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

 描述（由申请人提供）：目前的研究表明，82.1%的非洲裔美国妇女超重或肥胖。肥胖是一个严重的健康问题，有许多共病。最近的证据鼓励研究人员将精力集中在AA人群的体重增加预防上。消费健康，能量平衡的饮食和从事体育活动对预防体重增加和心血管疾病很重要。然而，研究人员已经确定了心理社会障碍的存在，使AA女性无法参与这些行为。一个特别的障碍是暴饮暴食症（BED），这与严重的肥胖有关。通过减少AA女性的暴饮暴食事件，可以预防体重增加，降低CVD风险。 拟议的试点可行性研究的目的是测试的可行性和初步效果的8周，以社区为基础，食欲意识训练干预（AAT）超重AA妇女在床上的风险。AAT是一种认知行为干预方法，它成功地帮助人们减少暴饮暴食和暴饮暴食，同时也有助于维持体重。AAT还提供有关饮食的指导和指导，以应对情绪和理解饥饿和饱腹感的生物信号。 拟议研究的具体目的是：目的1：使用实验设计，评估AAT在自我报告暴饮暴食的超重AA女性的社区样本中的可行性和可接受性;目的2：记录饮食变化（暴食，饥饿，饱腹感，饮食自我效能和健康饮食障碍），CVD风险（体重，血压和腰围）和心理社会功能（生活质量，抑郁症状）在干预组与等待名单对照组。我们假设，在8周的试验结束时，AAT干预组的参与者报告的暴食、抑郁症状和健康饮食障碍比等待名单对照组的参与者少。 申请人为第三人 一年的联合MPH/博士生，其职业目标是在一所研究密集型大学开发一项干预研究计划，促进AA人群的体重维持和心血管健康拟议的研究将提供重要信息，以增加申请人对超重/肥胖的理解。肥胖的AA妇女在一项干预措施，旨在解决心理障碍，采取健康的生活方式，支持体重维持。拟议的试点可行性研究将使用约40名自我报告至少一次暴饮暴食事件的妇女的社区样本，并将使用经验证的问卷进行数据收集。此外，焦点小组将提供有关干预措施可接受性的宝贵定性数据。研究结果将提供重要数据，以确定建议为AA女性提供的暴食干预措施的可行性，并进一步发展和完善AAT干预措施。这些发现可能会提出创新的干预方法，以提高其覆盖范围，并扩大对AA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.
