Parents as Agents of Change in Managing Pediatric Obesity: A Randomized Controlled Trial Comparing Cognitive Behavioral Therapy versus Psychoeducation Interventions.

Background: Obesity interventions for parents of children with obesity can improve children's weight and health. This randomized controlled trial (RCT) evaluated whether a parent-based intervention based on cognitive behavioral therapy (CBT) principles was superior to a parent-based intervention based on a psychoeducation program (PEP) in improving children's obesity. Methods: This study was a pragmatic, two-armed, parallel, superiority RCT. Conducted at a Canadian outpatient pediatric obesity management clinic (September 2010-January 2014), this trial included families with children 8-12 years with an age- and sex-specific BMI ≥85th percentile. The 16-week manualized interventions were similar in content and delivered to parents exclusively, with different theoretical underpinnings. The primary outcome was children's BMI z-score at postintervention (4 months). Secondary outcomes included anthropometric, lifestyle, psychosocial, and cardiometabolic variables. Data were collected at preintervention (0 months), postintervention (4 months), 10, and 16 months. Intention-to-treat analysis using linear mixed models was used to assess outcomes. Results: Among 52 randomly assigned children, the mean age (standard deviation) was 9.8 (1.7) years and BMI z-score was 2.2 (0.3). Mean differences in BMI z-score were not significantly different between the CBT (n = 27) and PEP (n = 25) groups from 0 to 4-, 10-, and 16-month follow-up. At 4 months, the mean difference in BMI z-score from preintervention between the CBT (-0.05, 95% CI = -0.09 to 0.00) and PEP (-0.04, 95% CI = -0.09 to 0.01) groups was -0.01 (95% CI = -0.08 to 0.06, p = 0.80). Similar results were found across all secondary outcomes. Conclusions: Our CBT-based intervention for parents of children with obesity was not superior in reducing BMI z-score vs. our PEP-based intervention.

Impact of COVID-19 Pandemic on Adolescents and Young Adults Living With Type 2 Diabetes.

OBJECTIVES: The aim of this study was to assess the impacts of the COVID-19 pandemic on adolescents and young adults living with type 2 diabetes (T2D) involved in the national Improving Renal Complications in Adolescents with T2D through REsearch (iCARE) study. METHODS: The Environmental influences on Child Health Outcomes (ECHO) COVID-19 Questionnaire developed by the National Institutes of Health ECHO COVID-19 Task Force was administered to participants (n=85) from the iCARE study between June 2020 and October 2020. Children 12 years old (via parent report) and adolescents and young adults ≥13 years old (via self-report) participated. The questionnaire assessed the impact of the pandemic on health-care appointments, lifestyle, internet use, social connections and mental health. RESULTS: Participants were 17.0±3.1 (range, 12 to 27) years of age and predominantly female (61.3%). During the pandemic, 69.4% were able to attend their health-care appointments by telephone or virtual platforms, 31.7% ate more, 45.1% slept more and 29.3% spent less time on physical activities. There was an increase in internet use for both educational (42.0%) and noneducational purposes (54.9%). Participants felt less socially connected (64.6%). Participants also felt sometimes (59.2%), often (19.7%) and very often (6.7%) satisfied with their lives. DISCUSSION: Our study revealed that the COVID-19 pandemic has had various impacts on the daily lives of adolescents and young adults living with T2D. Future research should include longitudinal studies of the health burden of the COVID-19 pandemic on this population, with a more in-depth evaluation of mental health outcomes and clinical outcomes.

Metaphyseal and posterior rib fractures in osteogenesis imperfecta: Case report and review of the literature.

