Impact of Race and Ethnicity on Weight-Loss Outcomes in Pediatric Family-Based Obesity Treatment
Minority children are disproportionately affected by obesity and little is known about how race/ethnicity impacts outcomes in pediatric weight-loss treatment. This study aimed to evaluate whether race/ethnicity affected weight-loss outcomes in a pediatric obesity intervention. Secondary aims included evaluating whether race/ethnicity was associated with energy intake, exercise, program adherence, acceptability, and attendance.
One hundred fifty parent/child dyads (age 8–12 years, BMI% 85–99.9; 32% Hispanic, 24% Non-Hispanic, Non-White, 44% Non-Hispanic White) participated in a randomized control trial evaluating weight loss in family-based behavioral treatment with (FBT) or without child participation (i.e., Parent-Based Treatment, PBT). Assessments occurred at baseline, mid-treatment (month 3), post-treatment (month 6), and follow-up (months 12 and 24). Analyses included linear mixed effect models, linear models, and a negative binomial model.
Weight loss in Hispanic, Non-Hispanic White, and Non-Hispanic, Non-White children was not significantly different by race/ethnicity at months 6, 12, and 24 (p = 0.259) and was similar across both treatments (FBT = − 0.16 BMIz; PBT = − 0.21 BMIz; p = 0.61). There were no differences in energy intake, physical activity, acceptability ratings, or adherence to treatment (as measured by a post-treatment survey) (p’s > 0.123). However, Hispanic families attended fewer treatment visits than Non-Hispanic White families (p = 0.017).
On average, children lost weight participating in our pediatric obesity treatment and there was no statistical difference in weight loss between groups. Future research evaluating whether culturally adapted treatments would be more effective for racial/ethnic minorities or whether the personalization inherent in family-based behavioral treatment may be sufficient is needed.
