Many recent clinical and epidemiological studies have demonstrated the effects of vitamin D on health, yet few studies have examined the association of dietary intake of vitamin D during pregnancy with postpartum depressive symptoms. This study examined this association in a large cohort of 74,840 pregnant women who are enrolled in the longitudinal Japan Environment and Children’s Study. Dietary vitamin D intake during pregnancy (specifically after learning of the pregnancy to mid-late pregnancy) was determined using the Food Frequency Questionnaire. Postpartum depressive symptoms 1 mo after delivery were assessed using the Edinburgh Postnatal Depression Scale. Logistic regression analysis showed a reduced risk of postpartum depressive symptoms for all except the first quintile of vitamin D intake: second quintile (adjusted odds ratio [95% confidence interval]: 0.88 [0.82–0.94]), third (0.83 [0.78–0.89]), fourth (0.87 [0.81–0.93]), and fifth (0.90 [0.83–0.97]). Post-adjustment trend tests revealed a significant association between dietary vitamin D intake and postpartum depressive symptoms (p for trend=0.004). Our results revealed a higher vitamin D intake during pregnancy was associated with a lower risk of postpartum depressive symptoms 1 mo after delivery, suggesting the potential applicability of vitamin D in reducing postpartum depression.
