Meta Analysis
Physical Activity Levels and New Public Transit: A Systematic Review and Meta-analysis.
Physical inactivity is a public health concern as it contributes to the rising burden of noncommunicable diseases. Introducing new public transportation options, such as extending or building new light rail or bus rapid transit stations, could encourage commuters to walk to and from public transit stops, thus increasing their physical activity levels. Despite previous research generally finding positive associations between public transit usage and physical activity levels, few have summarized the association between introducing new public transportation options and different intensities of physical activity. This study aimed to systematically review the current evidence and perform a meta-analysis on this association. ⋯ Results show new public transit options can substantially contribute to increasing low- to moderate-intensity exercise levels, which has the potential to improve health on a population scale.

Local Wellness Policies are school-district documents containing guidelines for schools to promote nutrition/physical activity. In cross-sectional studies, schools with wellness committees are more likely to implement Local Wellness Policies. This prospective cohort study examines associations between wellness committee status over time and change in Local Wellness Policy implementation using a biennial, statewide survey. ⋯ Forming and maintaining wellness committees encourages Local Wellness Policy implementation and should be a recommended strategy for school wellness promotion.

Observational Study
Change in Children's Physical Activity: Predictors in the Transition From Elementary to Middle School.
Interventions to promote physical activity in children should be informed by knowledge of the factors that influence physical activity behavior during critical developmental transitions. The purpose of this study is to identify, from a comprehensive, multidomain set of factors, those that are associated with change in objectively measured physical activity in children as they transition from elementary to middle school. ⋯ Interventions designed to increase children's physical activity should include strategies that target multiple domains of influence.

The purpose of this study is to determine the effectiveness of a patient-centered medical home intervention for teen parent families in reducing rates of unintended repeat pregnancy in the first 2 years postpartum. ⋯ This comprehensive and integrated model of care for teen parents may be an effective method to prevent rapid repeat pregnancies in this vulnerable population.

Comparative Study
A National Comparison of Suicide Among Medicaid and Non-Medicaid Youth.
In the U.S., youth enrolled in Medicaid experience more risk factors for suicide, such as mental illness, than youth not enrolled in Medicaid. To inform a national suicide prevention strategy, this study presents suicide rates in a sample of youth enrolled in Medicaid and compares them with rates in the non-Medicaid population. ⋯ The population-based profile of suicide among youth enrolled in Medicaid differs from the profile of youth not enrolled in Medicaid, confirming the importance of Medicaid as a "boundaried" suicide prevention setting.
