title: Mild cognitive impairment risk factor survey of the Xinjiang Uyghur and Han elderly.
abstract: To understand risk factors of the Xinjiang Uyghur, Han two ethnic elderly with mild cognitive impairment (mild cognitive impairment, MCI), and provide evidence for in-depth study of the causes and prevention of MCI. The MCI epidemiological survey was based on Xinjiang Uyghur and Han residents with 60 years of age or older. The total number of participants is 5398, including 3931 Uyghur residents, and 1467 Han residents. There are 456 participants with MMSE score 2 points above the demarcation points, excluded from the survey for dementia, cerebrovascular disease and other central nervous system disorders, according to case-control study method of random selection in epidemiological survey. In accordance with the clinical diagnostic criteria of MCI, which is from Disorder Diagnostic and Statistical Manual (the revised version of the fourth edition (DSM-IV) from of the American Psychiatric Association, there are 305 cases of MCI, including 159 cases of Han, 146 cases of Uyghur. In the Han groups: univariate analysis showed a correlation (P < 0.05) between sex, age, blood pressure, triglyceride (TG), low density lipoprotein (LDL-ch) and MCI. Multivariate Logistic regression analysis showed: age, hypertension, TG, LDL-ch (increased) may increase the risk of MCI (OR values were: 1.115, 1.981, 1.315, 1.495, with P < 0.05). In the Uyghur groups: univariate analysis showed a correlation (P < 0.05) between age, gender, hypertension, abnormal glucose metabolism, TG, TC, LDL-ch and MCI. Multivariate Logistic regression analysis showed: age, hypertension, abnormal glucose metabolism, TG, TC, LDL-ch (increased), women have a higher risk of MCI (OR values were: 1.063, 2.145, 2.879, 2.078, 1.429, 1.485, 0.462, P < 0.05). Age, hypertension, TG and LDL-ch are risk factors of MCI for Han population, while age, hypertension, abnormal glucose metabolism, TG, TC and LDL-ch are risk factors of MCI for Uyghur population.
