This randomized controlled trial tested a tailored, telephone-based physical activity coaching intervention for a predominantly African American group of women with severe obesity and mobility disability.
We recruited 92 clinic patients from the University of Illinois at Chicago Medical Center referred by their physicians during 2004-2007 and randomized participants to one of three groups--awareness(informational brochure, no coaching), lower support (phone coaching only) and higher support (phone coaching plus monthly exercise support group)--to determine the efficacy of a tailored coaching intervention on key health outcomes, which included body weight and body mass index, blood pressure, cholesterol, physical activity (barriers and self-reported activity), movement and mobility, general health, and social support.
The higher support group had the greatest reduction in Body Mass Index (BMI) (7.4%) compared with a 0.2% and 1.6% increase in BMI for the lower support and awareness groups, respectively (pb.01). Both the higher and lower support groups had a greater increase in physical activity scores (39% and 30%, respectively)compared with a decline of 13% in the awareness group (pb.05).
Providing phone-based coaching and monthly in-person exercise support group sessions appear to be an effective approach for reducing body weight and increasing physical activity among severely obese, disabled adults residing in difficult social environments.
本随机对照试验针对以非裔美国女性为主的严重肥胖且行动不便的人群，测试了一种基于电话的量身定制的体育活动指导干预措施。
我们从伊利诺伊大学芝加哥医学中心招募了92名在2004年至2007年期间由医生转诊的门诊患者，并将参与者随机分为三组——认知组（信息手册，无指导）、低支持组（仅电话指导）和高支持组（电话指导加每月一次的运动支持小组），以确定量身定制的指导干预措施对关键健康指标的效果，这些指标包括体重、体重指数、血压、胆固醇、体育活动（障碍和自我报告的活动）、运动和行动能力、总体健康状况以及社会支持。
高支持组的体重指数（BMI）下降幅度最大（7.4%），相比之下，低支持组和认知组的BMI分别增加了0.2%和1.6%（P<0.01）。高支持组和低支持组的体育活动得分增加幅度更大（分别为39%和30%），而认知组下降了13%（P<0.05）。
提供基于电话的指导和每月一次的面对面运动支持小组课程，似乎是一种有效的方法，可以降低生活在困难社会环境中的严重肥胖残疾成年人的体重并增加其体育活动量。
