Sexual Minority Stress, Adverse Childhood Experiences, and Obesity Among Gay Men in Taiwan: Findings from a Panel Study.

Purpose: Obesity is linked to personal behaviors and external stressors. Despite emerging evidence that sexual minority stress (SMS) and adverse childhood experiences (ACEs) are associated with the risk of obesity, little is known about their independent and interactive effects on sexual minority men. This study investigated these relationships using panel data. Methods: Self-identified gay and bisexual adult men in Taiwan were recruited through Facebook advertisements to complete an online questionnaire. This study reports only on data from the gay subsample ( n  = 731, mean age = 28.05 years, standard deviation = 5.75 years) as the bisexual subsample ( n  = 132) was insufficient for comparative statistical analysis. Over two time points, respondents reported their body weight and height, experiences with SMS, and ACEs on an online survey platform. Data analysis was conducted using multiple logistic regression to determine the individual and interactive effects of the ACE score, ACE components, and SMS on the odds for obesity. Results: Almost 16% of the respondents met the criterion for obesity (body-mass index ≥27). In the adjusted models, neither SMS nor ACEs had significant associations with the likelihood of obesity. Only the interaction term of SMS and childhood sexual abuse was significant, indicating that victims of sexual abuse have an increased likelihood of obesity that SMS may intensify. Conclusions: This study shows that gay men who experience childhood sexual abuse and SMS accumulatively faced an increased risk of obesity. Healthy weight promotion for these men should address these stressors.
