Purpose: Ecological models of physical activity (PA) have shown influences on behavior at each level of the model. Ecological models for sedentary time (ST) have not been tested. This study aimed to examine the independent association of personal, social and environmental factors with objectively-measured sedentary time in a large, heterogeneous ...
Purpose: Most studies of neighbourhood features examine singular neighbourhood attributes, which may pattern in different ways. This study aimed to identify typologies of neighbourhood attributes and their associations with physical activity among children. Methods: The homes of 808 children aged 5-6 and 10-12 years were mapped in a Geographic Information System. ...
Purpose: The importance of greenspace for young people’s moderate-vigorous physical activity (MVPA) is still unknown. Few studies exist which combine accelerometry, Global Positioning System (GPS), and Geographic Information Systems (GIS) among youths. This study investigated the relationship between (i) amount of neighbourhood greenspace and MVPA, and (ii) MVPA time ...
Purpose: To assess whether the relationship of neighborhood walkability with physically active and sedentary time varied by weekday or weekend. Working adults may be less influenced by their home neighborhood environment during the work week when they spend more time away from home. Methods: Adults were recruited from neighborhoods in ...
Purpose: To examine opportunities for physical activity (PA) at child care and how they relate to the amount and intensity of PA. Methods: 44 children (mean age 4.1 yrs, 57% girls) from 5 centers wore accelerometers and were observed for average 7.6 hours/ day (total 29 days). Observers coded activities into: 1) Not an active play opportunity, 2) ...
Purpose: Regular physical activity (PA) in children is associated with improved health. The aims of this study were to describe the patterns of daily PA and to assess compliance with recommendations for total physical activity in preschool children. Methods: This study sample comprised 856 preschool children, aged 3 to 6 years. Children wore ...
Purpose: The FLASHE study is designed to collect data in adolescents and their parents in multiple domains of environment and behavior, with a specific focus on family relationships. The FLASHE study will examine the correlates of obesogenic and cancer preventive behaviors among adolescents and their parents across intra- and interpersonal ...
Purpose: The purpose of this study was to examine the correlation between parent and adolescent levels of physical activity, sedentary behaviors, and sleep among a group of overweight and obese adolescents. Methods: Baseline data of parent-adolescent pairs who enrolled in an E-health lifestyle modification intervention were analyzed for this paper (...
Purpose: Motherhood represents a critical window of change in the life-course including physical activity levels. No studies have objectively examined the daily cadence (patterns) of physical activity (PA) among dyads of preschool aged children and mothers. In this study we examined mother-child dyads’ PA levels across week and weekend day ...
Purpose: People with heart disease tend to experience a reduced health-related quality of life (QOL). Regular physical activity (PA) has been linked to improved outcomes, but little is known regarding the role of sedentary behavior. The objective of this study was to examine the association between sedentary behavior and QOL ...
