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)

Some metabolic and hormonal changes in women using long acting injectable contraceptives.

Some metabolic and hormonal changes in women using longacting injectables as a contraceptive method were examined. The 2 main injectables utilized were depomedroxyprogesterone acetate (DMPA), given every 90 +or- 5 days, and norethisterone enanthate (NET/EN) injected every 60 +or- 5 days. None of the studied cases became pregnant during injectable use, indicating the high contraceptive efficacy of the method. No statistically significant changes were observed in hemoglobin, hematocrit, all protein fractions including albumin, alpha1, alpha2 beta, gamma immunoglobulins IgG, IgA, and IgM after 6 and 12 months in both groups of injectable users as compared with the preinjection values. Statistically significant suppression of the estimated hormones, Follitropin, Luteotropin, and Estradiol-17beta were detected in both groups of NET/EN and DMPA users, after 6 and 12 months, as compared with the preinjection values.

Implanon use in Thai women above the age of 35 years.

A prospective study of Implanon implant use in women older than 35 was conducted in Bangkok, Thailand. The purposes of this study were to evaluate the menstrual pattern and side effects of Implanon in 51 women followed for 6 months. Their mean age was 39.7 years. Most acceptors had completed primary school. No accidental pregnancies occurred in 6 months of use. The most common menstrual pattern in these acceptors was irregular bleeding followed by amenorrhea. The major side effect was irregular bleeding. There was no significant change in body weight, body mass index and diastolic blood pressure during the 6-month follow-up period, but systolic blood pressure declined. Implanon implant use is a safe and effective contraceptive method and should become another choice for contraception in women aged above 35 years who have contraindications for oral contraceptive use.

Efficacy and side effects of Norplant use in Thai women above the age of 35 years.

A prospective study of Norplant implant use in women aged above 35 years was conducted in Bangkok, Thailand. The purposes of this study were to evaluate the efficacy, menstrual patterns, and side effects of Norplant use in these women. A total of 100 women were recruited in a 1-year clinical study. Their mean age was 39.7 years. Most acceptors had completed secondary school. No accidental pregnancy occurred throughout the 1 year of use in this study. The most common menstrual pattern in these acceptors was amenorrhea followed by irregular bleeding. The major side effect was irregular bleeding. There was no significant change in systolic and diastolic blood pressure during the 1 year follow-up period. Thus, Norplant implant use in older women is a safe and effective contraceptive method. This should become another choice for contraception in women aged above 35 years who have contraindications for oral contraceptive use.

Provision of female sterilization in Ribeirao Preto, Sao Paulo, Brazil.

Forty percent of Brazilian married women from 15 to 49 years of age have undergone surgical sterilization. The 1988 Brazilian Constitution states that all scientifically proven contraceptive methods should be available to all citizens, but it was only in 1997 that specific family planning legislation was approved. This study examines physicians' perceptions and attitudes towards the current provision of female sterilization and its legal implications, as well as women's experience with obtaining and undergoing sterilization. The study design included: (1) an investigation of the hospitals and health professionals and (2) a survey of women sterilized in combination with cesarean delivery in 1998. The survey showed they had a median of 3 living children, 60.0% had been sterilized between 30 and 39 years of age, and 61.0% had paid for the procedure. Many women reported previous method failure and adverse effects with hormonal contraceptives. Women with less schooling and lower socioeconomic status had more children and had begun childbearing and had been sterilized at younger ages than women with more schooling and higher socioeconomic status. Inequalities related to reproduction were strongly associated with teenage pregnancy and inadequate knowledge about contraceptives.

Contraception and society.

When an idea meets the exigencies of an epoch, it becomes stronger than any form of political power and it becomes the common property of humankind. Such an idea was the development of contraceptives. In retrospect, the invention of contraceptives was as fundamental for the evolution of humankind as the invention of the wheel; today more than 550 million couples are using contraceptive methods. The large-scale use of contraceptives triggered the most powerful social revolutions of a century in reproductive health and gender equity, and substantially contributed to an unparalleled demographic change, characterized by a rapid aging of populations. One of the important reasons for population aging is a significant decline in fertility rates, resulting in gradually changing population structures with fewer and fewer children and more and more elderly persons. The causes underlying these demographic changes are complex and manifold; they reflect major societal changes of historical dimensions. Many of our institutions cater increasingly for a population structure that no longer exists. There is therefore an increasing need for institutional reforms in social security, health care, housing and education. In addition, several surveys conducted in the developed world have indicated an erosion of confidence in our basic institutions, e.g. courts and justice, the Church and Parliament. Whereas modem sociologists are concerned about an increase in crime, decrease in trust and depleted social capital, one can also observe an accelerated perception of our global destiny and a re-awakening of the moral impulse with a strong demand for increased transparency in public affairs. Also, various global communities have assumed a growing importance. It can be predicted that international professional communities, such as the European Society of Contraception, will play an increasingly important future role in influencing policies in general and health policies in particular. because of their profound commitment to the improvement of the human condition by the judicious use of new scientific information.

