How Oral Microbiome Impacts Maternal Mental Health and Pregnancy
New research links oral microbiome changes to mental health symptoms in pregnant women, suggesting potential interventions for improved maternal well-being.
The Link Between Oral Microbiome and Mental Health During Pregnancy
Recent research from Michigan State University (MSU) has found out a fascinating connection between the oral microbiome and mental health during pregnancy. The study, published in BMJ Mental Health, explores how life stress and symptoms of anxiety, depression, and post-traumatic stress disorder (PTSD) affect the number and types of microbes in the saliva of pregnant women.
This is the first study to investigate the relationship between oral microbiome composition and maternal mental health, focusing on the mouth and throat’s microbial environment, known as the oral microbiome.
Study Overview: Assessing Mental Health and Saliva Samples
The study involved 224 pregnant women enrolled in the Michigan Prenatal Stress Study, who were assessed for recent stress and mental health symptoms during their second trimester. As part of the study, participants provided saliva samples, which were analyzed for microbial content.
The researchers found significant variations in the oral microbiome based on whether the women reported symptoms during their assessments, such as of
- Anxiety
- Depression
- life stress
- PTSDÂ
Study Findings: Oral Microbiome and Mental Health Symptoms
Interestingly, women with high symptoms of anxiety or depression exhibited oral microbiomes with greater “alpha diversity.”
- This means their saliva contained a wide variety of microbial species, with each type present in relatively even amounts.
On the other hand, women showing symptoms of PTSD had high “beta diversity” in their oral microbiomes, meaning the microbial species in their saliva were distinctly different from those of women with low PTSD symptoms.
Furthermore, the research identified specific microbes that were more abundant in women with high stress and mental health symptoms, suggesting that the oral microbiome might reflect a person’s psychological state.
Potential Implications for Maternal Health
Joseph Lonstein, a professor in MSU’s Department of Psychology and the lead researcher, emphasized the importance of positive mental health for mothers’ overall well-being and their ability to care for their infants. He hopes this study will encourage further research into how microbes—beyond those in the gut, which are already well-studied—could influence mental health in mothers and even in people who are not mothers.
The researchers suggest that the oral microbiome might be a potential target for interventions aimed at improving mental health during pregnancy. Future studies could be done to enhance maternal mental health and address high levels of life stress as we explore the role ofÂ
- Probiotic treatments
- Dietary changes
- Â Oral health recommendations
Looking Ahead: Interventions to Improve Maternal Well-being
The findings open up new possibilities for addressing poor psychological well-being during pregnancy. While probiotic treatments for gut health are already being explored, the team believes similar strategies could be applied to the oral microbiome. By targeting oral cavity microbes through interventions, such as dietary adjustments and probiotics, future research could help mothers dealing with stress and mental health challenges improve their overall health during pregnancy.
