Abstract: Objective To understand the impairment of ability in activities of daily living （ADL） and influencing factors in residents aged ≥60 years in urban and rural areas of Yunnan Province, so as to provide a basis for the development of prevention and control measures. Methods A multi-stage sampling method was used to investigate residents aged ≥60 years, living in certain urban and rural areas in Yunnan Province for more than 1 year and with local household registration. The contents included the basic situation, behavior and ability in ADL of the participants. Univariate and multivariate logistic regressions were used to analyze factors influencing the impairment of ability in ADL. Results A total of 3 978 residents aged ≥60 years were surveyed in this study, with an average age of （68. 5 ± 6. 6） years. The total score of activity in ADL was （15. 3 ± 4. 0） and the impairment rate of ability in ADL was 25. 6%. Multivariate logistic regression analysis showed that the residents aged 71-80 years （OR = 2. 48）, 81-93 years （OR = 7. 10）, with more chronic diseases （OR = 1. 27, 1. 90, 2. 35） were more likely to have higher risk of daily life impairment of ability in ADL, while those who were male （OR = 0. 77）, had higher education level （OR = 0. 46, 0. 34, 0. 21）, maintained marriage status （OR = 0. 69）, occasionally or frequently communicated with neighbors （OR = 0. 66, 0. 51）, occasionally or frequently participated in the community activities （OR = 0. 78, 0. 54）, exercised regularly （OR = 0. 68）, occasionally or frequently read books （OR = 0. 51, 0. 31）, occasionally or frequently played cards or Mahjong （OR = 0. 47, 0. 64）, and lived in urban area （OR = 0. 51） were more likely to have lower risk of impairment of ability in activities of ADL. Conclusion The elderly residents in urban and rural areas in Yunnan Province suffered from serious impairments of ability in activities of ADL, which were influenced by many factors. The fairness and accessibility of medical resource allocation in urban and rural areas should be improved. Propaganda and education of related health knowledge and healthy lifestyle should be strengthened and advocated.
