Nausea and vomiting of pregnancy in women with bulimia nervosa and eating disorders not otherwise specified.
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).


METHODS
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.


CONCLUSIONS
Our results suggest that eating disorders marked by the symptom of purging are associated with increased odds of PN and PV.
