Purpose: To examine whether change in SB and PA associated with a change in weight status over 24-months. Methods: Data were from Identifying Determinants of Eating and Activity (IDEA), a 3-year longitudinal cohort study that assessed the etiology of adolescent obesity. PA and SB were assessed using the ActiGraph (Model 7164; ...
Background: The effects of physical activity (PA) in producing weight loss are well known. However, there is some controversy about the relationship between PA intensity and levels of obesity in children. Further, different cut-offs have been used to classify obesity, which may influence the observed associations with PA. The ...
Background: Children spend most of their awake time at school, where they are engaged in active and sedentary activities. As such, it is relevant to understand the importance of school environmental characteristics (SEC) related to children’s physical activity (PA). The main aim of the International Study of Childhood, Obesity, ...
Purpose: Identify age categories that maximize the correlation between MVPA and BMI percentile (BMI%) in child aged 2-5. Methods: MVPA was estimated from accelerometer data and summarized into minutes using cut-points suggest by Pate et al. The 228 children wore the monitors for 7 days. BMI% was computed using standard CDC criteria. ...
Background: Adults with intellectual disability (ID) are less physically active than persons without ID (WID). However, very little is known about physical activity (PA) patterns of ID children and adolescents. Purpose: To investigate PA patterns of Icelandic primary school children with mild-to-severe ID. Methods: Anthropometric measurements were obtained from 91 ID ...
Background: It well established that sedentarism (SED) adversely affects children´s health. Further, SED is a complex behavior and likely influenced by individual- and school-level predictors. The International Study of Childhood Obesity, Lifestyle, and Environment (ISCOLE) aims to determine the relationship between lifestyle characteristics and obesity in children, and ...
Background: Aerobic fitness, moderate-to-vigorous physical activity (MVPA), sedentary time (SED) and body mass index (BMI) are all associated with cardio-metabolic risk factors (CMRF) in children. However, few studies have examined the unique contribution of fitness to CMRF accounting for other covariates. Purpose: To evaluate the association between fitness and CMRF ...
Purpose: We compared physical activity (PA) barriers in overweight/obese and healthy weight seven to ten year olds. A secondary purpose was to evaluate the relationship between the number of barriers reported and minutes of moderate-to-vigorous physical activity (MVPA). Methods: :Currently, 19 participants have completed the study. Height and weight were ...
Background: Physical activity (PA) questionnaires are an affordable and time efficient tool that can be used by physicians to determine if individuals meet PA recommendations (≥150 min/week of moderate to vigorous PA [MVPA] accumulated in bouts ≥10 minutes). The Exercise Vital Signs EVS (Coleman et al. MSSE 2012) questionnaire was recently ...
Background: Multiple cutpoints exist for reducing raw accelerometry data into specific intensity categories (i.e. light, moderate, and vigorous). Historically, Freedson et al. (1998) uniaxial cutpoints have been most readily used. Multiple triaxial cutpoints now exist, but no standard interpretation methods have been accepted. Theoretically, using different interpretation methods may ...
