The Special Supplemental Nutrition Program for Women, Infants and Children (WIC) required major revisions to food packages in 2009; effects on nationwide low-income household purchases remain unexamined. ⋯ WIC food package revisions appear associated with improved nutritional profiles of food purchases among WIC participating households compared with low-income nonparticipating households. These package revisions may encourage WIC families to make healthier choices among their overall packaged food purchases.

Bicycling is a health-promoting physical activity, but little is known about the factors that influence this behavior in the U.S. The objective of this cross-sectional study was to identify multilevel ecologic correlates of bicycling behaviors in a nationally representative sample of U.S. adults. ⋯ In the U.S., recreation bicycling is a choice-based behavior, whereas transportation bicycling may be more influenced by the perceived and objective built environment. Interventions should consider how to make recreation and transportation bicycling more accessible and affordable to all individuals.

Rising rates of childhood obesity over the past 2 decades have spurred a number of public- and private-sector initiatives aimed at halting or even reversing this trend. Recognizing common interests in this issue, the Centers for Disease Control and Prevention, NIH, and the Robert Wood Johnson Foundation began conversations about creating a formal collaboration aimed at accelerating efforts to address childhood obesity by coordinating research agendas and providing support for evidence-building activities. The National Collaborative on Childhood Obesity Research (NCCOR) was launched in February 2009, and the U. ⋯ Department of Agriculture joined in 2010. Using the model provided by other previously successful collaborations, such as the Youth Tobacco Cessation Collaborative, NCCOR has emphasized several principles suggested by Petrovich as key elements for successful partnerships: (1) delineate a common purpose by identifying key knowledge gaps in the field; (2) create a shared identity around that common purpose; (3) develop structures for democratic and respectful collaboration so as to strategically coordinate efforts for maximum national impact; (4) identify effective leaders capable of articulating challenges in the field and inspiring a commitment of minds and the resolve to address identified needs; (5) facilitate continuous knowledge exchange and synthesis to keep the field informed; and (6) support assessment of progress and feedback loops for ensuring continual progress. This paper examines how NCCOR has used these principles to help build the field of research, evaluation, and surveillance for childhood obesity prevention and management.

Crime and safety are often cited as potential hurdles to park use and park-based physical activity. Using comprehensive data sources including both objective and subjective measurements at the park level and the individual level, this study aimed to assess the association between crime rates and use of local parks in low-income urban neighborhoods. ⋯ Gun-related violent crimes have relatively long-term negative associations with population health by reducing utilization of outdoor park space. There can be additional population health benefits from controlling and reducing gun-related violent crimes beyond immediate impacts on public safety and mortality.

The purpose of this study is to reconcile public health workforce supply and demand data to understand whether the expected influx of public health graduates can meet turnover events. ⋯ Demands for public health staff could possibly be met by the influx of graduates from schools and programs of public health. However, substantial implications exist for transferal of institutional knowledge and ability to recruit and retain the best staff to sufficiently meet demand.
