. RESULTADOS: A média de idade das mulheres de perdas foi mais elevada do que no Controle (32,3±6,3 versus 26,5±6,4 anos; p<0,01). Houve predomínio do consumo de bebidas alcoólicas no grupo de perdas (36,9 versus 22,1%; p=0,01), assim como no estado civil (93,2 versus 66,7%; p<0,01), no qual elas eram casadas ou viviam em união estável, respectivamente. O índice de massa corpórea pré-gestacional foi superior no grupo de perdas (26,9 versus 23,5%; p<0,01). Nos antecedentes obstétricos, 103 mulheres com perdas gestacionais relataram 334 gestações. Destas, 56 tiveram dois ou mais abortos no primeiro trimestre e em 31 delas, duas ou mais gestações evoluíram para abortos tardios/prematuros extremos. CONCLUSÕES: Mulheres com perdas recorrentes incluídas neste estudo tiveram alguns fatores de risco identificados, tais como a idade mais avançada e o índice de massa corpórea superior. As observações são coerentes com as propostas mais recentes a respeito de perdas recorrentes que consideram a inclusão das perdas em várias idades gestacionais.Abstract PURPOSE: 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 χ 2 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).
PURPOSE: To estimate the future pregnancy success rate in women with a history of recurrent pregnancy loss. METHODS: A retrospective cohort study including 103 women seen at a clinic for recurrent pregnancy loss (loss group) between January 2006 and December 2010 and a control group including 204 pregnant women seen at a low-risk prenatal care unit between May 2007 and April 2008. Both groups were seen in the university teaching hospital the Maternidade Climério de Oliveira, Salvador, Bahia, Brazil. Reproductive success rate was defined as an alive-birth, independent of gestational age at birth and survival after the neonatal period. Continuous variables Means and standard deviations (SD) were compared using Student's t-test and nominal variables proportions by Pearson χ 2 test. RESULTS: Out of 90 who conceived, 83 (91.2%) had reproductive success rate. There were more full-term pregnancies in the control than in the loss group (174/187; 92.1 versus 51/90; 56.7%; p<0.01). The prenatal visits number was satisfactory for 76 (85.4%) women in the loss group and 125 (61.3%) in the control (p<0.01). In this, the beginning of prenatal care was earlier (13.3; 4.2 versus 19.6; 6.9 weeks). During pregnancy, the loss group women increased the weight more than those in the control group (58.1 versus 46.6%; p=0.04). Although cervix cerclage was performed in 32/90 women in the loss group, the pregnancy duration mean was smaller (34.8 weeks; SD=5.6 versus 39.3 weeks; SD=1.6; p<0.01) than in the control group. Due to gestational complications, cesarean delivery predominated in the loss group (55/83; 64.7 versus 73/183; 39.5%; p<0.01). CONCLUSION: A very good reproductive success rate can be attributed to greater availability of healthcare services to receive pregnant women, through prenatal visits (scheduled or not), cervical cerclage performed on time, and available hospital care for the mother and newborn. . O número de consultas no pré-natal foi satisfatório para 76 (85,4%) mulheres no grupo de perdas e para 125 (61,3%) no grupo controle (p<0,01). Nestas, o início do pré-natal foi mais precoce (13,3; 4,2 versus 19,6; 6,9 semanas). O grupo de perdas teve ganho de peso acima do esperado mais frequentemente que as gestantes de baixo risco (58,1 versus 46,6%; p=0,04). Apesar de a cerclagem do colo uterino ter sido realizada em 32/90 mulheres com perdas, a duração média da gestação nestas foi menor (34,8
