Telephone-delivered interventions targeting physical activity and dietary change have potential for broad population reach and thus have a role to play in addressing increasing rates of lifestyle-related chronic diseases. The purpose of this systematic review is to update the evidence for their potential to inform translation, including effectiveness in promoting maintenance, reporting on implementation, and costs. ⋯ Given the strength of evidence for telephone-delivered physical activity and dietary change interventions, greater emphasis on dissemination studies is warranted.

The GPS represents an innovative way to objectively assess the spatial locations of physical activity behavior. The aim of this systematic review was to determine the capability of GPS to collect high-quality data on the location of activities in research on the relationship between physical activity and the environment. ⋯ GPS is a promising tool for improving understanding of the spatial context of physical activity. The current findings suggest that the choice of an appropriate device and efforts to maximize participant adherence are key to improving data quality, especially over longer study periods.

Research examining the association between environmental attributes and physical activity among youth is growing. An updated review of literature is needed to summarize the current evidence base, and to inform policies and environmental interventions to promote active lifestyles among young people. ⋯ Mode of measurement greatly influenced the consistency of associations between environmental attributes and youth physical activity. For both children and adolescents, the most consistent associations involved objectively measured environmental attributes and reported physical activity. The most supported correlates for children were walkability, traffic speed/volume, access/proximity to recreation facilities, land-use mix, and residential density. The most supported correlates for adolescents were land-use mix and residential density. These findings support several recommendations for policy and environmental change from such groups as the IOM and National Physical Activity Plan.
