Monitoring Social Change: Health, Reproduction, Aging
Summary
This continues a 20-year history of collection of in-depth sociodemographic, economic, health services and health behaviors, and clinical exams of 34,000 Chinese individuals from 288 communities, including the previous CHNS2009 collection of 26 biomarkers derived from fasting blood on all respondents aged 7 year and older, 37 toenail biomarkers on all respondents aged 2 and older, and genome-wide association (GWA) data on a subsample of 9,600 respondents in the China Health and Nutrition Survey (CHNS) 2009. We will further enhance the value of this unique survey by adding a follow-up survey to collect and analyze a second wave of fasting blood, and collect and store toenails and extract DNA for future analysis so in total the biomarkers will provide incidence data across cardio metabolic, toxicological and other outcomes, and allow us to complete GWA on the remaining 9,000 individuals with blood samples and in all children aged 0 to 7 years (H1, 253) using buccal swab (saliva) samples.
