infants were performed in tertiary centres, with county hospitals managing mainly older children, in accordance with national recommendations. Mortality was more common in tertiary centres, reflecting increased comorbidity and centralisation of anaesthesia of neonates and infants., (Copyright © 2024 The Author(s).

Pediatric chronic pain is common and frequently results in reduced wellbeing and functioning. Limited knowledge among health care professionals has motivated a national care program for pediatric chronic pain to increase the standard of care for this group. Emphasizing a biopsychosocial approach, treatment should focus on self-management of pain and distress to increase resilience, functioning and wellbeing. Furthermore, close collaborations between relevant stakeholders, such as families, healthcare, and school, is critical for optimal and sustained effects.

Authorities and civilians can make a report-of-concern to Social Services if they suspect a child is experiencing or witnessing violence. In 2021, Sweden implemented new legislation that considers children as victims of crime not only when abused but also when witnessing family violence, i.e., Barnfridsbrott. This study aimed to describe and analyze reports-of-concern regarding children witnessing family violence. Are there any changes in number of reports over the years? Who is reporting? And what interventions are most frequent? This is a register-based study of reports-of-concern in Gävle municipality in Sweden for the years 2018-2022. This unique register makes it possible to identify and follow up reported cases as long as they are active by Social Services. Results show there was already a major increase in the number of reports-of-concern in 2020. Most reports are made by Social Services and the police. Of all reports related to family violence, an increasing number lead to further investigations. In most of those cases, the children stay with their families, and Social Services offer counselling. Conclusion: there was a distinct increase in reports related to children witnessing family violence already starting in 2020 in the studied municipality, before the new legislation was implemented.

Background: Previously, we have reported on the efficacy and real-world effectiveness of a parent-oriented mobile health intervention (MINISTOP 1.0 and 2.0), which have shown improvements in pre-school children's lifestyle behaviours. However, there is a need for implementation evidence. The overall aims of this study are to: (i) compare two different implementation strategies for MINISTOP 3.0 (Basic vs. Enhanced) on: acceptability, appropriateness, feasibility, organizational readiness to implement MINISTOP 3.0 within Swedish child healthcare (primary outcomes) as well as reach, costs, and adoption of MINISTOP 3.0 (secondary outcomes); (ii) evaluate cost-effectiveness of MINISTOP 3.0; (iii) explore the sustainability of MINISTOP 3.0; (iv) evaluate the determinants of effectiveness of MINISTOP 3.0 on children's key lifestyle behaviours; and (v) investigate the long-term effects of MINISTOP 3.0 on children's body mass index., Methods: A hybrid type III implementation-effectiveness design will be used. A cluster randomized controlled trial will be conducted to compare the effects of basic versus enhanced implementation strategies on the outcomes at the child healthcare level. A minimum of 50 child healthcare centers across Sweden will participate and we aim to recruit 120 nurses. Child healthcare nurses in both groups will offer the MINISTOP 3.0 app to the families at the 2.5/3-year routine visit. Basic implementation strategies include educational meeting with nurses, formal implementation blueprint, develop/distribute educational materials and enhanced implementation includes all aforementioned strategies plus auditing/providing feedback and ongoing training for nurses. All outcomes will be assessed at baseline and 12 months post-implementation. Implementation outcomes will be assessed quantitatively using questionnaires and sustainability will be assessed qualitatively at 12 months. Children's key lifestyle behaviours will be collected through a parental questionnaire within the MINISTOP app at baseline and 6 months after they have received the app. Children's weight/height will be measured at routine visits at 2.5/3 (baseline), 4 and 5 years of age., Discussion: This study will provide important implementation evidence with regards to implementing mHealth interventions within Swedish child healthcare at scale and these results have the potential to be generalized to other digital interventions being implemented in child healthcare., Trial Registration: ClinicalTrials.gov, NCT05667753.

Background: Haemorrhage is a leading cause of preventable mortality in high-income countries and emergency management presents unique challenges in the prehospital setting. The study aimed to determine incidence and characteristics of fatalities from prehospital haemorrhage in Sweden., Methods: A nationwide retrospective cohort study 2012-2021 was conducted using data from the Swedish National Board of Health and Welfare. Prehospital fatality from haemorrhage was defined as a cause of death related to haemorrhage (Appendix 1) without a hospital admission on the same day. Primary outcome was age-standardized mortality rate per 100,000 inhabitants., Results: A total of 9801 prehospital fatalities from haemorrhage were identified. Annual age-standardized mortality rate decreased from 10.97 to 8.18 per 100,000 population (coefficient =  - 0.28, r 2  = 0.85, p =  < 0.001). Trauma was the most common cause (3512, 35.83%) with intentional self-harm (X60-X84), transport accidents (V01-V99) and assault (X85-Y09) being the most common mechanisms of injury. Traumatic fatalities were younger and a larger proportion were male compared to non-traumatic causes (p < 0.001). Overall median Charlson Comorbidity Index (Quan) was 0 [0-2] with a lower index noted for traumatic causes (p < 0.001). Trauma resulted in a median of 26.1 [3.65-49.22] years of life lost per patient compared to 0 [0-3.65] for non-traumatic causes (p < 0.001). Regional variations in mortality rate were observed with lower population density correlating with higher mortality rate (ρ =  - 0.64, p = 0.002)., Conclusions: Prehospital mortality from haemorrhage decreased between 2012 and 2021. Trauma was the most common cause which resulted in many years of life lost in a population with a low burden of comorbidities. There were considerable regional differences with low population density associated with higher mortality rate from prehospital haemorrhage., (© 2024. The Author(s).)
