Perceptions of Birth Control Effectiveness and Barriers to Use: Impact on Unintended Pregnancy Risk in New Orleans.”

摘要: Using clinic-based data from inner-city New Orleans, we examine the effect of perceptions of method effectiveness and barriers to use on contraceptive behavior (comparing current family planning users vs. non-users or ineffective users who are currently pregnant) and on pregnancy intention (women with intended vs. unintended pregnancies). Multivariate regression analyses were performed separately for first pregnancy risk (never pregnant family planning users versus currently 1st time pregnant women) and for second pregnancy risk (family planning users with one pregnancy compared to currently second time pregnant women). Models also compare intended versus unintended pregnancy among currently first (or second) time pregnant women.For both first and second pregnancy risk, women who think that birth control is not or somewhat effective versus effective are significantly more likely to be currently pregnant. Also, women who report more barriers to condom use and to service use are significantly more likely to be currently pregnant than those who report fewer barriers. For the second pregnancy risk, women with intended first pregnancies are 2.85 (CI: 1.63-4.99) more likely to be family planning users and not pregnant than women with unintended first pregnancies. Women with unintended first pregnancies are 2.40 (CI: 1.08-5.36) times more likely to be having unintended second pregnancies compared to women with intended first pregnancies.
