Introduction: Since July 2007, abortion by women request up to 10 weeks of gestation is legal in Portugal. Between 2008 and 2012 there was an increase of 2% in the total number of legal abortions. In 2012, twenty percent of women had history of one previous abortion and 2% of the women had 2 abortions in the same year. Different factors (education level, marital status, economic level, number of children, access and contraception counseling) have been related to unwanted pregnancy and subsequent abortion. The factors that contribute for repeat abortion are not so well studied.
Objective: The aim of this study was to assess the factors that may influence the risk of repeated unwanted pregnancy and abortion.
Methods: Retrospective study of the clinical files of 4668 women (which had an unwanted pregnancy and requested for abortion at our institution, between 2007 and 2012). Two groups were created: Group 1-women with none previous abortion; Group 2-women with one or more previous abortion. Statistical analysis (Chi square and T Test) was performed to compare sociodemographic and planning family factors between the groups.
Results: Among a total of 4668 women, 4204 (90%) had no previous abortion (Group 1) and 464 (10%) had one or more abortion (Group 2). The mean age was 28,5 vs 30,9 years old (p= 0,0001). Data analysis showed: Superior education level in 51,7% vs 27,5% (p=0.000), married woman in 39,7% vs 42,2% (p=n.s),remunerated work in 58,6% vs 64,9% (p= 0,008), multiparous in 53,9% vs 69%(p=0,000),previous planning family consultation in 49,6 vs 48,9% (p=n.s), choice of long-acting reversible contraception (LARC) after abortion in 27,1% vs 45,9% ( p=0,0001).
Conclusions: Women with previous abortion are older than women with no previous abortion, multiparous and have a significantly better economic level but with lower education level. Other factors like marital status and previous family plannung consultation had no significant association with repeat abortion. After repeated unplanned pregnancy and abortion, women´s contraception choice favour LARC.
