Contraceptive prevalence in Paraguay.

Contraceptive use, source of contraception, history of abortion, current pregnancy intention, and fertility rates are evaluated for a national sample of women using data from the Paraguay Contraceptive Prevalence Survey, conducted in 1977. The survey found that 15.5 percent of all women aged 15--44 and 23.6 percent of ever-married women were using effective contraceptive methods. The urban/rural difference in contraceptive use paralleled fertility differentials: over 40 percent of ever-married women were using contraception in Greater Asuncion and other urban areas compared with 15 percent in rural areas. Overall, the data indicate that high-parity rural women have the greatest need for family planning services in Paraguay.

Contraceptive practice and fertility in Thailand: results of the Third Contraceptive Prevalence Survey.

The Third Contraceptive Prevalence Survey in Thailand was conducted in 1984. Results indicate a continuation of the rapid rise in contraceptive use among married couples that has been taking place over the past 15 years. Prevalence levels are approaching those common in economically advanced countries. Sterilization is now the most common method, although a fairly broad range of other methods is also widely used. Only modest levels of unmet need for contraception for either limiting family size or spacing children now exist. Fertility rates have fallen since the previous survey, done three years earlier, but to a lesser extent than would be expected from the increased use of contraceptives. Family size preferences are concentrated at small family sizes. A comparison between the Buddhist majority and Moslem minority, made possible through a special sample design, reveals substantial differences between the two groups. Contraceptive use is lower and fertility levels and preferences are higher among Moslems than among Buddhists.

On the determination of contraceptive prevalence using health care utilization data.

A potential application of health care utilization databases is in the determination of contraceptive prevalence. A model linking specific factors concerning the utilization of modern methods of family planning has been developed to estimate contraceptive prevalence by age group for Saskatchewan. The limitations of these estimations of contraceptive prevalence are discussed.

Estimates of contraceptive prevalence based on service statistics and surveys in Gujarat State, India.

This report demonstrates that the estimates of contraceptive prevalence based on surveys are substantially lower than those based on the service statistics generated by the Indian family planning program. The reasons for this discrepancy were examined by contacting a subsample of acceptors recorded by female health workers as users in their registers. This inquiry indicated that the health workers themselves knew that 15-39 percent of the women who had been recorded as users of reversible methods were not really using them. About 19-27 percent of the recorded users of IUDs and only 3-4 percent of the recorded condom users confirmed use of the devices. Overall, the nonusers formed 59 and 64 percent of the recorded users contacted in Bharuch and Panchmahals districts, respectively. The estimates of nonuse of contraceptives in the follow-up survey are high enough to reconcile most of the observed discrepancy between the two sets of estimates of contraceptive prevalence.

An analysis of the empirical relationship between contraceptive prevalence and fertility in Bangladesh.

"This paper presents an empirical relationship between contraceptive prevalence and fertility [in Bangladesh]. It also shows how much the level of contraceptive practice is to be raised to reach a targeted level of fertility on the assumption that all other intermediate variables that influence the fertility remain constant. Regression analysis has been used to measure the relationship. A formula derived from Bongaarts's model is used to find the level of contraceptive practice required to reach a targeted fertility." Data are from a variety of sources, including four contraceptive prevalence surveys carried out between 1979 and 1985, the 1975 Bangladesh Fertility Survey, and official statistical sources.

Study of bias in antenatal clinic HIV-1 surveillance data in a high contraceptive prevalence population in sub-Saharan Africa.

