芬兰研究发现孕产妇心理健康与肠道菌群有关

Core Findings - A new study from Turku University indicates significant differences in gut microbiota composition between women experiencing depression and anxiety during pregnancy or postpartum and those without such symptoms [1][2] - Depression and anxiety are common psychological issues during pregnancy and postpartum, affecting 10% to 20% of women [1] Group 1: Research Methodology - The study tracked 419 women from early pregnancy to one year postpartum, assessing their mental health through questionnaires and analyzing gut microbiota samples collected during early and late pregnancy [1] Group 2: Key Findings - Women with more severe depressive symptoms during pregnancy and postpartum had higher levels of various streptococci in their gut [2] - Increased levels of Faecalibacterium in late pregnancy were associated with postpartum depression, while higher levels of Clostridium were linked to both prenatal depression and postpartum anxiety [1][2] Group 3: Implications - The research supports the hypothesis that chronic low-grade inflammation in pregnant women may be a significant factor in triggering depression and anxiety symptoms [2] - The study suggests that gut microbiota composition could influence bodily inflammatory responses, thereby affecting maternal mental health [2] - Future interventions could consider dietary and nutritional approaches to modify gut microbiota composition, potentially reducing the risk of psychological disorders during pregnancy [2]
