Family planning in Jordan: 1983 survey data.

Data from the 1983 fertility survey in Jordan indicate that 26 percent of married women were using contraceptives, reflecting a very small relative increase in use in the seven years before the survey. Only 5 percent of nonusers stated that they desired to use a method. Other data from the same survey suggest a potential demand for contraception, for spacing as well as limiting births, among those not using. For example, many recent pregnancies were reported to be unplanned. Also, among nonusers who did not desire to use a method, many stated they did not desire to become pregnant, yet were exposed to the risk of pregnancy. A pool of potential users exists who can be considered in need of contraception (i.e., fecund, not pregnant or desiring pregnancy, and not using contraceptives)--20 percent of all currently married, childbearing-age women--who may become contraceptive users as attitudes toward contraception change.

U.S. births and limit cycle models.

Lee's (1974) formal demographic feedback models summarize the implications for births and age-structure of neo-Malthusian theories of baby booms such as those of Easterlin. For some parameter values, such models imply sustained cycles, so-called "limit cycles", in births. Frauenthal and Swick recently reestimated a continuous-age version of Lee's basic cohort model with U.S. series and, contrary to Lee's original findings, concluded that "limit cycles oscillations have been occurring in U.S. births." This article disputes their conclusion, ascribing it to an inconsistency in detrending procedures. Furthermore, it corrects Lee's original conclusion by showing that his alternative period labor-force feedback model, estimated from U.S. series, leads to cycles of implausibly long period. This article thus reopens the question of whether any feedback model could account for the observed cycles in U.S. births.

Increasing contraceptive use in Bangladesh: the role of demand and supply factors.

This article analyzes the determinants of contraceptive use in Bangladesh, focusing on the roles of demand for additional children and of family planning service supply. Data from the Matlab Family Planning Health Services Project are used to examine the contributions of these factors to the difference in prevalence of modern contraceptive use between the project area and a control area served by the government family planning and health programs. Results of multivariate analysis deriving from the Easterlin synthesis framework show the importance of family planning supply factors in reducing psychic and resource costs of fertility regulation and in activating latent demand for contraception. Demand for birth limiting and for birth spacing emerge as important explanatory factors; demand for birth spacing is greater in the project area, and both demand measures exert a stronger effect on contraceptive behavior in that area.

[Analysis of natural family planning failures. In 7007 cycles of use].

MATERIALS AND METHODS: The analysis concerned 626 users using NFP in order to avoid a conception during a total of 6740 cycles. Participation in the study did not interfere with their plan of conception, and they were invited to behave, as far as possible, as though they ignored the study. Of these 626 couples, 530 were french, 61 belgian and 35 swiss. On the whole, 39.3% used birth control to limit births and 60.7% to space them. RESULTS: The observed pregnancy rates are 1.13, 6.47 and 17.58 for one year in actuarial method respectively for method, method + user and total pregnancy rate. The pregnancy rate was higher for women before 35 years (RR: 3.8; 95 p100 confidence interval: 1.4-10.3), during the six months after delivery (RR: 2.5; 1.0-4.6) and, of course, for couples with inprotected sexual intercourse in fertile phase (RR: 4.8; 2.1-11.2). DISCUSSION: NFP can be placed among methods of great theorical effectiveness. But pregnancies as a result of intercourses during the fertile phase despite its identification are frequent: couples have to be informed.
