Contraception usage over the age of 40 in Polish female population aged 45 - 54.

OBJECTIVE: Analysis of particular contraception method usage over the age of 40 as declared by Polish women aged 45-54 according to their education level and place of residence. METHOD: The research was conducted with help of a standardized questionnaire in a Polish nationwide representative sample of women aged 45-54 years (n = 1083) in April 2004. RESULTS: 28% of sexually active women over 40 years old did not use any contraception methods. Most of them were country dwellers (41%), a lower proportion lived in small/moderate towns (27%), and a significantly lower percentage was made by big city dwellers (14%). Among the most popular contraception methods the respondents indicated coitus interruptus (32%), condoms (30%) and the calendar method (26%). Oral contraception was used by 12% of women. CONCLUSION: A considerable percentage of sexually active women aged more than 40 years do not use any contraception method at all or use unreliable methods. Highly reliable methods (condoms, contraception pills) are much more popular among city dwellers. Contraception pills are used by twice as many city dwellers as rural dwellers (16% versus 8%) and by 12% of women from small/moderate towns. Rates of condom usage are also differentiated and vary from 42% in big cities to 26-27% in rural areas and small/moderate towns. Although poor availability of the contraception pill might explain some differences in its usage, it is difficult to quote this factor in the case of condoms.

Contraceptive practices before and after an intervention promoting condom use to prevent HIV infection and other sexually transmitted diseases among women--selected U.S. sites, 1993-1995.

Because heterosexual contact is the most common mode of human immunodeficiency virus (HIV) transmission among women, development of effective strategies to reduce sexually transmitted HIV infection is critical. In addition, because most women at risk for HIV infection are reproductive aged (14-44 years), effective use of contraceptives is important to prevent unintended pregnancies. Latex condoms used by males, when used consistently and correctly, are highly effective at reducing the risk for HIV infection and other sexually transmitted diseases (STDs); however, hormonal contraceptive methods or surgical sterilization are more effective for preventing pregnancy. One possible effect of encouraging women to use condoms for HIV/STD prevention with their male partners is that women may discontinue use of hormonal contraceptive methods. To assess whether encouraging women to use condoms for HIV/STD prevention affects their contraceptive practices, CDC analyzed longitudinal data on contraceptive methods and condom use for HIV/STD prevention that were collected as part of a randomized trial evaluating HIV-counseling methods during August 1993-June 1995. This report summarizes the findings of the analysis, which indicate that, among reproductive-aged women who were encouraged to use condoms for HIV/STD prevention, consistent condom use for HIV/STD prevention increased among women using each contraceptive method studied. In addition, most women using hormonal contraceptive methods continued to use them after the intervention, and the overall proportion of women protected against pregnancy increased.

Contraception after thirty-five.

Our knowledge about the safety, the incidence of side effects, and the effectiveness of contraceptive methods for women in premenopause, or during the last decade of their reproductive life, has not been a primary interest for research and development in fertility control. The main purpose of trials for the evaluation of new contraceptive methods is to test their effectiveness, and therefore only women below 38 years of age are accepted. Furthermore, when new methods are being tested, only healthy women are accepted, and those having health problems of almost any kind are excluded. Therefore our knowledge about the contraceptive methods in women over 40 years of age is scanty and comes from trials with a long-lasting follow-up on healthy women who can use the method without problems until they are 45 or reach menopause. We have very limited reported information on the use of contraceptives by women who have cardiovascular disease, diabetes, liver problems, etc. Therefore the main body of experience in this review comes from healthy women between 35 and 44. On the other hand, one should remember that these women have a high motivation to use contraceptive methods and therefore the continuation rate in the trials is high. This compensates for the relatively small number of acceptors by giving more women-years in follow-up. Continuation rate and the proper use of methods are directly correlated to increase in age, socioeconomical status, and to education of users. Highly educated women in this age group have very low failure rate with almost any method.

Views of Cameroonian sex workers on a woman-controlled method of contraception and disease protection.

Five hundred and twenty female Cameroonian sex workers participating in a clinical trial of the effectiveness of nonoxynol-9 (N-9) contraceptive film to prevent HIV infection were interviewed to determine their experience with this woman-controlled method. The sex workers liked the film, with over 80% stating they would continue to use it if it were shown to be effective against HIV and were to become widely available. However, they were much more likely to use condoms and films simultaneously with their clients (40%) than with their regular partners (16%). The advantages ascribed to the film were that its use was under the woman's control; it could be used without the partner's knowledge; it allowed direct contact between partners; and it provided back-up protection in case of condom breakage. Data from this small study suggest that development of an effective, woman-controlled method of pregnancy and disease protection would be welcomed by these women.

