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）的发病率和死亡率在少数民族和经济上处于不利地位的妇女中较高，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研究行为改变，关注影响行为改变的个人态度和技能、社会文化因素和环境因素。该研究的主要目的是测试16周文化上适当的行为/社会支持生活方式干预（一次咨询会议和16周小组会议）对体重、体重指数和腰围的影响，与常规护理、最小接触对照组（一次咨询会议）相比，超重或低收入肥胖妇女。干预的目标是让女性（25到50岁）以每周1到2磅的速度减少10%的体重。次要目的是：a)测试16周干预对身体健康、身体活动水平、总能量摄入、来自总脂肪、饱和脂肪和反式脂肪的卡路里摄入百分比、水果和蔬菜摄入量、饮食和身体活动的自我效能感、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周电话联系维持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局的长期维持情况。干预前活动将包括焦点小组，以确保干预的文化敏感性。社区顾问委员会将在招聘、后勤和文化适宜性方面提供建议。这项以社区为基础的随机对照试验将包括90名妇女作为干预组，90名妇女作为“常规护理”对照组。将在四个时间点采取客观和自我报告措施：基线、干预16周后的即时后测、电话联系维持干预额外8周后的延迟后测和随访后测。为了提高社区对研究的接受度，在所有措施完成后，将对对照组进行干预。
