Genetic epidemiological study of schizophrenia: reproduction behaviour.
Data from the Tomsk Epidemiological Register and epidemiological family sample were used to study the relationship between schizophrenics' reproductive behaviour (marital status and fertility rate), severity of ICD-9 schizophrenia and risk of illness among relatives of probands. The results are interpreted in terms of multifactorial threshold and single monolocus models. Their importance for the interpretation of epidemiological data (a change of prevalence rate, cohort effect and clinical polymorphism) is discussed.
