Abstract

BACKGROUND AND PURPOSE
The objective of this study was to determine the prevalence of and risk factors for dementia in residents aged 65 years and older in a Chinese nursing home.
METHODS
A cross-sectional study was carried out in a nursing home located in Hangzhou, Zhejiang Province, China. Cognitive status, including the presence of dementia and mild cognitive impairment (MCI), was measured using a combination of medical history and objective cognitive assessments. Logistic regression analysis was conducted to predict the associated risk factors.
RESULTS
In total, 943 residents (334 males and 609 females) aged 84.00±6.67 years (mean±SD) were included. Dementia was diagnosed in 420 (44.5%) residents, and MCI was diagnosed in 195 (20.7%). Mild, moderate, and severe dementia were present in 20.3%, 14.0%, and 65.7% of those in the dementia group, respectively. Logistic regression analysis revealed that dementia was associated with a low education level (p=0.000), an advanced age (p=0.010), and a history of stroke (p=0.023).
CONCLUSIONS
Our study found a high prevalence of dementia in a Chinese nursing home, and a high prevalence of patients with severe dementia. Risk factors for dementia included a low educational level, an advanced age, and a history of stroke. Appropriate interventions need to be applied to this population.
