Abstract
ObjectiveTo analyze the prevalence and related factors of dementia and mild cognitive impairment(MCI)in elderly people in nursing homes in Zhejiang Province.
MethodsA cross-sectional survey was conducted in 4 community nursing homes in 12 prefecture-level cities in Zhejiang Province from May to November 2014 through multi-stage stratified random cluster sampling, with 908 elderly patients finally included.Standardized age and gender adjusted prevalence rates were calculated by using the direct method of population standardization(the 6th Population Census of Zhejiang Province, 2018). Univariate and multivariate Logistic regression models were used to screen for related factors for dementia and MCI.
ResultsThe crude prevalence rates of dementia, Alzheimer's disease(AD), vascular dementia(VaD)and MCI were 42.4%(385/908), 22.0%(200/908), 1.9%(17/908)and 21.6%(196/908), respectively.After adjusting for age and gender, the prevalence rates of dementia, AD, VaD and MCI were 40.6%, 20.8%, 1.6% and 19.4%, respectively, which were significantly higher than those of the general community.Logistic regression analysis showed that old age, low educational level and family income were associated with dementia and MCI, including dementia-related factors such as illiteracy, middle level family income and history of stroke and MCI-related factors such as age(80-84, 85-89 years old), educational level.
ConclusionsElderly people in nursing homes have high rates of dementia and MCI and deserve heightened attention.Meanwhile, comprehensive prevention and treatment of dementia and MCI in elderly patients can be carried out by changing lifestyle and other related risk factors.
