SamenvattingDit artikel bevat een samenvatting van en achtergrondinformatie over het in 2022 verschenen kinderdeel van de nieuwe overkoepelende multidisciplinaire richtlijn rond diagnostiek, ondersteuning en zorg voor mensen met overgewicht en obesitas. Deze richtlijn, waarvan het deel over volwassenen in 2023 verschijnt, is bestemd voor alle hulp- en zorgverleners die betrokken zijn bij de ondersteuning en zorg voor mensen met obesitas of overgewicht in combinatie met risicofactoren en/of comorbiditeit, en voor degenen die zorgdragen voor de organisatie en bekostiging van de benodigde ondersteuning en zorg.De kernboodschap van het kinderdeel van de nieuwe richtlijn is in lijn met het Landelijk model ketenaanpak voor kinderen met overgewicht en obesitas uit 2018 en ook met gerelateerde richtlijnen en zorgstandaarden: het behandelaanbod dient aan te sluiten bij de wensen, behoeften en mogelijkheden van kind en gezin. Voorafgaand aan de behandeling is het daarom belangrijk om niet alleen inzicht te krijgen in (bio)medische factoren, maar ook in psychosociale factoren (kenmerken van het kind, het gezin en de context waarin zij leven) en leefstijlfactoren (voeding, bewegen en slapen).Bij de behandeling van kinderen en volwassenen is het bovendien belangrijk om een ketenaanpak/netwerkaanpak te hanteren die is ingebed in een integrale aanpak en die ook inzet op preventie gericht op een gezonde leefomgeving voor iedereen.

Little is known about the prevalence of negative weight-biased attitudes among Dutch healthcare professionals (HCPs) when treating children and adolescents with obesity and whether interdisciplinary differences are present. Accordingly, we asked Dutch HCPs that treat pediatric patients with obesity to complete a validated 22-item self-report questionnaire about their weight-biased attitudes. In total, 555 HCPs participated from seven different disciplines: 41 general practitioners (GPs), 40 pediatricians, 132 youth healthcare physicians, 223 youth healthcare nurses, 40 physiotherapists, 40 dieticians, and 39 mental health professionals. HCPs from all disciplines reported to experience negative weight-biased attitudes among themselves. Pediatricians and GPs scored highest on negative weight-biased attitudes, including frustrations in treating children with obesity, and feeling less confident and prepared to treat children with obesity. Dieticians scored the least negative weight-biased attitudes. Participants from all groups perceived weight bias expressed by their colleagues, toward children with obesity. These findings are comparable to results reported by adult HCPs from other countries. Interdisciplinary differences were found and underscore the need for more research on contributing factors that impact explicit weight bias among pediatric HCPs.

Background It is unknown whether weight class is associated with impairment of health-related quality of life (HRQOL) for children in the Netherlands. The aim of this study was to explore generic and weight-specific HRQOL in a clinical cohort of children with overweight, obesity or severe obesity aged 4–19 years in the Netherlands. Methods 803 children from three clinical cohorts participated: mean age 11.5 (SD 2.9) years, 61.1% girls. The influence of weight class was explored in a subgroup of 425 children (25.2% with overweight, 32.5% obesity and 42.3% severe obesity), of whom the exact International Obesity Task Force (IOTF) BMI class was known. Generic HRQOL was measured by the PedsQL child report. Weight-specific HRQOL was measured by the IWQOL-Kids child or parent report. Average total, subscale and item scores were reported and the influence of the IOTF BMI class analyzed by multiple linear regression, corrected for age and sex. Results Children with severe obesity had lower generic and weight-specific HRQOL scores than those with obesity or overweight. IOTF BMI class was negatively associated with item scores from all subscales, especially physical, social and emotional problems. Children with overweight reported similar HRQOL total, subscale and item scores to children with obesity.

