Abstract

Abstract: Objective: Women with postpartum depressive symptoms (PDS) are at higher risk of postpartum depression (PPD) and require further assessment. Emerging evidence indicates a relationship between the total cholesterol (TC) level of blood and PPD but the results are inconsistent. In this study, we investigated the possible association of change in serum TC levels during pregnancy with the risk of PDS in a Japanese population. Methods: We analyzed complete data on questionnaire responses and serum lipid profiles of pregnant women from 12 datasets obtained from the Japan Environment and Children's Study ( n = 61, 585 to n = 72, 406; 103, 063 pregnancies in total). TC was measured at 3 time points—during early pregnancy, during mid‐late pregnancy, and after delivery—and we calculated changes in TC in 3 ways: by subtracting early pregnancy from mid‐late pregnancy, subtracting mid‐late pregnancy from delivery, and subtracting early pregnancy from delivery. These 6 factors were used as predictors to estimate the risk of PDS at 1 and 6 months after delivery. Results: In multivariable logistic regression analysis, point serum cholesterol level did not predict PDS at any time point except for during mid‐late pregnancy in the second quintile, indicating an increased risk at 6 months. As for change in TC levels, subtracting mid‐late pregnancy from delivery and early pregnancy from delivery showed significant risk reduction for PDS at 1 month. A significant risk reduction was also found for subtracting early pregnancy from mid‐late pregnancy and early pregnancy from delivery at 6 months. Conclusions: Increased cholesterol level during pregnancy is associated with reduced risk of PDS.
