contraceptive effectiveness |
0.01 sec. |
|
contraceptive effectiveness, the effectiveness of a method of contraception in preventing pregnancy. For clinical purposes it combines the theoretic effectiveness of the device, medication, or method and the use effectiveness. It is sometimes represented as a percentage but more accurately as the number of pregnancies per 100 woman-years. The average pregnancy rate for a couple who are sexually active and do not use contraceptives is equivalent to 85 pregnancies per 100 woman-years. A contraceptive method that results in a pregnancy rate of fewer than 10 pregnancies per 100 woman-years is considered highly effective. See also pregnancy rate, woman-year.

| Deborah Anderson had heard the urban legends about the contraceptive effectiveness of Coca-Cola products for years. The family planning literature contains numerous studies of contraceptive effectiveness among women, (4) use of contraceptives generally (and use of particular methods), (2,5) and factors affecting contraceptive use and nonuse. This higher level of contraceptive effectiveness would not only improve the lives of the women and their families, it would save roughly $200 million in government health care expenditures each year. |
