Objective To investigate the status of cognitive frailty and its influencing factors among the elderly with type 2 diabetes in community, so as to provide reference for the management of cognitive frailty. Methods A total of 291 elderly patients with type 2 diabetes in community were investigated using Geriatric Depression Scale-15, Frailty Phenotype and Mini-Mental State Examination. Results Totally 25（8.6%） of the participants developed cognitive frailty. Multivariate logistic regression analysis showed that, individual monthly income, sleep duration at night, glycated hemoglobin and depression symptoms were the influencing factors of cognitive frailty (P＜0.05 for all). Conclusion The prevalence of cognitive frailty among the elderly with type 2 diabetes in the community is relatively high. The diabetic elderly with lower personal income, insufficient sleep duration at night, high glycated hemoglobin or depression symptoms are more likely to suffer from cognitive frailty. The community health centers should pay attention to the screening and intervention for their cognitive frailty.
