Background: The objectives of this systematic review were to synthesize qualitative evidence on the impacts of COVID-19 restrictions on physical activity (PA) for children and youth, and explore factors perceived to influence those impacts. Methods: Five databases (MEDLINE, Embase, SPORTDiscus, ERIC, and CINAHL) were searched initially in June 2021 and updated in December 2021 to locate qualitative articles considering COVID-19 restrictions and PA for children and youth (≤18 y old), in any setting. Eligibility, quality assessments, and data extraction were completed by 2 independent reviewers. Data were synthesized using meta-aggregation with confidence of findings rated using ConQual. Results: After screening 3505 records, 15 studies were included. Curriculum-based PA, organized sport, and active transportation were negatively impacted by COVID-19 restrictions. Negative changes were affected by COVID-19 exposure risks, inadequate instruction, poor access, screen time, and poor weather. Unstructured PA was inconsistently impacted; outdoor unstructured PA increased for some. Positive changes were facilitated by family co-participation, availability of outdoor space, and perceived mental health benefits. Conclusion: Qualitative data indicated restrictions had a predominantly negative impact on PA for children and youth, but inconsistent impacts on unstructured PA. The improved contextual understanding offered by our review will be foundational knowledge for health strategies moving forward.

Purpose: To describe (i) nutrition policies in childcare centres, (ii) the resources and processes used to enable policy implementation, and (iii) the association between policy implementation and childcare centres’ or administrators’ characteristics. Methods: Between October 2018 and June 2019 a web-based survey that addressed nutrition policy, policy implementation, and sociodemographic characteristics was sent to eligible childcare programs (centre-based and provided meals) in the Edmonton (Alberta) metropolitan region. The survey was pretested and pilot tested. Statistical tests examined the relationship between policy implementation with centres’ and administrators’ characteristics. Results: Of 312 childcare centres that received the survey invitation, 43 completed it. The majority of centres had a nutrition policy in place (94%). On average, centres had about 9 of the 17 implementation resources and processes assessed. Most often administrators reported actively encouraging the implementation of the nutrition policy (n = 35; 87%) and least often writing evaluation reports of the implementation of the nutrition policy (n = 9; 22%). Administrator’s education level was associated with implementation total score (p = 0.009; Kruskal-Wallis). Conclusion: Most childcare centres had a nutrition policy in place, but many lacked resources and processes to enable policy implementation. Additional support is required to improve nutrition policy development and implementation.

The behavioural sciences curriculum in dental education is often fragmented and its clinical relevance is not always apparent to learners. Curriculum integration is vital to understand behavioural subjects that are interrelated but frequently delivered as separate issues in dental programmes. In this commentary, we discuss behavioural change as a curricular theme that can integrate behavioural sciences in dental programmes. Specifically, we discuss behavioural change in the context of dental education guidelines and describe four general phases of behavioural change (defining the target behaviour, identifying the behavioural determinants, applying appropriate behavioural change techniques and evaluating the behavioural intervention) to make the case for content that can be covered within this curricular theme, including its sequencing. This commentary is part of ongoing efforts to improve the behavioural sciences curriculum in dental education in order to ensure that dental students develop the behavioural competencies required for entry-level general dentists.

Enrollment of international post-secondary students is increasing across Canadian campuses. International post-secondary students may experience challenges in accessing nutritious foods that meet their dietary needs and food preferences. These challenges can pose negative impacts on their health, well-being, and academic achievement. Our aim was to describe international post-secondary students’ perceptions of (1) challenges to attaining food security and (2) consequences of food insecurity on the university experience. We conducted individual semi-structured interviews with 11 international post-secondary students who had food insecurity, were enrolled at a public university in Canada, and who had requested emergency foodhampers from the on-campus food bank. Interviews were audio-recorded, transcribed verbatim, and analyzed using manifest, inductive content analysis. International post-secondary students reported several logistical issues related to obtaining sufficient food, including a lack of time, limited family support, modest food preparation skills, and low knowledge about supportive services and resources. Students also faced challenges in sourcing culturally appropriate foods, including issues related to food availability, accessibility, acceptability, and affordability. Further, they perceived food insecurity to negatively influence their academic performance through compromised concentration, reduced class and exam attendance, and adverse mpactson physical, mental, and social well-being. Some students reported extreme food deprivation, resulting in hunger. Our results revealed the negative impacts that food insecurity can have on international post-secondary students. Findings underscore the imperative to minimize the occurrence of food insecurity while studying in Canada by introducing and enhancing support systems on campus and in the community to enable food security., Les inscriptions d’étudiants internationaux augmentent sur les campus canadiens. Les étudiants internationaux de niveau postsecondaire peuvent vivre certaines difficultés pour accéder à des aliments nutritifs qui répondent à leurs besoins et préférences alimentaires. Ces défis peuvent avoir des effets négatifs sur leur santé, leur bien-être et leurs résultats scolaires. Notre objectif était de décrire les perceptions de ces étudiants en ce qui concerne (1) les défis pour atteindre la sécurité alimentaire et (2) les conséquences de l’insécurité alimentaire sur l’expérience universitaire. Nous avons mené des entrevues individuelles semi-structurées avec 11 étudiants internationaux de niveau postsecondaire qui souffraient d’insécurité alimentaire, qui étaient inscrits dans une université publique au Canada et qui avaient demandé des paniers alimentaires d’urgence à la banque alimentaire de leur campus. Les entretiens ont été enregistrés en audio, transcrits mot pour mot, et fait l’objet d’une analyse de contenu manifeste et nductive. Les étudiants internationaux de niveau postsecondaire ont signalé plusieurs problèmes logistiques liés à l’acquisition de nourriture, notamment un manque de temps, l’absence de soutien familial, des compétences culinaires faibles et une faible connaissance des services et des ressources de soutien.Les étudiants disent également avoir été confrontés à des défis pour se procurer des aliments culturellement appropriés, y compris des problèmes liés à la disponibilité, à l’accessibilité, à l’acceptabilité et au prix des aliments. De plus, ils disent percevoir une influence négative de l’insécurité alimentaire sur leurs résultats scolaires à cause d’une concentration moindre, d’une réduction de la fréquentation des cours et des examens et des effets néfastes sur le bien-être physique, mental et social qu’elle entraîne. Certains étudiants ont signalé une privation alimentaire extrême entraînant la faim. Nos résultats ont révélé les effets négatifs que l’insécurité alimentaire pouvait avoir sur les étudiants internationaux de niveau postsecondaire.Les résultats soulignent l’impératif de minimiser l’occurrence de l’insécurité alimentaire pendant les études au Canada en introduisant des systèmes de soutien sur les campus et dans la communauté pour permettre la sécurité alimentaire et en améliorant ceux qui existent.