IntroductionHealthcare professionals (HCPs) play an important role in childhood overweight and obesity care, yet they often feel ill-equipped to manage this complex and sensitive health problem. As part of Dutch integrated care for childhood overweight and obesity, a training for coordinating professionals (CPs) was designed and carried out. This study evaluates the training based on the four levels of Kirkpatrick’s model of training evaluation: (1) reaction, (2) learning, (3) behaviour, and (4) results.MethodEleven CPs who completed the training participated in this mixed-methods study. First, completed questionnaires on the four levels were analysed with Qualtrics. Next, the transcripts of semi-structured interviews on levels 1, 3 and 4 were analysed in MAXQDA using thematic analysis. ResultsOn level 1, participants were satisfied with the training as it stimulated their professional and personal development, for instance awareness of prejudices about people with overweight and obesity. Barriers, improvements and needs from the training varied between participants based on their background. On level 2, CPs improved knowledge about integrated care and its practice, skills for providing overweight and obesity care, coaching attitudes, and trust and commitment towards local integrated care. On level 3, the extent to which the learnings were practised depended on the experience and local context of the CP. Last, on level 4 CPs mentioned noticing post-training practical results for themselves, the child and the family, integrated care partners, and the participants’ organisation.Conclusion This study evaluated a training for CPs for the support and care they provide to children with overweight and obesity and their families as part of Dutch integrated care. The training contributed to improve knowledge, skills and attitudes of CPs. This study recommends sufficient implementation of local integrated care to optimally practise what was learned. More on-time evaluations of the training and taking the perspective of the organisation into account is needed. This would improve the training and give CPs confidence to adequately provide support and care to children with overweight and obesity and their families.

Limited and inconsistent evidence exists on the associations between dietary patterns and overweight during childhood. The present study describes dietary patterns of three-year-old Dutch children and associations between childhood overweight and body mass index (BMI) development between 3 and 10 years. In the GECKO Drenthe birth cohort (N = 1306), body height and weight were measured around the age of 3, 4, 5, and 10 years, and overweight was defined according to Cole and Lobstein. A validated food frequency questionnaire (FFQ) was used to measure diet at 3 years. Dietary patterns were derived using principal components analysis (PCA). Using logistic regression analyses, pattern scores were related to overweight at 3 and 10 years. A linear mixed-effect model was used to estimate BMI-SDS development between 3 to 10 years according to quartiles of adherence to the pattern scores. Two dietary patterns were identified: (1) ‘minimally processed foods’, indicating high intakes of vegetables/sauces/savory dishes, and (2) ‘ultra-processed foods’, indicating high intakes of white bread/crisps/sugary drinks. A 1 SD increase in the ‘ultra-processed foods’ pattern score increased the odds of overweight at 10 years (adjusted OR: 1.30, 95%CI: 1.08, 1.57, p = 0.006). The ‘minimally processed foods’ pattern was not associated with overweight. Although a high adherence to both dietary patterns was associated with a higher BMI-SDS up to 10 years of age, a stronger association for the ‘ultra-processed foods’ pattern was observed (p &lt, 0.001). A dietary pattern high in energy-dense and low-fiber ultra-processed foods at 3 years is associated with overweight and a high BMI-SDS later in childhood.

Background The causes and consequences of childhood obesity are complex and multifaceted. Therefore, an integrated care approach is required to address weight-related issues and improve children’s health, societal participation and quality of life. Conducting a psychosocial and lifestyle assessment is an essential part of an integrated care approach. The aim of this study was to explore the experiences, needs and wishes of healthcare professionals with respect to carrying out a psychosocial and lifestyle assessment of childhood obesity. Methods Fourteen semi-structured interviews were conducted with Dutch healthcare professionals, who are responsible for coordinating the support and care for children with obesity (coordinating professionals, ‘CPs’). The following topics were addressed in our interviews with these professionals: CPs’ experiences of both using childhood obesity assessment tools and their content, and CPs’ needs and wishes related to content, circumstances and required competences. The interviews comprised open-ended questions and were recorded and transcribed verbatim. The data was analysed using template analyses and complemented with open coding in MAXQDA. Results Most CPs experienced both developing a trusting relationship with the children and their parents, as well as establishing the right tone when engaging in weight-related conversations as important. CPs indicated that visual materials were helpful in such conversations. All CPs used a supporting assessment tool to conduct the psychosocial and lifestyle assessment but they also indicated that a more optimal tool was desirable. They recognized the need for specific attributes that helped them to carry out these assessments, namely: sufficient knowledge about the complexity of obesity; having an affinity with obesity-related issues; their experience as a CP; using conversational techniques, such as solution-focused counselling and motivational interviewing; peer-to-peer coaching; and finally, maintaining an open-minded, non-stigmatizing stance and harmonizing their attitude with that of the child and their parents. Conclusions Alongside the need for a suitable tool for conducting a psychosocial and lifestyle assessment, CPs expressed the need for requisite knowledge, skills and attitudes. Further developing a supporting assessment tool is necessary in order to facilitate CPs and thereby improve the support and care for children with obesity and their families.

