Cross-sectional surveys using cluster sampling.
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.
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.
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.
The prevalence of dementia in the elderly living in groups in Xi'an was high, especially living in NHs.

探讨西安市多家养老院和退伍军人疗养院老年人群痴呆和轻度认知障碍（MCI）的患病率及其多种危险因素。
对来自 4 家养老院和 2 家退伍军人疗养院的 264 名本地老年人进行了多项痴呆筛查测试：简易精神状态检查（MMSE）、日常生活活动（ADL）和 Hasegawa 痴呆量表（HDS）。根据 DSM-III-R 和 Petersen 的标准诊断痴呆和 MCI。还收集了社会人口统计学特征和既往病史。
在养老院和退伍军人疗养院居住的人群中，痴呆的患病率为 36.7%，远高于普通人群，MCI 的患病率为 13.3%，与普通人群相同。痴呆与年龄较大、女性、受教育程度低和居住在养老院有关。男性患 MCI 的患病率明显更高。非常高龄、居住在养老院和严重的 ADL 受损与痴呆和 MCI 的患病率升高相关。
在西安，居住在养老院等群体中的老年人痴呆患病率较高，尤其是居住在养老院的老年人。
