Contraceptive failure in the United States: revised estimates from the 1982 National Survey of Family Growth.

It is estimated that only about half of all abortions occurring during the period covered by the 1982 National Survey of Family Growth were actually reported in the survey; thus, contraceptive failure rates calculated from these data are almost certainly inaccurate. An attempt to correct for the underreporting of abortion indicates that actual 12-month use-failure rates are more than one-third higher than those calculated without taking abortion underreporting into account, with rates ranging from six percent for the pill to 14-16 percent for the condom, diaphragm and rhythm and to 26 percent for spermicides. Patterns of contraceptive failure are similar to those found in earlier studies.

Pill and IUD discontinuation in the United States, 1970-1975: the influence of the media.

Analysis of the 1975 National Fertility Study data on pill and IUD discontinuation shows an upward trend in discontinuation rates for both methods between 1970 and 1975, with particularly sharp increases in pill discontinuation starting in 1972. Almost 40 percent of pill discontinuation was attributable to problems of use; three-fifths of these problems were physical. About one-quarter of pill discontinuation was for reasons other than problems of use. The single most common of these was that the woman wanted to become pregnant. Almost 40 percent of IUD discontinuation was due to method-related problems; only 13 percent was due to the women's desire to become pregnant, a finding which suggests that women do not use this method for childspacing. Examination of the relationship between pill and IUD discontinuation and unfavorable news stories about these two methods reveals that after specific news events, discontinuation rates for both methods tend to increase. Rates climb for 5-6 months following specific unfavorable news stories, with peaks in the rate of change in discontinuation reached 3-5 months after a pill-related story and 2-4 months after an IUD-related story. General media coverage of the adverse effects of pill use in particular (where general coverage is defined as the cumulative number of pill articles appearing between 1970 and 1975) accounts for 34 percent of the variance in pill discontinuation rates. This correlation is strongly suggestive of a causal relationship between general mass media coverage of the adverse effects of the pill and discontinuation rates for this method.

Contraception and sterilization in the United States, 1965-1975.

Although the pill remains the most popular method of contraception among young married women, sterilization is now the method of choice among couples married a decade or more, as well as among couples who have had all the children they want. Indeed, contraceptive and medical sterilizations combined now comprise the most frequent barrier to conception among all married couples of reproductive age. Three-quarters of couples using contraception now use the most effective methods, the pill, sterilization or the IUD, and the trend data suggest a continuing increase in the reliance on such methods.

The secularization of U.S. Catholic birth control practices.

Except for sterilization, Catholic and non-Catholic contraceptive practices are now quite similar. Within several years, even sterilization will probably be adopted by the same proportions of Catholics as non-Catholics, and the rhythm method is destined to be of historical interest only. The wide gulf between official Catholic doctrine and the birth control behavior of Catholics can only deepen in the next few years.
