A decade of change in contraceptive behaviour in Latin America: a multivariate decomposition analysis

This study relies heavily on World Fertility Survey and Demographic and Health Surveys data to examine recent trends and determinants of contraceptive use in five Latin American countries: Colombia, Dominican Republic, Ecuador, Mexico, and Peru. These countries experienced a substantial increase in contraceptive prevalence in the inter-survey period. Within countries, however, the increase was not equally shared by all social and demographic groups. The study found that relatively disadvantaged groups experienced greater gains in contraceptive use. Despite the prevailing tendency towards convergence, wide differentials in contraceptive behavior among social sectors still persist. A decomposition analysis based on logistic regression revealed that certain shifts in the population composition--i.e., increased proportion of urban and better educated women and a growing proportion of mothers who want to discontinue child-bearing--contributed substantially to the aggregate increase in contraceptive prevalence in most countries. Structural changes, understood as changes in the relations between the explanatory variables and the likelihood of using contraception, were also found to play a significant role in contraceptive use trends, particularly in Colombia.

Contraceptive use in Canada: 1984-1995

CONTEXT

In every country, contraceptive behavior has important implications for fertility and the prevalence of sexually transmitted diseases (STDs). There has been relatively little attention to contraceptive practices in Canada, however, particularly how patterns of method use may have changed.

METHODS

Data on contraceptive use were collected from 5,315 women in the 1984 Canadian Fertility Survey, and from 3,220 women and 3,449 men in the 1995 General Social Survey.

RESULTS

Among Canadian women aged 15-49, current contraceptive use declined from 69% to 60% between 1984 and 1995. Pill use dropped from 19% to 17%, and IUD use declined from 6% to 3%. However, during the same period, condom use increased from 6% to 10%; tubal ligation declined from 24% to 17%, while vasectomy increased. In addition, the proportion of women sterilized for reasons other than contraception rose between 1984 and 1995. Men were less likely to rely on sterilization than were women (31 % vs. 40%). Men reported higher levels of condom use (22%), but lower levels of pill use among their partners (9%), than did women (10% and 17%, respectively).

CONCLUSIONS

Contraceptive behavior in Canada is unique: The decline in contraceptive use over the last decade has left Canada's overall contraceptive prevalence among the lowest in the industrialized world, and the rate of sterilization among the highest These changes in contraceptive behavior complicate efforts to plan for social and health needs, particularly policy decisions focusing on reducing infections with STDs.

Oral contraceptive use before and after the latest pill scare in The Netherlands. Changes in oral contraceptive use and how users change

In October 1995, a "pill scare" developed in Europe. In the Netherlands, the recommendations given were 1) to not alarm women without risk for deep vein thrombosis (DVT), and 2) to be reserved in prescribing third generation oral contraceptives (OC) for young women who were beginning OC use. To determine whether there is a change in the prescription of third generation OC after the latest pill scare, prescription data from 1/10/94 to 1/10/96, covering a population of +/- 120,000 persons, were studied with respect to OC use before and after the pill scare. Trend analyses revealed a significant decline in third generation compared with total OC prescribing only in the youngest age category (p = 0.0034). Further, switch behavior was studied. Switches from third to second generation OC were more prevalent after the pill scare than before (odds ratio = 2.63; 95% confidence interval 1.84-3.75) and switches from second to third generation OC were significantly less prevalent after the pill scare. This indicates that Dutch prescribers have reacted to the pill scare in the way that the government recommended.

Education as policy: the impact of education on marriage, contraception, and fertility in Colombia, Peru, and Bolivia

Using data from the World Fertility and Demographic and Health Surveys of Colombia, Peru, and Bolivia, we model the effects of education on three demographic outcomes: the timing of first sexual union, contraceptive use, and fertility. These effects are examined over time and across geographic areas using a multivariate framework. We find substantial improvements in female educational attainment over the last fifty years and a strong relationship between education and the demographic outcomes. Each successive increment in education is associated with declines in the marriage rate, increased contraceptive use, and lower fertility. Education accounts for some of the changes over time in the demographic outcomes, but the pattern varies by outcome, time period, and geographic area. In support of the social diffusion hypothesis, our results indicate that educational differences in reproductive behavior are reduced as the level of development increases and societies pass through their demographic transition.

