Abstract: Objective To explore the current status of depression and its influencing factors among the elderly with cognitive frailty in the community. Methods A convenience sampling method was used to select elderly individuals with cognitive frailty from six communities in Beijing as the subjects of the study from July to December 2023. Montreal Cognitive Assessment (MoCA) combined with Fried frailty phenotype was used to assess cognitive frailty, and the geriatric depression scale (GDS-15) was used to assess depressive status. Basic information of the subjects including gender, age, marital status, education level, economic status, living situation, comorbidity, sleep quality, social support, nutritional status, activities of daily living and loneliness was recorded. Logistic regression analysis was used to analyze the influencing factors of depression in the community elderly with cognitive frailty. Results A total of 539 questionnaires were distributed and 529 valid questionnaires were collected, with an effective response rate of 98.15%. Among the 529 elderly individuals with cognitive frailty, 128(24.2%) presented with depression,and the average GDS-15 score was 3.4±2.0. Multiple logistic regression analysis showed that ability of daily living, sleep quality, and loneliness were independent influencing factors of depression in the community elderly with cognitive frailty. Conclusions The depressive status of the community elderly with cognitive frailty is not optimistic. Ability of daily living,sleep quality and loneliness are independent influencing factors for depression in the population.
