Ectopic pregnancy and prior induced abortion

A A Levin, S C Schoenbaum, P G Stubblefield

    American Journal of Public Health
    |March 1, 1982
    PubMed
    Summary

    Prior induced abortions may increase ectopic pregnancy risk. Women with multiple abortions or abortions plus pelvic inflammatory disease face higher risks, even after controlling for other factors.

    Area of Science:

    • Reproductive Health
    • Obstetrics & Gynecology
    • Epidemiology

    Background:

    • Ectopic pregnancy is a significant concern in reproductive health.
    • Understanding risk factors is crucial for prevention and early detection.

    Purpose of the Study:

    • To investigate the association between prior induced abortions and the risk of ectopic pregnancy.
    • To identify specific patterns of abortion history that may elevate ectopic pregnancy risk.

    Main Methods:

    • A case-control study comparing 85 women with ectopic pregnancy to 498 control subjects.
    • Analysis of prior pregnancy histories, including induced abortions.
    • Multivariate techniques were employed to adjust for confounding factors.

    Main Results:

    • A dose-dependent relationship was observed between the number of prior induced abortions and ectopic pregnancy risk.
    • Crude relative risks were 1.6 for one prior abortion and 4.0 for two or more.
    • Adjusted relative risks were 1.3 and 2.6, respectively, suggesting a persistent association.

    Conclusions:

    • Induced abortion may be a contributing risk factor for ectopic pregnancy.
    • The risk appears amplified in women with multiple abortions or co-occurring pelvic inflammatory disease.
