Abstract: Objective  To investigate the prevalence and risk factors of amnestic mild cognitive impairment(aMCI) among the elderly in Shijiazhuang. Methods   A convenient sampling method was used to investigate 1 614 cases of people over 60 years in 3 community health service centers and 1 nursing home for the elderly in Shijiazhuang. The minimental state examination(MMSE),  montreal cognitive assessment(MoCA),  auditory verbal learning test(AVLT),  digital spantest(DST),  boston naming test(BNT), trail making test(TMT),  Clock Drawing Test,  Animal Fluency Test and ADL were used to assess the examinees' overall cognitive functions, the cognitive domain such as memory,  language,  attention,  visual space, executive function and daily activity ability.The prevalence of aMCI was calculated,  and Logistic regression analysis was used to identify the related risk factors for aMCI. Results  The prevalence of aMCI among the sampled elderly in Shijiazhuang was 16.11%,  and there were significant differences in the prevalence of aMCI among the elderly of different age,  gender,  occupations,  educational levels and marital status  (P<0.01). Age,  gender,  marital status and education level were the factors influencing the aMCI(P<0.05). Conclusion  Old age,  female,  nonspouse and the elderly with low education level are the highrisk groups of aMCI,  so early intervention should be focused on the above groups.
