| 吸烟与冠心病的关系国内外均有许多报告,吸烟量与冠心病的病例对照研究国内外也有报告,但本文作者结合临床诊疗实践进行的吸烟量与冠心关系的病例对照研究仍然是可喜之举,其设计和方法也基本符合临床流行病学研究设计要求。本文是一项以医院为基础的病例对照研究,研究对象均经冠状动脉造影这一金标准检查,诊断方法可靠,错诊偏倚小 。 |

| Objective To study the prevalence and epidemiological characteristics of dementia and their major types in people aged 55 years and old in urban and rural area, Shanghai. Methods A sample with 17 018 residents aged 55 years and above from 22 urban and 14 rural communities was drawn through a stratified multiple stage cluster sampling. A door to door three phase procedure was used to investigate the prevalence of dementia. In 1997 and 1998, A brief memory testing by MMSE was administered to all participants. In phase 2, those who scored below the cutoff points and four percent of those whose score was in the normal range were interviewed to identify dementia through a set of diagnostic examinations according to the DSM IV criteria. In phase 3, a follow up program was conducted in 1998 for all persons who was involved in phase 2 to identify those with Alzheimer's dementia (AD) and vascular dementia (VaD) by NINCDS ADRDA and NINDS AIREN criteria. Results Of the targeted sample, 15 910 ( 94.2 %) were interviewed. The overall prevalence of dementia was 3.0% in individuals aged 55 years and above, 4.32 % in those aged 65 years old and 5.29 % in those aged 70 years and above. The age adjusted prevalence rates of dementia were 2.03 %, 3.78% and 5.48 % respectively among the age groups mentioned above. For AD the age adjusted prevalence rates were 1.37 %, 2.71 % and 4.13 % for individuals in above age groups. Of all types of dementia, AD was accounted 72%, followed by VaD the second. The prevalence of AD was 1.41 % in man comparing to 2.78 % in woman. The age specific prevalence of AD increased with age. Conclusion The prevalence of dementia was 3.0 % in individuals aged 55 years in urban and rural areas in Shanghai. Alzheimer's disease was more frequent than VaD. |