Trends in contraceptive use in the United States: 1982-1995

CONTEXT

Trends in contraceptive use have implications for shifts in pregnancy rates and birthrates and can inform clinical practice of changes in needs for contraceptive methods and services.

METHODS

Information on current contraceptive use was collected from a representative sample of women of reproductive age in the 1995 National Survey of Family Growth (NSFG). This information is compared with similar data from 1982 and 1988 to examine trends in use, both overall and in social and demographic subgroups.

RESULTS

The proportion of U.S. women using a contraceptive method rose from 56% in 1982 to 60% in 1988 and 64% in 1995. As in 1982 and 1988, female sterilization, the pill and the male condom were the most widely used methods in 1995. Between 1988 and 1995, the proportion of users relying on the pill decreased from 31% to 27%, while condom use rose from 15% to 20%. The largest decreases in pill use and the largest increases in condom use occurred among never-married women and among black women younger than 25. Reliance on the IUD dropped sharply among Hispanic women, while use of the diaphragm fell among college-educated white women.

CONCLUSIONS

The decline in pill and diaphragm use and the increase in reliance on condoms suggest that concerns about HIV and other sexually transmitted diseases are changing patterns of method use among unmarried women.

Does the timing of the first family planning visit still matter?

CONTEXT

The timing of a first family planning visit relative to first intercourse can affect the likelihood of an early unintended pregnancy.

METHODS

Nationally representative data from the 1982, 1988 and 1995 cycles of the National Survey of Family Growth were used to examine changes in the timing of first family planning visits and to explore the degree to which young women are now more likely than in the past to practice contraception independently of making a visit to a provider. Cox proportional hazards models were used to estimate how background variables, visit status and the initiation of contraceptive use affected risks of unintended pregnancy in the four years preceding each survey.

RESULTS

The proportion of women who waited a month or more after their first intercourse to see a provider grew slightly between 1978 and 1995, from 76% to 79%; women waited a median of 22 months after first intercourse in 1991-1995. Any contraceptive use at first intercourse increased among both women who delayed a first visit (from 51% to 75%) and among those whose first visit occurred before their first intercourse or within the same month (from 61% to 91%). Cox proportional hazards analysis suggests that the protective effect of a first family planning visit decreased over the period studied, due in part to the increase in early contraceptive use.

CONCLUSIONS

The importance of the first family planning visit appears to be declining, as sexually active young women who delay their first visit increasingly do so because they are already using a provider-independent method (primarily the condom). Thus, a multifaceted approach to providing family planning may now be needed, in which independent method use and visits to providers both play a role.

The long-term demographic role of community-based family planning in rural Bangladesh

Experimental studies demonstrating the effectiveness of nonclinical distribution of contraceptives are typically conducted in settings where contraceptive use is low and unmet need is extensive. Determining the long-term role of active outreach programs after initial demand is met represents an increasingly important policy issue in Asia, where contraceptive prevalence is high and fixed service points are conveniently available. This article examines the long-term rationale for household family planning in Bangladesh-where growing use of contraceptives, rapid fertility decline, and normative change in reproductive preferences are in progress, bringing into question the rationale for large-scale deployment of paid outreach workers. Longitudinal data are analyzed that record outreach encounters and contraceptive use dynamics in a large rural population. Findings demonstrate that outreach has a continuing impact on program effectiveness, even after a decade of household visitation. The policy implications of this finding are reviewed.

