The 2002 Canadian Contraception Study: Part I

OBJECTIVES

To investigate the contraception and sexual health-related awareness, attitudes, and practices of a representative sample of Canadian women of childbearing age.

METHODS

A self-report survey was mailed to a national sample of 3345 women, aged 15 to 44 years, who were members of a pre-recruited market research panel. Survey questions and methodology were similar to 3 previous Canadian Contraception Studies, allowing for description of current patterns of behaviours and beliefs and comparison of trends over time.

RESULTS

Of 3345 women contacted, 1582 returned completed surveys, for a response rate of 47.3%. Responses were weighted to represent Canadian women by region, age, and marital status on the basis of current census data. Eighty-six percent of women sampled had ever had sexual intercourse and 78% were currently sexually active. Women's familiarity with oral contraceptives and condoms as methods of contraception was high (96% and 93%, respectively), but familiarity with other methods was much lower (sterilization, 62%; withdrawal, 59%; the morning-after pill, 57%; intrauterine devices, 50%; depot [injectable] medroxyprogesterone acetate, 38%). A very favourable opinion was held by 63% of respondents concerning oral contraceptives, by 38% concerning condoms, and by 39% and 28% concerning male and female sterilization, respectively. Among respondents who have ever had sexual intercourse, the most frequently used current methods were oral contraceptives (32%), condoms (21%), male sterilization (15%), female sterilization (8%), and withdrawal (6%). Nine percent of these respondents reported using no method of contraception at all. The currently reported rate of female sterilization is the lowest ever recorded in Canada. Survey results show that adherence to contraceptive methods is a challenge for many women and their partners, and that risk of sexually transmitted disease is an ongoing concern.

CONCLUSION

This study provides a wide-ranging examination of contraception awareness, beliefs, and use among Canadian women that may provide guidance for clinical and public health practice. Part 1 of this report describes the methodology of the 2002 Canadian Contraception Study and the overall results of this study; Part 2 considers results pertaining specifically to adolescent women and women in their later reproductive years, reports on indicators of women's sexual function and reproductive health history, describes approaches to addressing challenges in contraception counselling, and presents data concerning trends in Canadian women's awareness and use of contraception over the past 2 decades.

Contraception continuation rates and reasons for discontinuation in Zahedan, Islamic Republic of Iran

We evaluated contraception continuation rates and discontinuation reasons in Zahedan among 1741 women from 1998-2000. By Kaplan-Meier technique continuation rates were 92% for low dose combined hormonal oral contraceptives (OC), 86% for a levonorgestrel-releasing implant, 82% for intrauterine devices (IUD) and 53% for medroxyprogesterone acetate at the first year. After 3 years, continuation was 78% for levonorgestrel implant, 70% for OC, 60% for IUD and 44% for medroxyprogesterone acetate. The commonest reason for discontinuing OC and medroxyprogesterone acetate was changing method; for IUD and levonorgestrel-releasing implant, the commonest reason was side-effects. By Cox regression model, continuation rate and contraceptive type were significantly related to health centre.

Trends in reproductive behavior among young single women in Colombia and Peru: 1985-1999

Using "calendar" data for single women aged 15-24 from successive Demographic and Health Surveys (DHS) conducted in Colombia and Peru during the 1990s, we document trends, year by year, in sexual activity, the use of contraceptives, and subsequent reproductive outcomes. We provide evidence of the important and hitherto largely untapped potential of DHS calendar data to draw complete sexual and reproductive profiles when data from various surveys are integrated. Over the period 1985-1999, young single women in both Colombia and Peru became sexually active at younger ages. The use of contraceptives, especially the use of condoms, increased but did not fully offset the rise in sexual activity, and thus the incidence of premarital conceptions rose among young single women. In both countries, sharp declines occurred in the proportion of premaritally conceived births that were reported as being wanted.