PURPOSE: Metaphyseal corner fractures and posterior rib fractures are thought to only occur in settings of inflicted injury. We describe a case of siblings who presented with metaphyseal corner fractures and multiple posterior rib fractures who were later found to carry FKBP10 mutations, a rare cause of Osteogenesis Imperfecta (OI) known as Bruck syndrome. This clinical presentation led to a literature review examining fracture types in OI and inflicted injury. CASES: A 15-month-old male presented with multiple healing fractures of varying ages including posterior rib and metaphyseal corner fractures with no history of significant trauma. He had joint laxity, short stature and Wormian bones. His diagnosis of Bruck Syndrome led to investigations in his sibling at birth, which demonstrated the same fracture pattern including multiple posterior rib and metaphyseal corner fractures. They both had pathogenic compound heterozygous FKBP10 variants. LITERATURE REVIEW AND RESULTS: We performed a literature review evaluating the fracture pattern in cases investigated for inflicted injury and found to have OI. Fourteen articles reported 78 children with OI initially diagnosed as inflicted injury. Of these children, 71 (91%) were diagnosed with milder forms of OI (Sillence type I and IV). Sixty-four children (81%) had clinical signs of OI including blue sclera, dentinogenesis imperfecta, short stature, joint laxity and limb bowing. Fifteen (19%) children had fractures of high specificity for inflicted injury including metaphyseal corner fractures and posterior rib fractures and 58 (74%) had fractures of moderate specificity for inflicted injury such as bilateral fractures and fractures of different ages. CONCLUSION: Metaphyseal corner fractures and posterior rib fractures are highly associated with inflicted injury, but they have been reported in children with OI. Bruck syndrome, a rare and severe form of OI can present with metaphyseal and posterior rib fractures, including at birth. When features of OI are present in children with metaphyseal corner fractures and/or posterior rib fractures are present, genetic testing may be warranted.

Comparison of Clinical and Social Characteristics of Canadian Youth Living With Type 1 and Type 2 Diabetes.

OBJECTIVES: Our aim in this study was to describe the clinical and social characteristics of 2 Canadian cohorts of adolescents with diabetes. METHODS: Participants from the Improving renal Complications in Adolescents with type 2 diabetes through REsearch (iCARE) study (n=322) and the Early Determinants of Cardio-Renal Disease in Youth With Type 1 Diabetes (n=199) study were compared. RESULTS: Adolescents were 10 to 18 years of age (mean ± standard deviation: 14.8±2.4 years). The T2DM cohort had a shorter duration of diabetes. Both groups had glycated hemoglobin levels above target. The type 2 diabetes (T2D) cohort was comprised of predominantly Indigenous youth. The type 1 diabetes (T1D) cohort was 58.3% European/Caucasian, with a high proportion (41.7%) of visible minority groups (Afro-Caribbean, Asian/Pacific Islander, Hispanic). The prevalence of obesity, hypertension, left ventricular hypertrophy, albuminuria and hyperfiltration was higher in the T2D cohort. The T1D cohort was more socially and economically advantaged in all 4 dimensions of health inequality. CONCLUSIONS: There are significant differences in clinical and social characteristics of adolescents with T2D and T1D in Canada. Both have inadequate glycemic control with evidence of onset and progression of diabetes-related complications.

ApoB-lipoprotein remnant dyslipidemia and high-fat meal intolerance is associated with markers of cardiometabolic risk in youth with obesity.

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 < .0001, and apoB48AUC : 173.0 ± 20.86 vs 61.99 ± 3.44, P < .001). Furthermore, fasting plasma apoB48-remnants were positively correlated with the non-fasting response in apoB48AUC (r = 0.84, P < .0001) as well as other cardiometabolic risk factors including HOMA-IR (r = 0.61, P < .001) and leptin (r = 0.56, P < .0001). CONCLUSION: Fasting apoB48-remnants are elevated in youth with obesity and predict apoB48 postprandial dyslipidemia. ApoB48-remnants are associated with the extent of fat intolerance and appear to be potential biomarker of CVD-risk in youth.

Families' perceived benefits of home visits for managing paediatric obesity outweigh the potential costs and barriers.

