Review Comparative Study
Effects of physical activity interventions in youth. Review and synthesis.
Physical inactivity has been identified as an important public health concern for youth. School and community settings can be important infrastructures for promoting physical activity (PA). This paper reviews studies of physical activity in school and community settings among preschool through college-aged persons to determine characteristics and effects of interventions. Studies in progress are included. ⋯ The collection of school and community studies is limited for several age groups with none below third grade and only three at college age. There are few community studies. The most is known about upper-elementary-age-students, including the first multicenter randomized trial to report significant results for increasing moderate to vigorous physical activity (MVPA) in physical education (PE) and increase vigorous PA outside of school. A number of older study designs were weak and assessments less than optimal, but studies in progress are stronger. Special attention is needed for girls, middle schools, and community settings for all youth. More objective assessments are needed for measuring PA outside of school and in younger children, since they cannot provide reliable self-report.

Review Comparative Study
Physical activity interventions in low-income, ethnic minority, and populations with disability.
Low-income, racial and ethnic minority, and populations with disabilities are more likely to be sedentary than the general population. Increasing physical activity in these groups is an important public health challenge. This report summarizes interventions that have targeted populations at risk for inactivity. ⋯ Much work remains to develop effective interventions for these populations. Research that involves the community at all steps in the design and implementation of the intervention shows greatest promise for promoting behavior change. Future intervention studies should include: (1) rigorous experimental designs; (2) theoretically based interventions; and (3) validated assessment instruments to detect physical activity change.

Firearm-related injuries rank second only to motor vehicle-related injuries as a cause of injury death in Wisconsin. ⋯ With minimal resources and time, the Wisconsin Firearm-Related Injury Surveillance System uses existing state government databases to describe and report the burden of firearm-related injuries. Additional information on circumstances, perpetrators, and weapons involved are available but additional resources are needed to integrate this information with existing data.

Maryland began a statewide firearm-related injury surveillance system in 1995. The system now focuses on firearm-related deaths; a system to monitor nonfatal injuries is being developed. The system is passive; it accesses, integrates, and analyzes data collected by Maryland's Office of the Chief Medical Examiner, Maryland State Police, and Division of Health Statistics. ⋯ Maryland's database of information from the medical examiner's office is highly accurate for ascertaining firearm-related deaths that occur in the state. A unique identifier common across data sources would ease record linkage efforts, and improve the system's ability to monitor firearm-related deaths.

With the current progress of state firearm injury surveillance systems reported in this issue of the Journal, questions about the logical progression of these efforts are being raised. This article reviews the current state of firearm injury data, discusses the importance of firearm injury surveillance, and offers suggestions for maximizing the potential of future efforts in this area.
