Purpose: Grounded in the behavioral ecological model, and to address a lack of park space, this study looked at community members' use of public high school physical activity (PA) facilities during nonschool hours while considering the effects of seasonality. Method: Data included 3,959 observation sweeps across 19 public high school campuses over…

Background: Individuals with Down syndrome (DS) are less physically active than the general population, but limited data on objective physical activity patterns in adults with DS are available. Methods: Free-living physical activity was measured by waist-worn accelerometry in adults with DS from 2018 to 2020. Data were analysed using descriptive…

The purpose of this study was to examine the association between sexual identity-behavior concordance and discordance with meeting recommendations for 24-hour movement behaviors in adolescents. Participants were US adolescents who reported a history of sexual partners from the 2015-2019 National Youth Risk Behavior Survey (N = 19688; 49.3%…

The purpose of this study was to describe the accelerometry-based characteristics of overall sedentary behavior (SB) and sitting among adults under free-living conditions. Thirty-six (mean age 47.6 years) volunteers carried a waist-worn accelerometer for =4 days with data =600 min/d during 14 consecutive days. A machine learning (ML) based method…

Background: Sedentary behavior (SB) is related to unhealthy outcomes and is performed in many contexts, including school. The aim of this study was to identify sociodemographic, biological, and psychosocial correlates of SB performed at school in a sample of adolescents. Methods: Adolescents provided information regarding sex, age, socioeconomic…

Engagement in excessive sedentary behaviour represents a health risk for adolescents. The current study aimed to investigate patterns of sedentary behaviour amongst Irish female adolescents aged between 15 and 19 years old. 314 adolescents completed a questionnaire on their sedentary behaviour habits, health behaviours (physical activity, smoking,…

Background: Physical education (PE) plays a critical role in the healthy development of youth; however, the influence of PE classes in helping to provide students with health-related behavior patterns is not clear. This study aims to analyze whether participation in PE classes is associated with health-related behavior among high school students.…

This study was designed to test the validity of a transtheoretical model's physical activity (PA) stage measure with intention and different intensities of behavior in a large population-based sample of adults living with diabetes (Type 1 diabetes, n = 697; Type 2 diabetes, n = 1,614) and examine different age groups. The overall…

The aims of this study were to: (a) compare physical activity across two seasons and, within those seasons, across school and vacation time, and (b) compare the proportion of children meeting the activity thresholds recommended by Tudor-Locke et al. (2004) at each time point. Thirty-six boys, between the ages of 8 and 10 years (M age = 8.8 years,…

Analyzes why so many adults are inactive by examining how children are introduced to physical activity, focusing on two behavioral principles that are germane to turning children on to physical activity (fun and self-worth), reviewing practices that violate these principles, and speculating about why the principles get violated.
