Behavioral treatment for weight gain prevention among black women in primary care practice: a randomized clinical trial.
IMPORTANCE Few weight loss treatments produce clinical ly meaningful weight loss outcomes among black women , particularly in the primary care setting . New weight management strategies are necessary for this population . Weight gain prevention might be an effective treatment option , with particular benefits for overweight and class 1 obese black women . OBJECTIVE To compare changes in weight and cardiometabolic risk during a 12-month period among black women r and omized to a primary care-based behavioral weight gain prevention intervention , relative to usual care . DESIGN , SETTING , AND PARTICIPANTS Two-arm r and omized clinical trial ( the Shape Program ) . We recruited patients from a 6-site community health center system . We r and omized 194 overweight and class 1 obese ( body mass index [ calculated as weight in kilograms divided by height in meters squared ] , 25 - 34.9 ) premenopausal black women aged 25 to 44 years . Enrollment began on December 7 , 2009 ; 12- and 18-month assessment s were completed in February and October 2 , 2012 . INTERVENTIONS The medium-intensity intervention included tailored behavior change goals , weekly self-monitoring via interactive voice response , monthly counseling calls , tailored skills training material s , and a gym membership . MAIN OUTCOMES AND MEASURES Twelve-month change in weight and body mass index and maintenance of change at 18 months . RESULTS Participants had a mean age of 35.4 years , a mean weight of 81.1 kg , and a mean body mass index of 30.2 at baseline . Most were socioeconomically disadvantaged ( 79.7 % with educational level less than a college degree ; 74.3 % reporting annual income < $ 30,000 ) . The 12-month weight change was larger among intervention participants ( mean [ SD ] , -1.0 [ 0.5 ] kg ) , relative to usual care ( 0.5 [ 0.5 ] kg ; mean difference , -1.4 kg [ 95 % CI , -2.8 to -0.1 kg ] ; P = .04 ) . At month 12 , 62 % of intervention participants were at or below their baseline weights compared with 45 % of usual-care participants ( P = .03 ) . By 18 months , intervention participants maintained significantly larger changes in weight ( mean difference , -1.7 kg ; 95 % CI , -3.3 to -0.2 kg ) . CONCLUSIONS AND RELEVANCE A medium-intensity primary care-based behavioral intervention demonstrated efficacy for weight gain prevention among socioeconomically disadvantaged black women . A " maintain , do n't gain " approach might be a useful alternative treatment for reducing obesity-associated disease risk among some premenopausal black women .