[Intrauterine contraceptive devices (IUD'S) (author's transl)].

The IUD is an excellent and very effective contraceptive method. As contraception and coitus are separated, this technique is acceptable to many couples. It provides prolonged protection and cannot be "forgotten" like the Pill, the diaphragm, or the condom. Its pregnancy rate is 2 per 100 women per year. The greatest clinical experience exists with the Lippes loop. The loop should be the method of choice for parous women, the Copper-T for the nullipara and nulligravida. Regularly menstruating women should be advised to use additional contraceptive protection (condom, diaphragm, coitus interruptus, foam) during the week of highest fertility. This will make the IUD as effective as the Pill. Physicians prescribing this method should be available 24 hours per day for their patients, as emergency situations such as P.I.D., ectopic pregnancy, septic abortion--rare as they are--would need prompt attention.

HIV infection in women: impact on contraception.

A study was performed to evaluate the impact of knowledge of HIV infection (diagnosis) on contraception information and choices for HIV infected women. A questionnaire was given to 140 HIV infected women. Most of the studied population included young women with a low educational level. A significant increase in the knowledge of contraceptive methods was observed after diagnosis of being HIV infected. The data suggested that the women who received information had never received it before, or that the diagnosis created a stronger motivation to listen to the counseling offered. A significant increase in the use of contraceptive methods was also found, especially male condoms and tubal ligation. Total number of children had a strong impact on contraceptive method at the time of interview. Only 5 of 23 HIV infected women who had no children used hormonal contraceptives, while 15 of 23 preferred condom use, and 3 of 23 chose not to use any contraceptive method. Tubal ligation was performed in approximately 9% of the women who had only one child. However, 12.4% of the sexually active HIV infected women were still not using any contraceptive method at the time of the interview. A combined method (male condom plus another contraceptive) was used by only 27% of sexually active HIV infected women, despite health service counseling. In conclusion, the realization of being HIV infected had a strong impact on contraceptive practice among these women. It is expected that HIV and family planning clinics will address HIV infected women's needs and be prepared to integrate contraception and gynecological care.

Sexual activity and contraceptive use among female adolescents--a report from Port Harcourt, Nigeria.

Seven hundred and sixty-eight randomly selected single senior secondary school girls from Port Harcourt (mean age 16.32 years) were surveyed on aspects of sexual activity and contraceptive use. Two hundred and ten pregnancies (24 deliveries and 186 induced abortions) had occurred in 142 out of 605 girls (78.8%) who admitted being sexually exposed. The mean, modal and youngest ages of initiation into sexual activity were 15.04, 15 and 12 years respectively. At the time of the survey, 190 girls (24.7%) were sexually active and 74.2% of their male consorts were older working men, suggesting financial gains as a motive for the girls' sexual activity. Other findings were high awareness (72.4%) of the relationship between sexual activity and sexually transmitted diseases; a rather low level (56%) of knowledge of effective contraceptive methods, and limitation of contraceptive method use by sexually active girls, largely to the rhythm and withdrawal methods. Exposure to multiple sexual partners and a high level of parental approval of subjects' use of contraception were also present. In view of our findings, it is suggested that active efforts to promote sexuality education and contraceptive use should be intensified among Nigerian adolescents.

[Sexual behavior and contraceptive practices among university students].

The aim of this work was to study the knowledge, opinions and sexual behaviour of a sample of 464 students from the Universidad Austral de Chile. Results show that 78% of male and 41% of female students have had a sexual intercourse and that 78% of males and 72% of females with an active sexual life use contraceptive methods. The principal reasons to avoid the use of these methods are the irregularity of sexual intercourse and the reduction in pleasure. Most students think that these methods are harmful for their health but they should be used. The use of contraceptive methods increase with the frequency of sexual relations and university experience, but first year students use them more frequently than second year students. Most students know several contraceptive methods, but their knowledge about mechanisms of action is inadequate or distorted. Likewise, more than 50% think that it is possible to prevent pregnancy after a sexual intercourse. It is concluded that most sexually active students use contraceptive methods, but inappropriately. Stereotypes, myths and lack of information are influencing their sexual and contraceptive practices, showing incoherence between their knowledge and behavior. A possible explanation could be a scarce influence of high school and religion on their sexual formation.

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.

Reproductive mortality.

