项目摘要

Approximately 55% of the American Population is either overweight or obese. African American women in particular are at significant risk for becoming obese with as many as 49% currently qualifying for obesity (BMI greater than or equal to 30). Low-income, African American women appear less likely to engage in dietary and activity habits associated with weight maintenance and cultural factors may influence their acceptance of excessive body weight. Furthermore, traditional weight loss approaches have been minimally effective with low-income, African American women. Focus group research suggest that African-American women may be responsive to prevention programs which focus on the health b3enefits of weight management and which employ culturally sensitive educational materials. Preliminary research also suggests that a patient centered motivational intervention which uses messages targeted at patient's motivational level, knowledge and perceived barriers may enhance preention efforts. Primary care physicians who provide routine medical care to low-income, African American women are in a unique position to offer preventive services to deter weight gain and promote maintenance of weight loss. This randomized, two arm treatment study will use culturally sensitive educational materials by trained primary care physicians. It will compare physicians directed education (standard care group) to another group who receive customized education plus patient centered messages by primary care physicians. It will attempt to determine a physician delivered patient centered intervention is more effective than standard cre in regard to prevention of weight gain and achievement of weight loss at 6 months. It will also examine whether the groups differ in regard to weight maintenance at 12 and 18 months follow up. It is hypothesized that patients in the patient centered group will demonstrate less weight gain, more weight loss at 6 months, greater maintenance of weight loss at 12 and 18 months as well as dietary and physical activity improvement throughout the observation period than patients receiving standard care.

大约55%的美国人超重或肥胖。特别是非洲裔美国妇女有很大的肥胖风险，目前有多达49%的人符合肥胖标准（BMI大于或等于30）。低收入的非洲裔美国妇女似乎不太可能从事与体重维持和文化因素可能会影响他们接受超重相关的饮食和活动习惯。此外，传统的减肥方法对低收入的非洲裔美国妇女的效果微乎其微。焦点小组研究表明，非洲裔美国妇女可能会对预防计划作出反应，这些计划侧重于体重管理的健康益处，并采用文化敏感的教育材料。初步研究还表明，以患者为中心的动机干预，使用针对患者的动机水平，知识和感知障碍的信息可能会提高预防工作。为低收入非裔美国妇女提供常规医疗保健的初级保健医生在提供预防服务以阻止体重增加和促进维持体重减轻方面处于独特的地位。这项随机化、两组治疗研究将使用由经过培训的初级保健医生提供的文化敏感性教育材料。它将比较医生指导的教育（标准护理组）与另一组谁接受定制的教育加上以患者为中心的信息，由初级保健医生。它将试图确定医生提供的以患者为中心的干预在预防体重增加和实现6个月体重减轻方面比标准cre更有效。它还将检查各组在12个月和18个月随访时体重维持方面是否存在差异。假设与接受标准治疗的患者相比，以患者为中心组的患者在6个月时体重增加较少，体重减轻较多，在12个月和18个月时体重减轻维持较多，以及在整个观察期内饮食和体力活动改善。