BACKGROUND Stakeholders can provide valuable input to improve scheduling paediatric ambulatory clinic appointments, a complex process that requires effective planning and communication between parents, administrative staff and clinicians. The purpose of our study was to characterize recommendations from parents, administrative staff and clinicians to improve paediatric ambulatory appointment scheduling. METHODS Conducted between February 2018 and January 2019, this qualitative study was guided by qualitative description. Data collection was completed using focus groups with three stakeholder groups: parents, administrative staff and clinicians. Participants provided recommendations to optimize paediatric ambulatory appointment scheduling at the Stollery Children's Hospital in Edmonton, Alberta, Canada. Focus group data were transcribed verbatim and analysed using manifest inductive content analysis. RESULTS Forty-six participants (mean age: 42.7; 87% female) participated in 12 focus groups. Parents (n = 11), administrative staff (n = 22) and clinicians (n = 13) made recommendations that were organized into two categories: appointment triaging and arranging. Triaging recommendations were related to appointment availability (e.g. providing alternatives to cancelling clinics with short notice) and waitlist management (e.g. developing clear and consistent policies regarding information flow and communication between clinics and administrative staff). Appointment arranging recommendations referred to booking (e.g. directly involving parents in the booking process), reminders (e.g. using text message reminders) and attendance (e.g. providing parents with a single point of contact who can provide the correct information about late and cancellation policies). Recommendations were similar across stakeholder groups. CONCLUSION Our findings showed congruent recommendations across stakeholder groups to address challenges with scheduling ambulatory appointments, many of which have the potential to be modified. Experimental research and quality improvement initiatives are needed to determine the feasibility, acceptability and effectiveness of stakeholder recommendations to improve triaging and scheduling paediatric ambulatory appointments.

It is recommended that primary care-based physicians refer children with overweight and obesity to multidisciplinary paediatric obesity management, which can help to improve weight and health.To determine predictors of referral to multidisciplinary paediatric obesity management.This retrospective, population-level study included physicians who could refer 2-17 years old with a body mass index ≥85th percentile to one of three multidisciplinary paediatric obesity management clinics in Alberta, Canada. Physician demographic and procedural data were obtained from Practitioner Claims and Provider Registry maintained by Alberta Health from January 2014 to December 2017. Physician characteristics were compared based on whether they did or did not refer children for obesity management. Univariable and multivariable logistic regression models analysed associations between physician characteristics and referral making.Of the 3863 physicians (3468 family physicians, 395 paediatricians; 56% male; 49.3 ± 12.2 years old; 22.3 ± 12.6 years since graduation) practicing during the study period, 1358 (35.2%) referred at least one child for multidisciplinary paediatric obesity management. Multivariable regression revealed that female physicians (versus males) [odds ratio (OR): 1.68, 95% confidence interval (CI): 1.46-1.93; P0.0001], paediatricians (versus family physicians) (OR: 4.89, 95% CI: 3.85-6.21; P0.0001) and urban-based physicians (versus non-urban-based physicians) (OR: 2.17, 95% CI: 1.79-2.65; P0.0001) were more likely to refer children for multidisciplinary paediatric obesity management.Approximately one-third of family physicians and paediatricians referred children for multidisciplinary paediatric obesity management. Strategies are needed to improve referral practices for managing paediatric obesity, especially among male physicians, family physicians and non-urban-based physicians as they were less likely to refer children.Paediatric overweight and obesity impact one-third of children in Canada and the USA. It is recommended that physicians refer children with overweight and obesity to paediatric obesity management, which can help to improve their weight and health. While referral practices of US physicians have been well characterized, Canadian evidence remains limited. To address this gap, we examined predictors of referral making for paediatric obesity management. Our study included physicians (family physicians and paediatricians) who could refer 2–17 years old with overweight and obesity to three paediatric weight management clinics in Alberta, Canada between January 2014 and December 2017. Descriptive analyses and regression models were performed. Of the 3863 physicians practicing during the study period, 1358 (35.2%) referred at least one child for paediatric obesity management. Referring physicians were more likely to be female, paediatricians and practicing in urban-based clinics. Additional research is needed to explore physicians’ decisions to refer children for obesity management, which can inform interventions to enhance referral, and ultimately, improve the health and well-being of children with obesity.

Background Accumulating evidence suggests that the metabolic effects of metformin and fermentable fibers are mediated, in part, through diverging or overlapping effects on the composition and metabolic functions of the gut microbiome. Pre-clinical animal models have established that the addition of fiber to metformin monotherapy improves glucose tolerance. However, possible synergistic effects of combination therapy (metformin plus fiber) have not been investigated in humans. Moreover, the underlying mechanisms of synergy have yet to be elucidated. The aim of this study is to compare in adolescents with obesity the metabolic effects of metformin and fermentable fibers in combination with those of metformin or fiber alone. We will also determine if therapeutic responses correlate with compositional and functional features of the gut microbiome. Methods This is a parallel three-armed, double-blinded, randomized controlled trial. Adolescents (aged 12–18 years) with obesity, insulin resistance (IR), and a family history of type 2 diabetes mellitus (T2DM) will receive either metformin (850 mg p.o. twice/day), fermentable fibers (35 g/day), or a combination of metformin plus fiber for 12 months. Participants will be seen at baseline, 3, 6, and 12 months, with a phone follow-up at 1 and 9 months. Primary and secondary outcomes will be assessed at baseline, 6, and 12 months. The primary outcome is change in IR estimated by homeostatic model assessment of IR; key secondary outcomes include changes in the Matsuda index, oral disposition index, body mass index z-score, and fat mass to fat-free mass ratio. To gain mechanistic insight, endpoints that reflect host-microbiota interactions will also be assessed: obesity-related immune, metabolic, and satiety markers; humoral metabolites; and fecal microbiota composition, short-chain fatty acids, and bile acids. Discussion This study will compare the potential metabolic benefits of fiber with those of metformin in adolescents with obesity, determine if metformin and fiber act synergistically to improve IR, and elucidate whether the metabolic benefits of metformin and fiber associate with changes in fecal microbiota composition and the output of health-related metabolites. This study will provide insight into the potential role of the gut microbiome as a target for enhancing the therapeutic efficacy of emerging treatments for T2DM prevention. Trial registration ClinicalTrials.gov NCT04578652. Registered on 8 October 2020.

This qualitative study aimed to explore the experiences of parents supporting their child with Autism Spectrum Disorder (ASD) and overweight or obesity (OW/OB), including their weight management support needs.Interview transcripts were analysed using inductive thematic analysis. Nine parents (The three themes developed were: (1) Our journey to obtain weight management support; (2) I need real-world solutions; and (3) The what, who and how of our weight management needs. Parents reported being proactive in seeking weight management support for their child but were disappointed with the services offered. Resources were not tailored to the child's complex nutrition and behavioural issues or their abilities and functioning. A multidisciplinary approach that integrated both disability and weight management expertise was desired, but not experienced. A range of formal and informal programs were recommended.This study provides a call to action for supports that ensure children with ASD and OW/OB receive integrated, individualised support to maximise their health and wellness.Implications for rehabilitationChildren with autism spectrum disorder (ASD) are at high risk of developing overweight or obesity.The weight management support needs of parents of children with ASD and overweight or obesity are not being met.Support must be tailored to the child's needs, which are often complex.Health services that integrate expertise in both disability and weight management are needed for children with ASD and their families.