AIM: Home visits have successfully been used to deliver various health services, but what role could they play in paediatric weight management? Low treatment initiation and high attrition prompted our multidisciplinary paediatric weight management clinic to investigate how families perceived the benefits and barriers of home visits. METHODS: We focused on children with obesity aged 2-17 who were enrolled in our tertiary-level clinic in Alberta, Canada. None had received a home visit. The families were interviewed face-to-face from October 2015 to October 2016, and we used a qualitative description methodological framework and manifest content analysis. The parents were the main interviewees. RESULTS: Of the 56 families, 89% were interested in a home visit, 82% wanted support from a dietician and 54% from an exercise specialist. The perceived benefits of home visits included comprehensive assessment (95%), convenience (86%), tailored care (29%) and family involvement (13%), while the costs and barriers included clinicians' potential judgmental attitudes (30%), loss of privacy (19%) and distractions (10%). Some thought clinicians would find home visits inconvenient (25%), with bureaucratic challenges (14%) and sustainability issues (5%). CONCLUSION: Families felt home visits were a convenient option for managing paediatric obesity and identified important benefits and barriers that could guide such interventions.

Impaired ApoB-Lipoprotein and Triglyceride Metabolism in Obese Adolescents With Polycystic Ovary Syndrome.

CONTEXT: Adolescents with polycystic ovary syndrome (PCOS) have atherogenic dyslipidemia and increased cardiovascular disease (CVD) risk, and this is exacerbated in obesity. OBJECTIVE: To determine and compare fasting and nonfasting lipid and apolipoprotein (Apo)B-lipoprotein metabolism in 3 groups of adolescent girls: healthy-weight controls, obese without PCOS (obese-control), and obese with PCOS (obese-PCOS). DESIGN, SETTING, AND PARTICIPANTS: Participants aged 12 to 17 years were recruited for this cross-sectional study from a pediatric weight management clinic and the local community in Alberta, Canada. MAIN OUTCOME MEASURES: Plasma lipids and ApoB lipoproteins, including triglycerides (TGs) and ApoB100- and ApoB48-lipoproteins, were measured in the fasted and postprandial state following a high-fat meal. RESULTS: Obese-control (n = 12) and obese-PCOS (n = 18) groups had twofold higher concentrations of fasting plasma TG and ApoB100- and ApoB48-lipoprotein remnants compared to healthy-weight controls (n = 10) (ApoB48-lipoproteins: 19.32 ± 2.10, 24.02 ± 4.28, and 8.95 ± 1.05 µg/mL, respectively; P < 0.001). The obese-PCOS group had 50% higher fasting plasma TG level compared to the obese-control group. The postprandial response was higher in both obese-controls and obese-PCOS subjects compared with healthy-weight controls in plasma TG area under the curve (AUC) (1028.0 ± 83.67, 1587.01 ± 259.6, and 615.42 ± 76.42 µg/mL⋅h, respectively; P < 0.01) and ApoB48(AUC) (191.30 ± 19.06, 238.8 ± 37.73, and 96.58 ± 9.17 µg/mL⋅h, respectively; P < 0.0001). Nonfasting plasma TG(AUC) and ApoB48(AUC) were positively correlated with free testosterone (r = 0.38; P < 0.001 and r = 0.33; P < 0.05, respectively), and these relationships were highly associated with insulin and body mass index. CONCLUSIONS: Adolescent girls with obesity and PCOS have elevated fasting and postprandial plasma TG and ApoB-lipoprotein remnants, providing evidence of early subclinical CVD risk, and these indices are highly associated with impaired insulin metabolism and hyperandrogenemia.

Predictors of Short- and Long-Term Attrition From the Parents as Agents of Change Randomized Controlled Trial for Managing Pediatric 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.

46,XY disorder of sex development due to 17-beta hydroxysteroid dehydrogenase type 3 deficiency: a plea for timely genetic testing.