Recent evidence on trends and differentials in Bangladesh fertility: an update

A comparison of contraceptive and fertility data for 1985-91 with data for 1983 shows that fertility has continued to decline in Bangladesh, in all segments of society. The magnitude of decline varied according to educational level, region and urban-rural locality. The percentage decline in total marital fertility rate was somewhat higher among urban than rural residents; educated women showed greater declines than uneducated, increasing the overall educational differences in total fertility by 1991. Factors contributing to the recent decline in fertility are discussed.

Credit programs, women's empowerment, and contraceptive use in rural Bangladesh

This article presents findings of research addressing the question of how women's status affects fertility. The effects on contraceptive use of women's participation in rural credit programs and on their status or level of empowerment were examined. A woman's level of empowerment is defined here as a function of her relative physical mobility, economic security, ability to make various purchases on her own, freedom from domination and violence within her family, political and legal awareness, and participation in public protests and political campaigning. The main finding is that participation in both of the credit programs studied, those of Grameen Bank and Bangladesh Rural Advancement Committee (BRAC), is positively associated with women's level of empowerment. A positive effect on contraceptive use is discernible among both participants and nonparticipants in Grameen Bank villages. Participation in BRAC does not appear to affect contraceptive use.

The effect of price increases on contraceptive sales in Bangladesh

In April 1990, the prices of five brands of contraceptives in the Bangladesh social marketing project were increased, by an average of 60%. The impact on condom sales was immediate and severe, with sales for the following 12 months dropping by 46% from the average during the preceding 12 months. The effect on oral contraceptive sales was less dramatic: average sales in the year following the increases dropped slightly despite a previously established pattern of rapidly rising sales. There appears no reasonable combination of events other than the price increase itself to explain most of the difference.

Effect of child survival on contraceptive use in Bangladesh

A study in Bangladesh showed that couples who lost a child often stopped practising contraception in order to have another child. Logistic regression analysis revealed that contraceptive continuation was related to maternal age, parity, husband's education and the sex of the last child.

Conception of AIDS and its prevention among students in a Nigerian university

This study examines AIDS awareness, knowledge of transmission and prevention among students, who not only belong to the sexually active age bracket, but who are the future leaders of the nation. The student population was stratified into those in the health and non-health disciplines and an accidental sampling technique was used to obtain the respondents from the 2 strata. 60 students were interviewed from each stratum. A majority of the medical students, 58.3% as against 48.3% of the non-medical students, perceived AIDS as a dreadful disease that is sexually transmitted. Next among the non-medical students were those who felt that AIDS was God's punishment for man's sexual excesses (20.0%), while only 3.3% of the medical students gave that response. Of importance in the study is that none of the students attributed AIDS to mystical forces, an issue which could be linked to their educational exposure. Some students associated the disease with affluence, an issue that had been documented by other researchers. Another point worthy of note in the study is the fact that even though 89% and 61.2% of the medical and non-medical students, respectively, believed that AIDS can be prevented by the use of condoms, most of them were not favourably disposed towards the use of condoms. This study thus reveals an area that needs attention, ie that apart from emphasising the level of awareness, there should be a focus on how to effect behavioural change among a knowledgeable population.

Attitudes to AIDS and sexual behaviour among a cohort of medical students in Singapore

A survey conducted in 1990 among final year medical students found that most respondents had a good knowledge about AIDS and its routes of transmission. Among the 13.7% of respondents that were sexually active, it was noted that only 35% had used the condom before and that only 20% had used it in the most recent occasion of sexual intercourse. It was noted that only 30% of the sexually active had intention using the condom when they next have sexual intercourse despite the fact that 40% of them were having sexual intercourse with causal partners. Despite having a high knowledge of AIDS, medical students at the National University of Singapore have a low use of condoms.

