The incidence rate of an illness is a vital epidemiological measure for investigating etiology. Incidence estimates of schizophrenia from different parts of the world have shown variations, due to differences in the diagnostic criteria, measurement techniques and operational definitions used. In contrast to the prevalence studies in India, incidence surveys haw been sparse and the rates obtained relatively higher as compared to the west. As part of an ICMR Longitudinal Study of Functional Psychoses in an urban community in Madras, the incidence of schizophrenia was estimated in the slums. The case finding methods included a door to door survey and a leakage study. Cases defined using standardized diagnostic criteria, were identified using IPSS and PSE. The incidence rate was 0.21/1,000 by the community survey and 0.41/1,000 by the leakage study. This paper describes the study and discusses its relevance in India.
发病率是研究病因的重要流行病学指标。由于诊断标准、测量技术和操作定义的不同，来自世界不同地区的精神分裂症发病率估计存在差异。与印度的患病率研究相比，发病率调查很少，获得的发病率相对较高。作为 ICMR 在马德拉斯一个城市社区进行的功能性精神病纵向研究的一部分，在贫民窟中估算了精神分裂症的发病率。病例发现方法包括挨家挨户的调查和漏报研究。使用标准化诊断标准定义的病例，使用 IPSS 和 PSE 进行识别。社区调查的发病率为 0.21/1000，漏报研究的发病率为 0.41/1000。本文描述了这项研究，并讨论了它在印度的相关性。
