BACKGROUND: Few intervention studies have integrated cultural tailoring, parenting, behavioral, and motivational strategies to address African American adolescent weight loss. PURPOSE: The families improving together (FIT) for weight loss trial was a randomized group cohort study testing the efficacy of a cultural tailoring, positive parenting, and motivational intervention for weight loss in overweight African American adolescents (N = 241 adolescent/caregiver dyads). METHODS: The trial tested an 8-week face-to-face group motivational plus family weight loss program (M plus FWL) compared with a comprehensive health education control program. Participants were then rerandomized to an 8-week tailored or control online program to test the added effects of the online intervention on reducing body mass index and improving physical activity (moderate-to-vigorous physical activity (MVPA), light physical activity (LPA)), and diet. RESULTS: There were no significant intervention effects for body mass index or diet. There was a significant effect of the group M plus FWL intervention on parent LPA at 16 weeks (B 33.017, SE 13.115, p = 0.012). Parents in the group M plus FWL intervention showed an increase in LPA, whereas parents in the comprehensive health education group showed a decrease in LPA. Secondary analyses using complier average causal effects showed a significant intervention effect at 16 weeks for parents on MVPA and a similar trend for adolescents. CONCLUSIONS: While the intervention showed some impact on physical activity, additional strategies are needed to impact weight loss among overweight African American adolescents.
