Measuring contraceptive prevalence among women who are at risk of pregnancy

摘要

Objectives: The contraceptive prevalence rate (CPR) is generally reported among in-union women ages 15-49. Here, union status and age serve as proxies for exposure to the risk of pregnancy. As a result of changing dynamics, age and union status proxies may be insufficient for determining the rate of contraceptive use among women at risk of pregnancy. Our objectives are to define a measure of contraceptive use among women at risk, to measure contraceptive use among such women and to compare this rate with conventional CPR.
