What this research studies

You would be invited to give health information and biological samples so researchers can measure organic and inorganic pollutants in your blood and other tissues. They will combine those exposure measurements with genetic and family pedigree data from large multigenerational Mexican American families. The team will use clinical interviews and records to identify people with recurrent major depressive disorder and relate those diagnoses to pollution and genetic patterns. Their methods aim to find how environmental chemicals and inherited genetics together influence who develops repeated episodes of depression.

Who could benefit from this research

Good fit: Adults from multigenerational Mexican American (Chicano/Chicana) families, especially those with a history of recurrent major depressive disorder, would be ideal candidates.

Not a fit: People without a family history of depression or those from non-Hispanic populations may not directly benefit from findings focused on Mexican American pedigrees.

Why it matters

Potential benefit: If successful, this work could help identify environmental and genetic causes of recurrent depression and lead to better prevention, diagnosis, or tailored treatments for affected families.

How similar studies have performed: Prior studies have linked air pollution to depression using indirect exposure measures, but directly measuring personal pollutant levels combined with genomic pedigree analysis is relatively new.
