Independent associations between child and parent perceived neighborhood safety, child screen time, physical activity and BMI: a structural equation modeling approach

  • Published on June 23, 2015

Objective: The main objective of this study was to investigate whether children's perceptions of neighborhood safety are associated with their weight status and weight-related behaviors, independently of their parents' perceptions. Methods: Data were from the baseline wave (collected in 2005–2008) of the Quebec Adipose and Lifestyle Investigation in Youth (QUALITY), ...


Perceived parental social support and moderate-to-vigorous physical activity in children at risk of obesity

  • Published on June 2014

Purpose: Identification of factors that relate to physical activity behavior in children at higher risk for weight problems--namely, children with obese parents--is key to informing the development of effective interventions to promote physical activity and reduce obesity. The purpose of our study was to examine children's perceptions of parental social ...


Associations of Sedentary Behavior, Sedentary Bouts and Breaks in Sedentary Time with Cardiometabolic Risk in Children with a Family History of Obesity

  • Published on November 2013

Background Although reports in adults suggest that breaks in sedentary time are associated with reduced cardiometabolic risk, these findings have yet to be replicated in children. Purpose To investigate whether objectively measured sedentary behavior, sedentary bouts or breaks in sedentary time are independently associated with cardiometabolic risk in a cohort ...


Association between accelerometer-measured physical activity intensities and sedentary time in 8-10 year old children

  • Published on 2013

Abstract This study examines the association between objectively-measured physical activity (PA) intensities and sedentary behaviour (SED) in a cohort of 532 children aged 8-10 y. PA and SED were assessed by accelerometer over 7-days. Television and computer/video-game use were self-reported. Associations between PA intensities and SED variables were assessed by ...


Insulin secretion and its association with physical activity, fitness and screen time in children

  • Published on Oct. 16, 2013

Objective To determine the independent associations of moderate to vigorous physical activity (MVPA), fitness, screen time, and adiposity with insulin secretion in children. Design and Methods Caucasian youth (n = 423/630), 8-10 years old, with at least one obese biological parent, were studied (QUALITY cohort). Insulin secretion was measured using HOMA2...


Combined associations between moderate to vigorous physical activity and sedentary behaviour with cardiometabolic risk factors in children

  • Published on Jan. 21, 2013

Abstract The objective of this study was to examine the combined associations between time spent in moderate- to vigorous-intensity physical activity (MVPA) and time spent sedentary in relation to cardiometabolic risk factors in a cohort of Canadian children. A cross-sectional study was conducted on 536 white children aged 8–10 years with ...


Physical activity vs. sedentary time: independent associations with adiposity in children

  • Published on March 28, 2012

Objective To investigate the independent associations between objectively measured levels of movement intensity (i.e. time spent sedentary and at light, moderate and vigorous intensities) and indicators of adiposity in a cohort of Canadian children. Methods A cross-sectional study was conducted in 550 Caucasian children aged 8–10 years with at least ...


Adiposity and glucose intolerance exacerbate components of metabolic syndrome in children consuming sugar-sweetened beverages: QUALITY cohort study

  • Published on Nov. 21, 2012

Background Sugar-sweetened beverage (SSB) consumption is linked to weight gain and metabolic syndrome (MetS) components in children, but whether these associations are modified by excess weight and glucose tolerance status in children is not known. Objective The objective of this study was to examine the cross-sectional associations between SSB intake ...


Short Sleep Duration Is Independently Associated With Overweight and Obesity in Quebec Children

  • Published on September/October 2011

Objective To investigate the association of sleep duration with adiposity and to determine if caloric intake and physical activity mediate this relationship. Methods The Quebec Adiposity and Lifestyle Investigation in Youth (QUALITY) study is an ongoing longitudinal investigation of Caucasian children with at least one obese biological parent. Children (n=550) ...


How Are Physical Activity, Fitness, and Sedentary Behavior Associated With Insulin Sensitivity in Children?

  • Published on May 11, 2012

Objective To describe the associations among moderate-to-vigorous physical activity (MVPA), fitness, sedentary behavior (SB), and insulin sensitivity (IS). Research Designs & Methods Data were drawn from the baseline assessment of the QUALITY cohort, which included 630 white youth (aged 8–10 years at recruitment), with at least one obese biological parent. IS ...
