Examining binge eating in daily life: Working toward reducing obesity disparities in racially diverse lesbian and heterosexual women

摘要 年轻的成年女同性恋者超重和肥胖的可能性是异性恋者的两倍， 黑人女性同样比白色女性更容易肥胖。因此，这些少数民族妇女 易患与肥胖相关的合并症，包括心脏病、中风和2型糖尿病， 暴饮暴食的行为（暴饮暴食，饮食失控）导致肥胖 并且在年轻成年女性中特别普遍。尽管在暴饮暴食方面存在着有据可查的差异， 众所周知，同性恋妇女，特别是少数民族的促成因素。在研究年轻人 性取向未知、未被评估或未被报告的妇女（以下简称一般性妇女） 研究表明，暴饮暴食与情感状态、社会进程和健康有关。 行为。本研究组和其他研究人员使用基于移动的技术的生态瞬时评估 (EMA)研究了日常情感和社会经验如何影响年轻女性的日常饮食 生活这些研究主要是对白色女性的一般样本进行的;情感状态、社会关系、 日常生活中的过程和健康行为对女同性恋者暴饮暴食的影响尚不清楚。一致 根据少数民族压力理论，初步数据也表明，性少数民族的压力-或压力的人， 被污名化的群体由于其边缘化的社会地位而面临的风险-可能的影响是 女同性恋者，但独特的少数民族的经验，在暴饮暴食的作用还没有使用EMA检查。 种族、饮食相关因素和性少数群体特有的因素也可能会影响日常联系， 还没有得到充分的探索。特别是，性别和种族少数群体交叉的影响， 身份（即，作为一个黑人女同性恋者）在暴饮暴食还没有被考虑。解决这些 在暴食和性少数文献的限制下，拟议的研究考察了情感，社会， 健康行为，以及在自然环境中与暴饮暴食相关的性少数特定因素。年轻 成年女同性恋者（n=150，50名黑人）和异性恋者（n=150，50名黑人），年龄在18-30岁之间， 饮食行为将完成简短的基于智能手机的EMA调查，每天五次， 两周的行为。研究目的包括检查日常情感，社会和健康行为因素 影响女同性恋者的饮食，以及性少数群体特有的经历如何独特地促成狂欢 日常生活中的饮食。我们还将探讨种族如何缓和这些协会。EMA设计允许 检查自然环境中的日常过程，包括种族多样的女同性恋和异性恋 妇女使人们能够确定造成不平等的因素。这项研究填补了研究空白， 了解日常生活中导致暴饮暴食的一般和性少数群体特有的因素，以及 种族在这些关联中的作用。这些信息对于为文化发展提供信息至关重要， 为女同性恋者量身定制的干预措施，最终目标是减少暴饮暴食和肥胖的差异。

Abstract Young adult lesbian women are twice as likely to be overweight and obese as their heterosexual peers and Black women are similarly more likely to be obese than White women. These minority women are thus more prone to obesity-related comorbidities including heart disease, stroke, and type 2 diabetes, which are leading causes of death in the U.S. Binge eating behaviors (overeating, loss of control of eating) contribute to obesity and are particularly prevalent in young adult women. Despite well documented disparities in binge eating, little is known about contributing factors in lesbian women, and in particular racial minorities. In studies of young women where sexual orientation is not known, assessed, or reported (hereafter referred to as general samples), research demonstrates binge eating is associated with affective states, social processes, and health behaviors. Studies by our group and others using mobile technology-based ecological momentary assessment (EMA) have examined how daily affective and social experiences influence young women's eating in everyday life. These studies were conducted with general samples of primarily White women; how affective states, social processes, and health behaviors in daily life impact lesbian women's binge eating remains unclear. Consistent with minority stress theories, preliminary data also suggest sexual minority stress – or the stress people from stigmatized groups are exposed to due to their marginalized social status – likely influences binge eating in lesbian women, but the role of unique minority experiences in binge eating has not been examined using EMA. Race, eating-related factors, and sexual minority-specific factors may also moderate daily associations, but have not been fully explored. In particular, implications of having intersecting sexual- and racial-minority identities (i.e., being a Black lesbian women) on binge eating have yet to be considered. To address these limitations in the binge eating and sexual minority literatures, the proposed study examines affective, social, health behavior, and sexual minority-specific factors associated with binge eating in natural settings. Young adult lesbian (n=150, 50 Black) and heterosexual (n=150, 50 Black) women ages 18-30 who engage in binge eating behavior will complete brief smartphone-based EMA surveys five times daily and in response to binge behaviors for two weeks. Study aims include examining how daily affective, social, and health behavior factors impact lesbian women's eating, and how sexual minority-specific experiences uniquely contribute to binge eating in daily life. We will also explore how race moderates these associations. The EMA design allows examination of daily processes in natural settings, and including racially diverse lesbian and heterosexual women allows identification of factors that contribute to disparities. This study fills research gaps by expanding understanding of general and sexual minority-specific factors that contribute to binge eating in daily life, and the role of race in these associations. Such information is critical for informing the development of culturally tailored interventions for lesbian women, with the ultimate goal of reducing binge eating and obesity disparities.
