Sexual minority women (SMW) have a higher prevalence of obesity and weight-related health disparities when compared with heterosexual women that may be explained by differences in food intake. This systematic review had two primary aims: (1) synthesize the results for food intake outcomes among SMW, organized primarily according to the dietary risk assessment; and (2) identify possible theoretically informed moderators and mediators of the association between women's sexual identity and differences in food intake. The literature search was conducted using the PubMed and PsycInfo databases to identify articles published until March 23, 2021. Inclusion criteria were: (1) included a sample of adult SMW, (2) quantitatively assessed a food intake outcome, and (3) published in an English language peer-reviewed journal in the past 10 years. Thirteen articles were eligible and included in the review. Overall, there were inconsistent findings comparing food intake between SMW and heterosexual women. There was some evidence to suggest that identity characteristics beyond sexual orientation (e.g., race and gender presentation) and place of residence (e.g., urban vs. rural settings) were plausible moderators. Only one variable pertaining to SMW's developmental history, mother's diet quality, was identified as a possible mediator. The main critiques of the literature include the predominance of convenience sampling, cross-sectional data, and inconsistencies in the measurement of sexual orientation and diet. This review highlights that further work is needed to consider additional hypotheses to explain disparities in obesity and weight-related health disparities among SMW to inform comprehensive behavioral intervention strategies.
性少数群体女性（SMW）的肥胖率和与体重相关的健康差异高于异性恋女性，这可能是由于饮食摄入的差异所致。本系统评价有两个主要目的：（1）根据饮食风险评估，主要对性少数群体女性的饮食摄入结果进行综合；（2）确定女性性身份与饮食摄入差异之间关联的可能理论上有影响的调节因素和中介因素。文献检索使用了 PubMed 和 PsycInfo 数据库，以确定截至 2021 年 3 月 23 日发表的文章。纳入标准为：（1）包括成年性少数群体女性的样本；（2）定量评估饮食摄入结果；（3）在过去 10 年内以英文同行评审期刊发表。有 13 篇文章符合条件并纳入了综述。总体而言，比较性少数群体女性和异性恋女性的饮食摄入情况的结果不一致。有一些证据表明，除了性取向（如种族和性别表达）和居住地（如城市与农村环境）以外的身份特征可能是合理的调节因素。只有一个与性少数群体女性的发展历史、母亲的饮食质量有关的变量被确定为可能的中介因素。文献的主要批评包括便利抽样、横断面数据以及性取向和饮食测量的不一致性占主导地位。本综述强调，需要进一步开展工作，以考虑其他假设来解释性少数群体女性肥胖和与体重相关的健康差异，为综合行为干预策略提供信息。
