To follow up long-term dietary status, physical condition, behavioral lifestyle and health status of Chinese residents, this study was carried out based on Chinese Nutrition and Health Surveillance 2010-2012(CNHS 2010-2012). According to east-west-central regional stratification, Jiangsu, Fujian(eastern region), Shanxi(central region), Chongqing and Guangxi Zhuang Autonomous Region(western region) were included into the study, with 2 follow-up sites of each province. Dietary intake, physical status, psychological behaviors, physical activities, lifestyle, nutrition-related diseases, muscle and cognitive function of the elderly aged 65 and above were collected through questionnaire, physical measurements, dietary surveys and laboratory tests. The project was implemented through a scientific research design, standardized survey procedures and full-process quality control, relying on Centers for Disease Control and Prevention System. A total of 10 659 participants were enrolled. The decade-long dynamic data on nutrition and health provide basic data and scientific references for formulating nutrition and health-related policies for Chinese residents.
