长谷川和夫痴呆量表在农村老年人群中的测查

An epidemiological survey of elderly people in a rural area using Hasegawas Dementia Scale

以长谷川和夫痴呆量表（ＨＤＳ）于１９９０年５月对我县农村中６０岁以上的老年人群进行测查，所调查的８个乡登记老人８５６４人，实查７８５６人（占９１．７％），其中男３２４６人，女４６１０人。年龄６７．０±９．１岁，文盲６０７６人，有脑血管病史者１３４０人，高血压病史者１０５８人，其他脑部疾病１０５人。按不同的文化程度划分智能受损的标准。结果平均为２０．５±２．５分，男２５．４±２．１分，女１８．９±１．５分，以男性显著较高。智能未受损７０４６人（８９．７％），轻度受损５３４人（６．８％），中度受损２２０人（２．８％），重度受损５６人（０．７％）。年龄愈大、受损愈重。有脑血管病史者受损也显著较重。作者认为ＨＤＳ设计简单、合理，应用方便。

bjective:To investigate intellectual impairment of elderly people in a rural area using Hasegawas Dementia Scale (HDS).Method:From 8564 registered elderly people in the county,7856 subjects were investigated with HDS in May 1990.The cut-off score of HDS was determined according to the education level:illiterate ≤15;primary school:≤ 19;middle school or above:≤ 23.Results:Among the 7856 subjects,3246 were male and 4610 were female.The average age was 67 0±9 1 years.6076 subjects were illiterate.The medical history was as follows:cerebrovascular diseases(1340),hypertension(1058)and other brain disorders(105).The average score of HDS was 20 5±2 1,with significant gender difference (male:25 4±2 1;female:18 9±1 5).89 7% of subjects had no intellectual impairment.6 8% revealed mild intellectual impairment,while 2 8% and 0 7% had moderate and severe impairment respectively.Intellectual impairment was positively correlated with age and past history of cerebrovascular disease.Discussion:HDS is a simple,convenient and reliable tool for screening dementia in Chinese populations.
