Status and associated factors of mild cognitive impairment among the elderly in Shanghai community

Objective To explore the status of mild cognitive impairment （MCI） among the elderly in Shanghai communities， and to identify the factors associated with MCI.

Methods The Montreal Cognitive Assessment-Basic （MoCA-B） was used to screen for MCI in elderly adults. Logistic regression analysis was conducted to identify the factors associated with MCI.

Results Among 629 participants， 226 （35.90%） were positive for MCI. Older age （OR=1.04， 95%CI： 1.01-1.07）， lower family income （average OR=2.20， 95%CI： 1.01-4.80； poor OR=2.59， 95%CI： 1.03-6.50）， hearing impairment affecting daily life （OR=1.86， 95%CI： 1.19-2.91）， and anxiety symptoms （OR=1.58， 95%CI： 1.02-2.44） were associated with the positive for MCI. Living in central urban area （OR=0.57， 95%CI： 0.37-0.89） and having higher social support （OR=0.97， 95%CI： 0.94-1.00） were protective factors for MCI.

Conclusion The current status of MCI among the elderly in Shanghai communities is not optimistic. It is important and necessary to establish the cognitive-friendly community for the elderly.
