Nut consumption and its associated influence on depressive symptoms have been a growing focus in the current literature. However, this relationship during pregnancy remains poorly understood. This study aimed to explore the relationship between nut consumption and depressive symptoms in the first trimester. Data was drawn from the Chinese Pregnant Women Cohort Study (CPWCS). The frequency of nut consumption was self-reported and women with unclear about nut consumption were excluded. Depression symptom was assessed using the Edinburgh Postnatal Depression Scale (EPDS). EPDS score, ranging from 0 to 30, with ≥10 used as the cut-off to define depression. Chi-square test and logistic regression were conducted to evaluate the relationship between nut consumption and pregnancy depression in the first trimester. Among 8306 participants, the rate of depressive symptoms was 46.6%(n=3872). There was a statistical difference in the rate of depression among pregnant women of different ages, education levels, working status, census register types, annual family income and nut consumption. After controlling confounding factors, the odds ratios (95% confidence interval) of having depression by increasing frequency of nut consumption were 1.00 for <once per week, 0.883(0.772, 1.011) for 1-3 times per week, 0.635(0.552, 0.730) for ≥4 times per week, and this was attenuated. This study suggested that depressive symptoms was related to nut consumption in the first trimester. Further studies are needed to confirm the causality of nut consumption in pregnancy depression.
