Abstract
BACKGROUND: Postpartum depression, which has affected one in six women after giving birth, can exert detrimental effects on maternal, children and family well-being. This study investigated the association between dietary patterns and postpartum depression among Chinese women. METHODS: A total of 1659 participants were recruited and collected between July 2015 and June 2017 in Tianjin, China. The Chinese version of the Self-Rating Depression Scale was used to assess depressive symptoms at 6-12 weeks postpartum. Information about diet was obtained using an 81-item food frequency questionnaire. Logistic regression models were used to assess relationships between dietary patterns and the risk of postpartum depression. RESULTS: Six dietary patterns were identified by principal component analysis, including beverage, vegetable, cereal-meat, nut-fruit, egg and seafood patterns. The highest tertile (T3) of the nut-fruit pattern was significantly associated with a decreased risk of postpartum depression (OR: 0.740, 95% CI: 0.573-0.955, p = =0.020). Moreover, T3 of the seafood pattern was associated with a lower risk of postpartum depression than the lowest tertile (T1) of this pattern (OR: 0.753, 95% CI: 0.580-0.978, p = =0.033). No other associations were found. LIMITATIONS: A retrospective study. CONCLUSIONS: The nut-fruit pattern and seafood pattern were associated with a decreased risk of postpartum depression in Chinese women. The present findings reinforce the importance of an adequate diet of fruit, nuts, and seafood for postpartum women.
