title: [Anemic syndrome frequency in complicated obstetrical patients].
abstract: BACKGROUND
  The prevalence of anemia varies from country to country and there is not a trustworthy record.
  
  
  OBJECTIVE
  To determine the frequency of anemia in obstetric patients and the association among healthy pregnancy and aggregate complications.
  
  
  METHODS
  Was carried out as transversal, observational and comparative study. Obstetrical patients entered and responded in the period of a year, were formed a group with normal pregnancy and another with complicated pregnancy, with a total sample of 194 patients. In the statistical analysis was employed Student t test for independent groups, with value if p < 0.05.
  
  
  RESULTS
  When was included all patients from both groups of study a general frequency of anemia was found in 22.4%. Hematological stage from group with normal pregnancy was mild anemia in 16.9% and anemia moderated in 4.1% of the cases. The anemia degrees in the group with associated illness and pregnancy were mild anemia in 19.2% and moderated anemia in 4.2%. Not any case was found with severe anemia. The statistical analysis showed difference significant among both groups p < 0.05. The most frequently causes of the obstetrical morbidity were preeclampsia severe (22.6%), type 2 diabetes (13.9%), gestational diabetes (12.2%) and the remainder with other complications that include to the hypertiroidism, rheumatoid arthritis, lupus, asthma and vein deep thrombosis.
  
  
  CONCLUSIONS
  Frequency of anemia in this study was greater upon informing in the international literature. The obstetrical complication more frequently relates to diverse anemia degrees were the hypertensive stage during pregnancy. The anemia is presented with greater frequency in pregnancy patients with others associated illness.