Trends and determinants of contraceptive method choice in Kenya

This study uses data from the 1989, 1993, and 1998 Kenya Demographic and Health Surveys to examine trends and determinants of contraceptive method choice in Kenya. The analysis, based on two-level multinomial regression models, shows that, over time, the use of modern contraceptive methods, especially long-term methods, is higher in urban than in rural areas, whereas the pattern is reversed for traditional methods. Use of barrier methods among unmarried women is steadily rising, but the levels remain disappointingly low, particularly in view of the HIV/AIDS epidemic in Kenya. One striking result from this analysis is the dramatic rise in the use of injectables. Of particular program relevance is the notably higher levels of use of injectables among rural women, women whose partners disapprove of family planning, uneducated women, and those less frequently exposed to family planning media messages, compared with their counterparts who have better access to services and greater exposure to family planning information.

Changes in contraceptive use in Vietnam

This analysis used data, primarily from the 1997 Vietnamese Demographic and Health Survey (VN-DHS 1997), to determine the changes in contraceptive use in Vietnam. A descriptive analysis of individual, household and community characteristics was made to obtain a general description of contraceptive use. Multinomial logistic regression analyses were also performed on the currently married in (a) a sample of all women and (b) only those women who live in rural areas, to identify the strength of association that each variable has with the use of modern contraceptives. The use of any contraceptive method and the use of modern methods increased from 1988 to 1997. The primary contraceptive method utilized is the IUD and its use has increased substantially from 1988 to 1997. Younger women (aged 15-24) were less likely to use any contraceptive method. Women not desiring additional children were significantly more likely to use contraceptive methods than those desiring more children. Education has a clear impact on both contraceptive knowledge and use by women, with higher educated women being more likely to use a contraceptive method. Illiterate women with no formal education were significantly less likely to use modern methods of contraception. Differentials in contraceptive use exist regarding place of residence. Urban women are more likely than rural women to use contraception, but the difference is not large. Women living in mountainous areas are less likely to use contraception, compared with women living in the lowlands. Living standards, especially the availability of electricity in the community, have a large effect on the methods of contraception adopted by women. Religion is not strongly related to the contraceptive behaviour of women. There were significant differences in the use of contraceptives in communities with good quality of care, with increased contraceptive use corresponding to the increase in availability of family planning workers at communes, provision of counselling services at health facilities, and the volume of mass media family planning messages.

Contraceptive behaviour of teenagers requesting abortion

OBJECTIVE

To examine the contraceptive use of teenage girls requesting abortion.

STUDY DESIGN

A questionnaire survey was made concerning contraceptive use, awareness and the attitude toward contraceptives. The Mantel-Haenszel test was applied to compare contraceptive determinants between teenagers (<20 years old) and older women.

RESULTS

The use of reliable contraceptive methods was significantly less frequent among the teenagers than among the older counterparts, but this difference was much more significant (P<0.001) between those who requested abortion (OR=0.44) than between the controls (OR=0.51). The knowledge about emergency contraceptive pills was similarly significantly poorer between the teenagers in the abortion group (P<0.001) relative to the older women (OR=0.07) and the teenagers in the control group (OR=0.10). Financial means was not a significant determinant in the choice of contraceptives.

CONCLUSION

To prevent unwanted pregnancy among teenagers, the media, the family, the school and health-care providers should focus on sexual education and information.

New contraceptive choices across reproductive life

The range of contraceptive options and consumer awareness of new contraceptive methods have both increased significantly over the past 10 years. New methods available in Australia include lower-dose oral contraceptive pills, new oral progestogens, progestogen implants, a progestogen-bearing intrauterine device and polyurethane female condoms. Contraceptive options which may soon be introduced in Australia include novel methods of administering combined (oestrogen-progestogen) contraception, such as dermal patches and vaginal rings.

Evidence of changes in sexual behaviours among male factory workers in Ethiopia

OBJECTIVE

To assess changes in sexual behaviours among male factory workers in Ethiopia.

DESIGN

Open cohort studies in two factories near Addis Ababa.

