title: Hypertensive disorders in pregnancy: risk factors and epidemiologic analysis.
abstract: OBJECTIVE
  To measure the incidence of preeclampsia-eclampsia and its perinatal mortality as they appear in the two major ethnic groups in Thrace: Christian Orthodox and Muslims.
  
  
  METHODS
  Incidence and perinatal mortality of preeclampsia-eclampsia were studied retrospectively on all women managed in our clinic for hypertensive disorders in pregnancy who were delivered of a stillborn or healthy neonate between 1986 and 1999. We also compared the prevalence of certain risk factors of the disease as they appear in the above-mentioned distinct ethnic groups.
  
  
  RESULTS
  The total incidence of preeclampsia-eclampsia in Thrace was 2.3% and the total perinatal mortality 6.4%. Both variables presented higher values and severe preeclampsia-eclampsia had greater prevalence in the Muslim population. Most risk factors presented statistically significant differences between Christians and Muslims (chi2 test, p < 0.05).
  
  
  CONCLUSIONS
  There was an ethnic variation in most epidemiologic variables of hypertensive disorders in Thrace between Christians and Muslims.
