Abstract

Muscle Dysmorphia (MD) and its psychological impacts on women, especially within sexual minorities, are still relatively understudied. The objective of this study was to compare the relationship of MD symptoms and psychological distress between heterosexual women and lesbian/bisexual women. Our sample consisted of 479 Brazilian cisgender women from the community, aged between 18 and 70 years (M = 32.78; SD = 10.45). Among them, 327 (68.27 %) identified as heterosexual, 134 (27.98 %) as bisexual, and 18 (3.76 %) as lesbian. To ensure there was no bias due to measurement error, the psychometric properties of the instruments in the sample were tested, and invariance between the groups was assessed. t-tests, structural equation modeling, and latent profile analyses were conducted to comprehend the differences between the groups. The results indicated significant differences and a greater severity of MD symptoms and distress for lesbian/bisexual women. The implications of these results are discussed, emphasizing the need for further exploration of MD studies within sexual minorities.

肌肉畸形症状对异性恋女性和同性恋/双性恋女性的困扰的影响差异

肌肉畸形症（MD）及其对女性，尤其是性少数群体女性的心理影响研究相对较少。本研究旨在比较异性恋女性和女同性恋/双性恋女性的肌肉畸形症状与心理困扰之间的关系。我们的样本包括 479 名来自社区的巴西双性恋女性，年龄在 18 岁至 70 岁之间（男 = 32.78；女 = 10.45）。其中，327 人（68.27%）被认定为异性恋，134 人（27.98%）被认定为双性恋，18 人（3.76%）被认定为女同性恋。为确保测量误差不会造成偏差，对样本中的工具进行了心理测量特性测试，并评估了各组之间的不变量。结果表明，女同性恋/双性恋女性在 MD 症状和困扰方面存在明显差异，且严重程度更高。本文讨论了这些结果的影响，强调了在性少数群体中进一步探索 MD 研究的必要性。

期刊介绍： Eating Behaviors is an international peer-reviewed scientific journal publishing human research on the etiology, prevention, and treatment of obesity, binge eating, and eating disorders in adults and children. Studies related to the promotion of healthy eating patterns to treat or prevent medical conditions (e.g., hypertension, diabetes mellitus, cancer) are also acceptable. Two types of manuscripts are encouraged: (1) Descriptive studies establishing functional relationships between eating behaviors and social, cognitive, environmental, attitudinal, emotional or biochemical factors; (2) Clinical outcome research evaluating the efficacy of prevention or treatment protocols.
