International physical activity questionnaire: 12-country reliability and validity.
Considering the diverse samples in this study, IPAQ has reasonable measurement properties for monitoring population levels of physical activity among 18- to 65-yr-old adults in diverse settings. Expand
A review of correlates of physical activity of children and adolescents.
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. Expand
Compendium of physical activities: classification of energy costs of human physical activities.
A coding scheme is presented for classifying physical activity by rate of energy expenditure, i.e., by intensity, and general use of this coding system would enhance the comparability of results across studies using self reports of physical activity. Expand
An ecological approach to creating active living communities.
The thesis of this article is that multilevel interventions based on ecological models and targeting individuals, social environments, physical environments, and policies must be implemented toExpand
Correlates of physical activity: why are some people physically active and others not?
An understanding of correlates and determinants, especially in countries of low and middle income, could reduce the risk of future epidemics of inactivity and contribute to effective global prevention of non-communicable diseases. Expand
Correlates of adults' participation in physical activity: review and update.
There remains a need to better understand environmental influences and the factors that influence different types of PA and longitudinal and intervention studies will be required if causal relationships are to be inferred. Expand
Neighborhood-based differences in physical activity: an environment scale evaluation.
Neighborhood environment was associated with physical activity and overweight prevalence and the reliability and validity of self-reported neighborhood environment subscales were supported. Expand
Environmental correlates of walking and cycling: Findings from the transportation, urban design, and planning literatures
Research in transportation, urban design, and planning has examined associations between physical environment variables and individuals’ walking and cycling for transport. Constructs, methods, andExpand
The development of scales to measure social support for diet and exercise behaviors.
These scales are among the first measures of social support behaviors specific to dietary- and exercise-habit change and correlated with respective self-reported dietary and exercise habits, providing evidence of concurrent criterion-related validity. Expand