BACKGROUND: 17ß-hydroxysteroid dehydrogenase type 3 (17ßHSD3) deficiency is a rare cause of disorder of sex development (DSD) due to impaired conversion of androstenedione to testosterone. Traditionally, the diagnosis was determined by ßHCG-stimulated ratios of testosterone:androstenedione < 0.8. CASE PRESENTATION: An otherwise phenotypically female infant presented with bilateral inguinal masses and a 46,XY karyotype. ßHCG stimulation (1500 IU IM for 2 days) suggested 17ßHSD3 deficiency although androstenedione was only minimally stimulated (4.5 nmol/L to 5.4 nmol/L). Expedient genetic testing for the HSD17B3 gene provided the unequivocal diagnosis. CONCLUSION: We advocate for urgent genetic testing in rare causes of DSD as indeterminate hormone results can delay diagnosis and prolong intervention.

The Edmonton Obesity Staging System for Pediatrics: A proposed clinical staging system for paediatric obesity.

Traditionally, clinical recommendations for assessing and managing paediatric obesity have relied on anthropometric measures, such as body mass index (BMI), BMI percentile and/or BMI z-score, to monitor health risks and determine weight management success. However, anthropometric measures do not always accurately and reliably identify children and youth with obesity-related health risks or comorbidities. The authors propose a new clinical staging system (the Edmonton Obesity Staging System for Pediatrics, EOSS-P), adapted from the adult-oriented EOSS. The EOSS-P is used to stratify patients according to severity of obesity-related comorbidities and barriers to weight management into four graded categories (0 to 3) within four main health domains: metabolic, mechanical, mental health and social milieu (the 4Ms). The EOSS-P is based on common clinical assessments that are widely available and routinely completed by clinicians, and has the potential to provide clinical and prognostic information to help evaluate and inform the management of paediatric obesity.

D'ordinaire, les recommandations cliniques pour évaluer et prendre en charge l'obésité juvénile reposent sur des mesures anthropométriques, telles que l'indice de masse corporelle (IMC), le percentile d'IMC ou l'écart réduit de l'IMC, pour surveiller les risques sur la santé et déterminer la bonne gestion du poids. Cependant, les mesures anthropométriques ne permettent pas toujours de déterminer avec précision et fiabilité les enfants et les adolescents présentant des risques de santé ou des comorbidités liés à l'obésité. Les auteurs proposent un nouveau système clinique d'établissement du stade de l'obésité (le système d'Edmonton pour évaluer le stade de l'obésité, ou EOSS-P), adapté de l'EOSS destiné aux adultes. L'EOSS-P est utilisé pour stratifier les patients selon la gravité des comorbidités liées à l'obésité et les obstacles à la gestion du poids en quatre catégories (0 à 3) tirées de quatre grands domaines de santé : métabolique, mécanique, santé mentale et milieu social (les 4M). L'EOSS-P, qui repose sur des évaluations cliniques courantes généralisées souvent remplies par les cliniciens, peut fournir de l'information clinique et pronostique pour contribuer à évaluer et étayer la prise en charge de l'obésité juvénile.

Lifestyle Behaviors of Parents of Children in Pediatric Weight Management: Are They Meeting Recommendations?

OBJECTIVE: Our objective was to examine the lifestyle behaviors of parents of children in pediatric weight management. METHODS: Parents were recruited upon presentation of their children (body mass index [BMI] ≥85th percentile) to a pediatric weight management clinic. Parents' demographic, anthropometric, and lifestyle habit data were collected by self-report. Parents were grouped into weight status categories based on their BMIs; lifestyle data were compared across BMI categories and to national recommendations. RESULTS: Parents (n = 266; 84% women; BMI, mean ± SD, 31.8 ± 7.2 kg/m(2)) were predominantly overweight/obese (82%), and most did not meet dietary recommendations (71%). Healthy-weight parents reported more daily steps versus parents who were overweight/obese (all P < .05). Most parents (~60%) met guidelines for physical activity, sedentary activity, and sleep. CONCLUSION: The high prevalence of overweight and obesity combined with suboptimal dietary behaviors highlight the need to address both children's and parents' lifestyle habits in pediatric weight management.

