Food Insecurity Linked to Nutrition Problems Among Children of Mexican-Origin
Researchers at the Texas A&M University PRC are the first to conduct a study using self-reported data from children of Mexican-origin (ages 6-11 years) living in colonias, Texas-Mexico border communities, to assess the relationship between food insecurity experiences and dietary intake. The findings showed an association between food access and nutritional health. As access to food declined, researchers found that children consumed more total calories and calories from fats, and sugars. Researchers will continue to examine ways to reduce food insecurity in colonias, through federal and community food and nutrition assistance programs. See “Children’s very low food security is associated with increased dietary intakes in energy, fat, and added sugar among Mexican-origin children (6-11 y) in Texas border ColoniasExternal Web Site Icon,” published online February, 20, 2012 in BioMed Central Pediatrics.
Framework Developed to Evaluate Obesity Prevention Policy Interventions
Researchers at the CDC-funded Center of Excellence for Training and Research Translation (Center TRT), based in the University of North Carolina at Chapel Hill PRC, have developed a framework for public health practitioners to evaluate public policy initiatives at the state and local level.  The framework is based on the use of logic models that evolve as the project progresses and the model has four standard sections: inputs, activities, outputs, and outcomes. Public health practitioners can use the Center TRT framework to identify and adapt components of obesity prevention policy approaches to fit their needs. See “An Evaluation Framework for Obesity Prevention Policy Interventions,” released June 28, 2012, by Preventing Chronic Disease.
Researchers Evaluate Implementation Tools to Improve Population Health
St. Louis University and Washington University in St. Louis PRC researchers have examined several tools for implementing evidence-based programs and policies that provide public health practitioners with the needed knowledge and skills to perform their work and improve population health. Researchers discovered that many implementation tools efficiently integrate the best available evidence and strategies to help practitioners understand evidence-based public health, evaluate interventions not yet proved, strengthen polices and improve practice, and engage in decision making with others. To find out what implementation tools were evaluated, such as Cancer Control P.L.A.N.E.T. and The Community Tool Box, and learn more, see "Tools for Implementing an Evidence-Based Approach in Public Health Practice," released June 21, 2012, by Preventing Chronic Disease.
PRC Network Produces Journal Supplement on Nutrition Policy Research
The work of the PRC Program’s Nutrition and Obesity Policy Research and Evaluation NetworkExternal Web Site Icon (NOPREN) is the focus of the September 2012 supplement of the American Journal of Preventive Medicine (AJPM). The supplement examines policies for promoting healthy eating and reducing consumption of sugar-sweetened beverages. The supplement features discussions and findings from PRC researchers on the following topics:
  • Implementation costs of providing free drinking water in Massachusetts public schools
  • Product assortment in south Texas convenience stores
  • The New Orleans Fresh Food Retailer Initiative
  • Water availability during snack time in after-school programs
  • Obesity-themed policy briefs
See Research in Brief for a description of each article. NOPREN is funded by CDC’s Division of Nutrition, Physical Activity and Obesity to describe and study the effectiveness of policies intended to create environments that support healthy food and beverage choices.

Researchers Evaluate Telephone-Based Physical Activity Program for Older Adults
University of Washington PRC researchers have determined that the Physical Activity for a Lifetime of Success (PALS) program is effective in increasing the activity levels among sedentary older adults, specifically in the areas of aerobic endurance, strength, and flexibility. In interviews of participants and people who declined to participate, the telephone-based delivery of the program was identified as a deterrent among nonjoiners and was not well-received by participants. Researchers continue to explore other ways to reach diverse, low-income older adult populations. See "Evaluation of a Telephone-based Physical Activity Promotion Program for Disadvantaged Older Adults," released February 23, 2012, by Preventing Chronic Disease.

Study Shows Changes to Built Environment in Low-Income Black Neighborhoods May Increase Physical Activity
Tulane University PRC researchers evaluated the effect of a walking path and school playground on physical activity in a low-income African-American neighborhood of New Orleans. By analyzing data from direct observation and surveys of residents, the researchers measured physical activity levels in this neighborhood and two comparison neighborhoods before and after the path and playground were built. The findings showed the proportion of residents observed to be active increased significantly in the neighborhood section with the path compared with the comparison neighborhoods. The increased activity was observed in the intervention area, not on the path itself, as the path led to a park with recreational facilities. No significant increase in physical activity was observed in the neighborhood section with the playground. The findings suggest that walking paths or trails may hold potential for increasing physical activity in low-income neighborhoods. See "Effect of Changes to the Neighborhood Built Environment on Physical Activity in a Low-Income African American Neighborhood" in the February 16, 2012, issue of Preventing Chronic Disease.

Researchers Analyze Price and Healthfulness of Snacks in After-School Programs
In assessing snacks served at YMCA after-school programs, Harvard University PRC researchers found that healthful snacks were typically more expensive than less healthful options. Consequently the researchers identified ways that healthful snacks can be served at or below the prices of less healthful options. See "Price and Healthfulness of Snacks in 32 YMCA After-School Programs in 4 U.S. Metropolitan Areas, 2006–2008," released January 12, 2012, by Preventing Chronic Disease.
Study Finds Training of Employment Program Staff Increased Mental Health Discussions and Referrals
Researchers at the Johns Hopkins University PRC analyzed data from inexpensive 2-day mental health training of staff at an employment training program for out-of-school youth. They found that the training increased the percentage (from 1% to 9%) of participants who had a mental health discussion with youth employment trainers. They also found that the training increased the percentage (from 11% to 16%) of participants who received a referral to mental health services from youth employment trainers. See “Training of Staff of an Employment Training Program to Promote Mental Health Discussions and Referrals with Out-of-School Youth, Baltimore, Maryland, 2007,” released January 26, 2012, by Preventing Chronic Disease.
