A Systematic Review of the Impact of Juvenile Curfew Laws on Public Health and Justice Outcomes.
Automobile crashes cause more than 800,000 youth injuries and deaths each year. Other youth suffer the consequences from being either a perpetrator or victim of a crime. One type of law that has an effect on youth behavior is juvenile curfew laws. These laws restrict the times that youth may occupy public places or streets. We systematically reviewed studies evaluating the effectiveness of these laws to address the question: Can juvenile curfew laws be used to improve youth public health and juvenile justice outcomes? ⋯ The studies that found that juvenile curfew laws were effective at reducing adverse youth health outcomes (e.g., trauma transports); juvenile crime; and victimization were of higher quality (e.g., stronger methodologic approaches) than those finding no effects. However, given the limited number of studies and concerns with quality, we conclude that more research is needed before conclusions can be drawn about the effectiveness of juvenile curfew laws.

TV viewing is the most prevalent sedentary behavior and is associated with increased risk of cardiovascular disease and cancer mortality, but the association with other leading causes of death is unknown. This study examined the association between TV viewing and leading causes of death in the U.S. ⋯ This study shows the breadth of mortality outcomes associated with prolonged TV viewing, and identifies novel associations for several leading causes of death. TV viewing is a prevalent discretionary behavior that may be a more important target for public health intervention than previously recognized.

Muscle strength preservation may play an important role in protecting against cardiometabolic diseases, functional decline, musculoskeletal deterioration, and early all-cause mortality. However, sex-specific strength growth charts and curves using data from a U.S.-representative sample and clinically feasible measurement remain to be established. ⋯ The established strength quantiles can easily be incorporated into a clinical setting for screening individuals that would benefit from lifestyle interventions to improve muscular fitness and reduce health risks.
