Review Meta Analysis
Text Message Interventions for Physical Activity: A Systematic Review and Meta-Analysis.
Despite clear health benefits, many individuals fail to achieve the recommended levels of physical activity. Text message interventions to promote physical activity hold promise owing to the ubiquity of cell phones and the low expense of text message delivery. ⋯ Text message interventions lead to higher objectively measured postintervention physical activity compared with control groups. More extensive, well-controlled studies are needed to examine this relationship further and identify characteristics of effective text message interventions.

Meta Analysis
Physical Activity and Anxiety: A Systematic Review and Meta-analysis of Prospective Cohort Studies.
Anxiety symptoms and disorders are highly prevalent and costly. Prospective studies suggest that physical activity may prevent anxiety development; however, this body of literature has not been reviewed comprehensively. ⋯ Available evidence suggests that engaging in physical activity protects against anxiety symptoms and disorders. However, notable challenges in the current evidence base include issues regarding exposure and outcome measures, consistent adjustment for putative confounders, representativeness of samples, and attrition bias, which warrant further research.

Meta Analysis
Sitting Time and Risk of Cardiovascular Disease and Diabetes: A Systematic Review and Meta-Analysis.
Whether physical activity attenuates the association of total daily sitting time with cardiovascular disease and diabetes incidence is unclear. This systematic review and meta-analysis examined the association of total daily sitting time with cardiovascular disease and diabetes with and without adjustment for physical activity. ⋯ Higher levels of total daily sitting time are associated with an increased risk of cardiovascular disease and diabetes, independent of physical activity. Reductions in total daily sitting may be recommended in public health guidelines.

Meta Analysis
Lay Advisor Interventions in Rural Populations: A Systematic Review and Meta-analysis.
Age-adjusted death rates for heart disease are higher in rural areas than in urban areas. Lay advisors could potentially facilitate improvement in cardiovascular health outcomes. The aim of this systematic review and meta-analysis is to estimate lay advisor intervention effects on cardiovascular health metrics in rural populations. ⋯ Lay advisor interventions had significant positive effects on glycemic control and BMI for rural residents; however, further rigorous studies are needed in U.S. rural populations, and elements of effective lay advisor interventions require further investigation.

Meta Analysis Comparative Study
Urban-Rural Differences in Older Adult Depression: A Systematic Review and Meta-analysis of Comparative Studies.
Depression among older adults (aged 60 years or older) is a problem that could be exacerbated by global trends in urbanization and population aging. The study purpose was to assess whether urban, relative to rural, residence is associated with depression among older adults and whether associations differ in countries with developed versus developing economies. ⋯ Converging trends of urbanization and population aging could increase the global burden of depression among older adults. The pathways through which urban-rural residence influences depression risk among older adults might differ by country context. Future research should focus on measuring variation in these contexts.
