Group versus individual phone-based obesity treatment for rural women

Rural women have among the highest rates of obesity and sedentary lifestyle, yet few studies have examined strategies for delivering state-of-the-art obesity treatment to hard-to-reach rural areas. The purpose of this pilot trial was to examine the impact and cost-effectiveness of a 6-month behavioral weight loss program delivered to rural women by phone either one-on-one with a counselor or to a group via conference call. Thirty-four rural women (mean BMI = 34.4, SD = 4.6) were randomized to group phone-based treatment or individual phone-based treatment. Completers analysis showed that weight loss was greater in the group condition (mean = 14.9 kg = , SD = 4.4) compared to the individual condition (mean = 9.5 kg, SD = 5.2; p = .03). Among the total sample, 62% of participants in the group condition achieved the 10% weight loss goal compared to 50% in the individual condition, and group treatment was found to be more cost-effective. Future research is warranted to examine the benefits of group phone-based treatment for long-term management of obesity among rural populations.
