A randomized controlled trial of culturally tailored dance and reducing screen time to prevent weight gain in low-income African American girls: Stanford GEMS.
OBJECTIVE To test a 2-year community- and family-based obesity prevention program for low-income African American girls : Stanford GEMS ( Girls ' health Enrichment Multi-site Studies ) . DESIGN R and omized controlled trial with follow-up measures scheduled at 6 , 12 , 18 , and 24 months . SETTING Low-income areas of Oakl and , California . PARTICIPANTS African American girls aged 8 to 10 years ( N=261 ) and their parents or guardians . INTERVENTIONS Families were r and omized to one of two 2-year , culturally tailored interventions : ( 1 ) after-school hip-hop , African , and step dance classes and a home/family-based intervention to reduce screen media use or ( 2 ) information-based health education . MAIN OUTCOME MEASURE Changes in body mass index ( BMI ) . RESULTS Changes in BMI did not differ between groups ( adjusted mean difference [ 95 % confidence interval ] = 0.04 [ -0.18 to 0.27 ] per year ) . Among secondary outcomes , fasting total cholesterol level ( adjusted mean difference , -3.49 [ 95 % confidence interval , -5.28 to -1.70 ] mg/dL per year ) , low-density lipoprotein cholesterol level ( -3.02 [ -4.74 to -1.31 ] mg/dL per year ) , incidence of hyperinsulinemia ( relative risk , 0.35 [ 0.13 to 0.93 ] ) , and depressive symptoms ( -0.21 [ -0.42 to -0.001 ] per year ) decreased more among girls in the dance and screen time reduction intervention . In exploratory moderator analysis , the dance and screen time reduction intervention slowed BMI gain more than health education among girls who watched more television at baseline ( P = .02 ) and /or those whose parents or guardians were unmarried ( P = .01 ) . CONCLUSIONS A culturally tailored after-school dance and screen time reduction intervention for low-income , preadolescent African American girls did not significantly reduce BMI gain compared with health education but did produce potentially clinical ly important reductions in lipid levels , hyperinsulinemia , and depressive symptoms . There was also evidence for greater effectiveness in high-risk subgroups of girls
