DESCRIPTION (provided by applicant): Morbidity and mortality risks for chronic conditions such as cardiovascular disease, diabetes, hypertension, and stroke associated with overweight/obesity, physical inactivity, and unhealthy diets are higher in minority and economically disadvantaged women, who also tend to have poorer diet and physical activity behaviors compared to the general population. This study takes a comprehensive approach to behavior change that gives attention to individual attitudes and skills, sociocultural factors, and environmental factors influencing behavior change. The study's primary aim is to test the effects of 16 weeks of a culturally-appropriate, behavioral/social support lifestyle intervention (one counseling session and 16 weekly group sessions) on body weight, body mass index, and waist circumference, compared to a usual-care, minimal-contact control group (one counseling session) among overweight or obese women of lower income. The goal of the intervention is for the women (ages 25 to 50) to achieve a 10% reduction in weight at a rate of one to two pounds per week. Secondary aims are to: a) test the effects of the 16-week intervention on physical fitness, physical activity level, total energy intake, % caloric intake from total fat, saturated fat, and trans fat, fruit and vegetable intake, self-efficacy for diet and physical activity, social support for diet and physical activity, and behavioral skills for healthy diet and physical activity; b) test the effects of 8 weeks of a telephone-contact maintenance intervention on primary and secondary outcomes; and c) assess long-term maintenance of primary and secondary outcomes 18 weeks after the end of the maintenance intervention phase. Pre-intervention activities will include focus groups to insure cultural sensitivity of the intervention. A community advisory board will advise on recruitment, logistics, and cultural appropriateness. This community-based, randomized controlled trial will include 90 women in the intervention group and 90 in a "usual care" control group. Objective and self-report measures will be taken at four time points: baseline, immediate posttest after 16 weeks of intervention, delayed posttest after an additional 8 weeks of the telephone-contact maintenance intervention, and a follow-up posttest. To enhance community acceptability of the research, the control group will be offered the intervention after all measures are completed.

描述（由申请人提供）：与超重/肥胖、缺乏身体活动和不健康饮食相关的慢性疾病（如心血管疾病、糖尿病、高血压和中风）的发病率和死亡风险在少数族裔和经济弱势女性中较高，与一般人群相比，她们的饮食和身体活动行为也往往较差。本研究采用综合方法来研究行为改变，关注个人态度和技能、社会文化因素以及影响行为改变的环境因素。该研究的主要目的是测试为期 16 周的文化适宜的行为/社会支持生活方式干预（一次咨询课程和每周 16 次小组课程）对体重、体重指数和腰围的影响，并与常规护理、最少接触的对照组（一次咨询课程）相比，对超重或肥胖的低收入女性进行比较。干预的目标是让女性（25 至 50 岁）以每周 1 至 2 磅的速度减少 10% 的体重。次要目标是： a) 测试 16 周干预对身体健康、身体活动水平、总能量摄入、总脂肪、饱和脂肪和反式脂肪的热量摄入百分比、水果和蔬菜摄入量、饮食和身体活动的自我效能、饮食和身体活动的社会支持以及健康饮食和身体活动的行为技能的影响； b) 测试 8 周的电话联系维护干预对主要和次要结果的影响； c) 在维持干预阶段结束后 18 周评估主要和次要结果的长期维持。干预前活动将包括焦点小组，以确保干预的文化敏感性。社区咨询委员会将就招聘、后勤和文化适宜性提供建议。这项基于社区的随机对照试验将包括干预组中的 90 名女性和“常规护理”对照组中的 90 名女性。将在四个时间点采取客观和自我报告措施：基线、干预 16 周后立即进行后测、额外 8 周电话联系维护干预后的延迟后测以及后续后测。为了提高社区对研究的接受度，在所有措施完成后将向对照组提供干预。
