A MEDICAL RECORD LINKAGE ANALYSIS OF ABORTION UNDERREPORTING

Inaccuracy in women's reports of their abortion histories affects many areas of interest to reproductive health professionals and researches . The identification of characteristics that affect the accuracy of re porting is essential for the improvement of data collection methods. A comparison of the medical records of 104 American women aged 27-30 in 1990-1991 with their self-reported abortion histories revealed that 1 9% of these women failed to report one or more abortions. Results of l ogistic regression analysis indicated that nonwhite women were 3.3 tim es as likely as whites to underreport. With each additional year that had elapsed since the first recorded abortion, women became somewhat m ore likely to underreport (odds ratio of 1.3), while each additional y ear of a woman's education slightly decreased the likelihood of underr eporting (odds ratio of 0.7).