The transfer from traditional to modern methods of contraception in recent decades has been accompanied by a transfer of deaths from complications of pregnancy to deaths from complications of the modern contraceptive methods. In 1975, for example, it is estimated that there were more deaths at ages 25-44 years in England and Wales from adverse effects of oral contraceptive use than from all complications of pregnancy, delivery, and the puerperium combined. Thus maternal mortality is no longer an adequate indicator of the deaths associated with reproduction in the community. An alternative measure, the reproductive mortality rate should be used, which includes deaths from complications of contraceptive use as well as those from complications of pregnancy or abortion. The reproductive mortality rate in England and Wales seems to have declined continuously since 1950 for women aged 25-34. But after 1960 it increased for women aged 35-44, because of the higher mortality associated with oral contraceptive use in this age group.

The value of transvaginal ultrasound to monitor the position of an intrauterine device after insertion. A technology assessment study.

BACKGROUND: The intrauterine device (IUD) is an effective contraceptive method. The contraceptive power as well as the side-effects of IUD are thought to relate to the position of the IUD in the uterine cavity. We assessed the accuracy of clinical evaluation of IUD position. METHODS: A prospective comparative study was performed. The clinical evaluation was compared with the TVU measurement of IUD position both immediately after insertion and 6 weeks after insertion. The primary outcome measures were the positive and negative predictive values (PPV and NPV) of the clinical evaluation of IUD position. RESULTS: 195 women were included consecutively, 181 women (92.8%) were available for follow-up. The PPV and NPV of clinical evaluation of IUD position immediately after insertion were respectively 0.60 (95% CI: 0.39-0.81) and 0.98 (95% CI: 0.96-1.0). The prevalence of an abnormally positioned IUD was 7.7% (95% CI: 3.9-11.4). The PPV and NPV of the clinical evaluation at follow-up were respectively 0.54 (95% CI: 0.26-0.81) and 1.0 (95% CI: 0.98-1.0). The prevalence of abnormal position was 4.0% (95% CI: 1.7-7.1). CONCLUSION: Clinical evaluation is an excellent test for the evaluation of the position of an IUD and routine TVU is not indicated for this purpose.

Vaginal bleeding patterns among women using one natural and eight hormonal methods of contraception.

Menstrual diary records were obtained from a total of 5257 women using nine different methods of contraception, one natural and eight hormonal. This paper presents a comparative analysis of their vaginal bleeding patterns. The analytic procedures follow the recommendations of a recent WHO workshop on bleeding pattern analysis, which involve dividing each subject's diary into successive 90-day reference periods, calculating ten indices for each period, and classifying women according to whether they have "clinically important" bleeding disturbances. In general, the findings of this analysis confirm those of previous studies. Women using the natural method, who were deliberately selected for the regularity of their menstrual cycles, averaged three bleeding/spotting episodes of length 5 days in each 90-day period, with very little variability within or between women. Subjects given a combined oral contraceptive had more regular patterns than any other treated group, with short (4-day) episodes and 23-24 day bleeding-free intervals. Progestogen-only pill users had more frequent, longer episodes and shorter, less predictable intervals than combined pill users. Contrary to widely-held beliefs, the progestogen-only pills produced fewer spotting days than the combined pills, and almost no spotting episodes at all. Nearly half of vaginal ring users experienced some menstrual disturbance in each period; their most common problems were irregular, infrequent or prolonged bleeding. Women using the long-acting injectable, depot medroxyprogesterone acetate, had totally unpredictable patterns, with infrequent but prolonged bleeding/spotting episodes. The incidence of amenorrhea rose from just under 10% in their first injection interval to over 40% in their fourth. The methods of analysis recommended by WHO in 1985 still require substantial refinement. Nevertheless, they are more sensitive than those used previously for WHO trials and produce an easily understood, clinically meaningful characterization of bleeding patterns.

[Risk factors of pregnancy in teenagers using family planning. Work Group on Sexuality and Adolescence].

BACKGROUND: Pregnancy and maternity during adolescence constitutes an obstetric and perinatal risk factor and reason for increased social alarm. Nonetheless, the predisposing factors have been little studied in Spain. METHODS: The demographic data and information on the age of onset of sexual relations, contraceptive methods used, in addition to the reason for the first visit, corresponding to the users of six municipal family planning centers in Barcelona who were under the age of 20 years at the time of the first visit were analyzed. Likewise, the principal incidences in the follow up, including pregnancies, abortions and changes in contraceptive methods were collected. RESULTS: From October 1989 to September 1990 823 first visits corresponding to adolescents were registered. Forty-five percent (380) were under the age of 18 years with 716 (87%) having initiated full sexual relations with more than two years having passed prior to the first visit to the center in 183 cases (26%). The most frequent reason for the visit to the center was to request contraception (48%). The lack of labor and academic activity, in addition to the infrequent use of condoms were associated to pregnancy as the reason for the consultation in 42 cases. Twenty-four adolescents became pregnant during follow up being associated to the early initiation of sexual relations, with an interval of two or more years prior to attending the center and a change in contraceptive method. CONCLUSIONS: The delay in attending family planning centers and the use of little effective contraceptive methods are risk factors for undesired pregnancy in adolescence.

