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 at ...


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 one ...


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 was ...


Actigraph Accelerometer-Defined Boundaries for Sedentary Behaviour and Physical Activity Intensities in 7 Year Old Children

  • Published on Aug. 11, 2011

Background Accurate objective assessment of sedentary and physical activity behaviours during childhood is integral to the understanding of their relation to later health outcomes, as well as to documenting the frequency and distribution of physical activity within a population. Purpose To calibrate the ActiGraph GT1M accelerometer, using energy expenditure (...



How active are our children? Findings from the Millennium Cohort Study

  • Published on Aug. 21, 2013

Objective To describe levels of physical activity, sedentary time and adherence to Chief Medical Officers (CMO) physical activity guidelines among primary school-aged children across the UK using objective accelerometer-based measurements. Design Nationally representative prospective cohort study. Setting Children born across the UK, between 2000 and 2002. Participants 6497 7-year-old to 8-year-old singleton children ...


Automatic Diagnosis of ADHD Based on Nonlinear Analysis of Actimetry Registries

  • Added on September 3, 2013

Introduction: Attention-Deficit Hyperactivity Disorder (ADHD) is the most common mental health problem in childhood and adolescence. Its diagnosis is commonly performed in a subjective manner since current objective measurements are either expensive or time-consuming. However, subjective methods tend to overestimate the severity of the pathology. In this paper, we propose ...
