Using CDC's Worksite Health ScoreCard to Evaluate Nutrition and Physical Activity Interventions in Priority Communities in New York State, 2015-2020.

The aim of our study was to evaluate a statewide obesity prevention program, designed to improve two social determinants of health (access to healthy foods and opportunities for physical activity) by changing worksite policies, systems, and environments. We used data on social determinants of health to identify priority communities and funded 25 contractors to recruit and engage worksites in those communities. We employed a pre/post quasi-experimental design and used the Centers for Disease Control and Prevention's Worksite Health ScoreCard to assess implementation of nutrition and physical activity strategies. Contractors collaborated with partners to conduct pre- and postassessments at 313 worksites. Worksites were successful at implementing all except one strategy; implementation doubled for eight strategies and tripled for three. We used weighted scores to incorporate strength of the evidence-base and level of impact into our analysis; increases in strategy implementation were statistically significant in worksites that provided places to purchase food and beverages and in those that did not. Our study revealed several important recommendations for practice. Use available data to prioritize communities experiencing health disparities and identify PSE change strategies to increase access to nutritious foods and physical activity opportunities. Engage with reputable community-based partners from different sectors when designing and implementing programs. Use standardized tools, such as the Worksite Health ScoreCard, to evaluate public health initiatives.

Nutrition Quality of US School Snack Foods: A First Look at 2011-2014 Bid Records in 8 School Districts.

BACKGROUND: As part of the Healthy, Hunger-Free Kids Act, snacks, and desserts sold in K-12 schools as of the 2014-2015 school year are required to meet the "Smart Snacks" nutritional guidelines. Although studies exist in tracking progress in local and national efforts, the proportion of snack food procured by school districts compliant with the Smart Snacks standard prior to its full implementation is unknown. METHODS: We repurposed a previously untapped database, Interflex, of public bid records to examine the nutritional quality of snacks and desserts procured by school districts. We selected 8 school districts with at least 90% complete data each year during 2011-2012, 2012-2013, and 2013-2014 school years and at locations across different regions of the United States. We quantified the amount of calories and sugar of each product contained in the won bids based on available online sources and determined whether the produce complied with Smart Snack guidelines. RESULTS: In all 8 districts (snack expenditure analyzed ranging from $152,000 to $4.4 million), at least 50% of snack bids were compliant with the US Department of Agriculture Smart Snacks standard during the 2013-2014 school year. Across sampled districts, we observed a general trend in lower caloric density (kcal per product) and sugar density (grams of sugar per product) over a 3-year period. CONCLUSIONS: Many districts across the country have made headway in complying with the Smart Snack guidelines, though gaps remain.

Effect of the Healthy Schools Program on prevalence of overweight and obesity in California schools, 2006-2012.

INTRODUCTION: The Alliance for a Healthier Generation's Healthy Schools Program (HSP) is a national evidence-based obesity-prevention initiative aimed at providing the schools in greatest need with onsite training and technical assistance (TTA) and consultation with national experts (HSP national advisors) to create sustainable healthy change in schools' nutrition and physical activity environments. The objective of this study was to evaluate the impact of HSP on the prevalence of overweight and obesity in California schools, from HSP's inception in 2006 through 2012. METHODS: We used statewide body mass index (BMI) data collected annually from 5th-, 7th-, and 9th-grade students to determine whether enrolling in the HSP's onsite intervention reduced the prevalence of overweight and obesity in intervention schools (n = 281) versus propensity-score matched control schools (n = 709) and whether increasing exposure to the program (TTA and contact with HSP national advisors) was associated with reductions in the prevalence of overweight and obesity. RESULTS: Analyses showed no difference between HSP schools and control schools in overweight or obesity prevalence. However, program exposure varied widely among participating schools, and each additional contact with TTA or HSP national advisors was associated with a 0.3% decline in overweight and obesity prevalence (P < .05). CONCLUSION: HSP appears to be an important means of supporting schools in reducing obesity. Although participation in HSP alone was not sufficient to improve weight status in California schools, there was a clear dose-response relationship to the program. HSP serves as an effective model for addressing childhood obesity among engaged schools.
