Abstract

Objective:

To explore the prevalence of pregnancy-related nausea (PN) and vomiting (PV), and hyperemesis gravidarum (HG), in women with bulimia nervosa (BN) and EDNOS purging subtype (EDNOS-P).

Method:

Pregnant women (38,038) enrolled in the Norwegian Mother and Child Cohort Study had questionnaire-based information on eating disorder diagnosis and PN, PV, and HG. We estimated the odds for PN, PV, and HG using logistic regression.

Results:

Women with BN, purging subtype, but not women with BN, nonpurging subtype, had statistically significant higher odds of PN and PV compared to women without eating disorders. The EDNOS-P group showed significantly higher odds of PV. The odds of HG did not differ significantly between those with and without an eating disorder, or across eating disorder subtypes.

Conclusion:

Our results suggest that eating disorders marked by the symptom of purging are associated with increased odds of PN and PV. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2008