Background Milk feeding type (exclusive breastfeeding [EBF], formula feeding or mixed feeding) and timing of complementary feeding (CF) have been associated with infant growth. However, studies evaluating their combined role, and the role of ethnicity, are scarce. We examined associations of feeding patterns (milk feeding type combined with timing of CF) with infant body mass index (BMI) trajectories and potential ethnic-specific associations. Methods Infant feeding and BMI data during the 1st year of life from 3524 children (Dutch n = 2880, Moroccan n = 404 and Turkish n = 240) from the Amsterdam Born Children and their Development (ABCD) cohort were used. Six feeding patterns were defined: EBF/earlyCF, EBF/lateCF (reference), formula/earlyCF, formula/lateCF, mixed/earlyCF and mixed/lateCF. A covariate adjusted latent class mixed model was applied to simultaneously model BMI trajectories and associations with feeding patterns. Potential ethnic differences in the associations were studied in a separate model where interactions between ethnicity and feeding patterns were included. Results Four distinct BMI trajectories (low, mid-low, mid-high and high) were identified. Feeding pattern of formula/earlyCF was associated with lower odds for low (OR: 0.43; 95% CI: 0.25, 0.76) or mid-high (0.28; 0.16, 0.51) (ref: high) trajectory compared with EBF/lateCF pattern (ref). An ethnic-specific model revealed that among Dutch infants, formula/earlyCF pattern was associated with lower odds for low trajectory (0.46; 0.24, 0.87), whereas among Turkish/Moroccan infants almost all feeding patterns were associated with lower odds for the low trajectory (ref: high). Conclusion Infant feeding patterns are associated with early BMI trajectories with specific ethnic differences. Future studies should take the role of ethnicity into account in the associations between infant feeding and growth.

The current study explored the preferences for and knowledge of weight-based terminology used in healthcare-related conversations, and descriptively compared the preferences of children, parents and healthcare professionals. In total, 86 children with overweight or obesity, 90 parents of children with overweight or obesity and 572 healthcare professionals indicated their preferences for 22 terms. When applicable, children and parents could indicate unfamiliarity with a term. Many children were unfamiliar with terms such as “adiposity“adipositas”” (93%), “BMI” (60%) and “morbid obesity” (53%). Children, parents and healthcare professionals disliked “fatadjective”. All groups liked the terms “healthier weight” and “above a healthy weight”. To conclude, children’s, parents’ and healthcare professionals’ preferences for weight-based terminology are predominately congruent, except for “BMI”. “BMI” is a popular term among healthcare professionals. It is recommended that healthcare professionals use terms that can be perceived as neutral or positive, such as “healthier weight”, as this may contribute to a positive conversation which may lead to better compliance, and to avoid terms that can be perceived as judgmental, such as “fatadjective”, as this may worsen the dialogue and relationship between families and healthcare professionals, and increase weight-based stigma. Healthcare professionals should be aware that children may be unfamiliar with some terms.