DATA AND METHODS

At intake and biannual follow-up visits, data were collected on sexual behaviours including casual sex, sex with commercial sex workers (CSW), condom use, and history of sexually transmitted diseases (STDs) as indicated by genital discharge and genital ulcer. Health education, HIV testing, and counselling were offered to all participants.

RESULTS

Between February 1997 and December 1999, 1124 males were enrolled in the two cohort studies. At intake, the prevalence of casual sex in the past year, sex with CSWs, condom use with the last casual partner, history of genital discharge in the past 5 years, and history of genital ulcer in the past 5 years were 9.7, 43.4, 38.8 (Akaki site only), 10.6 and 2.1%, respectively. At the Wonji site, the intake prevalence of casual sex, sex with CSW, and history of genital discharge decreased significantly by calendar year between 1997 and 1999. At both sites combined, between the first and the fourth follow-up visits, there was a decline in the proportion of males reporting recent casual sex (from 17.5 to 3.5%, < 0.001), sex with CSWs (from 11.2 to 0.75%, < 0.001), and genital discharge (from 2.1 to 0.6%, = 0.004).

CONCLUSION

There was a decline over time in risky sexual behaviours reported by cohort participants. Part of this decline occurred independently of cohort interventions.

Trends in adolescent sexual risk behaviors

Many societies worldwide are faced with an increase in adolescent pregnancy, rape, sexual abuse and sexually transmitted disease due to different sexual behaviors and sometimes lack of responsible sexual behaviors. The World Health Organization and the Surgeon General of the United States Government have called for action to this serious public health issue. In this short communication data from the United States, Canada and Israel is presented with a call for a professional response to this public health challenge.

Differences in teenage pregnancy rates among five developed countries: the roles of sexual activity and contraceptive use

CONTEXT

Adolescent pregnancy, birth, abortion and sexually transmitted disease (STD) rates are much higher in the United States than in most other developed countries.

METHODS

Government statistics or nationally representative survey data were supplemented with data collected by private organizations or for regional or local populations to conduct studies of adolescent births, abortions, sexual activity and contraceptive use in Canada, the United States, Sweden, France and Great Britain.

RESULTS

Adolescent childbearing is more common in the United States (22% of women reported having had a child before age 20) than in Great Britain (15%), Canada (11%), France (6%) and Sweden (4%); differences are even greater for births to younger teenagers. A lower proportion of teenage pregnancies are resolved through abortion in the United States than in the other countries; however, because of their high pregnancy rate, U.S. teenagers have the highest abortion rate. The age of sexual debut varies little across countries, yet American teenagers are the most likely to have multiple partners. A greater proportion of U.S. women reported no contraceptive use at either first or recent intercourse (25% and 20%, respectively) than reported nonuse in France (11% and 12%, respectively), Great Britain (21% and 4%, respectively) and Sweden (22% and 7%, respectively).

CONCLUSIONS

Data on contraceptive use are more important than data on sexual activity in explaining variation in levels of adolescent pregnancy and childbearing among the five developed countries; however, the higher level of multiple sexual partnership among American teenagers may help explain their higher STD rates.

AIDS and contraception. Unanticipated effects of AIDS prevention campaigns

BACKGROUND

This study addresses the effects of AIDS prevention campaigns on contraceptive practices among the general population in France. Comparisons of contraceptive practices and condom use by women aged 18-49 years were performed in two national population-based surveys (n = 559 in 1994, n = 731 in 1998).

RESULTS

A decrease in the proportion of women aged 20-24 with multiple partners reporting the use of contraception was observed between 1994 and 1998. In the same time, there was an increase in the use of condoms to prevent AIDS.

CONCLUSION

Findings suggest that single-risk prevention campaigns on AIDS may lead some women to pay less attention to the risk of unwanted pregnancy.