[Abortion after the 12th completed pregnancy week. Report of experience of a specialist commission].

In the GDR abruptio after 12th completed week of gestation is only allowed in cases of severe threat of health or danger for life. The decision is made by a group of specialists. Analysing the years 1972-1986 all the 135 cases worked up by the commission of the district hospital of Gera were evaluated. Reasons for delayed diagnosis of pregnancy and arguments for wanted abruptio were most interesting. To determine possible trends, the results were subdivided in two periods, 1972-1979 and 1980-1986. In the second period an unfavourable development was detected regarding number of cases, distribution of age, number of preceded pregnancies, and gestational age. A special problem was the group of juvenile pregnant women. Social arguments were dominating, especially problems regarding the partners. Associated with them, indecision on bearing to maturity was a predominant reason for delayed diagnosis of pregnancy followed by disorders of menstruation. Social arguments may be reduced about 80% by consequent contraception methods. Proper and consequent application of oral contraceptives could avoid 70% of the late diagnoses. Teenager should be brought to contraception by more confidence in their families.

Comparative trial of the contraceptive sponge and diaphragm. A preliminary report.

We evaluated the results from an ongoing comparative trial of the VLI contraceptive sponge and the diaphragm used with a spermicide. Among women who were not using vaginal contraceptives when enrolled in the study, the cumulative 12-month pregnancy rates were similar for the two contraceptive methods. Among women who were using vaginal contraceptives (principally diaphragms) when they were enrolled in the study, the group of women assigned to the diaphragm, as might be expected, had a significantly lower pregnancy rate. Rates of side effects and acceptability appeared to be similar for sponge and diaphragm users.

Timing of onset of contraceptive effectiveness in Depo-Provera users. II. Effects on ovarian function.

OBJECTIVE: To determine the timing of onset of contraceptive effectiveness after the first injection of 150 mg of depot medroxyprogesterone acetate (DMPA) administered between days 8 and 13 of the menstrual cycle. DESIGN: Descriptive, prospective study. SETTING: A tertiary university referral center. PATIENT(S): Thirty healthy women between 18 and 40 years of age. INTERVENTION: Volunteers were injected with DMPA between days 8 and 13 (5 women on each day) of the menstrual cycle. MAIN OUTCOME MEASURE(S): Ovarian function determined by serum levels of E2 and progesterone and follicular development evaluated by vaginal ultrasound. RESULT(S): In nine (30%) of 30 women studied, DMPA did not prevent ovulation. All ovulations occurred in women receiving DMPA between days 10 and 13 of the cycle. No woman who received injections on day 8 or 9 ovulated. Ovulation suppression was more effective in women with low ovarian activity. All ovulation occurred within 3 days after the injection. CONCLUSION: A back-up contraceptive method, used after the 7th day of the menstrual cycle, is recommended for up to 7 days after the first injection of DMPA.

Effectiveness of preabortion counseling on postabortion contraceptive use.

In a randomized trial, the effect of preabortion counseling was evaluated and contraceptive use postabortion described. The 420 women, who were assigned into either an intervention group (n = 210) or a control group (n = 210), were followed-up 4-6 months later, a total of 148 and 128 women in each respective group. No significant difference was found between the two groups regarding contraceptive use after abortion (86%, 85%), which indicates no immediate intervention effect. The women, in both groups, who had previously undergone abortion were less likely to use contraception. The main contraceptive methods used by intervention and control groups were oral contraceptives (61% and 58%, respectively) and injectables (12% and 11%). Choice of method was mainly based on women's prior perception of effectiveness and convenience of use. A majority of the women in both groups could not specify their contraceptive plans. A postrandomization inequality regarding age, education and parity in the two groups had, however, to be taken into account. Intensive contraceptive counseling before abortion may not be effective, but those who are at higher risk of unplanned pregnancy need special attention.

Metabolic response to starvation. II. Effects of sex steroid administration to pre- and postmenopausal women.