OBJECTIVE: To describe patterns, sources and consequences of bias in antenatal clinic (ANC) HIV prevalence estimates in a high contraceptive prevalence population. BACKGROUND: HIV surveillance in Africa relies on data from pregnant women attending ANCs. HIV estimates from pregnant women understate female infection levels in low income, high fertility populations. Bias in high contraceptive use, delayed sexual debut populations remains undescribed. DESIGN AND METHOD: Comparison of parallel cross-sectional population and antenatal survey data from rural Zimbabwe, where 60% of women are recent contraceptive users. RESULTS: HIV prevalence in recently pregnant women (25.7%; n = 576) and all women (25.5%; n = 5138) is similar over the age-range 15-44 years. As in high fertility populations, HIV prevalence is higher in pregnant women at young ages and lower at older ages but the crossover point occurs later due to delayed sexual activity. HIV understatement at older ages due to HIV-associated infertility is mitigated by less HIV infection and less frequent ANC attendance in contraceptive users. The local ANC HIV prevalence estimate is lower [21.2%; n = 1215; risk ratio versus pregnant women in the general population, 0.8; 95% confidence interval (CI), 0.7-1.0], possibly because women from more remote areas are included. ANC estimates overstate the relative risk of HIV in more educated women (age-adjusted odds ratio, 1.1; 95% CI, 0.8-1.4 versus 0.7; 95% CI, 0.6-0.9). CONCLUSIONS: ANC estimates understate female HIV prevalence in this low fertility population but, here, the primary cause is not selection of pregnant women. ANC estimate adjustment procedures that control for contraceptive use and age at first sex are needed.

A simple method for estimating the contraceptive prevalence required to reach a fertility target.

This report describes and applies a procedure for estimating the increase in contraceptive prevalence that would have to occur to achieve specified future reductions in a population's fertility. This target-setting methodology is based on a previously developed analytic model for the relationship between fertility and its proximate determinants. The basic aggregate version of the estimation procedure, which is described in detail, requires relatively few input data, but it allows changes in the mix of contraceptive methods in future years. In extended versions of the model, age specificity and adjustments for given trends in the proximate determinants other than contraceptive use are introduced.

Contraceptive prevalence, reproductive health and our common future.

The 1980s will go into history as a decade of lost opportunities to increase contraceptive prevalence and improve reproductive health worldwide. As the decade closes, 500 million couples still have no access to fertility regulation, there are 30-50 million induced abortions each year, 15 million infant and child deaths (30% of all deaths worldwide), an estimated 250 million new cases of sexually transmitted diseases and 60-80 million infertile couples. One of the major problems is that many policy makers are still unimpressed with the global demographic reality. World population was less than 300 million 1991 years ago. It took some 1500 years to double this number by the time of the voyages of Columbus to America. The first billion was reached at the beginning of the last century and the second in the lifetime of the author, in 1927. Then it took less than 50 years to double this number to 4 billion by 1976. Global population is 5.3 billion today. In view of such figures, it is understandable that, historically, it was this demographic concern that in the 1960s persuaded many governments to support family planning programmes. During the subsequent decades, it was gradually recognized by developing country governments that family planning lowers infant, child and maternal mortality and morbidity and reduces the number of illegal abortions and their health hazards. Today, 52 developing country governments support family planning programmes for the demographic rationale, but 65 for the reproductive health and human rights rationale. Where do we go from here? That will mainly depend on the number of years it will take to reach replacement level of fertility (around 2.1 children per couple) worldwide. If the level is reached in 2010 (the low projection of the United Nations), global population will stabilize by the end of the 21st century at 8 billion; if it is reached in 2035 (medium projection), population will stabilize around 10 billion; however, if it is reached only in 2065 (high projection), the global population in 2100 will consist of more than 14 billion people, with major consequences on every walk of life. To restrict the final population to 10 billion, contraceptive prevalence must increase from 51% to 58% of married women of reproductive age before the year 2000 and to 71% by 2020, implying an increase from the present 350 million users to 500 and 800 million, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

Contraceptive prevalence in the slums of Rio de Janeiro.

A community-based family planning operations research project was undertaken in selected low income communities of Rio de Janeiro; project field work began in February 1982. Prevalence data were collected and service delivery strategies were tested, including home visits promoting family planning, home distribution of condoms, and the introduction of community family planning depots. A high baseline contraceptive prevalence rate (CPR) of 70.1 percent was found for nonpregnant women currently in union, as well as substantial use of the private sector for contraceptive supply, despite the presence of free or subsidized sources within the communities. However, the most economically disadvantaged subgroups made the greatest use of the subsidized sources. The provision of additional service delivery sites may have contributed to a small increase in contraceptive prevalence noted over the life of the project; however, the high baseline CPR precluded a large increase in contraceptive use as a result of the program.

