Few longitudinal studies have examined the adoption of bans on smoking in private homes. ⋯ The proportion of households with smoking bans increased substantially, but households with smokers or family members who smoke remained less likely to implement bans. The importance of culturally sensitive programs to promote household bans cannot be overstated.

This article examines factors responsible for the stark racial disparities in HIV infection in the U. S. and the now concentrated epidemic among African Americans. ⋯ The social and economic environment in which many African Americans live shapes sexual network patterns and increases personal infection risk almost independently of personal behavior. The African-American HIV epidemic constitutes a national crisis whose successful resolution will require modifying the social and economic systems, structures, and processes that facilitate HIV transmission in this population.

People who hunt deer from elevated tree stands may improve the chances of a successful hunt but also risk serious injury from a fall to the ground. ⋯ Falls from tree stands associated with deer hunting are an increasing and important cause of injuries, especially for older hunters. Surveillance for tree stand-related injuries should be enhanced and preventive initiatives developed and tested.

Review Meta Analysis
Meta-analysis of workplace physical activity interventions.
Most adults do not achieve adequate physical activity levels. Despite the potential benefits of worksite health promotion, no previous comprehensive meta-analysis has summarized health and physical activity behavior outcomes from such programs. This comprehensive meta-analysis integrated the extant wide range of worksite physical activity intervention research. ⋯ These findings document that some workplace physical activity interventions can improve both health and important worksite outcomes. Effects were variable for most outcomes, reflecting the diversity of primary studies. Future primary research should compare interventions to confirm causal relationships and further explore heterogeneity.
