title: An incidence study of schizophrenia in India.
abstract: Under a WHO collaborative study, the Chandigarh center monitored two geographically defined populations over a 2-year period. Using helping-agency-coverage and other methods along with a set of specified criteria, 268 first-onset potentially schizophrenic cases were actively identified. Of these, 232 cases could be assessed in detail which included 209 schizophrenics as per specified ICD-9 or Catego criteria. The annual incidence rates obtained were 4.4 and 3.8 per 10,000 for rural and urban areas, respectively. The rural cohort had a higher incidence for each of the three diagnostic definitions. In the urban cohort, sex and diagnostic definition did not affect the incidence. In the rural cohort, females had a lower incidence for Catego S+ and a higher incidence for other diagnostic definitions.
