Effects of obesity, social interactions, and physical environment on physical activity in preschoolers
TLDR
Using regression-modeling procedures, results revealed a significant relationship between a child's relative weight, parental weight status, and percentage of time spent outdoors (environment) and children's activity levels and Parental obesity was associated with lower levels of physical activity in children.Abstract:
Examined demographic, environmental, and parent-child interactional correlates of physical activity in a group of 222 preschoolers. Activity levels were assessed with a system that quantified directly observed physical activity in the natural environment. Using regression-modeling procedures, results revealed a significant relationship between (a) child's relative weight, parental weight status, and percentage of time spent outdoors (environment) and (b) children's activity levels. Parental obesity was associated with lower levels of physical activity in children, childhood relative weight was associated with slightly higher levels of physical activity, and more outdoor activity was associated with higher activity levels. Parental participation in children's activities also significantly interacted with levels of parental obesity in predicting activity levels. Those children with a 50% risk for obesity (as defined by both, one, or neither parent being overweight) had small changes in activity across levels of parent-child interaction, whereas those at higher risk for obesity responded with increased activity as parent-child interactions increased. Results are discussed, and the implications of these findings for future intervention efforts are examined.read more

A review of correlates of physical activity of children and adolescents.
TL;DR: Variables that were consistently associated with children's physical activity were sex (male), parental overweight status, physical activity preferences, intention to be active, perceived barriers, previous physical activity, healthy diet, program/facility access, and time spent outdoors.

Childhood overweight: a contextual model and recommendations for future research
TL;DR: It is concluded that future research needs to adopt a broader contextual approach in order to understand and intervene against the processes leading to the development of overweight among children and that the use of theories or paradigms such as EST will facilitate developing and testing models of causal processes.

Environmental and policy interventions to promote physical activity
TL;DR: In this article, a model describing the development of policy and environmental interventions is proposed, in the hope of stimulating more research in this area, and two studies showed that placing signs encouraging stair use can be effective.

Determinants of Adolescent Physical Activity and Inactivity Patterns
TL;DR: Investigation of environmental and sociodemographic determinants of physical activity and inactivity patterns among subpopulations of US adolescents shows important associations between modifiable environmental factors, such as participation in school PE and community recreation programs, with activity patterns of adolescents.

TL;DR: Most consistent positive correlates of PA were father's PA, time spent outdoors and school PA‐related policies, and support from significant others, mother’s education level, family income, and non‐vocational school attendance (in adolescents).

TL;DR: It is concluded that a low rate of energy expenditure may contribute to the aggregation of obesity in families.
