title: [Epidemiological and obstetrics aspects in women with recurrent pregnancy losses at a public maternity in the Brazilian Northeast.]
abstract: OBJECTIVE
  To describe the epidemiologic and obstetric characteristics of women with recurrent miscarriages.
  
  
  METHODS
  A descriptive and analytical study whose inclusion criterion was every woman that was attended at the clinic for recurrent miscarriage (loss group), between January 2006 and December 2010. Patients that did not live in Salvador, Bahia, Brazil, and those who were not reached by telephone or whose number was not included in the medical record were not included. The Control Group consisted of 204 pregnant women seen at the low-risk prenatal care unit between May 2007 and April 2008. Women who did not accept to be interviewed and those with obstetric risk were excluded from the Control Group. The analyzed variables were: age, education, occupation, marital status, alcohol consumption, body mass index, obstetric history and the gestational age when the losses occurred. The SPSS 18.0 program was used for statistical analysis. Means and standard deviations of continuous variables were compared using the Student's t-test and the frequencies of the nominal variables were compared by the χ2 test.
  
  
  RESULTS
  The mean age of women in the loss group was higher than in the Control Group (32.3±6.3 versus 26.5±6.4 years old, p<0.01). Consumption of alcoholic beverages predominated in the loss group (36.9 versus 22.1%, p=0.01), as well as marital status (93.2 versus 66.7% were married or living in a stable union, p<0.01). The pre-pregnancy body mass index was higher in the loss group (26.9 versus 23.5%, p<0.01). Regarding obstetric history, 103 women with recurrent miscarriage reported 334 pregnancies. Fifty-six of them had 2 or more miscarriages in the first quarter and in 31 of them, 2 or more pregnancies progressed to late abortions/extremely preterm infants.
  
  
  CONCLUSIONS
  Some risk factors were identified in women with recurrent losses, such as more advanced age and higher body mass index. These observations agree with more recent proposals regarding recurrent losses that consider the inclusion of losses in various gestational ages.
