title: No relationship between risk of schizophrenia and prenatal exposure to stress during the Six-Day War or Yom Kippur War in Israel.
abstract: OBJECTIVE
  Maternal stress during pregnancy is a possible risk factor for schizophrenia in the offspring. Using data from the Israel Psychiatric Registry we examined the impact of wars in Israel.
  
  
  METHODS
  Retrospective birth cohort study.
  
  
  RESULTS
  Relative risks for cohorts exposed to Six-Day War and Yom Kippur War were 0.98 (95% CI: 0.85-1.13) and 1.00 (0.86-1.16).
  
  
  CONCLUSIONS
  The evidence for maternal stress as a risk factor for schizophrenia remains insufficient.
