Early medical abortion with methotrexate. Outcome and satisfaction among women aged 15-20 years
Background: We investigated the outcomes of women under age 21 who participated in a multi-center case series of early medical abortion using methotrexate and misoprostol.Methods: We enrolled 1973 women in a case series for medical abortion in the first seven weeks of pregnancy, using a standardized protocol and consent for methotrexate (50 mg/m(2)) and misoprostol (800 mg vaginally, repeated as needed).For this study, women who presented for abortion prior to their 21(st) birthday were compared to older women. Outcomes of abortion were classified as complete medical abortion (CMA) and suction curettage (SC). Secondary outcomes included symptoms. We did an exit interview assessing patient satisfaction during the first year of the study, and have exit interview data for approximately half of the women enrolled.We assessed the relationship of age and outcomes first by bivariate analysis using SAS (SAS Institute, Inc., Cary, NC). A multiple logistic regression model was constructed using age, gestational age, and measures of parity.Results: There were 219 women who were under 21 (18 under the age of 18). Compared to older women, adolescents presented for abortion at the same gestational ages. Compared to older women, younger women were less likely to have finished college (2.8% vs. 38. 7%), and were less likely to have had previous pregnancies (45.4% vs 76.6%) and live births (20.2% vs. 51.3%)The distribution of symptoms during abortion, such as bleeding and cramping, was the same across age groups; the only symptom which was more frequently found in younger women was headache.Overall younger women had a slightly higher rate of CMA as older women (90.2% vs. 86.5%). However, the multiple regression (MR) model did not show an effect of the woman's age on CMA. MR demonstrated an adverse effect of prior live birth, and advancing gestational age on rates of CMA; younger women were less likely to have had prior live births.Younger women were just as likely to report overall satisfaction (86.7% vs. 84.6%) with the abortion procedure and other questions of satisfaction, but were less likely to agree that the bleeding and cramping were acceptable. Conclusions: Younger women having medical abortion with methotrexate and misoprostol have similar outcomes and satisfaction levels as do older women. There is no reason to discourage adolescents who seek abortion from using a medical technique.
