Differences in weight stigma between gay, bisexual, and heterosexual men.

Gay and bisexual men may experience more weight stigma than heterosexual men; however, research is limited. We examined differences in experienced weight discrimination, weight bias, and internalized weight bias in two studies: the first comprising gay (n = 351), bisexual (n = 357), and heterosexual (n = 408) men, and the second comprising gay (n = 614) and bisexual (n = 123) men. In Study 1, bisexual men reported experiencing more weight discrimination than gay (r = .07) and heterosexual (r = .08) men. Bisexual (Glass' Δ = 0.41) and gay (Δ = 0.37) men reported greater internalized weight bias than heterosexual men. Heterosexual men reported more weight bias than gay (Cohen's d = 0.35) and bisexual (d = 0.46) men. In Study 2, gay men reported more internalized weight bias than bisexual men (d = 0.26). Sexual orientation did not moderate the relationships of weight stigma with either body dissatisfaction or psychological quality of life. Among gay and bisexual men, experiencing weight discrimination predicted diminished psychological quality of life through internalized weight bias and body dissatisfaction. Our research emphasizes the importance of assessing weight stigma among sexual minorities and suggests bisexual men might be particularly vulnerable to weight stigma.