Since the first national guideline for managing obesity in adults and children in Canada was published in 2007, new evidence has emerged and guideline standards have evolved. Our purpose is to describe the protocol used to update the Canadian clinical practice guideline for managing pediatric obesity.This guideline will update the pediatric components of the 2007 Canadian clinical practice guideline for the management of obesity. In partnership with Obesity Canada, we began preliminary work in 2019; activities are scheduled for completion in 2022. The guideline will follow standards developed by the National Academy of Medicine and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) working group. Guideline development will be informed by 5 complementary literature reviews: a scoping review that focuses on clinical assessment in pediatric obesity management and 4 systematic reviews to synthesize evidence regarding families' values and preferences as well as the safety and effectiveness of interventions (psychological and behavioural; pharmacotherapeutic; and surgical). We will use standard systematic review methodology, including summarizing and assessing the certainty of evidence and determining the strength of recommendations. Competing interests will be managed proactively according to recommendations from the Guidelines International Network. Diverse stakeholders, including families and clinicians, will be engaged throughout guideline development.The guideline will support Canadian families and clinicians to make informed, value-sensitive and evidence-based clinical decisions related to managing pediatric obesity. The guideline and accompanying resources for end-users will be published in English and French, and we will partner with Obesity Canada to optimize dissemination using integrated and end-of-project knowledge translation.

ObjectiveScheduling ambulatory clinic appointments includes a complex set of factors and diverse stakeholders. Families, administrative staff and clinicians may have varied experiences with scheduling clinic appointments. The objective of our study was to understand stakeholders’ perceptions and experiences with scheduling pediatric ambulatory clinic appointments.DesignGuided methodologically by qualitative description, focus groups were conducted separately with three stakeholder groups and analyzed using qualitative content analysis.SettingThis qualitative study was completed at a children’s hospital in Alberta, Canada.ParticipantsParents, administrative professionals and clinicians who used the pediatric ambulatory scheduling system regularly to elicit perceptions and experiences about issues and areas where improvements could be made.ResultsAcross 12 focus groups, parents (n = 11), administrative professionals (n = 23) and clinicians (n = 13) discussed areas for improvement related to the pediatric ambulatory scheduling system. The perceived areas for improvement were grouped into three categories regarding levels of influence: (i) ‘intrapersonal’: knowledge, skills and behaviors (e.g. insufficient training of administrative professionals); (ii) ‘interpersonal’: communication processes (e.g. parents not receiving confirmation letters); and (iii) ‘institutional’: structures and processes (e.g. varying practices and processes across clinics).ConclusionsStakeholders provided a rich description of the interrelated factors and processes that influenced the scheduling of pediatric ambulatory clinic appointments. Multilevel, experimental interventions are needed to test whether the findings described herein can enhance the structure and function of pediatric ambulatory appointment scheduling.

Purpose: To explore the selection, use, and reporting of theories, models, and frameworks (TMFs) in implementation studies that promoted healthy eating in center-based childcare. Data Source: We searched 11 databases for articles published between January 1990 and October 2018. We also conducted a hand search of studies and consulted subject matter experts. Study Inclusion and Exclusion Criteria: We included studies in center-based settings for preschoolers that addressed the development, delivery, or evaluation of interventions or implementation strategies related to healthy eating and related subjects and that explicitly used TMF. Exclusion criteria include not peer reviewed or abstracts and not in English, French, German, and Korean. Data Extraction: The first author extracted the data using extraction forms. A second reviewer verified data extraction. Data Synthesis: Direct content analysis and narrative synthesis. Results: We identified 8222 references. We retained 38 studies. Study designs included quasi-experimental, randomized controlled trials, surveys, case studies, and others. The criteria used most often for selecting TMFs were description of a change process (n = 12; 23%) or process guidance (n = 8; 15%). Theories, models, and frameworks used targeted different socioecological levels and purposes. The application of TMF constructs (e.g., factors, steps, outcomes) was reported 69% (n = 34) of times. Conclusion: Reliance on TMFs focused on individual-level, poor TMF selection, and application and reporting for the development of implementation strategies could limit TMF utility.

Pediatric obesity is a major public health issue. Lifestyle and behavioral interventions are the foundation of pediatric weight management; however, intervention effectiveness is compromised when families (children, youth, and/or parent[s]) discontinue care prematurely. Intervention attrition minimizes the potential health benefits derived from interventions, results in inefficient use of health services resources, and can magnify health disparities. Most attrition research in pediatric weight management has been descriptive, highlighting the need to advance the field, both academically and clinically. Herein, we propose a standard approach to studying attrition in pediatric weight management interventions to enhance our understanding, elevate the quality of research, enable study-to-study comparisons, and inform strategies designed to mitigate its impact. We focus on three issues. First, “Conceptualization and operationalization,” whereby the processes underlying attrition from interventions should be decomposed into clinically important phases that are defined based on intervention characteristics. Relatedly, theoretically relevant variables should be identified with different mechanisms driving attrition in each phase. We propose a matrix of attrition, a tool designed to delineate the relevant stages of attrition and associated variables of analytical value. Second, “Pre-study” underscores the value of developing a plan to study attrition a priori rather than post hoc, including variable and sample size considerations, which broadens the range and quality of analysis. Finally, “Post-study” emphasizes comprehensive reporting of attrition, outlines typical comparisons of analytical interest, and statistical techniques used to handle missing data. Implications for clinical practice in pediatric weight management are discussed. Clinical Trial Registration: Not applicable.

Our study purpose was to determine the prevalence of metabolically healthy obesity (MHO) and examine factors associated with MHO in children with obesity. This cross-sectional study was a secondary, exploratory analysis of data that included 2-17 years old with a body mass index (BMI) ≥85th percentile from the CANadian Pediatric Weight management Registry. Children were classified as having MHO or metabolically unhealthy obesity (MUO) using consensus-based criteria. Those with MHO had normal triglycerides, high-density lipoprotein cholesterol, blood pressure, and fasting glucose. Logistic regression was used to examine factors associated with MHO, which included calculating odds ratios (ORs) and 95% confidence intervals (CIs). In total, 945 children were included (mean age: 12.3 years; 51% female). The prevalence of MHO was 31% (n = 297), with lower levels across increasing age categories (2-5 years [n = 18; 43%], 6-11 years [n = 127; 35%], 12-17 years [n = 152; 28%]). Children with MHO were younger, weighed less, and had lower BMI z-scores than their peers with MUO (all p

Background This study aimed to use implicit retraining to change automatic associations between body size and physical activity (PA) in women with obesity to reduce weight bias internalisation (WBI). Methods A Solomon-square experimental design was used to determine the effect of a four-week online implicit retraining intervention on WBI (primary measure) and PA attitudes, self-efficacy, and self-reported behaviour (secondary measures). The intervention was a visual probe task pairing counter-stereotypical images of active individuals with obesity with positive PA-related words. In qualitative telephone interviews, a sub-sample of participants provided feedback and recommendations for using counter-stereotypical images in PA promotion. Results Women completed the intervention (n = 48) or a control task (n = 55). Results of a RM-ANOVA showed no interaction or main effect of group on WBI. A main effect of time demonstrated that both groups had reduced WBI between pre-test and post-test, through to one-week follow-up. There were no differences between groups or over time for PA attitudes, self-efficacy, or behaviour. Women who completed interviews (n = 16) discussed several benefits and drawbacks of using counter-stereotypical images. Conclusion Implicit retraining did not reduce WBI but qualitative findings support the use of counter-stereotypical PA images.

