Interpersonal predictors of dieting practices among married couples.

The relations between couples' marital quality and dieting behavior were examined. One-hundred eighty-seven married couples' dieting behaviors, marital quality, body mass index, weight concerns, depression, and self-esteem were assessed. Results indicate that the relation between healthy dieting behaviors and marital quality is similar for both husbands and wives. However, among wives, marital discord predicted unhealthy dieting behaviors, even after wives' body mass index, weight concerns, self-esteem, and depression were controlled for. Furthermore, wives' self-esteem interacted with marital quality when predicting unhealthy dieting. These findings suggest gender differences in the relations between marital quality and dieting behaviors and are consistent with previous research suggesting that men and women have differential response patterns to marital disharmony, with women tending to internalize negative affect experienced in their marriage.
