Abstract Objective To study the cognitive impairment and its influencing factors in people aged 60 years old or above. Methods From April to June in 2015，A total of 1 576 people aged 60 years or above in Yiwu were selected by the cluster random sampling method. The cognitive function of the respondents was evaluated by Zhejiang Major Public Health Monitoring?Program Questionnaire and Mini-Mental State Examination （MMSE）. Multivariate logistic regression model was used to analyze the influencing factors for cognitive impairment in the elderly. Results A total of 1 569 people were effectively investigated，of which 121（7.71%）were diagnosed with cognitive impairment. The results of multivariate logistic regression analysis showed that advanced age （OR70~=1.792，95%CI：1.135-2.830；OR80~=4.060，95%CI：2.487-6.628），female （OR=1.739，95%CI：1.135-2.664），poor domestic economic condition（OR=2.339，95%CI：1.239-4.415） were the risk factors for cognitive impairment，while living with more than 4 people（OR=0.462，95%CI：0.246-0.867）and physical exercise（OR=0.592， 95%CI：0.356-0.983）were the protective factors for cognitive impairment. Conclusion The prevalence of cognitive impairment was 7.71% in the elderly in Yiwu. Age，gender，family economic condition，housing condition and physical exercise were associated with cognitive impairment.
