Correlates of leisure-time physical activity during transitions to motherhood.

Despite growing evidence for an inverse relationship of motherhood and physical activity, studies of the possible correlates for behavior change are scant. The purpose of this study was to evaluate the change in leisure-time physical activity behaviors of 139 urban women during the transition to motherhood in retrospective analysis and evaluate their physical activity changes using the theory of planned behavior during motherhood. Perceptions of control based on time, fatigue, social support, and childcare were the critical correlates that distinguished between those who continued with physical activity and those who declined.

Integrating the perceived neighborhood environment and the theory of planned behavior when predicting walking in a Canadian adult sample.

Purpose: To integrate the characteristics of the perceived environment with the theory of planned behavior (TPB) to determine (1) whether the TPB mediates relations among environmental characteristics and walking, and (2) whether the environment moderates TPB-walking relations.

Design: Cross-sectional.

Setting: South Vancouver Island, British Columbia, Canada.
