Characterizing the Metabolically Obese Normal Weight Phenotype in Youth

Henderson Melanie , Mathieu Marie-Eve , Benedetti Andrea , Barnett Tracie

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...

Social Networks, Social Support and Weight-Related Outcomes among Adolescents

Ybarra Marina , Yu Jennifer , Kakinami Lisa , Mathieu Marie-Eve , Henderson Melanie , Barnett Tracie

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...

The Impact of Diet on Insulin Dynamics over a 2-Year Period in Children with a Family History of Obesity

Leclerc Lucas , Gray-Donald Katherine , Benedetti Andrea , Radji Sanyath , Henderson Melanie

Background: Despite extensive evidence in adults that lifestyle modification, including a healthy diet, may prevent the onset of type 2 diabetes, studies examining the impact of chronic dietary exposures on insulin dynamics in at-risk children are lacking.Objective and hypotheses: To assess how dietary intake predicts insulin sensitivity and secretion over a 2-year period in children with a family history of obesity.Method: Data st...

Turn off and Turn in: The Influence of Television Viewing and Sleep on Lipid Profiles in Children

Manousaki Despoina , Radji Sanyath , Barnett Tracie , Mathieu Marie-Eve , Gray-Donald Katherine , Henderson Melanie

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...

Correlations Between Measures of Adiposity Across Childhood and Adolescence and the Intestinal Microbiota in 15-17 year-old Children with a Family History of Obesity: Preliminary Findings from the QUALITY Cohort

Henderson Melanie , Van Hulst Andraea , Simoneau Gabrielle , Barnett Tracie A. , Drapeau Vicky , Mathieu Marie-Eve , Nicolau Belinda , Varin Thibaut , Marette Andre

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...

More than A Gut Feeling: Preliminary Evidence Supporting a Role for Lifestyle Habits in Shaping the Intestinal Microbiota in Childhood and Adolescence

Henderson Melanie , Hulst Andraea Van , Simoneau Gabrielle , Barnett Tracie A , Drapeau Vicky , Mathieu Marie-Eve , Nicolau Belinda , Varin Thibaut , Marette Andre

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...

Promoting Healthy Lifestyles in Youth: Preliminary from the CIRCUIT Program

Ybarra Marina , Daniels Prince Kevin , Van Hulst Andraea , Barnett Tracie A , Mathieu Marie-Eve , Drouin Olivier , Kakinami Lisa , Bigras Jean-Luc , Henderson Melanie

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...

Determinants of Attrition from a Healthy Lifestyle Intervention: Experience from the CIRCUIT Program

Daniels Prince Kevin , Ybarra Marina , Van Hulst Andrea , Barnett Tracie A , Mathieu Marie-Eve , Drouin Olivier , Kakinami Lisa , Bigras Jean-Luc , Henderson Melanie

Introduction: Pediatric obesity is a global public health problem that is associated with severe cardiometabolic consequences. Weight management interventions focusing on lifestyles have shown some promising results, but attrition rates are often high and reasons for dropout are poorly understood.Objectives: We aimed toestimate the prevalence, and identify the determinants of attrition among pediatric participants in the first year of a 2-year lifestyle ...

Role of physical activity and sedentary behavior on early markers of cardiovascular disease in Canadian adolescents with and without type 1 diabetes: the CARDEA study

Harnois-Leblanc Soren , McNealis Vanessa , Friedrich Matthias G , Hulst AndraeaVan , Nuyt Anne-Monique , Bigras Jean-Luc , Barnett Tracie A. , Benedetti Andrea , Mathieu Marie-Eve , Drapeau Vicky , Sylvestre Marie-Pierre , Henderson Melanie ,

Background: Type 1 diabetes (T1D) is a risk factor for cardiovascular disease (CVD) and alterations may manifest as early as in adolescence. Increased physical activity and reduced sedentary behavior reduce the risk of CVD development in general adult populations, but knowledge is limited on their associations with early markers of CVD risk in pediatric T1D.Objective: Estimate associations of physical activity and sedent...
