To investigate the Activity of Daily life (ADL) among individuals aged 100 and above, in Hainan. 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. 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 (<0.05). 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.