Background: Childhood obesity is a complex disease resulting from the interaction of multiple factors. The effective management of childhood obesity requires assessing the psychosocial and lifestyle factors that may play a role in the development and maintenance of obesity. The aim of this study was to add knowledge for further development of a psychosocial and lifestyle assessment for childhood obesity. Methods: Two methods were used. First, a scoping review (in PubMed, Embase, PsycInfo, IBSS, Scopus and Web of Science) was performed by systematically searching for scientific literature on psychosocial and lifestyle assessments for childhood obesity. Data were analysed by extracting data in Microsoft Excel. Second, focus group discussions were held with healthcare professionals from a variety of disciplines and domains to explore their experiences and views about assessing psychosocial and lifestyle factors within the Dutch integrated care approach. Data were analysed using template analyses, complemented with open coding in MAXQDA.Results: The results provide an overview of relevant psychosocial and lifestyle factors that should be assessed and were classified as child, family, parental and lifestyle (e.g. nutrition, physical activity and sleep factors) and structured into psychological and social aspects. Insights into how to assess psychosocial and lifestyle factors were identified as well, including talking about psychosocial factors, lifestyle and weight; the professional-patient relationship; and attitudes of healthcare professionals. Conclusions: This study provides an overview of psychosocial and lifestyle factors that should be identified within the context of childhood obesity care, as they may contribute to the development and maintenance of obesity. The results highlight the importance of both what is assessed and how it is assessed. The results of this study can be used to develop practical tools for facilitating healthcare professionals in conducting a psychosocial and lifestyle assessment.

Background: Many healthcare professionals (HCPs) feel uncomfortable and incompetent to talk about weight with children with overweight and obesity and their parents. To optimally target interventions that can improve obesity care for children, we assessed the self-efficacy (SE) and perceived barriers (PBs) of Dutch HCPs in regard to talking about weight and lifestyle when treating children with overweight or obesity. In addition, we analyzed interdisciplinary differences.Methods: A newly developed, practice- and literature-based questionnaire was completed by 578 HCPs of 7 different professions. Kruskal-Wallis, t-tests and chi-square tests were used to analyze interdisciplinary differences on SE, PBs and the effort to discuss weight and lifestyle despite barriers. Results: On average for the total group, the reported strength of SE was 7.2 (range 3-10; scale 1-10), and the median number of different PBs was 4.0 (range 0-12; out of 17). The majority of HCPs (94.6%) reported that they perceived one or more barriers.HCPs who perceived too many barriers to discuss the weight and lifestyle of the child in the majority of cases (9.6%), reported a lower SE (mean 6.3), as compared to professionals who were likely to discuss these topics (mean SE 7.3 p < 0.01), although a similar number of PBs. In total, 14.2% (n = 82) of all HCPs either rated their SE below 5 or reported that they did not address weight and lifestyle due to PBs in the majority of cases.Conclusions: Although on average Dutch HCPs rated their self-efficacy fairly good, for a subgroup major improvements are necessary to lower perceived barriers and improve their self-efficacy, aiming to improve the quality of care for Dutch children with obesity.

This study investigated ethnic differences in childhood body mass index (BMI) in children from Dutch and Turkish descent and the role of infant feeding factors (breastfeeding duration, milk feeding frequency, as well as the timing, frequency and variety of complementary feeding (CF)). We used data from 244 children (116 Dutch and 128 Turkish) participating in a prospective study in the Netherlands. BMI was measured at 2, 3 and 5 years and standard deviation scores (sds) were derived using WHO references. Using linear mixed regression analyses, we examined ethnic differences in BMI-sds between 2 and 5 years, and the role of infant feeding in separate models including milk or CF factors, or both (full model). Relative to Dutch children, Turkish children had higher BMI-sds at age 3 (mean difference: 0.26, 95%CI: 0.04,0.48) and 5 (0.63, 0.39,0.88), but not at 2 years (0.08, −0.16,0.31). Ethnic differences in BMI-sds were somewhat attenuated by CF factors at age 3 (0.16, −0.07,0.40) and 5 years (0.50, 0.24,0.77), whereas milk feeding had a minor impact. Of all factors, only CF variety was associated with BMI-sds in the full model. CF factors, particularly CF variety, explain a small fraction of the BMI-sds differences between Dutch and Turkish children. The role of CF variety on childhood BMI requires further investigation.

