Differential Influence of Weight Status on Chronic Diseases by Reported Sexual Orientation Identity in Men.

Purpose: This study examined whether the association between weight status and four chronic diseases (heart disease, hypertension, lifetime asthma, and type 2 diabetes) varied according to sexual orientation identity among adult men, controlling for demographic, socioeconomic, and other factors.

Methods: Pooled data from male adult participants (n = 72,214) in the 2003-2012 California Health Interview Survey were used along with logistic regression models to estimate whether the associations between weight status and chronic diseases varied by sexual orientation identity.

Results: Weight status was positively associated with each of the chronic diseases (hypertension, heart disease, asthma, and diabetes) among both gay and bisexual men and heterosexual men; however, the associations varied significantly by sexual orientation identity. Among gay and bisexual men, the associations were stronger and statistically significant-with the exception of lifetime asthma-particularly for men in the obese classifications, before and after controlling for age, marital status, race/ethnicity, education, income, health insurance status, food security level, smoking, and nativity.

Conclusions: Weight status had stronger detrimental associations with chronic disease among gay and bisexual men despite these men having greater socioeconomic advantage and lower body mass index than heterosexual men. Future research should examine mechanisms, including stress related to minority status, which may lead to greater risks for chronic diseases among sexual minority men.
