Hunan Cohort Study
The Hunan Cohort Study examines the relationship between exposure to multiple metals and adverse health outcomes, as well as early health impairments, in a general population in China. Over 5,000 participants, aged 7 to 90 years, at various exposure levels, were recruited at baseline between 2016 and 2017 in four regions with heavy metal pollution in Hunan Province, China. Between 2019 and 2022, participants were followed up via in-person assessments and government registries of medical records and deaths. Long-term follow-up surveys are planned to be conducted at three-year intervals, as well as continued linkage to government registries.