It's like rocket science only more complex: challenges and experiences related to managing pediatric obesity in Canada.

Pediatric obesity is an urgent and complex public health issue. Approximately one-third of Canadian children are overweight or obese, a proportion that highlights the need for effective and accessible services to improve short- and long-term health risks. In our experience, we have encountered a number of challenges common in pediatric obesity management across our clinical and research centers. For the purpose of this review, these challenges and our real-world experiences are grouped as issues that span (i) caring for children, adolescents, and families, (ii) collaborating with colleagues and (iii) working within the health care system. Collectively, we highlight a number of lessons learned from our years of experience and detail ongoing initiatives designed to optimize health services for managing obesity for children and adolescents in Canada.

Modest treatment effects and high program attrition: The impact of interdisciplinary, individualized care for managing paediatric obesity.

BACKGROUND: There is an urgent need to identify effective weight management interventions in real-world, clinical settings to improve the health of children with obesity. OBJECTIVES: To determine the impact of individualized, interdisciplinary care on the weight status of children with obesity; to assess the relationship between clinical interactions and change in participants' weight status; and to document the degree of program attrition. METHODS: A retrospective medical record review of clinical and administrative data from a paediatric weight management clinic in Edmonton, Alberta, was performed, which included data from a group of five- to 18-year-olds (body mass index [BMI] ≥85th percentile) collected from 2008 to 2012. Demographic, anthropometric and attendance data were retrieved from baseline and follow-up at three-, seven- and 11-month timepoints. The primary outcomes were participants' BMI z-score and change in BMI z-score over time. RESULTS: Data from 165 individuals were included. Among those with follow-up anthropometric data, weight stabilization occurred at three (n=127) and seven months (n=84). For individuals with follow-up anthropometric data at 11 months (n=44), BMI z-score tended to decrease over time (-0.05±0.12 units; P=0.06). Program attrition increased over time (23%, 49% and 73% at three-, seven- and 11-month follow-ups, respectively). Between presentation and three-month follow-up, there was an inverse relationship between the number of clinical appointments attended and change in BMI z-score (r= -0.18; P=0.04), an association that became nonsignificant at seven and 11 months (both P>0.05). CONCLUSION: An individualized, interdisciplinary weight management intervention led to weight stabilization and a modest weight reduction in children with obesity. Strategies to minimize program attrition are needed to optimize family engagement in care and success in managing paediatric obesity.

HISTORIQUE: Il est urgent de trouver des interventions efficaces de gestion du poids en milieu clinique pour améliorer la santé des enfants obèses. OBJECTIFS: Déterminer les effets de soins personnalisés et interdisciplinaires sur le poids d'enfants obèses, évaluer le lien entre les interactions cliniques et les modifications au poids des participants et établir le taux d'abandon du programme. MÉTHODOLOGIE: Les chercheurs ont procédé à une analyse rétrospective des dossiers médicaux et des données administratives d'une clinique pédiatrique de gestion du poids d'Edmonton, en Alberta, qui incluait les données d'un groupe de jeunes de cinq à 18 ans (indice de masse corporelle [IMC] ≥85e percentile) colligées entre 2008 et 2012. Ils ont extrait les données démographiques, anthropométriques et de participation initiales, puis aux suivis de trois, sept et 11 mois. Les résultats primaires étaient l'écart réduit de l'IMC et le changement à cet écart au fil du temps. RÉSULTATS: Les données de 165 personnes ont été incluses dans l'étude. Parmi les personnes qui possédaient des données anthropométriques de suivi, on a observé une stabilisation du poids au bout de trois (n=127) et sept mois (n=84). Chez les personnes qui possédaient des données anthropométriques au suivi de 11 mois (n=44), l'écart réduit de l'IMC avait tendance à diminuer au fil du temps (−0,05±0,12 unités; P=0,06). L'abandon du programme a augmenté dans le temps (23 %, 49 % et 73 % au suivi de trois, sept et 11 mois, respectivement). Entre la présentation et le suivi de trois mois, le lien entre le nombre de rendez-vous cliniques auquel les patients avaient assisté était inversement proportionnel à la modification de l'écart réduit de l'IMC (r= −0,18; P=0,04), une association qui n'était plus significative au suivi de sept et 11 mois (tous deux P>0,05). CONCLUSION: Une intervention personnalisée et interdisciplinaire a suscité la stabilisation du poids et une légère perte de poids chez des enfants obèses. Des stratégies pour réduire au minimum l'abandon du programme s'imposent pour optimiser la participation familiale aux soins et réussir à gérer l'obésité en pédiatrie.

