Objective: To investigate the Activity of Daily life (ADL) among individuals aged 100 and above, in Hainan. Methods: From June 2014 to December 2016, a community-based cross-sectional study was conducted among individuals aged 100 and over in Hainan province. Data regarding basic information, ADL, prevalence of major age-related diseases was collected in this population. Loss of ADL among these centenarians was described and its determinants examined. Results: The prevalence of ADL loss in centenarian population was 72.5%, with the top four items of ADL loss as stair-climbing (79.0%), moving (59.1%), walking (44.3%) and using toilet (41.3%). Results showed that tea consumption, good both on vision and audition were possible protective factors for the functions of ADL. Low level of education and vitamin D deficiency seemed as risk factors for the slowing-down of ADL (P<0.05). Conclusions: The prevalence of ADL loss among centenarians appeared relatively high. Years of education, tea consumption, degrees of vision, audition and vitamin D deficiency were possible risk factors responsible for the ADL loss in this centenarian population.
