Background: Using ultrasound to examine the glandular breast tissue is a promising method for staging pubertal breast development. However, breast ultrasound for this purpose has not been explored in a large sample of healthy girls in different developmental stages, and normative data have been unavailable.Objective: To present novel pubertal references for breast ultrasound stages, Tanner breast (B) and pubic hair (PH) ...

Introduction: Male puberty is initiated by endocrine signaling in the hypothalamic-pituitary axis whereby follicle-stimulating hormone (FSH) and luteinizing hormone (LH) enable testicular maturation and synthesis of testosterone. Recent publications have eluded to overnutrition and obesity as relevant factors that may accelerate the timing of puberty. Attainment of testicular volume (TV) 4 ml measured by Prader orchidometer remains the definition of male puber...

Background: Although metabolically obese normal weight (MONW) adults are at increased risk of type 2 diabetes and cardiovascular disease (CVD), little is known regarding MONW children.Objective and hypotheses: To characterize lifestyle habits and insulin dynamics of MONW children.Method: Caucasian youth (n=630) aged 8–10 years, with at least one obese biological parent, were studied (QUALITY cohort). We defined MONW c...

Introduction: Childhood obesity rates have increased exponentially in the past three decades. Parental characteristics, such as weight status, physical activity (PA), education and smoking habits have been identified individually as being potential determinants of offspring obesity. However, no prospective studies have examined the joint impact of parental lifestyle habits on their offspring's adiposity. We identified clusters of parental characteristics, ...

Introduction: People’s weight-related behaviors may be influenced by their personal social network (SN), notably via family and friends’ behavioral modelling and motivational social support (SS).Objective: We examined the cross-sectional relation between social network-based social support (SS) and weight-related outcomes among adolescents ina pilot study within the QUALITY cohort, a longitudinal study investigating the natural...

Background: Physical activity is beneficial to lipid profiles, however the association between sedentary behaviours and paediatric dyslipidaemia remains controversial. Understanding these associations is critical given that youth are increasingly engaging in sedentary pursuits, and are sleeping, on average, 1 h less than children were 20 years ago.Objective and hypotheses: To investigate whether various forms of sedentary behavior/sleep predict lipid pro...

Background: Pituitary insufficiency and severe obesity are common sequelae of craniopharyngioma and its treatment. Once weekly glucagon-like Peptide 1 (GLP1) analog’s semaglutide has recently shown efficacy in adults with common obesity.Objective: We evaluated the efficacy and safety of Semaglutide, a once-weekly GLP-1 analog, in 6 children with craniopharyngioma and morbid obesity.Subjects an...

Background: While differences in gut microbiota between obese and lean subjects have been described, few studies have examined how adiposity across childhood relates to intestinal microbiota composition and diversity in late adolescence.Objective: To explore the correlations between measures of adiposity from childhood and adolescence with intestinal microbiota composition and diversity at 15–17 years.Methods: Data stem from t...

Background: Dietary intake has been shown to influence the composition and diversity of the gut microbiota in adults, however its impact in childhood and adolescence remains uncertain. Moreover, the impact of other lifestyle behaviors such as physical activity, sedentary behaviors, sleep and fitness on the gut microbiota has rarely been investigated.Objective: To explore the correlations between intestinal microbiota composition and meas...

Introduction: Childhood obesity is an international pandemic which affects 13% of Canadian youth, and is the leading cause of cardiovascular disease (CVD) in children. While the optimal approach to treat pediatric obesity remains elusive, comprehensive and intensive behavioral interventions which leverage the child’s living environment in order to promote improvements in healthy lifestyles appear promising. The CIRCUIT program (Centre Pédiatrique d’Intervent...
