之前的研究已经确定了性少数群体和异性恋女性之间的健康差距，包括性少数群体女性肥胖率和暴饮暴食的比率增加。暴饮暴食行为的既定预测因素包括负面情绪和社会文化过程；然而，这些研究通常是在性身份未知或未报告的年轻女性样本中进行的。很少有研究评估性少数群体特有的因素(例如，少数民族压力和与女同性恋者、男同性恋者、双性恋者、变性人和同性恋社区的联系)如何影响性少数群体女性的暴饮暴食。此外，还没有研究在不同种族的样本中检查这些过程，也没有研究考虑交叉的少数族裔身份(例如，黑人和性少数)可能会如何影响饮食行为。现实生活中的健康和经历(她的生活)项目旨在通过生态瞬时评估来澄清年轻的异性恋和性少数群体女性暴饮暴食的现实预测因素。将针对所有女性考察情感、社会和健康行为因素在暴饮暴食中的作用(目标1)，也将考虑针对性别少数群体女性参与者的特定性别预测因素(目标2)。还将审查种族、与身体和饮食相关的因素以及特定性别少数群体因素的个人水平调节因素，以更好地了解现实世界中暴饮暴食的预测因素在不同人口群体中可能存在的差异(目标3)。研究人员的目标是从美国各地招募150名性少数族裔和150名异性恋女性，其中每组至少有50名黑人女性，使用基于网络的招聘方法。资格标准包括身份识别为女性，年龄在18岁至30岁之间，以及在过去两周内至少有两次暴饮暴食。参与者必须认可仅或主要被男性吸引(被认为是异性恋)，或仅被或主要被女性吸引，或有目前或最近的女性伴侣(被认为是性少数)。符合条件的参与者完成最初的基于网络的基线调查，然后完成14天的生态瞬时评估，包括完成早上和睡前的调查和每天5次的提示调查，以及在暴饮暴食后由用户发起的调查。这些数据将使用一系列多水平模型进行分析。数据收集工作于2021年2月开始。我们目前招收了129名性少数族裔妇女和146名异性恋妇女。数据收集预计将于2022年秋季完成。现实生活中的健康和体验项目旨在阐明性少数群体和异性恋女性在预测暴饮暴食的人内因素方面的潜在差异，并为性少数群体女性的饮食障碍干预提供信息。讨论了在招募性少数群体妇女方面的挑战，包括确定资格标准和远程数据收集的考虑。DERR1-10.2196/41199
Previous research has identified health disparities between sexual minority and heterosexual women, including increased rates of obesity and binge eating in sexual minority women. Established predictors of binge eating behavior include negative emotions and sociocultural processes; however, these studies are generally conducted in samples of young women where sexual identity is not known or reported. There is a dearth of research evaluating how sexual minority–specific factors (eg, minority stress and connectedness to the lesbian, gay, bisexual, transgender, and queer community) may affect binge eating in sexual minority women. In addition, no studies have examined these processes in racially diverse samples or considered how intersecting minority identities (eg, Black and sexual minority) may affect eating behaviors. The Health and Experiences in Real Life (HER Life) Project aims to clarify real-world predictors of binge eating in young heterosexual and sexual minority women using ecological momentary assessment. The role of affective, social, and health behavior factors in binge eating will be examined for all women (aim 1), and sexual minority–specific predictors will also be considered for sexual minority women participants (aim 2). Person-level moderators of race, body- and eating-related factors, and sexual minority–specific factors will also be examined to better understand how real-world binge eating predictors may differ for various demographic groups (aim 3). Researchers aim to recruit 150 sexual minority and 150 heterosexual women from across the United States, including at least 50 Black women for each group, using web-based recruitment methods. The eligibility criteria include identifying as a woman, being aged between 18 and 30 years, and having had at least two binge eating episodes in the last 2 weeks. Participants must endorse being only or mostly attracted to men (considered heterosexual) or only or mostly attracted to women or having a current or most recent female partner (considered sexual minority). Eligible participants complete an initial web-based baseline survey and then 14 days of ecological momentary assessment involving the completion of a morning and before-bed survey and 5 prompted surveys per day as well as a user-initiated survey after binge eating episodes. The data will be analyzed using a series of multilevel models. Data collection started in February 2021. We have currently enrolled 129 sexual minority women and 146 heterosexual women. Data collection is expected to conclude in fall 2022. The Health and Experiences in Real Life Project aims to elucidate potential differences between sexual minority and heterosexual women in within-person factors predicting binge eating and inform eating disorder interventions for sexual minority women. The challenges in recruiting sexual minority women, including the determination of eligibility criteria and considerations for remote data collection, are discussed. DERR1-10.2196/41199
