A Preliminary Investigation of Body Dissatisfaction and Eating Disorder Symptomatology with Bisexual Individuals

摘要

Body dissatisfaction and eating disorder symptomatology were examined in bisexual individuals (n = 139 women, n = 37 men) and compared to lesbian/gay (n = 51 women, n = 96 men) and heterosexual individuals (n = 82 women, n = 34 men) in a U.S. online sample. Age, body mass index (BMI), income, and exercise frequency served as covariates. MANCOVA results showed a significant gender by sexual orientation interaction and significant main effects of gender and sexuality. Univariate tests were used to explore multivariate results. ANCOVA results for body dissatisfaction showed a significant gender by sexual orientation interaction. Post-hoc comparisons revealed higher levels of body dissatisfaction among all groups compared to heterosexual men. ANCOVA results for eating disorder symptomatology showed a significant main effect of sexual orientation. Post-hoc comparisons revealed higher levels of eating disorder symptoms among bisexual compared to heterosexual individuals. For bisexual men, gay community involvement, maladaptive social comparison, drive for muscularity, self-esteem, gender role orientation, and body dissatisfaction were explored as predictors of eating disorder symptomatology while controlling for age, BMI, exercise frequency, and income in a hierarchical regression analysis. The same factors, minus body dissatisfaction, were explored as predictors of body dissatisfaction in bisexual men. For bisexual women, similar factors, with the exception of drive for muscularity, were explored. Drive for muscularity predicted body dissatisfaction and exercise frequency predicted eating disorder symptomatology in bisexual men. BMI and self-esteem predicted body dissatisfaction in bisexual women; gay community involvement and body dissatisfaction predicted eating disorder symptomatology.
