Abstract
Design
Cross-sectional surveys using cluster sampling.
Objectives
To explore the prevalence of dementia and mild cognitive impairment (MCI) in several
nursing homes (NHs) and veteran care homes (VCHs) in Xi'an City and their various
risk factors.
Participants and measurements
264 native elderly people from four NHs and two VCHs were examined with several screening
tests for dementia: Mini Mental State Examination (MMSE), Activities of Daily Living
(ADL) and Hasegawa Dementia Scale (HDS). Diagnosis of dementia and MCI were made according
to DSM-III-R and Petersen's criteria. Socio-demographic characteristics and past history
were also collected.
Results
Dementia prevalence was 36.7% in those living in NHs and VCHs, much higher than that
of normal population and the prevalence of MCI was 13.3% which was the same as in
normal population. Dementia was associated with old age, female, low education level
and living in NHs. Men had significantly higher prevalence odds for MCI. Very old
age, living in NHs and severe ADL impairment were correlated with higher prevalence
odds for dementia and MCI.
Conclusion
The prevalence of dementia in the elderly living in groups in Xi'an was high, especially
living in NHs.