Introduction: COVID-19 lockdown measures have large impact on lifestyle behaviors and well-being of children. The aim of this mixed-methods study was to investigate the impact of COVID-19 lockdown measures on eating styles and behaviors, physical activity (PA), screen time, and health-related quality of life (HRQoL) in children (0–18 years) with severe obesity. Methods: During the first COVID-19 wave (April 2020), validated questionnaires were completed and semi-structured telephone interviews were conducted with parents of children with severe obesity (adult body mass index [BMI]-equivalent ≥35 kg/m2) and/or with the children themselves. Changes in pre-pandemic versus lockdown scores of the Dutch Eating Behavior Questionnaire Children, Pediatric Quality of Life Inventory, and Dutch PA Questionnaire were assessed. Qualitative analyses were performed according to the Grounded Theory. Results: Ninety families were approached of which 83 families were included. Characteristics of the included children were: mean age 11.2 ± 4.6 years, 52% female, mean BMI SD-score +3.8 ± 1.0. Emotional, restrained, and external eating styles, HRQoL, and (noneducational) screen time did not change on group level (all p > 0.05). However, weekly PA decreased (mean difference −1.9 h/week, p = 0.02) mostly in adolescents. In the majority of children, mean weekly PA decreased to ≤2 h/week. Children with high emotional or external eating scores during lockdown or pre-existent psychosocial problems had the lowest HRQoL (p < 0.01). Qualitative analyses revealed an increased demand for food in a significant proportion of children (n = 21), mostly in children n = 15) or improved eating behaviors (n = 11) attributed this to already existing strict eating schemes that they kept adhering to during lockdown. Conclusion: This study shows differing responses to COVID-19 lockdown measures in children with severe obesity. On group level, PA significantly decreased and in substantial minorities eating styles and HRQoL deteriorated. Children with pre-existent psychosocial problems or pre-pandemic high external or emotional eating scores were most at risk. These children and their families should be targeted by health care professionals to minimize negative physical and mental health consequences.

Summary Recent studies report negative mental health effects of the COVID‐19 related lockdown measures in general paediatric cohorts. Since obesity is a risk factor for COVID‐19 in adults, children (including adolescents) with obesity might perceive themselves to be vulnerable. Using a combined quantitative and qualitative approach, we explored COVID‐19 related anxiety in paediatric patients with severe obesity in the Netherlands using semi‐structured telephone interviews and the Paediatric Quality of Life Inventory (PedsQL) questionnaire, which had also been completed by the study population at baseline in the year prior to the COVID‐19 outbreak. In total, 75 families participated in the semi‐structured telephone interviews during the lockdown, April 2020. Characteristics of included patients were: median age 10.5 years (interquartile range = 7.6‐15.2); 52% female; mean BMI standard deviation score 3.8 (SD = 1.0). COVID‐19 related anxiety was reported for 24/75 (32%) children. The mean decrease in PedsQL score between baseline visit and COVID‐19 outbreak did not differ between children for whom anxiety was reported vs those for whom it was not (mean change −10.3 ± 36.5 vs −3.3 ± 24.4, P = .54). Self‐imposed strict quarantine measures were taken by 19/75 (25%) families. During follow‐up, several families reported that the previous contact alleviated their anxiety. In conclusion, healthcare professionals should address possible COVID‐19 related anxiety in children with severe obesity. Addressing COVID‐19 related anxiety could mitigate its potential negative effects.

Background: As in many other countries around the world, the Netherlands has a high prevalence of overweight and obesity in children. About 1 in 7 of children aged 2–19 years has either overweight or obesity. Summary: In this paper the national and local activities aimed at the prevention and management of obesity in children and adolescents in the Netherlands are reviewed. It is recommended to, nationally as well as locally, take an integrated-systems approach that tackles the obesogenic food environment as well as upstream and downstream determinants of obesity. Efforts should take a life course approach and be focused on promoting obesity prevention as well as improving the management of children who already have obesity. The national policies in the Netherlands rely heavily on self-regulation by stakeholders such as supermarkets, restaurants, and the food industry. Local policies and actions such as the whole-systems approach in Amsterdam are promising. Future directions include development of tools for the operationalization and evaluation of local systems approaches. Regulation by national and local governments is necessary to ensure a healthy food environment for children and their families, but health policies require intersectoral action. Key Messages: In the Netherlands many policies are in place or under development, especially at the municipal level (e.g., in Amsterdam), but more substantial action is urgently required.

