Abstract

Health benefits of fermented foods are attracting attention worldwide, and they have been traditionally eaten in Japan. Moreover, a recent study showed the association between the higher intake of yogurt and lower prevalence of depressive symptoms during pregnancy. Psychological problems, such as anxiety and depression, during pregnancy are serious health concerns and may increase the risk of adverse outcomes in children. In this study, we explored the association between fermented food consumption and psychological distress in 10,129 pregnant Japanese women, using the fixed data of the Japan Environment and Children’s Study (JECS), an ongoing nation-wide birth cohort study. Food consumption was assessed with a semi-quantitative food frequency questionnaire (FFQ), and the Kessler 6-item psychological distress scale (K6) was administered to eligible women during their second or third trimester to eliminate overlap with the period of hyperemesis gravidarum. The mean median gestation in the subjects was 24.8 weeks. In total, 9,030 subjects completed the K6 questionnaire and FFQ. Importantly, the prevalence of the K6 score of ≥ 13 was 3.1% (280 subjects). This value was lower compared to precedent studies, which may reflect that cooperative and health conscious subject participated in the survey. The multivariate logistic regression analysis indicates that the intake of yogurt, lactic acid beverages, cheese, Japanese pickles, miso soup, or fermented soybeans was not significantly associated with a K6 score of ≥ 13. In conclusion, the present cohort study shows no association between fermented food consumption and psychological distress symptoms during the second or third trimester of pregnancy.
