Abstract
There is a need to disseminate evidence-based childhood obesity prevention interventions on a broader scale to reduce obesity-related disparities among underserved children. The purpose of this study was to test the comparative effectiveness of an evidence-based obesity prevention intervention, Hip-Hop to Health (HH), delivered through Expanded Food and Nutrition Education Program (EFNEP) and the Supplemental Nutrition Assistance Program-Education (SNAP-Ed) versus the standard curriculum delivered by the programs (Standard Nutrition Education (NE)). A nonequivalent control group design was delivered to compare the effectiveness of HH to NE on weight gain prevention and health behavior outcomes at EFNEP and SNAP-Ed sites. One hundred and fifty-three caregiver–child dyads (n = 103 in the HH group; n = 50 in the NE group) participated in the study. HH is an evidence-based dietary and physical activity intervention for low-income preschool children. The NE curriculum provided lessons for children that are consistent with the Dietary Guidelines for Americans 2010. Data were collected on demographics, anthropometrics, and behavioral variables for parent–child dyads at baseline and postintervention. Mixed model methods with random effects for site and participant were utilized. No differences in child or caregiver diet, physical activity, or screen time by group were found. No between-group differences in child BMI z-score were found; however, caregivers in the HH group lost significantly more weight than those in the NE group. Results from this trial can inform future dissemination efforts of evidenced-based programs for underserved families.

Parent–child dyads in HH received an eight-lesson obesity prevention intervention that was delivered over 6–8 weeks
Summary
Obesity is an epidemic in the US, [1,2,3] and increases risk for comorbidities such as heart disease, diabetes, and some cancers [4]. In 2016, 13.9% of US preschool-aged children were obese [5]. Patterns of obesogenic behavior initiated in early childhood are linked to behaviors in adulthood, and lead to poor health outcomes [6,7,8]. Rates of obesity are higher among minority children. In 2013–2016, 9.9% of Non-Hispanic White, 11.6% of Non-Hispanic Black, and 16.5% of Hispanic preschool children were obese. Prevalence rates increased by age; for example the prevalence rate of obesity was higher among