Oral contraceptive pill use after an initial visit to a family planning clinic

A retrospective study of 1,311 women making initial family planning visits to metropolitan-area health department clinics found that many women switch methods or discontinue use in the first year following the clinic visits. Among a subgroup of women, most of whom selected the pill as their primary method and who used the pill for at least one of the months in the study period, almost half either changed methods or used no method at some point during a follow-up period averaging eight months. This includes 13 percent of women who made two or more changes. In addition, only 42 percent said they took a pill every day, and only half of these said they always took their pill at about the same time every day. Despite such irregularities, pill users were approximately one-third as likely to get pregnant during the study period as women making an initial family planning visit to a health department clinic who did not use the pill at all.

Reproductive health in Romania: reversing the Ceausescu legacy

As a result of the restrictive reproductive health policies enforced under the 25-year Ceausescu dictatorship, Romania ended the 1980s with the highest recorded maternal mortality of any country in Europe--159 deaths per 100,000 live births in 1989. An estimated 87 percent of these maternal deaths were caused by illegal and unsafe abortion. Under the Ceausescu regime, all contraceptive methods were forbidden and induced abortion was available only for women who met extremely narrow criteria. Immediately after the December 1989 revolution that overthrew Ceausescu, the new government removed restrictions on contraceptive use and legalized abortion. This legislative change has had beneficial effects on women's health, seen in the drop in maternal mortality in 1990 to 83 deaths per 100,000 live births--almost half the ratio in 1989. In addition, changes instituted since the revolution have led to the improved availability of reproductive health services and to the creation of new educational and training opportunities related to reproductive health services and to the creation of new educational and training opportunities related to reproductive health. The newly created contraceptive and abortion services have presented health system managers and policymakers with many challenges as they work to expand the availability of high-quality, comprehensive reproductive health care in a setting of economic hardship, political unrest, insufficient infrastructure, and outdated medical knowledge and practice.

Contraceptive use at first premarital intercourse: United States, 1965-1988

The proportion of U.S. women who used a contraceptive method at their first premarital intercourse rose from 47 percent in 1975-1979 to 65 percent in 1983-1988. Overall, and among non-Hispanic white women, this change resulted entirely from an increase in the use of condoms by their partners. The proportion of whites who used a condom at first premarital intercourse, for example, increased from 24 percent to 45 percent. Among blacks, condom use at first intercourse increased from 24 percent to 32 percent during that period, and pill use rose from 15 percent to 23 percent. Among all women, the method most often used at first intercourse during every period in the study was the condom, followed by the pill and withdrawal. The proportion of women using a method at first premarital intercourse varies strikingly according to individual characteristics. Among the various demographic subgroups, the proportion who use a method varies from 32 percent of Hispanic women to 68 percent of Jewish women. Whites are more likely to use a method than are blacks, and fundamentalist Prostestants are less likely to use a method than are other Protestants or Catholics. The proportion using a method is higher among women whose mothers completed high school than among those whose mothers did not. In addition, the proportion rises with age at first intercourse. Multiple logistic regression showed that the independent effects of Hispanic origin, Jewish or fundamentalist Protestant religious affiliation and the education of a woman's mother are large and significant.(ABSTRACT TRUNCATED AT 250 WORDS)

Trends in the contraceptive practices of women seeking abortions in the 1980s

The demographic features and contraceptive practices of 1000 women attending Parkview clinic of Wellington Hospital for termination of pregnancy were studied over an eight month period in 1988-9. Comparisons were made with a previous study at the same clinic in 1980-1. The overall abortion rate has increased from 6.8/1000 women in the Wellington statistical area in 1981 to 9.8 in 1989. The proportion of Pacific Island and Asian women presenting for abortions is high and has increased disproportionately between 1981 and 1989. The abortion rate has also increased in lower socioeconomic groups in 1989. The proportion of women using contraception at the time of conception increased from 50% in 1981 to 68.5% in 1989. The methods used by women presenting for abortion have changed significantly. There has been an increase in the proportion of women using condoms (from 13.3% to 36.2%) and the oral contraceptive pill from (14% to 21.4%).
