Racial/Ethnic Differences in the Effectiveness of a Multisector Childhood Obesity Prevention Intervention

Objectives: To investigate racial/ethnic and language differences in the effectiveness of the Massachusetts Childhood Obesity Research Demonstration (MA-CORD) study among children aged 2 to 4 years enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).
Methods: We performed a multisector quasiexperimental study in 2 MA-CORD intervention communities and 1 comparison community. Using WIC data from 2010 to 2015, we examined intervention effect on child weight and behavior outcomes by child race/ethnicity and parental primary language using multilevel linear regression models with an interaction term.
Results: Non-Hispanic Black children exposed to the intervention demonstrated a greater decrease in body mass index (BMI) than did other children (P < .05). Racial/ethnic minority children in the comparison site had greater increases in BMI than did their White counterparts (P < .05). There were no differences in intervention effectiveness by race/ethnicity or language for health behaviors.
Conclusions: White children demonstrated decreased BMI in both the intervention and control groups. However, intervention minority children demonstrated greater improvements in BMI than did control minority children.
Public Health Implications: To reduce racial/ethnic disparities, we need to disseminate effective obesity prevention interventions during early childhood in low-income settings.
