Factors associated with binge eating disorder in pregnancy.

OBJECTIVE

To identify factors associated with incidence and course of broadly defined binge eating disorder (BED) in pregnancy.

METHOD: As a part of the Norwegian Mother and Child Cohort Study (MoBa), 45,644 women completed a questionnaire at approximately 18 weeks of gestation.

RESULTS

Incidence of BED was significantly associated with lifetime sexual abuse, lifetime physical abuse, lifetime major depression, symptoms of anxiety and depression, low life satisfaction, low self-esteem, low partner relationship satisfaction, smoking, alcohol use, lack of social support, and several weight-related factors. Continuation was negatively associated with thoughts of being overweight before pregnancy. Remission was positively associated with thoughts of being overweight before pregnancy and negatively associated with overvaluation of weight.

DISCUSSION: Onset of BED in pregnancy was associated with psychological, social and weight-related factors, as well as health behaviors and adverse life events. In women with prepregnancy BED, thoughts of being overweight before pregnancy and overvaluation of weight were associated with course of BED during pregnancy.
