Pregnancy intention in relation to maternal and neonatal outcomes in women with vs without psychiatric diagnoses 87 Results General characteristics In total, 1219 women with and 1093 women without current/past psychiatric diagnoses were included. Figure 4.1 presents the inclusion process. Table 4.1 displays demographic features for both study groups. Women with current/past psychiatric diagnoses were on average 0.6 years younger (p=0.015), more often unemployed (p<0.001) and smoked more often during pregnancy (p<0.001) than women without current/past psychiatric diagnoses. Alcohol use, parity and the presence of somatic illnesses were comparable between the two groups. Ethnicity differed between groups (overall p-value<0.001) as Caucasian were more strongly represented in the current/past psychiatric diagnosis group (48.3% vs. 37.2% in the reference group) and Turkish were more strongly represented in the reference group (12.2% vs. 6.3% in the current/past psychiatric diagnosis group). Association between current/past psychiatric diagnoses and unintended pregnancies The incidence of UPs differed between women with (39.0%) versus without current/past psychiatric diagnosis (29.6%) in unadjusted (OR 1.56, 95% CI 1.24--1.97, p<0.001) and adjusted models (OR 1.56, 95% CI 1.23– 2.00, p<0.001), see Table 4.2. Subgroup analyses showed significantly higher UP rates in women with depressive disorders (43.2% UPs, adjusted OR 1.67, 95% CI 1.24--2.26, p=0.001), substance related and addictive disorders (66.7% UPs, adjusted OR 4.29, 95% CI 1.90–10.03, p=0.001) and personality disorders (49.1% UPs, adjusted OR 2.64, 95% CI 1.38–5.11, p=0.004) compared to women without these disorders.
