Few studies in the US have assessed physical activity levels across worker groups, despite the increasingly sedentary milieu of contemporary US occupations and increasing obesity rates among US workers. The present study determined the proportion of US workers meeting the Healthy People 2010 Guidelines for leisure-time physical activity levels in major US occupational groups. ⋯ Leisure-time physical activity levels were sub-optimal among all major US worker groups, with substantial variability across occupations. As part of disease prevention, health professionals should promote increased physical activity levels among those occupations identified with very low rates of leisure-time physical activity.

Long-term effects of a playground markings and physical structures on children's recess physical activity levels.
The aim of the study was to investigate the impact of a playground redesign intervention across time on children's recess physical activity levels using combined physical activity measures and to evaluate the potential influence of covariates on the intervention effect. ⋯ The results suggest that a playground redesign, which utilizes multicolor playground markings and physical structures, is a suitable stimulus for increasing children's school recess physical activity levels.
