Analysis of the current status and influencing factors of mild cognitive impairment in elderly people in Ningxia
Objective To explore the epidemic and influencing factors of mild cognitive impairment(MCI)among the elderly people in Ningxia.Methods A stratified cluster random sampling was used to select 5 110 elderly individuals aged over 65 from 3 villa-ges and 8 communities in Ningxia 6 counties(districts)for cognitive impairment screening.The survey included demographic informa-tion,the dementia screening scale(AD8),and the concise community dementia screening scale(CSI-D).The binary logistic regression analysis was used to identify the influencing factors of MCI.Results The prevalence rate of MCI among elderly people in Ningxia region was 12.97%.The results of univariate analysis indicated that gender,age,ethnicity,marital status,monthly family income,residence,alcohol consumption,physical exercise habits,presence of chronic diseases and self-rated health status significantly affected the detec-tion rate of MCI among the elderly people.The results of logistic regression showed that the rural residence(OR=0.355;95%CI:0.258~0.488)and self-rated health(OR=0.301,95%CI:0.206~0.441)were protective factors against MCI onset while being fe-male(OR=1.236,95%CI:1.023~1.496),age over or equal to 75 years old(OR=1.711,95%CI:1.384~2.115),No spouse(OR=1.383;95%CI:1.091~1.754),average family income ≥4 000 yuan(OR=1.63,95%Cl:1.197~2.220)were identified as the risk factors for the incidence of MCI.Conclusion Living in rural areas and self-rated health are protective factors for the incidence of MCl,while female,elderly,unmarried,and average household income>4000 yuan are the risk factors for developing MCI.Therefore,Multifaceted intervention measures are necessary to mitigate cognitive decline among the elderly people.
