title: Childhood adversities and subsequent risk of one or multiple abortions.
abstract: Although many studies have found an association between childhood adversities and mental health disorders, few have examined whether childhood adversities are linked to having abortions. This research investigates the association between a range of childhood adversities and risk of abortion in part to identify which adversities should be considered when examining the association between abortion and subsequent mental health. Using the U.S. National Comorbidity Survey-Replication (NCS-R), we tested the association between 10 childhood adversities and risk of 0, 1, or multiple abortions among 1511 women ages 18-41. We employed multinomial logistic regression to examine the independent association between each childhood adversity and number of subsequent abortions, controlling for sociodemographic factors, total number of pregnancies, and each adversity. Women who had experienced two or more personal safety threats, one parental mental illness, or two or more parental mental illnesses while growing up were more likely subsequently to have multiple versus no abortions [Relative Risk Ratio (RRR) = 9.87, 95% CI: 2.45-39.72; OR = 2.81, 95% CI: 1.27-6.21; RRR = 5.28, 95% CI: 1.60-17.38, respectively], and multiple versus one abortion [RRR = 13.33, 95% CI: 2.48-71.68; RRR = 2.17, 95% CI: 1.03-4.56; RRR = 3.67, 95% CI: 1.15-11.76, respectively]. Women who had experienced childhood physical abuse were more likely to have one compared to no abortions [RRR = 2.00; 1.19-3.34]. These results suggest that some childhood adversities may partially explain the association between abortion and mental health. Accordingly, they should be considered in future research examining the link between abortion and mental health.
