Use-effectiveness and client satisfaction in six centers teaching the Billings Ovulation Method.

Use-effectiveness of the Billings Ovulation Method (OM) is reported for 1139 clients from six centers who were followed for at least 24 months. Method failure rates were 1% when calculated by either Pearl formula or life table analysis. Combined method and user failure rates were 20% when calculated with the Pearl formula, and 16% at 12 months and 23% at 24 months by life table analysis. Pregnancy rates were higher for couples using OM alone, than for couples using OM in combination with additional fertility awareness methods or together with barrier methods. The difference was significant when estimated by the Pearl formula but not when analyzed by the life table. The emotional implications underlying the apparent contradiction between a desire to avoid pregnancy and the deliberate coital use of fertile days are reflected in the differences between method and user failure rates, the high client satisfaction levels reported with "user failure," and 56% continuation rate at 24 months. The will require in-depth exploration.

A survey of contraceptive use and unplanned pregnancy in Perth, Western Australia.

Contraceptive use and unplanned pregnancy were studied in a stratified cluster sample of 1,511 couples with women aged 16 to 44 years resident in metropolitan Perth in 1988. Twenty-one couples were excluded from analysis owing to missing data. The proportion of couples using contraception was 76.8 per cent (1,144 of 1,490), and all but three of the remaining couples gave a reason for nonuse. Among users, surgical sterilisation made up 42.3 per cent (484 of 1,144) of all methods, with a slight predominance of tubal ligation over vasectomy. Oral contraceptives accounted for just over half of nonsurgical methods. Comparisons with a Victorian survey performed in 1978 suggested that surgical methods and condom use may have increased, whereas use of oral contraceptives and intrauterine devices may have fallen. Unplanned pregnancies conceived during the 12 months before the interview affected 3.4 per cent (51 of 1,490) of respondents. The incidence of unplanned pregnancy was four times higher in couples with inconsistent usage patterns of contraception.

A clinical study comparing the performance of three IUCDs (Multiload Copper 250, Copper T 200, and Lippes Loop C).

300 Women at Cairo's Al-Zahraa Hospital, using 1 of 3 different IUds (CuT 200, multiload Cu250, and Lippes loop size C) to compare the rate of complications encountered among the 3 groups. Failed insertion was highest among the Cu T200 group with a rate of 3.24/HWY, hundred woman years. Accidental pregnancy was highest among that group as well. With a rate 2.16/HWY compared with 1.10/HWY among the ML Cu250 group and none among the Lippes Loop group. The spontaneous expulsion rate was the same for the Cu T200 and Lippes Loop, i.e., the rate was 4.32/HWY and 4.44/HWY for the 2 groups, respectively, compared with 1.10.HWY for the ML Cu250. The highest removal rate because of pain or bleeding was encountered among the ML Cu250 users, i.e., the rate was 4.41.HWY compared with 3.33/HWY among the Lippes Loop group and 1.08/HWY for the Cu T200 group. The overall failure rate was 8.82/HWY for ML Cu250, 11.89/HWY for Cu T200, and 11.10/HWY for the Lippes Loop group.

Contraceptive paths toward the reduction of unintended pregnancy and abortion.

Based on data from the 1982 National Survey of Family Growth, exposure to the risk of unintended pregnancy is classified by use of specific contraceptive methods and by nonuse, and average rates of unintended pregnancy are estimated for each type of exposure. Three hypothetical models of improved contraceptive practice are then applied to the data for all women and for age, race and marital-status subgroups. The first two models assume increases in the use of some existing contraceptive methods, but only the second model additionally assumes the introduction of new methods. The third model assumes the complete elimination of nonuse of contraception. These models yield different estimates of the reduction in unintended pregnancy rates which are illustrated for various age-groups, for whites and blacks and for married and unmarried women. Among all women aged 15-44, the changes assumed by Model I imply a 32 percent reduction in unintended pregnancy; Model II implies a 56 percent reduction; and Model III implies a 57 percent reduction. The implied reductions in abortion are in a similar range.

Unintended pregnancies in the United States, 1970--1972.

There were about 2.0--2.3 million unintended pregnancies in the United States each year during the early 1970s. Within this framework, the rapid rise in the number of abortions since 1973, to 1.3 million in 1977, is quite predictable.
