Pregnancy trends after abortion.
A series of women who aborted their pregnancies at King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia, over a period of 12 months (1 January 1992 to 3 December 1992), were followed up for 6-48 months afterwards to examine their pregnancy trends. Descriptive statistics for data presentation with Kaplan-Meier survivorship function estimates time from abortion to the next pregnancy and Cox proportional hazard regression analysis were used to identify prognostic factors. Eighty-one per cent of the women achieved pregnancy over a 4-year follow-up. The median time to pregnancy was 7.6 months, with a 95% confidence interval of 6.4-10.0 months. Age and nationality were found to be significant prognostic factors related to time to achieve a pregnancy. Furthermore, the outcome of the subsequent pregnancy was found to be statistically related to the number of previous abortions. There is a high chance of fertility after an abortion, with 75.2% of these occurring within the first 12 months of the post-abortion follow-up period and dwindling to only 4.1% by the end of 36 months. Using multivariate regression analysis, only age seemed to be an important determinant factor.
