Abstract:
Objective:To investigate the prevalence and influencing factors of amnestic mild cognitive impairment of rural elderly in Guizhou province, which aims to provide scientific basis for the prevention and control of cognitive impairment in the elderly.Methods:Adopting a multi-stage cluster sampling method, a total of 1 535 rural Han and Bouyei elderly people aged 60 and above were selected from Guiyang city and Qiannan prefecture in Guizhou province as the survey subjects for the current situation survey, including demographic sociological characteristics, such as social was utilized behavior, social behavior disease history, height and weight and so on.Mini-mental state examination was utilized to measure cognitive function and SPSS 26.0 statistical software was used to perform χ 2 inspection and multivariate unconditional Logistics regression analysis to calculate odds ratio ( OR) and 95% confidence interval (95% CI). Results:A total of 242 elderly patients with aMCI were detected (15.8%). The results of univariate analysis showed that ethnicity(χ 2=4.333, P<0.05), gender(χ 2=18.367, P<0.01), marital status(χ 2=9.721, P<0.01), occupation(χ 2=7.786, P<0.01), annual family income(χ 2=28.085, P<0.01), current smoking(χ 2=11.873, P<0.01), specific hobbies(χ 2=25.968, P<0.01), physical exercise(χ 2=11.871, P<0.01), living style(χ 2=13.190, P<0.01), and activity participation(χ 2=13.004, P<0.01) all had an impact on aMCI. Multivariate Logistic regression analysis showed that Bouyei nationality( P<0.05, β=0.288, OR=1.333, 95% CI=1.002-1.775) and the women( P<0.05, β=0.516, OR=1.676, 95% CI=1.233-2.278)were risk factors for aMCI, and high annual family income( P<0.05, β=-0.839, OR=0.432, 95% CI=0.308-0.606), specific hobbies( P<0.05, β=-0.580, OR=0.560, 95% CI= 0.394-0.795), physical exercise( P<0.05, β=-0.410, OR=0.664, 95% CI=0.493-0.894), participation in activities( P<0.05, β=-0.424, OR=0.654, 95% CI=0.488-0.877), and non-living alone( P<0.05, β=-0.563, OR=0.569, 95% CI= 0.374-0.866) were the protective factors.Comparison of the prevalence of the disease between the Han and Bouyei nationalities, the detection rate of aMCI for the Bouyei elderly (18.0%) was higher than that of the Han (14.1%) (χ 2=4.333, P<0.05). After stratification according to gender, family annual income, specific hobbies, physical exercise, participation in activities and living style, the detection rate of elderly female subjects of Bouyei nationality was higher than that of Han nationality, whose difference was statistically significant (χ 2=5.562, P<0.05). The detection rate of Bouyei elderly was higher than that of Han when the annual household income was less than 30 000, and the difference was statistically significant (χ 2=8.570, P<0.01). Conclusion:The incidence of aMCI among the elderly of Bouyei nationality is higher, and the incidence of aMCI among females is higher than that of males, which should be paid more attention to.It is of vital importance to strengthen health education and publicity, guide the formation of knowledge-belief-behavior health-related behavior patterns, so as to improve the quality of life and reduce the risk of cognitive impairment.
