Understanding causes of depression, anxiety, and related chronic fatigue

An Integrative Approach to the Etiology of Internalizing Disorders in the Lifelines Cohort

NIH-funded research Virginia Commonwealth University · NIH-11234290

Researchers are using medical records, family information, genetics, and gut microbiome data from thousands of adults to find what leads to depression, anxiety, chronic fatigue, fibromyalgia, and IBS.

What this research studies

This project analyzes information from Lifelines, a long-term group of about 167,000 adults in the North-Eastern Netherlands, many of whom are family members followed over time. It combines medical histories, mood and symptom questionnaires, genetic data, blood measures, and gut microbiome samples to look for shared and unique causes of depression, anxiety disorders, chronic fatigue syndrome, fibromyalgia, and irritable bowel syndrome. The team builds multi-level statistical models that include family relationships, environment, and molecular data to trace how these conditions begin and overlap. Because Lifelines follows people every five years, researchers can also study how symptoms and diagnoses change over time.

Who could benefit from this research

Good fit: Adults (age 21 and older) with a history of depression, anxiety disorders, chronic fatigue syndrome, fibromyalgia, or irritable bowel syndrome, and their family members, would be most relevant.

Not a fit: People under 21, those not enrolled in the Lifelines cohort, or anyone seeking immediate clinical treatment will not receive direct care from this research.

Why it matters

Potential benefit: If successful, this work could help doctors identify different biological pathways behind these conditions and point to more precise ways to diagnose, prevent, or treat them.

How similar studies have performed: Large cohort studies have previously linked genetics, environment, and the microbiome to mood and functional disorders, but combining family, microbiome, and multi-level models in the Lifelines cohort is relatively new.
