Obesity is reaching epidemic proportion in the United States with recent surveys showing that over half of all U.S. adults are overweight or obese. Obesity is difficult and treat and relatively few individuals are successful at long-term maintenance of weight loss. These facts make prevention of obesity an important goal. The present application targets the prevention of pregnancy-associated obesity in African-American women. Pregnancy is a high-risk time for the development of obesity. The average weight retention after pregnancy is 2-5 pounds but many women retain considerably more weight postpartum. Previous studies have shown that African-American women retain more weight following pregnancy than Caucasians and are less likely to diet to loss the excess pregnancy weight. African-American women have a higher rate of obesity than Caucasians, and the role of pregnancy in the obesity of this population is unknown. The present application describes a randomized, controlled, parallel-arm intervention study in postpartum African-American women. The overall goal of the present proposal is to evaluate the effectiveness of traditional versus Internet-aided behavior modification for weight management in postpartum African-American women. The Internet-based intervention will be used in addition to face-to-face group sessions to allow for more extensive behavioral feedback and contact with interventionists. Thus, this proposal makes use of innovative technology in the prevention of obesity in a population at extremely high risk for excess weight gain. The research will address the primary hypothesis that the use of the Internet-aided behavior intervention will be more effective than traditional behavioral intervention program in preventing excess postpartum weight retention. Fifty-six previously non-obese postpartum women who retained > 25 pounds of excess weight after pregnancy will be studied in this pilot program. All subjects will receive 12 bimonthly group sessions providing core information on healthy diet, activity, and weight loss. Half the subjects will be assigned to an experimental arm involving an Internet-aided behavioral modification to supplement group sessions. The Internet intervention will continue for 3 months past the core group intervention for a total of 9 months of intervention. The control group will receive only the group sessions. This application addresses a critical gap in our knowledge of effective obesity preention strategies in African-American women, a group at high risk for obesity. In addition, these studies allow us to address ways of preventing the development of obesity following pregnancy, which has relevance to all women.

肥胖症在美国已达到流行病的比例，最近的调查显示，超过一半的美国成年人超重或肥胖。肥胖是困难和治疗和相对较少的个人是成功的长期维持体重减轻。这些事实使预防肥胖成为一个重要目标。本申请的目标是预防非裔美国妇女的妊娠相关肥胖。怀孕是肥胖症发展的高风险时期。怀孕后的平均体重保持在2-5磅，但许多妇女在产后保留了更多的体重。以前的研究表明，非洲裔美国妇女在怀孕后比白人保留更多的体重，并且不太可能通过节食来减掉多余的怀孕体重。非洲裔美国妇女的肥胖率高于白人，怀孕在这一人群肥胖中的作用尚不清楚。本申请描述了在产后非裔美国妇女中的随机、对照、平行臂干预研究。本提案的总体目标是评估传统与互联网辅助行为矫正对产后非洲裔美国妇女体重管理的有效性。除了面对面的小组会议之外，还将使用基于互联网的干预措施，以获得更广泛的行为反馈和与干预人员的联系。因此，该提案利用创新技术预防体重过度增加风险极高的人群的肥胖症。该研究将解决主要假设，即使用互联网辅助的行为干预将比传统的行为干预计划更有效地防止产后体重过多。五十六例以前不肥胖的产后妇女，她们在怀孕后保留了超过25磅的多余体重，将在这个试点项目中进行研究。所有受试者将接受12个双月一次的小组会议，提供有关健康饮食、活动和减肥的核心信息。一半的受试者将被分配到一个实验组，该实验组涉及互联网辅助的行为改变，以补充小组会议。互联网干预将在核心组干预后持续3个月，总共干预9个月。控制组将只接收组会话。这个应用程序解决了一个关键的差距，我们的知识，有效的肥胖预防策略，在非洲裔美国妇女，一组肥胖的高风险。此外，这些研究使我们能够解决预防怀孕后肥胖发展的方法，这与所有女性都有关系。
