Objective To investigate the status of health condition and activities of daily living of “50630” retired cadres in Mianzhu, and analyze the related factors affecting their activities of daily living. Methods According to the registration information of Mianzhu administration of elderly cadres in Sichuan, the method of cluster sampling was adopted in March 2019 to select retired cadres who participated in work between October 1st, 1949 and June 30th, 1950 in urban and rural areas respectively. The survey and analysis were carried out using the self-designed general condition questionnaire, Berg balance scale, Hoffer walking ability rating scale, and modified Barthel Index, to understand the activities of daily living ability of retired cadres and analyze the relevant factors affecting their self-care ability of daily life. Results A total of 64 “50630” retired cadres were investigated, with an average age of (86.39±3.37) years. 64.06% of the patients with poor balance function needed wheelchair, 10.94% could not walk, and 56.25% were heavily dependent on activities of daily living. Age (r=−0.421, P=0.001) and underlying diseases (r=−0.060, P=0.032) were negatively correlated with activities of daily living. Balance ability (r=0.658, P<0.001), walking ability (r=0.393, P=0.001), spouse status (r=0.669, P<0.001), care status (r=0.830, P<0.001), place of residence (r=0.706, P<0.001) were positively correlated with activities of daily living. Education level (r=0.096, P=0.380) and gender (r=0.122, P=0.265) had no correlation with activities of daily living. Multiple linear regression analysis showed that the main influencing factors of daily living activities of “50630” retired cadres in Mianzhu were balance function, walking ability, spouse or not and type of care. Conclusions There are many related factors affecting the activities of daily living of “50630” retired cadres, which can be intervened according to basic diseases, balance function and walking ability. Through multi-disciplinary and multi-sectoral cooperation, integrating community health service resources, providing all-round health care services, formulating personalized rehabilitation measures, and organizing community group activities, it is possible to improve their social participation, psychological status, and ability of daily living activities, and reduce the disability, so as to further improve the quality of life of veteran cadres.