Summary Background Disease severity in paediatric obesity is usually defined using the body-mass index (BMI). Although informative at the population level, its usefulness on an individual level has limitations. The use of a clinical staging system—Edmonton Obesity Staging System for Pediatrics (EOSS-P)—in identifying health risk has been proposed. This study aimed to examine the association between BMI class and EOSS-P stage. Methods This cross-sectional study was done in children with obesity aged 5–17 years who enrolled in the Canadian Pediatric Weight Management Registry (CANPWR) between May 31, 2013, and Oct 27, 2017, involving ten multidisciplinary paediatric weight management clinics in Canada. We classified participants into WHO BMI classes (class I as 2–3 SD scores, class II as >3 SD scores, and class III as >4 SD scores above the WHO growth standard median), and applied the EOSS-P staging system (stages 0, 1, and 2/3) based on the clinical assessment of coexisting metabolic, mechanical, mental health, and social milieu issues. Clinical information was extracted from medical records and reported using standardised case report forms. Associations of BMI class with EOSS-P stage were examined in children with complete data. Findings Of the 847 children with complete data, 546 (64%) had severe obesity based on BMI class (ie, class II or III) and 678 (80%) were EOSS-P stage 2/3. Stage 2/3 obesity-related health issues were common; mental health concerns were most common (520 [61%] of 847 children), followed by metabolic (349 [41%] of 847 children), social milieu (179 [21%] of 847 children), and mechanical (86 [10%] of 847 children) health issues. Mental health issues (eg, anxiety and attention-deficit hyperactivity disorder) were equally distributed across BMI classes, metabolic health issues were slightly more common in higher BMI classes, and mechanical (eg, musculoskeletal issues and sleep apnoea) and social milieu (eg, bullying and low household income) issues increased with increasing BMI class. Of children with class I obesity, 206 (76%) of 270 had overall EOSS-P stage 2/3, compared with 195 (85%) of 229 with class III obesity. Interpretation Physical and mental health issues were highly prevalent among children with obesity irrespective of BMI class. Participants with class III obesity carried the greatest health risk across subcategories of the EOSS-P. As BMI class increased, a concomitant increased disease burden in mechanical and social milieu issues was observed, whereas metabolic and mental health risks were high across BMI classes.

Paediatric obesity management remains generalised to dietary and exercise modifications with an underappreciation for the contributions of eating behaviours and appetitive traits in the development of obesity. To determine whether treatment-seeking children and adolescents with obesity cluster into phenotypes based on known eating behaviours and appetitive traits (“eating correlates”) and how socio-demographic and clinical characteristics associate with different phenotypes. A cross-sectional, multi-centre questionnaire was administered between November 2015 and March 2017 examining correlates of eating in children and adolescents attending weight-management programmes in Canada. Latent profile analysis was used to cluster participants based on seven eating correlate scores obtained from questionnaires. Analysis of variance (ANOVA) was used to determine phenotype differences on socio-demographic and clinical characteristics. Multinomial logistic regression models assessed relative risk of specific characteristics associating with a disordered eating phenotype. Participants were 247 children and adolescents (45.3% male, mean BMI z-score = 3.4 ± 1.0 kg/m2) from six paediatric weight management centres in Canada. Seven eating correlates clustered into three distinct phenotypes: (1) loss of control eating, emotional eating, external eating, hyperphagia, impulsivity (“Mixed-Severe”; n = 42, 17%), (2) loss of control eating, emotional eating, external eating, hyperphagia (“Mixed-Moderate”; n = 138, 55.9%), and (3) impulsivity (“Impulsive”; n = 67; 27.1%). Social functioning scores and body esteem were significantly different across groups, with the Mixed-Severe participants having the poorest social functioning and lowest body esteem. Low body esteem indicated a greater risk of being in a multi-correlate group compared to the Impulsive group, while poor social function had a greater risk of clustering in the Mixed-Severe than Impulsive phenotype. Distinct eating phenotypes were found in treatment-seeking children and adolescents with obesity. Empirical evidence is needed, but these data suggest that tailored treatment approaches could be informed by these classifications to improve weight-management outcomes.

Background: Clinical practice guidelines for pediatric weight management highlight the importance of family-based behavioral strategies to enhance health behaviors. Little is known, however, of how clinics implement these programs. The study objectives were to (1) describe how Canadian pediatric weight management clinics deliver care and (2) evaluate change in services over time. Methods: The CANadian Pediatric Weight management Registry (CANPWR) is a multisite prospective cohort study of participants enrolled in a Canadian pediatric weight management clinic. Clinical program characteristics (e.g., referral process, inclusion criteria, funding, program characteristics, patient interaction methods, and follow-up) were collected at the start and end of the CANPWR recruitment period (2015-2019). Results: Entrance into the nine clinics varied with limiting criteria based on geographic proximity, age, weight status, and presence of health conditions. The clinics varied in size (50-220 new patients/year). The planned length of intervention varied widely, from 10 weeks to open-ended (median 2 years). Behavior modification strategies were delivered with a mix of individual and group-based sessions and most were delivered in person, complemented by use of virtual care. Over time, more clinics saw patients under the age of 5 years and all clinics defined a program length. Conclusion: Although all clinics offered family-based behavioral weight management services, these varied considerably, especially in program entrance criteria, size of clinic, and the length of intervention. The influence of the variability in delivery of services on health outcomes will be addressed in future studies.

Background: The purpose of this study was to evaluate the effectiveness of a 10-week blended family-based childhood obesity management program, relative to a wait-list control, in improving child b...

INTRODUCTION Cardiovascular disease (CVD) originates in childhood and risk is exacerbated in obesity. Mechanisms of the etiologic link between early adiposity and CVD-risk remain unclear. Postprandial or non-fasting dyslipidemia is characterized by elevated plasma triglycerides (TG) and intestinal-apolipoprotein(apo)B48-remnants following a high-fat meal and is a known CVD-risk factor in adults. The aim of this study was to determine (a) whether the fasting concentration of apoB48-remnants can predict impaired non-fasting apoB48-lipoprotein metabolism (fat intolerance) and (b) the relationship of these biomarkers with cardiometabolic risk factors in youth with or without obesity. METHODS We assessed fasting and non-fasting lipids in youth without obesity (n = 22, 10 males, 12 females) and youth with obesity (n = 13, 5 males, 8 females) with a mean BMI Z-score of 0.19 ± 0.70 and 2.25 ± 0.31 (P = .04), respectively. RESULTS Fasting and non-fasting apoB48-remnants were elevated in youth with obesity compared to youth without obesity (apoB48: 18.04 ± 1.96 vs 8.09 ± 0.59, P

OBJECTIVE To conduct a systematic review of the literature for strategies designed to reduce attrition in managing paediatric obesity. METHODS We searched Ovid Medline (1946 to May 6, 2020), Ovid Embase (1974 to May 6, 2020), EBSCO CINAHL (inception to May 6, 2020), Elsevier Scopus (inception to April 14, 2020), and ProQuest Dissertations & Theses (inception to April 14, 2020). Reports were eligible if they included any obesity management intervention, included 2 to 18 year olds with overweight or obesity (or if the mean age of participants fell within this age range), were in English, included experimental study designs, and had attrition reduction as a main outcome. Two team members screened studies, abstracted data, and appraised study quality. RESULTS Our search yielded 5,415 original reports; six met inclusion criteria. In three studies, orientation sessions (n = 2) and motivational interviewing (MI) (n = 1) were used as attrition-reduction strategies before treatment enrollment; in three others, text messaging (n = 2) and MI (n = 1) supplemented existing obesity management interventions. Attrition-reduction strategies led to decreased attrition in two studies, increased in one, and no difference in three. For the two strategies that reduced attrition, (a) pre-treatment orientation and (b) text messaging between children and intervention providers were beneficial. The quality of the six included studies varied (good [n = 4]; poor [n = 2]). CONCLUSION Some evidence suggests that attrition can be reduced. The heterogeneity of approaches applied and small number of studies included highlight the need for well-designed, experimental research to test the efficacy and effectiveness of strategies to reduce attrition in managing paediatric obesity.

