China Longitudinal Healthy Longevity Study

To shed new light on a better understanding of the determinants of healthy longevity of human beings. Until present, the CLHLS conducted face-to-face interviews with 10-20,000 individuals aged 65 years or older in 1998, 2000, 20002, 2005, 2008-09, 2010-11, and 2013-14 respectively, using internationally compatible questionnaires. The objectives of CLHLS includes: 1. Collect intensive individual interview data including health, disability, demographic, family, socioeconomic, and behavioral risk factors for mortality and healthy longevity. 2. Follow up the oldest-old and the comparison group of the younger elders, as well as some of the elders' adult children to ascertain changes in their health status, care needs and costs, and associated factors. We will also ascertain mortality and causes of death, as well as care needs, costs, and health/disability status before death. 3. Analyze the collected data to estimate the impacts of social, behavioral, environmental, and biological risk factors that are determinants of healthy longevity and mortality in the oldest-old. 4. Compare the findings with results from other studies of large populations at advanced age. Our specific objective is to understand how psychological, physiological, environmental and lifestyle indicators explain the survival among Chinese older adults.

We are drafting several manuscripts investigating the associations between lifestyle indicators and survival among Chinese older adults as well as gene-environmental interactions in determining cardiovascular health.

Six major policy reports based on census and CLHLS data submitted to the Chinese central government were reviewed by and received written comments from the President, Prime Minister and 3 Vice Prime Ministers, respectively, in 2003, 2005, 2008, 2012, 2013 and 2015. Other >20 policy reports based on CLHLS was submitted to various governmental agencies.
