ReviewImplementation of school based physical activity interventions: a systematic review.
Implementation science is an emerging area in physical activity (PA) research. We sought to establish the current state of the evidence related to implementation of school-based PA models to explore 1) the relationship between implementation and health outcomes, and 2) factors that influence implementation. ⋯ Implementation evaluation supports scale-up of effective school-based PA interventions and thus population-level change. Our review serves as a call to action to 1) address the link between implementation and outcome within the school-based PA literature and 2) improve and standardize definitions and measurement of implementation.

Does social support mediate the relationship among neighborhood disadvantage, incivilities, crime and physical activity?
Neighborhood disadvantage (ND), incivilities, and crime disproportionately impact minority women, discouraging physical activity (PA). Social support (SS) is a cultural tool promoting PA in minority women. Socially supportive environments may promote PA in disadvantaged neighborhoods, yet few studies have investigated the mediating role of social support among minority women. This study examined SS as a mediator among ND, incivilities, crime, and PA. ⋯ ND significantly discourages PA and limits SS. Future research should focus on developing strategies to overcoming these negative environmental factors.

The association of physical activity with all-cause, cardiovascular, and cancer mortalities among older adults.
To evaluate the association of physical activity with all-cause, cardiovascular, and cancer mortalities among older adults. ⋯ Physical activity had an inverse association with all-cause, cardiovascular, and cancer mortality among older adults. Furthermore, most elderly people can benefit from an active lifestyle.

U.S. adults and child snacking patterns among sugar-sweetened beverage drinkers and non-drinkers.
To provide national estimates of snack patterns for sugar-sweetened beverage (SSB) drinkers and non-SSB drinkers among U.S. children and adults. ⋯ Adults and children who drink SSBs are more likely to snack and consume more calories from snacks than non-SSB drinkers, particularly Black adolescents and young adults.
