摘要
目的动态观察精神分裂症患病率的变化及可能的影响因素。方法于1993年在1982年调查过的7个地区开展流行病学调查,方法与1982年基本相同。结果精神分裂症终生患病率为6.55‰,时点患病率为5.31‰,与1982年比较有增高趋势(P>0.05);将经济水平分为上、中、下三等,以下等经济水平者的精神分裂症患病率为高。结论1993年出现的精神分裂症患病率变化,可能源于抽样误差,但不排除患者预期寿命延长因素。
Objective The purpose of this study was to investigate the possible changes in the prevalence of schizophrenia in seven areas in 1993, 11 years after the 1982 psychiatric epidemiological survey and to identify the possible factors that may influence these changes. Methods The same as that used in the 1982 psychiatric epidemiological survey over 12 areas. Results The 1993 survey uncovered a life time prevalence of 6.55‰ and time point prevalence of 5.31‰ for schizophrenia. Either the life time rate or time point rate were all of slightly higher than that of 1982 ( P >0.05). Additionally, there was a clear social drift process of schizophrenics to the negative social living conditions. Conclusion The slight higher but no statistic′s difference in the above comparison data is possibly due to either the sampling error or the cases accumulated and the extended life expectancy of schizophrenics. It is needed to urge more attention from the health administration to be paid to schizophrenics in the public health planning.