Background Clinical practice guidelines (CPGs) include evidence-based recommendations for managing obesity in adolescents. However, information on how health care providers (HCPs) implement these recommendations in day-to-day practice is limited. Our objectives were to explore how HCPs deliver weight management health services to adolescents with obesity and describe the extent to which their reported practices align with recent CPGs for managing pediatric obesity. Methods From July 2017 to January 2018, we conducted a qualitative study that used purposeful sampling to recruit HCPs with experience in adolescent weight management from multidisciplinary, pediatric weight management clinics in Edmonton and Ottawa, Canada. Data were collected using audio-recorded focus groups (4–6 participants/group; 60–90 min in length). We applied inductive, semantic thematic analysis and the congruent methodological approach to analyze our data, which included transcripts, field notes, and memos. Qualitative data were compared to recent CPGs for pediatric obesity that were published by the Endocrine Society in 2017. Of the 12 obesity ‘treatment-related’ recommendations, four were directly relevant to the current study. Results Data were collected through three focus groups with 16 HCPs (n = 10 Edmonton; n = 6 Ottawa; 94% female; 100% Caucasian), including dietitians, exercise specialists, nurses, pediatricians, psychologists, and social workers. We identified three main themes that we later compared with CPG recommendations, including: (i) discuss realistic expectations regarding weight management (e.g., shift focus from weight to health; explore family cohesiveness; foster delayed vs instant gratification), (ii) personalize weight management (e.g., address personal barriers to change; consider developmental readiness), and (iii) exhibit non-biased attitudes and practices (e.g., de-emphasize individual causes of obesity; avoid making assumptions about lifestyle behaviors based on weight). Based on these qualitative findings, HCPs applied all four CPG recommendations in their practices. Conclusions HCPs provided practical insights into what and how they delivered weight management for adolescents, which included operationalizing relevant CPG recommendations in their practices.

OBJECTIVES (1) To explore individual and family characteristics related to anthropometric and cardiometabolic health indicators and (2) examine whether characteristics that correlate with cardiometabolic health indicators differ across severity of obesity at time of entry to Canadian pediatric weight management clinics. METHODS We conducted a cross-sectional analysis of 2-17 year olds with overweight or obesity who registered in the CANadian Pediatric Weight Management Registry (CANPWR) between May 2013 and October 2017 prior to their first clinic visit. Individual modifiable health behaviors included dietary intake, physical activity, screen time, and sleep. Family characteristics included parental BMI, family medical history, socioeconomic status and family structure. Linear mixed effects stepwise regression analysis was performed to determine which characteristics were related to each health indicator: BMI z-score; waist circumference; waist to height ratio; blood pressure; glycemia; HDL cholesterol; non-HDL cholesterol; triglycerides. RESULTS This study included 1296 children (mean age ± standard deviation: 12.1 ± 3.5 years; BMI z-score: 3.55 ± 1.29; 95.3% with obesity). Hours spent sleeping (estimated β = -0.10; 95% CI [-0.15, -0.05], p = 0.0001), hours per week of organized physical activity (estimated β = -0.32; 95% CI [-0.53, -0.11], p = 0.0026), daily sugared drink intake (estimated β = 0.06; 95% CI [0.01, 0.10], p = 0.0136) and maternal BMI (estimated β = 0.03; 95% CI [0.02, 0.04], p

Objective To determine the relative effectiveness of dietary macronutrient patterns and popular named diet programmes for weight loss and cardiovascular risk factor improvement among adults who are overweight or obese. Design Systematic review and network meta-analysis of randomised trials. Data sources Medline, Embase, CINAHL, AMED, and CENTRAL from database inception until September 2018, reference lists of eligible trials, and related reviews. Study selection Randomised trials that enrolled adults (≥18 years) who were overweight (body mass index 25-29) or obese (≥30) to a popular named diet or an alternative diet. Outcomes and measures Change in body weight, low density lipoprotein (LDL) cholesterol, high density lipoprotein (HDL) cholesterol, systolic blood pressure, diastolic blood pressure, and C reactive protein at the six and 12 month follow-up. Review methods Two reviewers independently extracted data on study participants, interventions, and outcomes and assessed risk of bias, and the certainty of evidence using the GRADE (grading of recommendations, assessment, development, and evaluation) approach. A bayesian framework informed a series of random effects network meta-analyses to estimate the relative effectiveness of the diets. Results 121 eligible trials with 21 942 patients were included and reported on 14 named diets and three control diets. Compared with usual diet, low carbohydrate and low fat diets had a similar effect at six months on weight loss (4.63 v 4.37 kg, both moderate certainty) and reduction in systolic blood pressure (5.14 mm Hg, moderate certainty v 5.05 mm Hg, low certainty) and diastolic blood pressure (3.21 v 2.85 mm Hg, both low certainty). Moderate macronutrient diets resulted in slightly less weight loss and blood pressure reductions. Low carbohydrate diets had less effect than low fat diets and moderate macronutrient diets on reduction in LDL cholesterol (1.01 mg/dL, low certainty v 7.08 mg/dL, moderate certainty v 5.22 mg/dL, moderate certainty, respectively) but an increase in HDL cholesterol (2.31 mg/dL, low certainty), whereas low fat (−1.88 mg/dL, moderate certainty) and moderate macronutrient (−0.89 mg/dL, moderate certainty) did not. Among popular named diets, those with the largest effect on weight reduction and blood pressure in comparison with usual diet were Atkins (weight 5.5 kg, systolic blood pressure 5.1 mm Hg, diastolic blood pressure 3.3 mm Hg), DASH (3.6 kg, 4.7 mm Hg, 2.9 mm Hg, respectively), and Zone (4.1 kg, 3.5 mm Hg, 2.3 mm Hg, respectively) at six months (all moderate certainty). No diets significantly improved levels of HDL cholesterol or C reactive protein at six months. Overall, weight loss diminished at 12 months among all macronutrient patterns and popular named diets, while the benefits for cardiovascular risk factors of all interventions, except the Mediterranean diet, essentially disappeared. Conclusions Moderate certainty evidence shows that most macronutrient diets, over six months, result in modest weight loss and substantial improvements in cardiovascular risk factors, particularly blood pressure. At 12 months the effects on weight reduction and improvements in cardiovascular risk factors largely disappear. Systematic review registration PROSPERO CRD42015027929.