Sexual activity and contraceptive practices among teenagers in the United States, 1988 and 1995

OBJECTIVES

This report presents national estimates of sexual experience, contraceptive use, and selected aspects of sexual behavior among never-married males and females aged 15-19 years in the United States. Data are presented for the years 1988 and 1995 according to age, race and Hispanic origin, progress in school, and other relevant characteristics. Tables present trends over time as well as comparisons between subgroups.

METHODS

Descriptive tables of numbers and percents are presented and interpreted. Data for females are from the National Survey of Family Growth, and data for males are from the National Survey of Adolescent Males.

RESULTS

About half of all never-married teenagers, about 17.5 million, had had sexual intercourse at least once in 1995. For male teenagers, this represents a decline since 1988, and for females, the proportion was stable across the two time points. The proportion of teen females who had sex before age 15 years increased. In 1995, 29 percent of females and 19 percent of males had unprotected recent sexual intercourse. About one-quarter of teens used no contraceptives during their first sexual intercourse. The condom remained the most popular method of contraception. Although teenagers' use of oral contraceptives dropped between 1988 and 1995, use of injectable and implant contraceptives began. Teenagers with more highly educated mothers, mothers who delayed their first birth beyond age 19 years, those from two-parent families, and those whose schooling was on schedule, were less likely to engage in sexual risk behaviors. These teenagers, along with those who were Protestant, also experienced the largest improvements across time in sexual risk behaviors.

Patterns of contraceptive use in 5 European countries. European Study Group on Infertility and Subfecundity

OBJECTIVES

The use of contraception in Denmark, Germany, Poland, Italy, and Spain is described.

METHODS

Data were drawn from a population-based cross-sectional study, the European Study of Infertility and Subfecundity. Interviews were conducted with 6630 women aged 25 to 44 years. Logistic regression was used to estimate the effect of factors associated with contraceptive use.

RESULTS

Residents of Northern European countries tended to use more effective methods of contraception than residents of Southern European countries. The use of contraception was generally more common among single women, the more highly educated, those with children, and those with a previous induced abortion. These characteristics were also the main determinants of the use of more effective methods. Periodic abstinence and withdrawal were more common among older women.

CONCLUSIONS

The European countries are in different phases of contraceptive practice: in Northern and Western Europe, use of more modern methods has been stable over the past 10 years, whereas these methods are less common in Southern and Eastern Europe. The results suggest the need for information, education, and provision of contraceptive services in Eastern and Southern Europe.

Sexual and fertility behaviors of American females aged 15-19 years: 1985, 1990, and 1995

OBJECTIVES

This study characterized changes in sexual and reproductive behaviors from 1985 through 1995 among American females aged 15 to 19 years and related these changes to family factors.

METHODS

Nationally representative sample survey data from the 1995 National Survey of Family Growth were analyzed with Weibull hazards models of age at first intercourse and first pregnancy and with logistic regression models of contraceptive use at first intercourse and pregnancy outcome.

RESULTS

Improvements in the family socioeconomic situations of young women have lessened the risk of teen motherhood, while changes in family structure have increased the risk. Young women whose parents have more than a high school education, who live with both parents, and who attend church delay the timing of first sexual intercourse and are more likely to use a contraceptive.

CONCLUSIONS

The trend of increases in teenage motherhood has ended owing to a halt in increases in the proportion of sexually active young women and substantial improvement in contraception, with the greatest improvements among those from advantageous family situations.

Social-demographic influence on first birth interval in China, 1980-1992

This study examines the delay between first marriage and first live birth in China among a sample of women who married between 1980 and 1992. Most couples in China only use contraception after the first child is born. Most sample women had their first child within 2 years of marriage. However, there are significant rural-urban differences in the first birth interval, indicating that there was most probably deliberate fertility regulation after marriage among many urban couples. Survival analysis shows that place of residence, level of education, age at first marriage and marriage cohort affect the first birth interval.

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.

Trends in teenage pregnancy in England and Wales: how can we explain them?

