Interventionist-Guided Weight Loss Program for African American Breast Cancer Survivors

Key Points

  • Mean weight loss was 3.6% vs 1.4% at 6 months and 2.6% vs 1.6% at 12 months with an interventionist-guided weight loss program vs a self-guided weight loss program.
  • Weight loss > 5% was achieved by 44% vs 19%.

As reported by Stolley et al in the Journal of Clinical Oncology, a community-based interventionist-guided weight loss program for African American breast cancer survivors (Moving Forward) proved successful in achieving weight loss goals compared with a self-guided weight loss program. African American women with breast cancer have higher cancer-specific and overall mortality and a high prevalence of obesity that contributes to breast cancer progression and chronic health conditions.

Study Details

The study included 246 women with stage I to III disease and body mass index (BMI) ≥ 25 kg/m2 from Chicago-area cancer centers and community-based efforts who were randomized to an interventionist-guided weight loss initiative targeting weight, body composition, and behavior (n = 125) or a self-guided weight loss program supporting behavioral changes (n = 121) to promote ≥ 5% weight loss. Patients had a mean age of 58 years, mean BMI was 36.1 kg/m2, and 82% had stage I or II disease.

Weight Loss

For the interventionist-guided vs self-guided groups, mean absolute and percentage weight loss were 3.5 kg vs 1.3 kg (P < .001) and 3.6% vs 1.4% (P < .001) at 6 months and 2.7 kg vs 1.6 kg (P < .05) and 2.6% vs 1.6% (P < .05) at 12 months. Overall, ≥ 5% weight loss was achieved in 44% vs 19%. Beneficial body composition and behavioral changes were also greater in the interventionist-guided group at 6 and 12 months.

The investigators concluded: “The study supports the efficacy of a community-based interventionist-guided weight loss program targeting [African American breast cancer survivors]. Although mean weight loss did not reach the targeted 5%, the mean loss of > 3% at 6 months is associated with improved health outcomes. Affordable, accessible health promotion programs represent a critical resource for [African American breast cancer survivors].”

The study was supported by the National Cancer Institute.
