Abstract

Background: Four decades of research has assessed how gender and/or sexual orientation contribute to levels of body dissatisfaction (BD). The findings have proven somewhat equivocal and little attention has been paid to potential moderators. Method: The current meta-analysis compared BD in gay and heterosexual men (38 overall effects), and lesbian and heterosexual women (25 overall effects). Additional pairwise comparisons explored differences between heterosexual men and heterosexual women, gay men and lesbians, gay men and heterosexual women, and heterosexual men and lesbian women.

Results: Random effects model meta-analyses revealed greater levels of BD in gay men compared to heterosexual men (g = -0.36, 95% CI -0.43, -0.29). By contrast, BD was greater in heterosexual women than lesbians (g = 0.09 95% CI 0.03, 0.15). Year of publication and mean difference in age between gay and heterosexual samples moderated the relationship between BD and sexual orientation, but only for men. Pairwise comparisons indicated that BD is highest in heterosexual women and lowest in heterosexual men.

Conclusions: Findings indicate that both gender and sexual orientation influence BD. We identified a number of limitations in the existing research base, and make recommendations for future research.