Teenage pregnancy is associated with adverse social and physical outcomes for both mother and child. We drew on various sources--birth and abortion statistics from the Office for National Statistics, data from the National Survey of Sexual Attitudes and Lifestyles, and routinely collected data from family planning clinics--to identify trends in England and Wales and their possible determinants. The rate of teenage sexual activity has increased steadily and consistently over the past four decades, whilst the rate of teenage fertility has shown greater variation. When the teenage fertility rate is calculated against the denominator of sexually active women, rather than the total sample of teenage women, the underlying trend in teenage fertility over the past four decades has been downwards, though not consistently so. Fluctuations in the teenage fertility rate seem to track intervention-related factors such as access to, and use of, contraceptive services and the general climate surrounding the sexual health of young people.

Contraceptive practices and trends in France

CONTEXT

Contraceptive use has been legal in France for the past 30 years, and patterns of use changed substantially from the 1960s to the 1980s. Given the rapidity with which use patterns change and the possible impact of rising concern about infection with HIV and other sexually transmitted diseases, it is important to determine trends of contraceptive practice into the 1990s.

METHODS

A total of 5,900 French households were selected in 1994 for inclusion in the Fertility and Family Survey. Respondents were questioned about their contraceptive use patterns and family formation status. The results were compared with those of comparable surveys conducted in 1978 and 1988.

RESULTS

Two-thirds of French women used some form of reversible contraceptive method in 1994. Oral contraceptive use has grown steadily in France: About 40% of women aged 20-44 reported using the pill alone or combined with another method in 1994, compared with 34% in 1988 and 28% in 1978. Condom use has also been on the rise: Nearly 8% of women were using condoms alone or combined with another method in 1994, up from 5% in 1988 and 6% in 1978. IUD use has declined from 19% in 1988 to 16% in 1994, and both male and female sterilizations remain rare.

CONCLUSIONS

Contraceptive behavior in France appears unique among developed countries, with fairly high levels of oral contraceptive use--even among older women--relatively high levels of IUD use and little reliance on either male or female sterilization. As with other countries, however, condom use has climbed in recent years, and is especially common at first intercourse.

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.

The initiation of adolescent sexual and contraceptive behavior during changing times

This paper examines changes in the initiation of adolescent sexual and contraceptive behavior in the United States between 1978 and 1988. Since a number of contextual changes occurred during this time period including a focusing of public attention on adolescent pregnancy along with the widespread publicity surrounding AIDS, we expected that the response to these events not only would change over time, but would also vary across social groups. Using data from Cycles III and IV of the National Survey of Family Growth, we find that the overall population patterns of earlier initiation of sexual intercourse and increased use of condoms at first intercourse are not found in all segments of the population. In general, the effects of race, religion, mother's education, and age changed during this time period. The long-term trend of younger age at first intercourse was halted for Blacks, and reversed for White, fundamentalist Protestants, but continued for all other Whites. Overall, patterns throughout the decade suggest that pressures from parents, religious groups, and others either lead to a later age at first intercourse, or use of contraception, but not both. A notable exception is that increased maternal education leads to both a later age at first intercourse and a higher likelihood of using contraception at first intercourse.

[The medicosocial aspects of contraception for teenagers]

The authors study and examine the influence of some medical and social factors on the teenagers use of contraceptives. The study is based on the questionnaires fulfill by 568 teenagers (aged 13-19). In the enquêtes are shown the role of the family status of the parents the involvement of the family and the school in the sex education, and also are indicated the favorite teenager's contraceptive methods. The positive attitude on contraception and on this kind of researches is very characteristic for 94% of the analyzed teenagers. The authors made a conclusion on optimizing the use of modern contraceptives for teenagers.

