MONDAY, Aug. 26 (HealthDay News) -- A medium-intensity behavioral intervention that focuses on maintaining rather than losing weight is effective for preventing weight gain among overweight and obese black women, according to a study published online Aug. 26 in JAMA Internal Medicine.
Gary G. Bennett, Ph.D., from Duke University in Durham, N.C., and colleagues randomly assigned 194 overweight and class 1 obese (body mass index, 25 to 34.9 kg/m²) black women 25 to 44 years old to a primary care-based behavioral weight gain prevention intervention (behavioral changes, self-monitoring, counseling, skills training, and a gym membership) or usual care.
At 12 months, the researchers found that the intervention group had a significantly greater weight change compared to the usual-care group. Significantly more women in the intervention group were at or below their baseline weights at 12 months (62 versus 45 percent). At 18 months, the intervention group maintained significantly larger changes in weight.
"A medium-intensity primary care-based behavioral intervention demonstrated efficacy for weight gain prevention among socioeconomically disadvantaged black women," Bennett and colleagues conclude.
