Abstract：Objective To explore the association between dual sensory impairment(DSI)and cognitive function in rural elder-ly,providing a scientific basis for preventing cognitive decline in this population.Methods From January to October 2023,a convenience sampling method was used to survey rural elderly in Zunyi City,Guizhou Province.General information ques-tionnaires,self-assessment sensory function scales,and Mini-Mental State Examination(MMSE)scores were collected.Bi-nary logistic regression analysis was used to assess the relationship between dual sensory function and cognitive function.Results A total of 4 158 questionnaires were distributed,with 3 905 valid questionnaires returned,resulting in a valid re-sponse rate of 93.9％.Among the 3 905 elderly participants,267(6.8％)had DSI,and among those with DSI,162(13.8％)had cognitive impairment.Binary logistic stepwise regression analysis showed female gender,advanced age,living alone,not participating in social activities,and DSI were risk factors for cognitive impairment in rural elderly(P＜0.05).The incidence of cognitive impairment in rural elderly with DSI was 3.516 times higher than that in rural elderly with normal dual sensory function(OR=3.516,95％CI:2.704-4.572,P＜0.05).Conclusion There is an association between dual sensory function and cognitive function in rural elderly.Impaired dual sensory function increases the risk of cognitive impair-ment in rural elderly.Early screening and intervention of dual sensory function in these individuals can help reduce the risk of cognitive impairment.
