Promoting weight‐loss maintenance among Black women primary care patients: A cluster RCT of a culturally sensitive versus standard behavioural approach

Summary The prevalence of obesity is higher among Black women (56.6%) compared to Hispanic women (50%) and non‐Hispanic White women (42%). Notably, interventions to reduce obesity typically result in initial weight loss that is not maintained. This study tested (a) the effectiveness of a 6‐month Health‐Smart Weight Loss (HSWL) Program for Black women patients with obesity implemented by community health workers (CHWs) within primary care clinics and (b) the comparative effectiveness of two 12‐month physician‐implemented weight loss maintenance programs—a Patient‐Centred Culturally Sensitive Weight Loss Maintenance Program (PCCS‐WLM Program) and a Standard Behavioural Weight Loss Maintenance Program (SB‐WLM Program). Black women patients (N = 683) with obesity from 20 community primary care clinics participated in the HSWL Program and were then randomized to either maintenance program. The HSWL Program led to significant weight loss (i.e., 2.7 pounds, 1.22 kg, p
