title: [Risk factors associated to preclampsia].
abstract: BACKGROUND
  preeclampsia constitutes one of the main causes of maternal and perinatal morbidity and mortality. The aim was to identify the risk factors associated to the developmental of preeclampsia mild-moderate and severe, as well as the force of association of these factors in a hospital of second-level medical care.
  
  
  METHODS
  study of cases and controls, a relation 1:1, in women withdrawn of the Service of Gynecology and Obstetrics during 2004 to 2007. Pregnant women with more than 20 weeks gestation were included. In the cases group we included patients with diagnosis of preeclampsia mild-moderate or severe (corroborated clinical and laboratory). In the controls group that had a normal childbirth without pathology during the pregnancy.
  
  
  RESULTS
  42 cases and 42 controls. The average age was of 27 years. The associated risk factors were overweight, obesity, irregular prenatal control, short or long intergenesic period, history of caesarean or preeclampsia in previous pregnancies.
  
  
  CONCLUSIONS
  the knowledge of the risk factors will allow the accomplishment of preventive measures and decrease the fetal and maternal morbidity and mortality due to preeclampsia.