Pakistan: contraceptive prevalence rate up.

Pakistan's low sociodemographic profile has changed dramatically since the 1994 International Conference on Population and Development, said the Minister for Population Welfare and Science and Technology, HE Begum Sayda Abida Hussain, during her statement at the Forum. Based on the population census of 1998, Pakistan has an annual population growth rate of 2.3%, she said. The decline may be attributed to changes in married patterns and a rapid reduction in marital fertility, she added. The contraceptive prevalence rate has gone up from only 2% in the early 1990s to about 27% in 1998. Meeting the demand for reproductive health services, reducing maternal, infant and child mortality, and promoting gender equality are high priorities for her government, she informed the participants in the Forum. In line with this priority, the Government of Pakistan has developed a new population and development policy and is working to improve the education and status of women, lower fertility, increase contraceptive prevalence, and reduce infant and maternal mortality, she told the meeting. Pakistan is expanding reproductive health services in the rural and urban areas through community-based organizations, she said. Some 50,000 women workers now provide counseling and other services to women at their doorstep. Before concluding her address, she called on donors' increased support for ICPD implementation. "The full implementation of the ICPD agenda requires resources that are beyond the capacity of a developing country like Pakistan," she said.

The World Fertility Survey and Contraceptive Prevalence Surveys: a comparison of substantive results.

This paper deals with the findings of the World Fertility Survey (WFS) and Contraceptive Prevalence Surveys (CPSs) in five areas of common interest: fertility, contraceptive use, measuring the effect of the availability of contraceptives on levels of use, the unmet need for family planning services, and breastfeeding. The comparisons have several implications for those designing surveys of fertility and family planning in developing countries, among them, that women should be asked for the dates of at least their last two births (not just the last birth as in the CPSs) in order to ensure accurate estimates of fertility and duration of breastfeeding.

Contraceptive prevalence: the influence of organized family planning programs.

Estimates of contraceptive prevalence for the period 1977-1983 are presented for 73 less developed countries. Socioeconomic conditions are associated with much of the variance in prevalence, but organized family planning programs strengthened this association significantly. The average percent of couples in the reproductive ages practicing fertility regulation is 26, with the range from 4 to 55 percent between the low and high socioeconomic groups of countries, and from 7 to 59 percent between groups of countries with very weak (if any) to strong family planning program effort.

Impact of social marketing on contraceptive prevalence and cost in Honduras.

In 1984, the Honduran Family Planning Association launched a contraceptive social marketing program by introducing the oral contraceptive, Perla. This report examines the impact of the program on overall oral contraceptive use, use by particular subgroups, source of supply, and costs. Although use of oral contraceptives increased only slightly over the period 1984-87 (from 12.7 percent to 13.4 percent among women in union aged 15-44), the social marketing program significantly increased its share of the oral contraceptive market (from 7 percent in 1984 to 15 percent in 1987, and from 20 percent to 40 percent of sales at pharmacies). For the Honduran Family Planning Association to have realized cost savings as a result of clients switching from community-based distribution programs and commercial supply sources to contraceptive social marketing programs, the association would have had to reallocate its resources. Instead, the number of distributors in the community-based distribution program increased, while the amount of couple-years of protection from oral contraceptives decreased.

Contraceptive prevalence and continuation: a longitudinal analysis of traditional and other method users in the Philippines.

Contraceptive prevalence rates and estimates of continuation rates are derived from unique longitudinal data on post-partum behaviour collected in the Cebu region of the Philippines. Continuation rates vary by base-line and time-varying socioeconomic characteristics for certain contraceptive methods and for using no contraception. Calendar rhythm users have a much lower relative continuation rate than has been found in cross-sectional samples. For women who use a contraceptive method, breast-feeding does not appear to influence contraceptive continuation, but for those who use no methods, breast-feeding appears to substitute for other forms of contraception. Profiles by socioeconomic characteristics of those who continue to use each type of contraceptive method and who use no method could be used to direct family planning programmes towards population sub-groups. The results suggest that for women wishing to postpone a pregnancy, a family planning programme aimed at the young and less educated could effectively increase contraceptive use and continuation.
