Objective To study the status quo of frailty and disability and to explore their correlation in the community-dwelling elderly. Methods A total of 664 elderly people aged 80 years and above living in a community in Beijing from November 2018 to November 2019 were selected. A structured questionnaire, Fried frailty phenotype and Katz ADL were used to investigate and evaluate the respondents. SPSS 22.0 was used for data analysis. Depending on the data type, t-test or Chi square test was used for comparison between groups. Spearman correlation analysis was performed to test the correlation between frailty and disability. Results Among 664 elderly people in the community, there were 636 cases of valid result of frailty assessment, and 655 cases of valid result of disability assessment. The incidences of frailty and disability among the elderly were 17.1% (109/636) and 42.4% (278/655). The incidence of frailty was higher in groups of more advanced age, coronary heart disease and type 2 diabetes mellitus (P<0.05). The incidence of disability was higher in females, patients with low education and coronary heart disease (P<0.05). Spearman correlation analysis showed a positive correlation between frailty and disability (r＝0.400, P<0.01) and a general correlation between its internal components (P＜0.05 or P＜0.01). Conclusion The incidences of frailty and disability among the community-dwelling elderly are high. Age, gender, education level and chronic diseases affect their incidences. There is a significant correlation between frailty and disability and wide correlation among the internal components.
