The DLCC study aims to contribute to knowledge on the determinants of noncommunicable chronic diseases in China. Initially, the study included close to 115,000 participants from the Beijing, Tianjin, and Hebei (BHT) areas. In 2021, an additional 9,866 participants from Guangdong and Hebei provinces joined the study. Participants were recruited through several sub-cohorts, each targeting specific life stages and health factors: the Early-Life BTH cohort, BTH Medical Examination cohort, Cohort on Chronic Disease in Community Natural Population, Occupational Cohort, and the Chaoshan-Hakka-Baoding General Population Cohort. Follow-up assessments have been conducted, with one completed by the end of 2021, presenting the changes in health over time.
