OBJECTIVES: This study tested the efficacy of an 8-week, culturally targeted community-based nutrition and physical activity promotion intervention, Fight Cancer with Fitness! (FCF). METHODS: A randomized, controlled trial was conducted in a black-owned commercial gym in a sample of 366 predominantly overweight or obese, healthy African-American women. RESULTS: Dietary quality as indexed by fruit and vegetable intake improved significantly in the intervention group compared to the control group at 12-month follow-up, and proportion of calories consumed as fat decreased in both groups. CONCLUSIONS: This individually targeted cancer prevention intervention produced beneficial effects on dietary quality that were sustained for at least 12 months.
