Eating disorders among delivery hospitalizations: prevalence and outcomes.
OBJECTIVE
The purpose of this study was to describe trends in the prevalence of eating disorders among delivery hospitalizations in the United States from 1994 to 2004 and to compare hospital, demographic, and obstetrical outcomes among women with and without eating disorders.


METHODS
Hospital discharge data for 1994 to 2004 from the Nationwide Inpatient Sample (NIS) were used to assess the relationship between eating disorders (anorexia nervosa and bulimia nervosa) and obstetrical complications. Analyses were limited to delivery-related hospitalizations.


RESULTS
There were an estimated 1,668 delivery hospitalizations with an eating disorder diagnosis in the United States in the 11-year period, resulting in an overall rate of 0.39 per 10,000 deliveries. After adjustment for hospital and demographic characteristics, delivery hospitalizations with an eating disorder were significantly more likely than those without an eating disorder to have fetal growth restriction (odds ratio [OR] 9.08, 95% confidence interval [CI] 6.45-12.77), preterm labor (OR 2.78, 95% CI 2.10-3.69), anemia (OR 1.73, 95% CI 1.25-2.38), genitourinary tract infections (OR 1.66, 95% CI 1.03-2.68), and labor induction (OR 1.32, 95% CI 1.01-1.73).


CONCLUSIONS
Although the prevalence of eating disorders among delivery hospitalizations is lower than in the general population, the fact that women with eating disorders are at increased risk of adverse pregnancy outcomes highlights the importance of screening for and appropriate clinical care of eating disorders in pregnancy.