Background The prevalence of overweight and obesity remains high in Canada, and the current standard for the treatment of childhood obesity is in-person, family-based, multidisciplinary interventions that target lifestyle behaviors (e.g., diet, physical activity, and sedentary behaviors). These programs are costly to operate, have limited success, and report recruitment and retention challenges. With recent advances in technology, mobile health or mHealth has been presented as a viable alternative to in-person interventions for behavior change, especially with teens. Purpose The primary aim of this study is to test the efficacy of Aim2Be, a gamified app based on behavior change theory with health coaching to improve weight outcomes (i.e., decrease in standardized body mass index (zBMI)) and lifestyle behaviors (i.e., improve dietary quality, increase fruit and vegetable intake, reduce sugar-sweetened beverage intake, increase physical activity, and reduce screen time) among children 10- to 17-years old with overweight or obesity versus their peers randomized into a waitlist control condition. The secondary aims of this study are to 1) test whether supplementing the Aim2Be program with health coaching increases adherence and 2) examine the mediators and moderators of adherence to the Aim2Be intervention. Methods We will employ a randomized controlled trial design and recruit 200 child and parent dyads to participate in the study (2019–2020). Participants will be recruited from Canadian pediatric weight management clinics and through online advertisements. Child participants must be between the ages of 10 and 17 years, have overweight or obesity, be able to read English at least at a grade 5 level, and have a mobile phone or home computer with internet access. Following baseline data collection, participants will be randomized into intervention and waitlist control groups. Intervention participants will receive access to Aim2Be, with access to health coaching. After having their data collected for 3 months, the control group will gain access to Aim2Be, with no access to health coaching. Participants will control their frequency and duration of app usage to promote autonomy. Discussion Findings from this study will determine the efficacy of using Aim2Be in improving child weight outcomes and lifestyle behaviors and guide future mHealth interventions for pediatric weight management.

Childcare settings are ideal for health promotion; however, they may not provide food environments that support children's healthy eating behaviours. To address this problem, researchers and practitioners have designed interventions with the aid of Theories, Models and Frameworks (TMFs) with the aim to improve centre-based childcare food environments. Considering the many TMFs that exist, the question of which TMF to select remains a challenge. As such, one of the objectives of our scoping review was to explore the selection criteria used in studies that aimed to promote healthy eating in centre-based childcare.We utilized the scoping review steps outlined by Arksey & O'Malley (2005), and Levac, Colquhoun, & O'Brien (2012). We searched Medline, Embase, CINAHL, ERIC, PsycINFO, Scopus, CAB Abstracts, Agricola, ProQuest Dissertations and Theses, Prospero, and Cochrane library of SR for studies published from January 1990 to October 2018. We also consulted subject matter experts and hand searched reference lists. First level screening was completed by two reviewers (Kappa > 0.8). Second level was completed by one reviewer and questions were addressed through discussion with a second reviewer. TMF categorisation (i.e., individual, community, process and evaluation-focused) was informed by Nilsen (2015) and Rimer (2005). We used direct content analysis to organize the reported criteria used by authors to select TMFs. The rationales presented by authors were coded using Birken et al. (2017) criteria and definitions, which were based on seminal articles and an iterative consensus process. The categorization was completed by one reviewer (MV) and verified by a second reviewer (AF).We retained 38 studies and identified 28 TMFs. TMFs were used to design implementation strategies, steps and outcomes, identify implementation factors and stakeholders, explain findings, and provide recommendations. Of the total of 14 criteria for selecting TMFs identified, the most frequently used were for describing a change process (n = 12; 23%), providing process guidance (n = 8; 15%), and TMFs use in empirical studies (n = 7; 13%).TMF selection was most often based on descriptive rather than predictive or explanatory characteristics. Increasing childcare researchers’ and practitioners’ awareness of existing TMFs and tools to guide TMF selection might reduce selection based on convenience or where limited evidence for TMF effectiveness exist.

Objectives To characterize the children who were referred, determine the proportion of referred children who enrolled, and examine factors associated with enrollment in multidisciplinary clinical care for pediatric weight management. Study design This cross-sectional study included the population of children (2-17 years of age; body mass index of ≥85th percentile) referred to 1 of 3 hospital-based multidisciplinary weight management clinics in Alberta, Canada, from April 2013 to April 2016. Referral and enrollment data were obtained from Alberta Health Services databases. Bivariate and multivariable logistic regression models were used to determine the independent and combined effects of predictors of enrollment. Results Of the 2014 children (51.8% male; mean body mass index z-score: 3.42 ± 0.03) referred to multidisciplinary clinical care, 757 (37.6%) enrolled in care. Most referred children had severe obesity and were referred by physicians. Several factors independently predicted enrollment; however, in our most parsimonious multivariable model, only the time gap (OR, 0.94; 95% CI, 0.88-0.99; P = .03) between the attendance date of the orientation session and the booking date of initial appointment predicted enrollment for all children. Body mass index z-score (OR, 0.81; 95% CI, 0.67-0.98; P = .03) and time gap (OR, 0.92; 95% CI, 0.85-0.99; P = .02) predicted enrollment in children with severe obesity exclusively. Conclusions Fewer than 40% of referred children enrolled in multidisciplinary clinical care. Reducing the duration of enrollment and providing additional support for treatment initiation to children with severe obesity may enhance treatment uptake for pediatric weight management.

BackgroundAdolescents and providers can benefit from practical tools targeting lifestyle modification for obesity prevention and management. We createdConversation Cards for Adolescents©(CCAs), a patient-centered communication and behavior change tool for adolescents and providers to use in clinical practice. The purpose of our study is to (i) assess the feasibility of CCAs in a real-world, practice setting to inform full-scale trial procedures, (ii) assess user experiences of CCAs, and (iii) determine the preliminary effect of CCAs on changing behavioral and affective-cognitive outcomes among adolescents.MethodsStarting in early 2019, this prospective study is a nested mixed-methods, theory-driven, and pragmatic pilot randomized controlled trial with a goal to enroll 50 adolescents (13–17 years old) and 9 physicians practicing at the Northeast Community Health Centre in Edmonton, Alberta, Canada. Adolescents will collaboratively set one S.M.A.R.T. (specific, measurable, attainable, realistic, timely) goal with their physician to implement over a 3-week period; however, only those randomized to the experimental group will use CCAs to inform their goal. Outcome assessments at baseline and follow-up (3 weeks post-baseline) will include behavioral, affective-cognitive, and process-related outcomes.DiscussionIn examining the feasibility, user experiences, and preliminary effect of CCAs, our study will add contributions to the obesity literature on lifestyle modifications among adolescents in a real-world, practice setting as well as inform the scalability of our approach for a full-scale effectiveness randomized controlled trial on behavior change.Trial registrationClinicalTrials.gov Identifier:NCT03821896.

We conducted a scoping review to identify definitions of metabolically healthy obesity (MHO), describe gaps in the literature, and establish a universal definition of MHO in children. We searched electronic databases from January 1980 to June 2017 and grey literature. Experimental, quasi-experimental, or observational studies were eligible for inclusion if they (i) included a definition of MHO that identified risk factors, cut-off values, and the number of criteria used to define MHO, and (ii) classified 2-18 year olds as overweight or obese. Two reviewers independently screened 1,711 papers for relevance and quality; we extracted data from 39 individual reports that met inclusion criteria. Most (31/39; 79%) definitions of MHO included an absence of cardiometabolic risk factors. Heterogeneity across MHO definitions, obesity criteria, and sample sizes/characteristics resulted in variable prevalence estimates (3-80%). Finally, we convened an international panel of 46 experts to complete a 4-round Delphi process to generate a consensus-based definition of MHO. Based on consensus (≥ 80% agreement), our definition of MHO included: high density lipoprotein-cholesterol > 40 mg/dl (or > 1.03 mmol/l), triglycerides ≤ 150 mg/dl (or ≤ 1.7 mmol/l), systolic and diastolic blood pressure ≤ 90th percentile, and a measure of glycemia. This definition of MHO holds potential universal value to enable comparisons between studies and inform clinical decision-making for children with obesity.

