Cognitive impairment and its influencing factors in ≥70 years old people in Jianghan Oil Field
Abstract：Objective To study the cognitive impairment (CI) and its influencing factors in ≥70 years old people in Jianghan Oil Field.Methods A total of 10116 ≥70 years old people in Jianghan Oil Field were included in this study.Their serum levels of blood lipids,blood glucose and Hcy were measured,their hepatic and renal function were tested,their blood viscosity was assayed.Their demographic data were recorded and their CI was detected.The diagnosis of dementia and CI and their influencing factors were analyzed.Results The prevalence of dementia was 44.2％ and that of CI was 35.7％ in the 10116 ≥70 years old people.The prevalence of mild CI,Alzheimer's disease,vascular CI and other types of dementia accounted for 21.7％,7.2％,5.9％ and 0.9 ％ respectively.Multivariate logistic regression analysis showed that female gender,hearing and visual acuity loss,poor sleep quality,diabetes,hypothyroidism,cerebrovascular disease,uremia,hyperhomocysteinemia,and whole blood viscosity were the risk factors for CI while physical exercise,drinking tea,doing housework and cheerful personality were the protective factors for CI.Conclusion CI is easy to occur in old people,especially in old females,suffering from chronic diseases,severe hearing and visual acuity loss,poor sleep quality,preventive measures should thus be taken for CI in such people.