A meal high in saturated fat evokes postprandial dyslipemia, hyperinsulinemia, and altered lipoprotein expression in obese children with and without nonalcoholic fatty liver disease.

BACKGROUND: Hyperinsulinemia and altered lipid and lipoprotein metabolism induced by fast-food diets may contribute to nonalcoholic fatty liver disease (NAFLD). We hypothesized that a high saturated fat (SFA) meal would evoke prolonged postprandial lipemia and hyperinsulinemia, increased inflammation, and altered lipoprotein expression in obese children with NAFLD when compared with healthy children. METHODS: We prospectively studied 31 children (NAFLD, 13.1 ± 2.6 years, n = 11; age-matched obese, 14.3 ± 1.7 years, n = 9; lean, 13.6 ± 2.6 years, n = 11) following consumption of a high SFA (18.8%) meal. Prior to and at 1, 3, and 6 hours after meal consumption, blood was collected for analysis of alanine aminotransferase (ALT); aspartate aminotransferase (AST); γ-glutamyltransferase; leptin; C-reactive protein; (fasting) insulin; glucose; triglycerides (TGs); total, high-density lipoprotein, and low-density lipoprotein cholesterol; adiponectin; nonesterified fatty acids (NEFAs); inflammatory markers (TNF-α, IL-6, IL-10); apolipoproteins-B48, B100, and CIII; and fatty acid (FA) composition of TG fractions. RESULTS: Children with NAFLD had significantly higher fasting levels of ALT (87 ± 54 U/L), AST (52 ± 33.5 U/L), and apolipoprotein-CIII (20.6 ± 11.3 mg/dL) with postprandial hyperinsulinemia (iAUC insulin: 225 ± 207 [NAFLD] vs 113 ± 73 [obese] vs 47 ± 19.9 [lean] mU/L-h; P < .001); suppression of NEFA (iAUC-NEFA: 1.7 ± 0.9 [NAFLD] vs 0.6 ± 0.3 [obese] vs 1 ± 0.7 [lean] mEq/L-h); and prolonged elevations in apolipoprotein-B48 3-6 hours after meal consumption when compared with obese and lean controls (P < .05). CONCLUSION: A meal high in saturated fat evokes postprandial dyslipemia, hyperinsulinemia, and altered lipoprotein expression in obese children with and without NAFLD.

Parents as agents of change (PAC) in pediatric weight management: the protocol for the PAC randomized clinical trial.