Trends in risk behavior and HIV seroprevalence in heterosexual injection drug users in San Francisco, 1986-1992

We examine changes and stability in risk behaviors and HIV-1 seroprevalence among heterosexual injection drug users (IDUs) over 13 cross-sectional surveys, 1986-1992. Interviews (n = 5,956) were conducted with IDUs in street settings and drug detoxification clinics over 6.5 years, and respondents were tested for HIV-1 antibody. Trends in use of condoms and bleach and HIV seroprevalence were assessed using multiple logistic and linear regression analyses. The percentage of time condoms were reportedly used during intercourse among men increased from 4.5% to 31.0%. Among the declining population of IDUs who reported needle sharing, reported use of bleach increased from 3% to 89%. Significant changes in use of bleach 100% of the time were reported: 29.8% in 1988, 52.8% in 1990, and 40.0% in 1992. HIV seroprevalence doubled from 7% in 1986 to 14% in 1987. Post-1987 fluctuations in HIV seroprevalence were not significant. Significant changes in risk behaviors among IDUs were reported over the study period. These changes coincided with the implementation of HIV prevention in San Francisco, including outreach programs, HIV testing and counseling, bleach distribution, and syringe exchange. The moderate and stable rate of HIV seroprevalence beginning in 1987 parallels self-reported reductions in risk behavior.

The clandestine epidemic: the practice of unsafe abortion in Latin America

In Latin America, induced abortion is the fourth most commonly used method of fertility regulation. Estimates of the number of induced abortions performed each year in Latin America range from 2.7 to 7.4 million, or from 10 to 27 percent of all abortions performed in the developing world. Because of restrictive laws, nearly all of these abortions, except for those performed in Barbados, Belize, and Cuba, are clandestine and unsafe, and their sequelae are the principal cause of death among women of reproductive age. One of every three to five unsafe abortions leads to hospitalization, resulting in inordinate consumption of scarce and costly health-system resources. Increased contraceptive prevalence and restrictive abortion laws have not decreased clandestine practices. This article addresses how the epidemic of unsafe abortion might be challenged. Recommendations include providing safer outpatient treatment and strengthening family planning programs to improve women's contraceptive use and their access to information and to safe pregnancy termination procedures. In addition, existing laws and policies governing legal abortion can be applied to their fullest extent, indications for legal abortion can be more broadly interpreted, and legal constraints on abortion practices can be officially relaxed.

Have the AIDS campaigns changed the pattern of contraceptive usage among adolescents?

In 1984--just before the extensive public information about prevention of HIV infection by the use of the condom (the AIDS campaigns)--personal interviews about sexual experiences and use of contraception were obtained in random samples of 16-20 year old Danes. The investigation was repeated in 1989 addressing the issue of whether the behavior of adolescents regarding sexual intercourse and use of contraception has changed. In 1984 in all 286 females (respondent rate = 75.3%) and 336 males (respondent rate = 77.8%) agreed to be interviewed. The second investigation in 1989 involved new cohorts of 16-20 year olds and here 359 females (respondent rate = 77.9%) and 400 males (respondent rate = 76.3%) participated. In 1984 approximately 20% and in 1989 approximately 10% reported no use of contraception at first sexual intercourse. In both investigations oral contraception (OC) and condom were by far the predominant methods mentioned. In 1984 38.1% of females and 34.4% of males used OC and 37.2% of females and 42.1% of males employed condom. In 1989 26.7% of females and 30.8% of males used OC and 64.8% of females and 62.1% of males employed condom. No sex difference in the distribution of the various contraceptive methods could be revealed. From 1984 to 1989 the prevalence of condom increased significantly. In the first investigation 15.9% of sexually experienced females reported no present use of contraception. The most frequently used device was OC (62.7%). The second investigation collected information about contraception employed at the most recent sexual intercourse from both females and males. Approximately 5% of both sexes mentioned no use of contraception.(ABSTRACT TRUNCATED AT 250 WORDS)

Contraceptive use in Matlab, Bangladesh in 1990: levels, trends, and explanations