Premenopausal women become more ketotic than do men during short term starvation. The possible influence of female sex steroids on ketosis during an 84-hr fast was studied in premenopausal women receiving combined oral contraceptive steroids. The results were compared to age and weight-matched women on no steroid birth control regimen. Although concentrations of several plasma substrates, insulin, and glucagon were measured throughout the fast, no differences between groups were observed with the exception of the 36-hr interval. At this time total plasma ketones and betahydroxybutyrate were significantly higher in women receiving oral contraceptives. In a second study six postmenopausal women were investigated in a similar fashion during a 36-hr fast. The procedure was repeated following a 5 day treatment regimen of oral estradiol and medroxyprogesterone acetate. After sex steroid treatment, total plasma ketones and betahydroxybutyrate concentrations exceeded control values significantly at 36 hr while plasma alanine and free fatty acid levels were significantly lower. The results suggest that oral estrogen-progestin combinations increase the ketogenic response of pre- and postmenopausal women during the early phases of total starvation. This hormonal effect may explain, in part, why women are more sensitive to fasting than are men.

Coitus and contraception: the utility of data on sexual intercourse for family planning programs.

The Demographic and Health Surveys (DHS) program has included several questions on sexual intercourse in its model questionnaires that have been used in more than 25 surveys in Latin America, Africa, and Asia over the last five years. This article assesses the quality of the data on sexual intercourse for 12 DHS surveys and shows how these data may be useful for understanding contraceptive use dynamics and for organizing the management of family planning programs. The data show that there is considerable variation among countries in exposure to pregnancy prior to first marriage. Within marriage, the level of coital frequency varies with duration of marriage, fertility intentions, and type of contraceptive method used. Finally, in all countries there is some overlap between contraceptive use and sexual abstinence. This information can be useful in family planning programs for targeting particular populations, for assisting women to choose a method, and for assessing the effect of contraceptive use on fertility.

Choosing condoms.

Condoms for men are currently the most effective of the nonprescription contraceptive methods. They are readily available, simple to use, and relatively inexpensive, and they are not associated with major adverse effects. If used both properly and consistently, condoms can significantly reduce the risk of transmission of HIV and other STDs. The protection offered by the latex condom may be increased by the concurrent use of a vaginal foam or cream containing nonoxynol 9. The practicing pharmacist should know about the variety of condoms available, be able to explain their correct use to maximize effectiveness, and compare condom use with other types of contraceptives. The practitioner should be available to answer patrons' questions and provide counseling on contraceptives and "safe sex" practices.

Oral contraceptive use after conception in relation to the risk of congenital urinary tract anomalies.

The authors conducted a case-control study of the relation of OC use after conception to the occurrence of congenital urinary tract anomalies (CUTAs). Singleton CUTA cases with no known chromosomal abnormality from seven counties in western Washington State born during the period January 1, 1990-December 31, 1991 were identified through the Washington State Birth Defect Registry. Controls without birth defects were randomly selected from singleton births that occurred in the same year as the cases in five large hospitals in King County. Mothers of the 118 cases and 369 controls were interviewed to obtain their contraceptive history as well as other information. Mothers of nine cases (7.6%) and eight controls (2.2%) had taken OCs at some time during the pregnancy. After adjustment for birth year and county of maternal residence, OC use after conception was associated with an almost five-fold increased risk of having a baby with a CUTA [odds ratio (OR) = 4.8, 95 percent confidence interval (CI), 1.6-14.1] relative to no contraception at or after conception. Use of other contraceptive methods after conception was not related to the risk of CUTAs. OC use during the 3 or 6 months prior to the conception also was not associated with the risk of CUTAs. Further adjustment for sociodemographic factors, reproductive history, perinatal exposure to exogenous agents, and past OC use did not change the results, nor did restricting the analysis to residents of King County.(ABSTRACT TRUNCATED AT 250 WORDS)

Women on top: the relative influence of wives and husbands on contraceptive use in KwaZulu-Natal.

OBJECTIVES: The purpose of this paper is to examine the relative influence of husband and wife on contraceptive practice. METHODS: A cross-sectional survey was conducted among adult men and women in KwaZulu-Natal, South Africa. A matched file for 238 married or cohabiting couples was created. RESULTS: Knowledge of methods of contraception was virtually universal and attitudes to contraception were favorable both in men and women. A substantial proportion of men and women reported using a method of contraception. The wife's desire to stop childbearing was the most powerful predictor of contraceptive use among couples, after adjustment for possible confounders. The husband's approval (or not) of family planning and his preference for future childbearing were not significantly related to contraceptive use. CONCLUSION: Contraceptive use within marital and cohabiting unions is high and the wife's fertility preference was found to be a key determinant of use. This conclusion challenges conventional wisdom that men are the dominant decision-makers in fertility and family planning decisions.
