Contraceptive use patterns among US women who had abortions were similar in the month in which they became pregnant and 14 years later, with changes in method use mirroring changes in contraceptive use among the larger population of women. Using secondary data from the 2000 (n=10,015) and 2014 (n=8,177) Abortion Patient Surveys, patients were asked which contraceptive methods they had last used and when they had stopped or they were still using them. The primary outcome variable was type of contraceptive method used in the month the pregnancy began. Among the findings:
- In both years slightly more than half of patients reported they had used a contraceptive method in the month they became pregnant.
- The most commonly reported methods used in the month the pregnancy began were condoms, followed by the pill.
- There was a statistically significant increase in the proportion of abortion patients who reported using long-acting reversible methods in the month they got pregnant, with the estimated number of abortions attributed to these users greater in 2014 vs 2000 (9,500 vs 1,800).
