The objective of the study was to characterize the backgrounds of women who have repeat abortions.In a cross-sectional study of 259 women (mean age, 35.2 ± 5.6 years), the relation between adverse experiences in childhood and risk of having 2 or more abortions vs 0 or 1 abortion was examined. Self-reported adverse events occurring between the ages of 0 and 12 years were summed.Independent of confounding factors, women who experienced more abuse, personal safety, and total adverse events in childhood were more likely to have 2 or more abortions vs 0 abortions (odds ratio [OR], 2.56; 95% confidence interval [CI], 1.15–5.71; OR, 2.74; 95% CI, 1.29–5.82; and OR, 1.59; 95% CI, 1.21–2.09, respectively) and vs 1 abortion (OR, 5.83; 95% CI, 1.71–19.89; OR, 2.23; 95% CI, 1.03–4.81; and OR, 1.37; 95% CI, 1.04–1.81, respectively). Women who experienced more family disruption events in childhood were more likely to have 2 or more abortions vs 0 abortions (OR, 1.75; 95% CI, 1.14–2.69) but not vs 1 abortion (OR, 1.16; 95% CI, 0.79–1.70).Women who have repeat abortions are more likely to have experienced childhood adversity than those having 0 or 1 abortion.