BACKGROUND: There is an urgent need to develop and evaluate weight management interventions to address childhood obesity. Recent research suggests that interventions designed for parents exclusively, which have been named parents as agents of change (PAC) approaches, have yielded positive outcomes for managing pediatric obesity. To date, no research has combined a PAC intervention approach with cognitive behavioural therapy (CBT) to examine whether these combined elements enhance intervention effectiveness. This paper describes the protocol our team is using to examine two PAC-based interventions for pediatric weight management. We hypothesize that children with obesity whose parents complete a CBT-based PAC intervention will achieve greater reductions in adiposity and improvements in cardiometabolic risk factors, lifestyle behaviours, and psychosocial outcomes than children whose parents complete a psycho-education-based PAC intervention (PEP). METHODS/DESIGN: This study is a pragmatic, two-armed, parallel, single-blinded, superiority, randomized clinical trial. The primary objective is to examine the differential effects of a CBT-based PAC vs PEP-based PAC intervention on children's BMI z-score (primary outcome). Secondary objectives are to assess intervention-mediated changes in cardiometabolic, lifestyle, and psychosocial variables in children and parents. Both interventions are similar in frequency of contact, session duration, group facilitation, lifestyle behaviour goals, and educational content. However, the interventions differ insofar as the CBT-based intervention incorporates theory-based concepts to help parents link their thoughts, feelings, and behaviours; these cognitive activities are enabled by group leaders who possess formal training in CBT. Mothers and fathers of children (8-12 years of age; BMI ≥85th percentile) are eligible to participate if they are proficient in English (written and spoken) and agree for at least one parent to attend group-based sessions on a weekly basis. Anthropometry, cardiometabolic risk factors, lifestyle behaviours, and psychosocial health of children and parents are assessed at pre-intervention, post-intervention, 6-, and 12-months follow-up. DISCUSSION: This study is designed to extend findings from earlier efficacy studies and provide data on the effect of a CBT-based PAC intervention for managing pediatric obesity in a real-world, outpatient clinical setting. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01267097.

Xanthomata and diabetes in an adolescent with familial dysbetalipoproteinemia 9 yr after valproate-induced pancreatitis.

A 14-yr-old girl presented with eruptive xanthomata and hypertriglyceridemia. This rare presentation led to diagnoses of diabetes and familial dysbetalipoproteinemia. Type 1 diabetes is a common childhood illness often presenting in adolescence. However, this patient's past medical history revealed valproate-induced severe acute pancreatitis with necrosis at the age of 5 yr. Diabetes, in this case, developed 9 yr later as a result of inadequate pancreatic tissue to support increasing insulin requirements during growth and adolescence. Diabetes was discovered only after the appearance of cutaneous eruptive xanthomata, which appeared due to the previously undiagnosed genetic dyslipidemia. Although the relationship between xanthomata, hypertriglyceridemia, and diabetes may be well known in adults, in children, xanthomata are very rarely the presenting feature of diabetes of any cause. The patient was treated with insulin which induced rapid resolution of hypertriglyceridemia and gradual disappearance of xanthomata. This case acknowledges the rarity of diabetes presenting with xanthomata in adolescence, highlights the importance of searching for an underlying dyslipidemia in such a case, and presents diabetes as a long-term complication of acute pancreatitis in children.

In search of quality evidence for lifestyle management and glycemic control in children and adolescents with type 2 diabetes: A systematic review.

BACKGROUND: Our purpose was to evaluate the impact of lifestyle behavior modification on glycemic control among children and youth with clinically defined Type 2 Diabetes (T2D). METHODS: We conducted a systematic review of studies (randomized trials, quasi-experimental studies) evaluating lifestyle (diet and/or physical activity) modification and glycemic control (HbA1c). Our data sources included bibliographic databases (EMBASE, CINAHL®, Cochrane Library, Medline®, PASCAL, PsycINFO®, and Sociological Abstracts), manual reference search, and contact with study authors. Two reviewers independently selected studies that included any intervention targeting diet and/or physical activity alone or in combination as a means to reduce HbA1c in children and youth under the age of 18 with T2D. RESULTS: Our search strategy generated 4,572 citations. The majority of citations were not relevant to the study objective. One study met inclusion criteria. In this retrospective study, morbidly obese youth with T2D were treated with a very low carbohydrate diet. This single study received a quality index score of < 11, indicating poor study quality and thus limiting confidence in the study's conclusions. CONCLUSIONS: There is no high quality evidence to suggest lifestyle modification improves either short- or long-term glycemic control in children and youth with T2D. Additional research is clearly warranted to define optimal lifestyle behaviour strategies for young people with T2D.
