Objective: Lifestyle variables such as drug use and excessive weight gain contribute to adult morbidity and mortality. This study was designed to determine whether participation in a preventive intervention designed to enhance supportive parenting can reduce drug use and body mass index (BMI) in young Black adults from disadvantaged neighborhoods.
Method: This study was conducted in the rural southeastern United States. Black parents and their 11-year-old children (517 families) were assigned randomly to the Strong African American Families (SAAF) prevention trial or a control condition. Data assessing neighborhood socioeconomic status and supportive parenting were obtained when the youths were ages 11 and 16. When youths were ages 19-21 and 25, drug use and BMI were measured.
Results: As hypothesized, significant three-way interactions were detected among neighborhood disadvantage, prevention condition, and gender for BMI (B = 3.341, p = .009, 95% CI [0.832, 5.849]) and substance use (B = -0.169, p = .049, 95% CI [-0.337, -0.001]). Living in a disadvantaged neighborhood during adolescence was associated with increased drug use among young men in the control group (simple-slope = 0.215, p < .003) but not among those in the SAAF condition (simple-slope = 0.030, p = .650). Neighborhood disadvantage was associated with elevated BMI among young women in the control group (simple-slope = 3.343, p < .001), but not in the SAAF condition (simple-slope = 0.204, p = .820).
Conclusions: The results suggest that participation during childhood in a preventive intervention to enhance supportive parenting can ameliorate the effects of life in a disadvantaged neighborhood on men's drug use and women's BMI across ages 19-25 years. These findings suggest a possible role for parenting enhancement programs in narrowing health disparities.
