Taizhou Longitudinal Study (TZL)
TZL explores environmental and genetic risk factors for chronic diseases in a population of adults from Taizhou City in Jiangsu Province, China. Participants aged 30 to 80 and living in the Taizhou districts of Hailin, Gaogang, and Taixing were recruited between 2007 and 2011. Over 120,000 participants participated in the baseline data collection. Follow-up assessments are conducted every three years to monitor participants' health outcomes and lifestyle changes. Several sub-studies have been undertaken on the cohort, focused on neuroimaging and liver disease.
