Additional Details

DACOS is a national large- scale, longitudinal, multi-center, prospective, cohort study of natural person aged 35 to 75. The baseline survey and the follow-up surveys will be conducted in 5 areas covering the eastern, northern, western, southern and middle parts of China. In this study 100,000 natural person will be regularly followed up for 5 years(visited once a year), with the loss rate ≤15%. Three parts will be carried in the form of interview, physical examination and biological sample collection. During the interview, the investigators plan to do some questionnaires to learn participants' demographic characteristics, life style, disease history, healthy condition(EQ-5D-5L, SDS,), cognition state(AD-8, MMSE, MoCA) and the results of TCM syndrome differentiation(Score of Dampness syndrome and TCM constitution scale). All biological specimens (including blood, feces, urine, saliva and tongue coating) will be collected and stored in the biological resource center until researchers request their use. With the building up of this cohort, the researchers will analyze the causality between dampness syndrome and specific chronic diseases such as diabetes, coronary heart disease, cancer, dementia and so on.
