A Feasibility Study to Reduce Binge Eating in Overweight African American Women

 描述(申请人提供)：目前的研究表明，82.1%的非裔美国女性超重或肥胖。肥胖是一个严重的健康问题，有许多并存的疾病。最近的证据鼓励研究人员将他们的努力集中在预防AA人群的体重增加上。食用健康、能量平衡的饮食和从事体力活动对预防体重增加和心血管疾病非常重要。然而，研究人员已经确定了心理社会障碍的存在，这些障碍削弱了再生障碍性贫血女性从事这些行为的能力。一个特殊的障碍是暴饮暴食障碍(Bed)，它与严重肥胖有关。通过减少AA女性暴饮暴食的次数，可以防止体重增加，降低心血管疾病的风险。拟议的试点可行性研究的目的是测试为期8周的以社区为基础的食欲意识训练干预(AAT)对有床上风险的超重AA妇女的可行性和初步效果。AAT是一种认知行为干预，在帮助个人减少暴饮暴食和暴饮暴食方面取得了成功，同时也有助于保持体重。AAT还提供关于进食的指导和指导，以回应情绪和理解饥饿和饱腹感的生物信号。这项拟议研究的具体目的是：目标1：采用实验设计，评估AAT在社区超重AA妇女自我报告暴食的可行性和可接受性；目标2：记录干预组与等待名单对照组在饮食(暴食、饥饿、饱腹感、饮食自我效能和健康饮食障碍)、心血管疾病风险(体重、血压和腰围)和心理社会功能(生活质量、抑郁症状)方面的变化。我们假设，在为期8周的试验结束时，AAT干预组的参与者报告的暴饮暴食、抑郁症状和健康饮食障碍将比等待名单控制组的参与者少。申请者是第三名 一年公共卫生硕士/博士研究生，其职业目标是在一所研究密集型大学开发一个干预研究计划，在AA人群中促进体重维持和心血管健康。拟议的研究将提供重要的信息，以增加申请者对超重/肥胖的AA女性参与干预的理解，该干预旨在解决采用支持体重维持的健康生活方式的心理社会障碍。拟议的试点可行性研究将使用以社区为基础的约40名妇女样本，她们自我报告至少一次暴饮暴食事件，并将使用有效的问卷进行数据收集。此外，焦点小组将提供有关干预可接受性的有价值的定性数据。研究结果将为拟议的针对再生障碍性贫血妇女的暴食干预的可行性提供重要数据，并进一步发展和完善AAT干预。这些发现可能会为干预提供的创新方法提供建议，这将扩大其覆盖范围，并扩大对再障人群心脏健康的关注。

 DESCRIPTION (provided by applicant): Current research indicates that 82.1% of African-American women are overweight or obese. Obesity is a serious health problem with numerous co-morbidities. Recent evidence has encouraged researchers to focus their efforts on weight gain prevention in the AA population. Consuming a healthy, energy-balanced diet and engaging in physical activity are important for prevention of weight gain and CVD. However, researchers have identified the presence of psychosocial barriers that detract AA women from engaging in these behaviors. One particular barrier is binge eating disorder (BED), which is associated with severe obesity. By reducing binge eating episodes in AA women, weight gain may be prevented and CVD risk reduced. The purpose of the proposed pilot feasibility study is to test the feasibility and preliminary effect of an 8-week, community-based, Appetite Awareness Training intervention (AAT) for overweight AA women at risk for BED. AAT, a cognitive-behavioral intervention, has been successful in aiding individuals to reduce binge eating and overeating, while also aiding in weight maintenance. AAT also provides instruction and guidance on eating in response to emotion and understanding biological signals of hunger and satiety. The specific aims of the proposed study are: Aim 1: Using an experimental design, assess the feasibility and acceptability of AAT in a community-based sample of overweight AA women who self-report binge eating; Aim 2: Document changes in eating (binges, hunger, satiety, eating self-efficacy, and barriers to healthy eating), CVD risk (body weight, blood pressure, and waist circumference) and psychosocial functioning (quality of life, depressive symptoms) in the intervention group vs. the wait-list control group. We hypothesize that participants in the AAT intervention will report fewer binges, depressive symptoms, and barriers to healthy eating than those in the wait-list control group at the completion of the 8-week trial. The applicant is a 3rd year joint MPH/PhD student whose career goal is to develop a program of intervention research at a research-intensive university that promotes weight maintenance and cardiovascular health in the AA population The proposed study will provide important information to increase the applicant's understanding of engaging overweight/obese AA women in an intervention designed to address psychosocial barriers to the adoption of a healthy lifestyle that supports weight maintenance. The proposed pilot feasibility study will use a community-based sample of approximately 40 women who self-report at least one binge eating episode and will use validated questionnaires for data collection. In addition, focus groups will provide valuable qualitative data on intervention acceptability. The study findings will provide important data on the feasibility of the proposed binge eating intervention for AA women and further the development and refinement of the AAT intervention. These findings will potentially suggest innovative approaches to the intervention delivery that will enhance its reach and also expand the focus on heart health in the AA population.