This paper describes the design of the LIKE programme, which aims to tackle the complex problem of childhood overweight and obesity in 10&ndash, 14-year-old adolescents using a systems dynamics and participatory approach. The LIKE programme focuses on the transition period from 10-years-old to teenager and was implemented in collaboration with the Amsterdam Healthy Weight Programme (AHWP) in Amsterdam-East, the Netherlands. The aim is to develop, implement and evaluate an integrated action programme at the levels of family, school, neighbourhood, health care and city. Following the principles of Participatory Action Research (PAR), we worked with our population and societal stakeholders as co-creators. Applying a system lens, we first obtained a dynamic picture of the pre-existing systems that shape adolescents&rsquo, behaviour relating to diet, physical activity, sleep and screen use. The subsequent action programme development was dynamic and adaptive, including quick actions focusing on system elements (quick evaluating, adapting and possibly catalysing further action) and more long-term actions focusing on system goals and/or paradigm change. The programme is supported by a developmental systems evaluation and the Intervention Level Framework, supplemented with routinely collected data on weight status and health behaviour change over a period of five years. In the coming years, we will report how this approach has worked to provide a robust understanding of the programme&rsquo, s effectiveness within a complex dynamic system. In the meantime, we hope our study design serves as a source of inspiration for other public health intervention studies in complex systems.

Background: The aim of the study was to assess changes in the health-related quality of life (HRQOL) and weight status of children with overweight and obesity after participating in a 10-week family-based combined lifestyle group intervention in their community. Methods: In total, 340 children with overweight or obesity aged between 7 and 13 years, as well as one of their primary caregivers, took part in this intervention, in a real-world setting. The intervention comprised 20 group sessions for a 10-week period, and focused on improving knowledge, attitudes, social support, and self-efficacy in regard to healthy lifestyles. The Pediatric Quality of Life Inventory 4.0 (PedsQL) and Impact of Weight on Quality of Life-Kids (IWQOL-KIDS) questionnaires were used to determine generic and weight-specific HRQOL. Changes in HRQOL and BMI (standard deviation [SDS] of BMI, objectively measured) were tested using a Wilcoxon signed-rank test, Mann-Whitney U test, and paired t-test. Results: Generic quality of life (Z = -3.58, r = -0.25), weight-specific quality of life (Z = -4.83, r = -0.34), and SDS-BMI (d = 0.21) were all significantly improved after participating in the 10-week intervention. The mean attendance rate was 73.74%. Conclusion: This study demonstrated that participation in the intervention LEFF for children with overweight and obesity was associated with improved generic and weight-specific HRQOL and SDS-BMI.

PurposeThe development of a national model has led municipalities in the Netherlands to implement integrated care for childhood overweight and obesity. To monitor how this approach is being implemented locally, an appropriate tool is required. This study presents a “Tool to monitor the local implementation of Integrated Care for Childhood Overweight and obesity” (TICCO).Design/methodology/approachA three-step study was conducted in order to adapt and refine a generic integrated care questionnaire into a tool that suits the specific characteristics and context of integrated care for childhood overweight and obesity. The three consecutive steps comprised the following: a focus group session that assessed the relevance and comprehensiveness of the original integrated care instrument; a pilot questionnaire for end users that evaluated the feasibility of the preliminary tool and a pilot questionnaire that determined the feasibility and potential limitations of this adapted tool.FindingsThe adaptation process resulted in a 47-element digital tool for professionals actively involved in providing integrated care for childhood overweight and obesity. The results highlighted differences pertaining to how individual respondents judged each of the elements. These variations were found across both municipalities and different domains of integrated care.Originality/valueThis article presents an adapted tool that seeks to both support local discussion in the interpretation of individual TICCO scores and identify potential areas for improvement in local integrated care for childhood overweight and obesity.

