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.

    The purpose of this study was to examine the associations between past and current maternal food insecurity and child-feeding practices among low-income Mexican-American families. Participants in the study were mother-child pairs enrolled in the Special Supplemental Nutrition Program for Women, Infants and Children (WIC). The findings suggest that low-income Mexican-American mothers who are currently experiencing food insecurity were more likely to worry that their children were eating too much food and tended to offer smaller portion sizes to their children than mothers not currently experiencing food insecurity. Mothers who were overweight were more than twice as likely to have overweight children than mothers who were not overweight.

      To curb the escalating rates of obesity in California and across the nation, it is imperative to identify dietary behaviors that prevent excessive weight gain. Reports in the press are often conflicting and more often confuse than clarify the issue of what people should eat to prevent obesity. We recently conducted a comprehensive review of the literature published between 1992 and 2003 on the dietary determinants of obesity in children and adults. We examined secular trend data, mechanistic research, observational studies and prevention trials. We found that the dietary factors related to increased obesity were high intakes of dietary fat, sweetened beverages and restaurant-prepared foods, and the increased likelihood of skipping breakfast. Factors most likely to protect against obesity were the higher consumption of dietary fiber, fruits and vegetables, calcium and dairy products.
