Women at risk of pregnancy report higher levels of contraceptive use than the conventional contraceptive prevalence rate (CPR) indicates, according to a recent study. The CPR is generally reported among in-union women ages 15 to 49 years. Using data from the US 2011-2013 National Survey of Family Growth (NSFG), this study sought to compare actual contraceptive use among these women with conventional CPR in order to develop an alternative CPR (ACPR) measure. Researchers found:
- For measuring ACPR, it is best to limit sexual activity recency component to 4 weeks to minimize under-report of coital-specific methods.
- It is best to limit the contraceptive use components to “current use” rather than “use at last sex” to minimize under-report of permanent methods.
- 86% of women in the US at risk of pregnancy are currently using contraception.