Objective: To examine changes in generic and weight-related, health-related quality of life (HRQoL) in children and adolescents with severe obesity participating in intensive lifestyle treatment, and to examine whether changes in SDS-BMI were associated with changes in HRQoL. Methods: In this prospective observational study, a referred sample of 120 children and adolescents (8-19 years) with severe obesity (SDS-BMI ≥ 3.0, or ≥ 2.3 in combination with obesity-related comorbidity) received an intensive 1-year lifestyle treatment with an inpatient period in a specialized childhood obesity center. A weight-related (IWQOL-Kids) and three generic (KIDSCREEN-52, PedsQL 4.0, and EuroQol) HRQoL questionnaires were administered at baseline (T0), after treatment (T1), and 1 year later (T2). Generalized Linear Mixed Models and partial correlations were used to analyze changes in HRQoL and associations with changes in SDS-BMI. Results: Statistically significant improvements in generic and weight-related HRQoL overall and domain scores were observed at T1and at T2 in comparison with T0, despite partial weight regain from T1 to T2. Larger weight loss at T2 was correlated with larger improvements in physical HRQoL domains. Conclusion: Children and adolescents with severe obesity experienced long-term improvements in generic and weight-related HRQoL after participating in intensive lifestyle treatment, despite partial weight regain.

Introduction: During the COVID-19 pandemic, lockdown measures were implemented with large impact on lifestyle behaviors and well-being of children (including adolescents). The impact on children with severe obesity, who plausibly are at even larger risk, has not yet been described. Aim of this study was to investigate the impact of COVID-19 lockdown on eating behaviors, physical activity, screen time and quality of life (QoL) of children with severe obesity. Methods: In this mixed-methods study, questionnaires and semi-structured telephone interviews were used to investigate impact of COVID-19 during the first wave in the Netherlands (April 2020) on children with severe obesity (adult BMI-equivalent ≥35kg/m2) treated at our obesity center. The Dutch Eating Behavior Questionnaire - Child, Pediatric Quality of Life Inventory, and Dutch Physical Activity Questionnaire were filled out by their families pre-pandemic and during lockdown. Changes over time in percentile scores, weekly physical activity and screen time were assessed. Qualitative analyses were performed according to the Grounded Theory. Results: We included 83 families, of which 75 participated in the interviews. Their children’s characteristics were mean age 11.5years (SD 4.6), 52% female, mean BMI SD score 3.8 (SD 1.0), indicating severe obesity. On group level, no changes in scores for emotional, restrained, external eating, and QoL nor in screen time were observed (Δ scores +9.2, +3.9, +0.3; and +3.0, respectively; -0.3 hr/wk; all p>0.05). Weekly physical activity decreased (Δ -1.9 hr/wk, p=0.02). Age, pre-existent psychosocial problems and pre-pandemic questionnaire scores were associated with improved or deteriorated questionnaire scores in specific subgroups. For example, children who did not fulfill WHO physical activity criteria pre-pandemic showed a further decline from 2.8 to 0.7 h/wk (p=0.001). Children with high emotional and external eating during lockdown had the lowest QoL scores (p-values Conclusion: This study shows differential response profiles to COVID-19 lockdown in children with severe obesity. Although on group level lifestyle scores averaged out, a substantial part of families reported deterioration in physical activity and eating behaviors. Children with pre-existent psychosocial problems, high external or emotional eating scores were most at risk. Health care professionals should target these vulnerable children to minimize short- and long-term negative physical and mental health consequences.

