Abstract

Abstract

Objective To explore the incidence rate of mild cognitive impairment(MCI) among the elderly which transferred to Alzheimer disease(AD) and to analyze the related influencing factors. Methods 10 urban communities were selected through stratified cluster sampling as the research sites where 361 patients with MCI were screened from 1 942 residents aged over 60 years old. Questionnaires and laboratory assays were used to collect data from subjects, including characteristics of demographic, life style, medical history, Alzheimer-associated neuronal thread protein, (AD7 C-(NTP)), amyloid β-protein 42(Aβ42) and amyloid β-protein 40(Aβ40), etc. Patients with MCI were followed up for three years to determine whether they progressed to AD. Results 121 of 361 patients of MCI converted to AD, and the incidence rate of MCI to AD was 9.49% person-years. According to the results of Logistic regression analysis model, elder(80-89 years)(OR=3.651, 95% CI:1.295-10.297, P < 0.001), female(OR=2.603, 95% CI:1.136-5.966, P < 0.001), heavy drinking(OR=1.479, 95% CI:1.343-1.627, P < 0.001), increased ADL score(OR=1.790, 95% CI:1.443-2.220, P=0.031) and smoking(OR=1.157, 95% CI:1.091-1.224, P < 0.001) were the risky factors of the transition of MCI to AD. The increase of Moca score(OR=0.766, 95% CI:0.681-0.861, P < 0.001) was the protective factor of the transition. Conclusions We should strengthen our monitor on elder female MCI patients, and promote healthy lifestyles among the elders, encouraging them to actively participate in physical exercises and reading, in order to delay patients' transition of MCI to AD.
