The effects of sexual orientation on body image and attitudes about eating and weight.

SUMMARY We assessed the effect of sexual orientation on body image and attitudes toward eating and weight using data collected from lesbians and heterosexual women in three US cities. Data were analyzed using ordinary least squares regression controlling for a number of demographic characteristics. Findings indicate that while lesbian sexual orientation is predictive of positive body image and fewer negative attitudes toward eating and weight, the effects are modest. Body mass index (BMI), frequency of exercise, race, and self-image were the strongest predictors of body image; BMI, race, and city of residence were the strongest predictors of attitudes toward eating and weight. The authors conclude that while belonging to a lesbian subculture may provide some protection against the societal imperative toward thinness, it likely does not counter the larger societal preference that women be thin.
