Epilepsy and eating disorders during pregnancy: Prevalence, complications and birth outcome

Abstract

PurposeThe aim was to investigate the prevalence of eating disorders and its relation to pregnancy and delivery complications in childbearing women with epilepsy (WWE). MethodThis study is based on The Norwegian Mother and Child Cohort Study (MoBa) linked to the Medical Birth Registry of Norway. Epilepsy was reported in 706 pregnancies. The remaining cohort (n=106,511) served as the reference group. Eating disorders were diagnosed using DSM-IV criteria adjusted for pregnancy. The risk of preeclampsia, gestational hypertension, diabetes and weight gain during pregnancy as well as delivery outcome (small for gestational age, large for gestational age, ponderal index, low APGAR score, small head circumference) were calculated as odds ratios (ORs) with 95% confidence intervals (CIs) adjusted for maternal age, smoking, parity and socioeconomic factors. ResultsPregnant WWE were significantly more likely to have binge eating disorder (6.5% vs. 4.7%, p<0.05). WWE and comorbid eating disorders had significantly more preeclampsia (7.9% vs. 3.7%, p<0.05), peripartum depression and/or anxiety (40.4% vs. 17.8%, p<0.001) and operative delivery (38.2% vs. 23.5%, p<0.001) than the reference group without epilepsy or eating disorders. After adjustment for confounders, a significantly increased risk of operative delivery (OR 1.96, CI 1.26–3.05) and peripartum depression and/or anxiety (OR 2.17, CI 1.40–3.36) was demonstrated. ConclusionEating disorders in WWE contribute to the increased risk of pregnancy and delivery complications. Health personnel should be aware of eating disorders in WWE and refer them for treatment before pregnancy.
