The Effect of Spontaneous Abortion on Outcome of Subsequent pregnancy

Spontaneous abortion is the most common complication of pregnancy. Women with abortion are always worried about the outcome of their next pregnancy. This study was designed to evaluate the effects of spontaneous abortion on outcome of next pregnancy. This case – control study was performed at moatazedi Hospital in Kermanshah, west of Iran during 2003-2006.Six hundred and five women with history of one spontaneous abortion were selected as the case group and 1210 women with history of one term delivery were selected as the control group. The age range of the women was 20-35 years. Various variables including placenta abruption, placenta previa, preterm labour, still birth, premature rupture of membranes, pre-eclampsia, low birth weight, fetal malformations, fetal presentation, intrauterine growth retardation (IUGR), type of delivery, and Apgar score were studied. Data were analyzed by SPSS software version 11.5. Statistical tests including chi-square, Fischer, Lon, and independent t were used. Mean age of the patients in the case group was 24.6 versus 23.5 years for the women in the control group. Of the variables, only preterm labour (P=0.034) and cesarean section (p=0.034) were significantly more common in the case group. There was no significant difference between the two groups for the other variables. There is a higher risk for pregnancy complications in women with the history of previous spontaneous abortion. Such women have to be under close observation with meticulous perinatal care during the pregnancy.
