State-Specific Prevalence of Obesity Among Children Aged 2-4 Years Enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children - United States, 2010-2016.

Obesity negatively affects children's health because of its associations with cardiovascular disease risk factors, type 2 diabetes, asthma, fatty liver disease, victimization stemming from social stigma and bullying, and poor mental health (e.g., anxiety and depression) (1). Children who have overweight or obesity in early childhood are approximately four times as likely to have overweight or obesity in young adulthood as their normal weight peers (2). Obesity prevalence is especially high among children from low-income families (3). In 2010, the overall upward trend in obesity prevalence turned downward among children aged 2-4 years enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), a program of the U.S. Department of Agriculture (USDA); prevalence decreased significantly in all racial/ethnic groups and in 34 of the 56 WIC state or territory agencies during 2010-2014 (4). A more recent study among young children enrolled in WIC reported that the overall obesity prevalence decreased from 15.9% in 2010 to 13.9% in 2016 and statistically significant decreases were observed in all age, sex, and racial/ethnic subgroups (3). However, this study did not provide obesity trends at the state level. In collaboration with USDA, CDC used data from the WIC Participant and Program Characteristics (WIC PC) to update state-specific trends through 2016. During 2010-2016, modest but statistically significant decreases in obesity prevalence among children aged 2-4 years enrolled in WIC occurred in 41 (73%) of 56 WIC state or territory agencies. Comprehensive approaches that create positive changes to promote healthy eating and physical activity for young children from all income levels,* strengthen nutrition education and breastfeeding support among young children enrolled in WIC, and encourage redemptions of healthy foods in WIC food packages could help maintain or accelerate these declining trends.

The Impact of Federal Policy Changes and Initiatives on Breastfeeding Initiation Rates and Attitudes Toward Breastfeeding Among WIC Participants.

To explore the effects of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on participants' breastfeeding (BF) practices, studies that use large national samples are warranted. The US Department of Agriculture's Food and Nutrition Service funded several studies that leveraged national samples of WIC agencies, sites, and participants to evaluate how WIC affects BF outcomes among its participants. This report integrates findings across multiple Food and Nutrition Service-funded studies to describe important program benefits and how the program and its benefits supported positive attitudes and beliefs toward BF, as well as higher rates of BF initiation. The report concludes with policy implications and suggestions for future research.

Statewide evaluation of local wellness policies in Georgia: an examination of policy compliance, policy strength, and associated factors.

OBJECTIVE: To analyze relationships between demographic characteristics of Georgia school systems and: (1) compliance with the Child Nutrition and WIC Reauthorization Act (CNRA); and (2) strength of wellness policy goals in nutrition, physical activity, and other school-based activities. DESIGN: Each local school district submitted their school-board-approved wellness policy to researchers. Each policy was reviewed and coded for compliance with CNRA and evaluated on the strength of its goals. SETTING: Public school districts. PARTICIPANTS: One hundred seventy-six of 180 Georgia public school systems participated. MAIN OUTCOME MEASURES: Independent variables were demographic characteristics of Georgia school systems. Dependent variables were ratings from the policy evaluation instrument, grouped into composite indices to compare the strength (ie, ratings) of wellness policy goals. ANALYSIS: Pearson correlation, cross-tabulation. RESULTS: Significant positive associations were found between academic performance and: strength of overall wellness policy goals (P < .05), goals in nutrition education (P < .01), and other school-based activities (P < .01). Economic status of the student population was found to be positively associated with strength of nutrition education goals (P < .05). CONCLUSIONS AND IMPLICATIONS: Districts with stronger academic performance had more comprehensive overall wellness policy goals and stronger goals in nutrition education and other school-based activities.