Item does not contain fulltext The prevalence of overweight and obesity is increasing, due to, among other factors, increased availability of highly palatable food (food high in fat, salt and/or sugar). It has been proposed that certain foods and/or eating behaviours may be addictive, to a degree comparable to substances of abuse. The Yale Food Addiction Scale (YFAS) measures 'food addiction' by translating the diagnostic criteria for substance use disorder to eating behaviour. So far, only a few studies have examined the prevalence of food addiction in children with the YFAS for children (YFAS-C). Large-scale studies, especially among adolescents, are lacking. Adolescence is of particular interest because it is a period wherein unhealthy eating behaviours or addictive tendencies are likely to develop. The current study examines the prevalence of food addiction using the YFAS-C in a large group of Dutch adolescents (N = 2653) aged 14-21 years. With Generalized Estimation Equation (GEE) analysis we tested the relationship between food addiction symptoms and smoking, cannabis use, alcohol use, and sugar intake through drinks, while controlling for gender, age, educational level and weight class. In the total sample 2.6% met the criteria for a food addiction 'diagnosis', and the average symptom count was 1.0 (SD = 1.3, range 0-7). Symptoms of food addiction were positively associated with smoking, alcohol use, cannabis use and sugar intake. We propose that future studies focus on possible genetic/(neuro)biological mechanisms involved in both food addiction and substance use and that longitudinal designs are needed to examine possible causal pathways. 9 p.

BACKGROUND: Although healthcare professionals often consider body weight a sensitive and difficult topic to discuss with children, a contextualized and comprehensive understanding of youth perspectives on weight-related words used in healthcare has yet to be established. This qualitative study aims to explore perspectives of Dutch children on the terminology healthcare professionals use when discussing weight.METHODS: Fourteen interviews and one focus group discussion were held with children (age 8-16) who were in care because of their weight. A toolkit with customizable interview techniques was used in order to facilitate reflection and tailor the interview to each respondent. A narrative content analysis was conducted.RESULTS: Respondents attached both clear and subtle differences in meanings to (certain) weight-related words. Their perspectives were not unanimous for any single word. Moreover, at times, respondents framed certain words in positive or negative ways, or used a word they disliked to describe themselves. This illustrates that meanings of weight-related words are not fixed, but context and situation specific.CONCLUSION: This study revealed that meanings children assign to weight-related words are shaped by their experiences in the broader social context, especially at school, as well as with (previous) healthcare professionals. It pointed towards the importance of bedside manner, acquaintanceship, and support. Healthcare professionals treating children because of their body weight are advised to invest in a good patient-caregiver relationship, pay attention to children's previous (negative) social weight-related experiences, and reflect critically on their own preconceptions about body weight and the impact these preconceptions might have on their patient-caregiver relationships.

Many chronic non-communicable diseases are at least partly caused by unhealthy lifestyles; an example is type 2 diabetes mellitus (T2DM). Lifestyle interventions have been shown to substantially reduce the risk of T2DM in high-risk patients. The risk reduction diminishes over time, but a long-term (ten years) reduction is still achieved. Better compliance with the intervention and higher quality of lifestyle counselling during a longer period of time are predictors of improved long-term risk reduction. In patients with established T2DM, lifestyle intervention can be of great benefit as well. This can result in remission in a substantial proportion of the patients (12-46%) over a one-year period. A Mediterranean diet, which is low in both refined, starch-rich foods and high-sugar drinks, seems to result in the best outcomes. However, again the compliance and quality of lifestyle counselling are of crucial importance. Lifestyle medicine deserves serious attention in clinical practice.

A total of 120 participants (8–19 years) with an average SDS-BMI of 3.41 (SD = 0.38) was included. Measurements were conducted at baseline (T0), at the end of treatment (T12) and at the end of follow up two years after baseline (T24). The primary outcome measurement was the ΔSDS-BMI between T12 and T24. As primary determinant of weight change after treatment, the participants eating styles were evaluated with the Dutch Eating Behavior Questionnaire – child report that measures external, emotional and restraint eating. The association between outcome and determinant was assessed in linear regression analyses. Complete data were available for 76 of the 120 participants. This study shows that for girls a higher score on restraint eating at T12 and a higher score on external eating at T12 were associated with more weight (re)gain in the year after treatment. No statistically significant association with emotional eating at T12 was found. In addition for girls a higher score on external eating at T0 was associated with more weight (re)gain in the year after treatment. Furthermore, the observed changes in eating styles suggest that on average it is possible to influence these with treatment, although the detected changes were different for girls and boys and for the different eating styles. More generally, this study indicates that for girls the levels of restraint and external eating after treatment were associated with the weight change during the following year.