PurposeThe purpose of this paper is to conduct a narrative review of the food insecurity literature pertaining to university and college students studying in Very High Human Development Index countries. It aims to document food insecurity prevalence, risk factors for and consequences of food insecurity and food insecurity coping strategies among students.Design/methodology/approachEnglish articles published between January 2000 and November 2017 were identified using electronic databases. Quality Assessment Tool for Quantitative Studies assessed the study quality of quantitative research.FindingsA total of 37 quantitative, three mixed-methods and three qualitative studies were included from 80,914 students from the USA (n=30 studies), Australia (n=4), Canada (n=8) and Poland (n=1). Prevalence estimates of food insecurity were 9–89 percent. All quantitative studies were rated weak based on the quality assessment. Risk factors for food insecurity included being low income, living away from home or being an ethnic minority. Negative consequences of food insecurity were reported, including reduced academic performance and poor diet quality. Strategies to mitigate food insecurity were numerous, including accessing food charities, buying cheaper food and borrowing resources from friends or relatives.Research limitations/implicationsGiven the heterogeneity across studies, a precise estimate of the prevalence of food insecurity in postsecondary students is unknown.Practical implicationsFor many students studying in wealthy countries, obtaining a postsecondary education might mean enduring years of food insecurity and consequently, suffering a range of negative academic, nutritional and health outcomes. There is a need to quantify the magnitude of food insecurity in postsecondary students, to inform the development, implementation and evaluation of strategies to reduce the impact of food insecurity on campus.Originality/valueThis review brings together the existing literature on food insecurity among postsecondary students studying in wealthy countries to allow a better understanding of the condition in this understudied group.

Background: Health care professionals play a critical role in preventing and managing childhood obesity, but the American Academy of Pediatrics recently stressed the importance of using sensitive and nonstigmatizing language when discussing weight with children and families. Although barriers to weight‐related discussions are well known, there are few evidence‐based recommendations around communication best practices. Disability populations in particular have previously been excluded from work in this area. The objectives were to present the findings of a recent scoping review to children with and without disabilities and their caregivers for their reactions; and to explore the experiences and perceptions of the children and their caregivers regarding weight‐related communication best practices. Methods: Focus group and individual interviews were conducted with 7–18‐year olds with and without disabilities and their caregivers. The interview guide was created using findings from a recent scoping review of weight‐related communication best practices. Inductive thematic analysis was employed. Results: Eighteen children (9 boys; 7 children with disabilities) and 21 caregivers (17 mothers, 1 step‐father, 3 other caregivers) participated in 8 focus group and 7 individual interviews. Preferred communication strategies were similar across those with and without disabilities, although caregivers of children with autism spectrum disorder endorsed more concrete approaches. Discussions emphasizing growth and health were preferred over weight and size. Strengths‐based, solution‐focused approaches for weight conversations were endorsed, although had not been widely experienced. Conclusion: Perceptions of weight‐related communication were similar across stakeholder groups, regardless of children's disability or weight status. Participants generally agreed with the scoping review recommendations, suggesting that they apply broadly across different settings and populations; however, tailoring them to specific circumstances is critical. Empirical evaluations are still required to examine the influence of weight‐related communication on clinically important outcomes, including behaviour change and family engagement in care.

OBJECTIVES: To examine children’s wait time to access a multidisciplinary, tertiary-level weight management clinic and assess anthropometric changes from time of referral to baseline assessment. METHOD: A retrospective medical record review was completed of children (5 to 17 years) enrolled in a multidisciplinary, tertiary-level paediatric weight management clinic from 2006 to 2015. Children’s demographic and anthropometric data from their referral to and baseline assessment at the clinic were retrieved from medical records. Based on changes in body mass index (BMI) z-score from the time of referral to baseline assessment, children were categorized as decreasers (>0.05 unit decrease), increasers (>0.05 unit increase) or stabilizers (−0.05 to 0.05 unit change). The proportion of children with a ≥0.25 unit BMI z-score reduction was calculated. Analysis of variance and chi-squared tests were performed. RESULTS: Children (n=400) were 11.7 ± 2.9 years old at the time of referral, 52.8% (n=211) female, and had an average wait time of 4.5 ± 3.9 months. By 3 and 6 months postreferral, 44.0% (n=176) and 80.8% (n=323), respectively, had attended baseline assessments. Based on BMI z-score change, children were classified as decreasers (n=183; 45.8%), increasers (n=118; 29.5%) or stabilizers (n=99; 24.8%). One-fifth of children (n=86; 21.5%) experienced a BMI z-score reduction ≥0.25 units, a subgroup that was younger, had a higher BMI z-score at referral, and had a longer wait time between referral and baseline assessment (all P

Objective To explore parents' recommendations to enhance enrollment in multidisciplinary clinical care for managing pediatric obesity. Study design Data for this interpretative description study were collected through individual, semistructured interviews that were audiorecorded, transcribed verbatim, and analyzed thematically. Parents (n = 79) were recruited from 4 multidisciplinary weight management clinics in Canada located in Edmonton, Hamilton, Montreal, and Vancouver. Results Most interviewed parents had children with obesity (body mass index ≥95th percentile; 84.2%), were female (87.3%), had postsecondary education (69.6%), and were white (75.9%). Parents' recommendations referred to enrollment opportunities, information about obesity services, motivation for treatment, and accessibility to obesity services. Specifically, parents recommended to increase referral options and follow-up contacts with families during the enrollment process, inform referring physicians and families about the availability and characteristics of obesity services, enhance families' motivation for treatment, prevent families from getting discouraged, make services more appealing to families, and address accessibility issues (eg, offering multiple options for appointment times, providing support for transportation). Conclusions Parents' recommendations support the need for family-centered approaches to enhance enrollment; however, their feasibility, acceptability, and effectiveness remain to be tested empirically.

Summary Healthy lifestyle behaviours are key to successful weight management, but have proven to be challenging to attain for adolescents with obesity. The purpose of our scoping review was to (i) describe barriers and enablers that adolescents with obesity encounter for healthy nutrition, physical activity, sedentary behaviour and sleep habits and (ii) identify gaps in the literature. We adhered to established methodology for scoping reviews. Six databases were searched (1980–June 2016) for original articles published in English or French that focused on lifestyle behaviours of 13- to 17-year-olds in paediatric weight management. Following screening and data extraction, findings of selected articles were synthesized thematically using a social ecological framework. Stakeholder consultation (n = 20) with adolescents with obesity and health professionals was completed to enhance methodological rigour. Our search yielded 17 articles for inclusion, including 546 unique participants. Barriers to healthy nutrition and physical activity were more consistently related to individual-level and interpersonal-level factors; enablers tended to be linked with interpersonal-level factors. Knowledge gaps identified related to sedentary behaviour and sleep as well as environmental and policy levels of influence. Our review revealed that some barriers and enablers were unique to adolescents with obesity, which were either within or beyond their control. These findings highlight the importance of multilevel interventions to enable healthy lifestyle behaviours for weight management.

