Stressful life events during pregnancy (table 2)
Having at least one stressful life event during pregnancy was associated with both early and late PPD (aOR=2.0, 95%CI 1.5-2.6, p<.001; and aOR=2.3, 95%CI 1.8-3.1, p<.001 respectively). The number of stressful life events during pregnancy was also associated with an increased risk of both early PPD (aOR=1.4, 95%CI = 1.3-1.6 per additional life event) and late PPD (aOR=1.2, 95%CI = 1.2-1.3 per additional life event, p<.001 for both).
Regarding stressful obstetrical events, early PPD was associated with concomitant chronic physical disease, emergency consultation during pregnancy and perineal trauma (aOR=1.6, 95%CI 1.1-1.2, p=.006, aOR=1.3, 95%CI 1.0-1.7, p=.03 and aOR=1.5, 95%CI 1.0-2.3, p=.03 respectively), while late PPD was associated only with emergency consultation during pregnancy (aOR=1.5, 95%CI 1.2-2.0, p=.002). Other stressful obstetrical events were not associated with either early or late PPD.