The results of a 1990 knowledge, attitudes, and practice survey in Matlab, Bangladesh, indicate that contraceptive prevalence has risen to 57 percent in the maternal and child health/family planning project area. Between 1984 and 1990 significant increases were registered in the proportions of women using contraceptives for the purposes of spacing and limiting births. By 1990 fertility control in the intervention area had become so widely diffused that educational differentials in contraceptive practice were no longer evident. Although significant gains in contraceptive use were also evident in the neighboring comparison area during this period, at 27 percent, prevalence there still remained substantially below the levels in the intervention area. The disparity in contraceptive use between the two areas is adequately explained neither by differences in socioeconomic conditions nor in the demand for family planning, but rather by differences in the intensity, coverage, and overall quality of their family planning programs.

Trends in sexual behaviour and HIV testing among women presenting at a genitourinary medicine clinic during the advent of AIDS

Changes in female sexual behaviour with the advent of AIDS and safer sex campaigns were studied. Subjects were drawn from a wide social spectrum of women attending an STD clinic in West London where there is a high prevalence of HIV infection among homosexual men. Between 1982 and 1989, 4224 women answered a self-administered questionnaire: women who reported more than one sexual partner in the previous year fell from 56.9% in 1982 to 51.8% in 1989 (p = 0.003). Anal intercourse showed no change and was reported by 8.8% in 1982 and 9.4% in 1989 (p = 0.8). Oral intercourse increased from 36.9% in 1982 to 44.7% in 1989 (p = 0.001). Condom use for contraception increased from 3.6% in 1982 to 16.2% in 1989 (p less than 0.001). Between 1987 and 1989, 35.6% of 3199 women reported having non-regular partners with no significant trend over this period; these women had earlier coitarche (17.0 years cf 17.9 years), many more partners (p less than 0.0001) and more practised anal (p = 0.007) and oral (p less than 0.0001) intercourse. However, frequent use of condoms doubled from 23.6% in 1987 to 47.6% in 1989. During this period, the prevalence of antibody to HIV (anti-HIV) remained unchanged (0.27-0.37%), but more women declined to be tested. Anonymised testing showed that none of those who refused consent for named testing was anti-HIV positive. It is concluded that significant changes in female sexual behaviour have taken place with the advent of AIDS but there has been no evidence of heterosexual spread beyond the confines of well defined risk behaviours. Risks of the magnitude reported in homosexual men were not found in heterosexual women.

Evidence for a change in behaviour among heterosexuals in Amsterdam under the influence of AIDS

In determining the effectiveness of AIDS preventive measures among heterosexuals, trends in visits to two clinics for sexually transmitted diseases (STD) in Amsterdam between 1982 and 1989 are described. Also, data on sexual behaviour are presented that were collected in a sample of 635 heterosexual women and 947 heterosexual men at one of the clinics between September 1986 and December 1988. In 1987, when in The Netherlands for the first time extensive publicity was given to the risk of heterosexual transmission of the human immunodeficiency virus, the numbers of male and female heterosexual attenders started to decline. Exceptions to this general decline were men of Turkish nationality and foreign prostitutes, each group showing a continuing increase. At the same time, the numbers of customers reported by prostitutes in the sample declined markedly between 1986 and 1988, from a median of 35 to 15 per month (p = 0.001). Condom use with casual contacts generally increased in the sample period. We conclude that the publicity given to "heterosexual AIDS"--contributed to by the national AIDS prevention campaign--apparently led to a considerable decrease in the number of risky contacts of heterosexuals in Amsterdam in 1987 and 1988. This does not seem to apply to men with Turkish nationality. In 1989 a change appeared in several subgroups when the number of visitors started to rise. Also, the probability of an STD diagnosis increased in male attenders. This may indicate a change in the tendency towards safer sexual behaviour.

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%).

