Influence of sexual orientation and age on disordered eating attitudes and behaviors in women

OBJECTIVE: We evaluated the influence of age on the association between sexual orientation and disordered eating attitudes and behaviors in women. METHOD: Heterosexual (n=47) and homosexual (n=45) women recruited from the community completed self-report questionnaires including the Body Esteem Scale, the Eating Disorders Inventory-2, the Reasons for Exercise Inventory, and the Self Esteem Scale. RESULTS: A multivariate analysis of variance of eating disorder variables revealed a main effect for sexual orientation on drive for thinness and exercise to control weight and a main effect for age on body mass index (BMI) and body dissatisfaction, but it did not reveal a significant interaction between sexual orientation and age. DISCUSSION: Sexual orientation may influence certain types of disordered eating attitudes and behaviors in women such as endorsing an extreme ideal of thinness. However, homosexual and heterosexual women reported more similarities than differences.
