How gut bacteria and stress affect mental health in young people

Host DNA methylation as a mechanism of microbiome influence on internalizing behavior

NIH-funded research Arizona State University-Tempe Campus · NIH-10849679

This study is looking at how stress in early life can change the bacteria in our gut and how that might affect feelings like anxiety and depression in kids and teens, helping us find ways to improve mental health through better gut health.

What this research studies

This research investigates the relationship between early life stress, gut microbiome composition, and mental health outcomes such as anxiety and depression in children and adolescents. It aims to understand how stress during critical developmental periods can alter gut bacteria, which may in turn affect brain function and behavior through changes in DNA methylation. By examining these connections, the study seeks to uncover potential biological mechanisms that link gut health and mental health, providing insights into how interventions might be designed. Participants may undergo assessments of their gut microbiome and mental health to contribute to this understanding.

Who could benefit from this research

Good fit: Ideal candidates for this research are children and adolescents aged 0-21 who are experiencing anxiety or depression.

Not a fit: Patients who do not have anxiety or depression or are outside the age range of 0-21 may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new strategies for preventing and treating anxiety and depression in young people by targeting gut health.

How similar studies have performed: Other research has shown promising results in understanding the gut-brain connection, suggesting that this approach could yield valuable insights.