Contraceptive use in random samples of Greenlandic and Danish women--changes from 1986 to 1988

As part of a study of risk factors for cervical cancer, the possible change was assessed in the use of condoms after AIDS campaigns. In 1986, samples of 800 women aged 20-39 years were drawn at random from Nuuk/Godthåb (Greenland) and Nykøbing Falster (Denmark). A total of 586 and 661 women were interviewed in Greenland and Denmark, respectively. In 1988, new random samples of 150 women were drawn from the same areas. Totally, 129 Greenlandic and 126 Danish women were included in the study. From 1986 to 1988 the prevalence of ever having used condoms increased significantly among Greenlandic women aged 20-29, whereas no statistically significant changes were observed in Denmark. This pattern was independent of the lifetime number of sexual partners. Neither in Greenland nor in Denmark did the mean lifetime number of sexual partners change from 1986 to 1988.

Patterns of contraceptive use in the United States: the importance of religious factors

Previous research has shown that the major religious communities in the US have all shifted their expected family size downward but significant differences in contraceptive use styles continue to characterize Catholics, Protestants, Jews, and those of no religious affiliation. This paper examines data from Cycle IV of the National Survey of Family Growth (1988) to extend the time period covered by previous research by comparing the emerging contraceptive use patterns and fertility expectations among women in the late 1980s with earlier cohorts from previous national studies, beginning in the 1960s. The categories of religious affiliation are extended to include specific religious denominations (fundamentalist Protestants, Baptists, and other denominations, as well as Mormons) and include measures of religiosity--church attendance, the extent of receiving communion among Catholics, and attendance at church-related schools. These data are examined for blacks, Hispanics, and non-Hispanic whites. The analysis suggests how religious affiliation and religiosity continue to be important factors in the contraceptive paths to low fertility under general conditions of controlled fertility and in the context of secularization.

Different contraceptive practices: use of contraceptives in Finland and other Nordic countries in the 1970s and 1980s

Contraceptive practices, especially oral contraceptive and intrauterine device use, were studied in four Nordic countries by recalculating published and unpublished data from previous surveys and statistics and by collecting new data from Finland. The sales of oral contraceptives were presented in defined daily doses, and the percentages of women using oral contraceptives were estimated from them. The percentages of intrauterine device users were calculated taking into account the number of intrauterine devices sold each year and the continuation of use from previous years. The results of the surveys were reanalysed. We found clear differences in contraceptive practices. Oral contraceptive use was most prevalent in Sweden and Denmark, and, especially at the end of the 1970s, Finnish intrauterine device use was very high. In the 1980s the differences dimished somewhat. These disparities in culturally and economically similar countries indicate that further research is needed to evaluate the factors influencing contraceptive practices.

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.

[Has family planning behavior in West Germany changed since 1985?]

A survey on the family planning behaviour in the Federal Republic of Germany was conducted by interviewers of the EMNID institute in 1985 (n = 1267) and 1989 (n = 950). The survey was carried out with women of 15 to 45 years of age. It was the aim of the 1989 study, to look into changes of the last four years generally and with regard to the increasing knowledge about AIDS. As the use of a combination of family planning methods has significantly increased in 1989, the overall percentage went very much beyond 100% (1985: 106.1% vs 1989: 138.5%). Hence, for comparison of the figures, we omitted any sociodemographic weighting. For each method, the percentage of the users is reported independently of any additional method used. The figures (%) for use of reversible methods of contraception 1985 vs 1989 were as follows: the pill (52.2/61.9), condom (10.0/24.8), IUD (14.1/10.8), withdrawal (5.8/6.6), mini-pill (1.7/6.5), NFP (8.8/6.0), locally applied chemical device (2.6/5.2), vaginal diaphragm (3.0/3.0). The frequency of sterilisation was 6.9 vs 5.7%; the frequency of unwanted pregnancies 26.6 vs 20.9%. 12.3% of the women aged 18-45 years stated, that family planning behaviour has changed in the last two years. 1/3 of these declared, that AIDS has played an important part in their decision. Answers to other questions are compared 1985 vs 1989, like "reasons for selecting a particular method", "need for use of contraceptives", "frequency of unwanted pregnancies" and "importance of natural methods".
