The White House Task Force on Childhood Obesity has set a goal of increasing walking and biking to school by 50% within 5 years. Meeting the goal requires a detailed understanding of the current patterns of school travel. ⋯ There have been sharp increases in driving children to school since 1969 and corresponding decreases in walking to school. This increase is particularly evident in the number of vehicle trips generated by parents dropping children at school and teens driving themselves. The NHTS survey provides a unique opportunity to monitor these trends in the future.

A recent systematic review of home-based, multi-trigger, multicomponent interventions with an environmental focus showed their effectiveness in reducing asthma morbidity among children and adolescents. These interventions included home visits by trained personnel to assess the level of and reduce adverse effects of indoor environmental pollutants, and educate households with an asthma client to reduce exposure to asthma triggers. The purpose of the present review is to identify economic values of these interventions and present ranges for the main economic outcomes (e.g., program costs, benefit-cost ratios, and incremental cost-effectiveness ratios). ⋯ The benefits from home-based, multi-trigger, multicomponent interventions with an environmental focus can match or even exceed their program costs. Based on cost-benefit and cost-effectiveness studies, the results of this review show that these programs provide a good value for dollars spent on the interventions.

Recent epidemiologic evidence points to the health risks of prolonged sitting, that are independent of physical activity, but few papers have reported the descriptive epidemiology of sitting in population studies with adults. ⋯ Median sitting time varied widely across countries. Assessing sitting time is an important new area for preventive medicine, in addition to assessing physical activity and sedentary behaviors. Population surveys that monitor lifestyle behaviors should add measures of sitting time to physical activity surveillance. Moreover, the use of objective measures to capture the spectrum of sedentary (sitting) and physical activity behaviors is encouraged, particularly in low- and middle-income countries commencing new surveillance activities.

Public health services and systems research (PHSSR) focuses on the structure, organization, and legal basis of domestic public health activities and their effect on population health. An accurate description of the field is needed to empower funding agencies and other stakeholders to coordinate PHSSR activities and to foster the development of the field. The purpose of the study is to characterize the emerging community of researchers engaged in PHSSR. This study (1) describes dynamics of this growing community and (2) identifies research themes, subgroups within the field, and collaboration among groups. ⋯ Although a nucleus group of productive and engaged individuals participate in PHSSR, most also publish broadly on health services research and population health. This trend suggests that this emerging field cannot yet support a singular focus on PHSSR. Lack of funding sources and defined career paths likely contribute to this pattern. An overview of collaboration in PHSSR is an important step in advancing a coordinated research agenda and attracting sustainable funding streams for this field.

As the prevalence of childhood obesity has risen in past decades, more attention has been given to how the neighborhood food environment affects children's health outcomes. ⋯ Although food store inventories were not assessed and food store indices were not created, the availability of neighborhood food stores may affect a young girl's weight trajectory over time.
