NCT ID NCT00341237

First seen Jun 25, 2026 · Last updated Jun 25, 2026

Summary

This study looks at how your genes and the environment you live in combine to influence common diseases like diabetes, heart disease, and asthma. Researchers are collecting health questionnaires, exposure surveys, and genetic data from 25,000 adults. The goal is to better understand why some people get sick while others don't, and to guide future prevention efforts.