Summary Objective To explore parents' reasons for discontinuing tertiary-level care for paediatric weight management. Methods Participants were parents of 10–17year olds (body mass index [BMI] ≥85th percentile) who were referred for paediatric weight management. Parents were recruited from three Canadian sites (Vancouver, BC; Edmonton, AB; Hamilton, ON) and were eligible if their children attended at least one clinical appointment and subsequently discontinued care. Data were collected using semi-structured individual interviews that were digitally recorded, transcribed, and analysed using an inductive manifest content analysis. Results Parents (n=29) of children [mean age: 14.7±1.8years; mean BMI percentile: 98.9±1.6; n=17 (58.6%) boys] were primarily female (n=26; 89.7%), Caucasian (n=22; 75.9%), and had a university degree (n=23; 79.3%). Reasons for discontinuing care were grouped into three categories: (i) family factors ( e.g. , perceived lack of progress, lack of family support, children's lack of motivation), (ii) logistical factors ( e.g. , monetary costs, distance, scheduling), and (iii) health services factors ( e.g. , unmet expectations of care, perceived limited menu of services, no perceived need for further support). Conclusions A range of multi-level factors influenced attrition from tertiary-level paediatric weight management. Our data suggest that experimental research is needed to examine whether addressing reasons for attrition can enhance families' retention in care and ultimately improve health outcomes for children living with obesity.

Introduction Attrition in pediatric weight management is a substantial problem. This study examined factors associated with short- and long-term attrition from a lifestyle and behavioral intervention for parents of children with overweight or obesity. Method Fifty-two families with children ages 6 to 12 years old and body mass index at or above the 85th percentile participated in a randomized controlled trial focused on parents, comparing parent-based cognitive behavioral therapy with parent-based psychoeducation for pediatric weight management. We examined program attrition using two clinical phases of the intervention: short-term and long-term attrition, modeled using the general linear model. Predictors included intervention type, child/parent weight status, sociodemographic factors, and health of the family system. Results Higher self-assessed health of the family system was associated with lower short-term attrition; higher percentage of intervention sessions attended by parents was associated with lower long-term attrition. Discussion Different variables were significant in our short- and long-term models. Attrition might best be conceptualized based on short- and long-term phases of clinical, parent-based interventions for pediatric weight management.

Objective To assess registration and reporting details of randomized controlled trials (RCTs) published from 2011 to 2016 across four obesity journals. Methods All issues from four leading obesity journals were searched systematically for RCTs from January 2011 to June 2016. Data on registration status were extracted from manuscripts, online trial registries, and a trial database; corresponding authors were contacted for registration details, when necessary. The methodological reporting of RCTs was assessed on specific criteria from the Consolidated Standards of Reporting Trials. Results A total of 223 RCTs were reviewed. Three-quarters (n = 170) were registered publicly; 94 (55.3%) reported registration details in the manuscript, and 82 (48.2%) were registered prospectively. Newer RCTs were more likely to be registered prospectively than older RCTs (2014-2016: 57.3% vs. 2011-2013: 39.2%; c2 = 5.5, P = 0.02). Assessment on the Consolidated Standards of Reporting Trials demonstrated that less than half of all studies reported data collection dates (n = 108; 48.4%) or included “randomized trial” in the title (n = 89; 39.9%). Conclusions The methodological reporting of RCTs published in obesity journals is suboptimal, despite current guidelines and policies. To complement existing standards, editorial boards should incorporate mandatory fields within the online manuscript submission process to enhance the quality, transparency, and comprehensiveness of reporting RCTs in obesity journals.

Background Lifestyle modifications represent the first line of treatment in obesity management; however, many adolescents with obesity do not meet lifestyle recommendations. Given that adolescents are rarely consulted during health policy development and in the design of lifestyle interventions, their first-hand experiences, preferences, and priorities may not be represented. Accordingly, our purpose was to explore adolescents’ lifestyle treatment recommendations to inform policy and program decisions. Methods Conducted from July 2017 to January 2018, this study adhered to a qualitative, crosslanguage, patient-oriented design. We recruited 19 13–17-year-old adolescents (body mass index [BMI] ≥85th percentile) seeking multidisciplinary treatment for obesity in geographically and culturally diverse regions of Canada. Adolescents participated in one-on-one, in-person, semi-structured interviews in English or French. Interviews were audio-recorded, transcribed verbatim, managed using NVivo 11, and analyzed using quantitative and qualitative content analysis by two independent researchers. Results Adolescents’ recommendations were organized into five categories, each of which denotes health as a collective responsibility: (i) establish parental support within limits, (ii) improve accessibility and availability of ‘healthy foods’, (iii) limit deceptive practices in food marketing, (iv) improve accessibility and availability of varied physical activity opportunities, and (v) delay school start times. Respect for individual autonomy and decision-making capacity were identified as particularly important, however these were confronted with adolescents’ partial knowledge on nutrition and food literacy. Conclusions Adolescents’ recommendations highlighted multi-level, multi-component factors that influenced their ability to lead healthy lifestyles. Uptake of these recommendations by policy-makers and program developers may be of added value for lifestyle treatment targeting adolescents with obesity.

We evaluated changes in overweight, obesity, and severe obesity in a population of 4- to 6-year-olds from 2010 to 2017. Anthropometric data were collected during children's preschool immunization visits in Edmonton and Calgary, Alberta, Canada. Body mass index (BMI), BMI z scores, and weight status categories were based on the World Health Organization criteria. Across 8 years, we examined population-level data from 161 114 children in which the prevalence of overweight (17.8%-15.7%; P < .001) and obesity (4.7%-4.2%; .004) decreased, while severe obesity (2.4%-2.2%; .3) remained unchanged. Overweight decreased in both boys (19.2%-16.8%; P < .0001) and girls (16.4%-14.6%; .003); obesity decreased in boys (5.3%-4.4%; .005), but not girls (4.1%-3.9%; .2). Severe obesity was stable in both sexes. Annual household income and breast feeding had positive, but variable moderating effects on overweight and obesity exclusively. Overall, reductions in overweight and obesity were positive findings, but targeted strategies are needed to reduce severe obesity in preschoolers.

Aim - Long‐term evaluations of childhood obesity treatments are needed. We examined changes in weight and cardiometabolic risk 1 year after children completed individual family or group‐based weight management interventions. Methods - In 2009‐2010, 6‐ to 12‐year‐old children with overweight or obesity from Finnmark and Troms (Norway) were recruited after media coverage and randomised to 24 months of individual family (n = 49) or group intervention (n = 48). Individual family intervention included counselling by a paediatric hospital team and a public health nurse in the local community. Group intervention included meetings with other families and a multidisciplinary hospital team, weekly physical activity sessions and a family camp. The primary outcome body mass index (BMI) and cardiometabolic risk factors were analysed 12 months after intervention. Results - From baseline to 36 months, children's BMI increased 3.0 kg/m2 in individual family and 2.1 kg/m2 in group intervention (between‐group −0.9kg/m2, P = 0.096). Data were available from 62 children (64%). Between‐group differences in C peptide (P = 0.01) were detected in favour of group intervention. Pooled data from both treatment groups showed continued decrease in BMI standard deviation score (P < 0.001). Conclusion - No between‐group difference in BMI was observed 12 months after intervention. Both groups combined showed sustained decrease in BMI standard deviation score.