Factors affecting the consistent use of barrier methods of contraception.

OBJECTIVES: To discuss the major issues involved in the consistent and effective use of barrier methods of contraception. DATA SOURCES: Major research and review articles on barrier methods published within the last 10 years were considered. One major source of articles was Family Planning Perspectives. METHODS OF STUDY SELECTION: This paper is a focused review and integration of recent literature rather than a comprehensive literature review. Only selected articles published since 1986 that are pertinent to the issues raised are included. TABULATION, INTEGRATION, AND RESULTS: All barrier methods have common characteristics that influence their patterns of use. The correct and consistent use of such methods is determined by the complex interaction of characteristics of the methods themselves, characteristics of users, and the situational context. Method characteristics include the extent of interference with sexual spontaneity and enjoyment, the amount of partner cooperation required, and the ability of the method to protect against human immunodeficiency virus and other sexually transmitted diseases. User characteristics include motivation to avoid unintended pregnancy, ability to plan, comfort with sexuality, and previous contraceptive use. Stage of sexual career, relationship characteristics, and physical and sexual abuse are important situational influences. CONCLUSIONS: Even though most barrier methods can be obtained without a prescription from a provider, clinicians have an extremely important role in promoting effective and consistent method use. Four major ways to improve the use of barrier methods currently available include: 1) improve method characteristics and the distribution systems; 2) change consumers' perceptions of method attributes; 3) train consumers to use methods correctly and overcome-perceived negative characteristics of the methods; and 4) change values about the perceived importance of method characteristics. There also is an urgent need for the development of better barrier methods.

New antifertility agents active in the rabbit vaginal contraception (RVC) method.

Zinc salts in aqueous K-Y Jelly are effective vaginal contraceptives in the rabbit. The minimum effective dose is 54 to 60 mg Zn/ rabbit as acetate, gluconate or lactate. Zinc salts added to suboptimal doses of Ortho-Gynol Jelly or Delfen Cream improves the vaginal contraceptive efficacy of these products. Twenty-seven mg zinc/rabbit as lactate or acetate and 28 mg zinc/rabbit as sulfate or chloride in 0.1 to 0.5 ml of cream or jelly are effective. Gossypol is effective at a dose of 2 mg/rabbit. Although there is some rationale for their use, manganese has no antifertility effect and valium appears to promote fertility. The rabbit vaginal contraception (RVC) method shows undesirable variation but use of sufficient animals yields logical and reliable results. Artificial insemination instead of breeding appears to decrease variation.

Are there adverse effects of periconceptional spermicide use?

Recent studies have suggested that spermicide exposure around conception may cause congenital malformations, reduced birth weight, or spontaneous abortion. This large, prospective study examined the risk for multiple malformation, patterns of malformations, low birth weight, preterm delivery, and spontaneous abortion in infants whose mothers used spermicides only before or after their last menstrual period, compared with a control group using other contraceptive methods. The multiple malformation rates in women using spermicides only before or after their last menstrual period were 3.8 and 4.8 per thousand, respectively. For the control groups, the corresponding rates were 5.4 and 6.4 (not significant). No pattern of malformations was found in spermicide-exposed infants. The risk of preterm delivery, the risk for producing a low-birth-weight (less than 2500 gm) infant, and the risk of spontaneous abortion were no higher in women exposed to spermicides than in women using other methods of contraception. This study finds no evidence that spermicide exposure around the time of conception is dangerous to the fetus.

Apparent oral contraceptive failure associated with antibiotic administration.

The concomitant use of antibiotics and oral contraceptives should be included in the assessment of contraceptive failure. A case of unwanted adolescent pregnancy during the use of a semisynthetic penicillin and an oral contraceptive is presented and discussed. Advising a different contraceptive method or an additional contraceptive modality may be indicated in adolescents taking long-term antibiotic medication.

Contraceptive decision making among Medicaid-eligible women.

The purpose of this study was to examine the influence of sociodemographic factors, attitudes, knowledge, and experiences regarding the use of various contraceptive methods, future plans prenatally, and actual use postpartum among a population of low income pregnant women. Women were interviewed prenatally and during the postpartum period in a large, urban academic health center serving primarily an indigent population. The primary analytic method employed was logistic regression. The key finding in this study is that women are not consistently using the method of contraception postpartum that they planned during the prenatal period. Only 54.7% of the women planning to use oral contraceptive pills were using them postpartum, and only 31.3% of the women planning to use condoms were actually using them postpartum. Expanding contraceptive education and counseling throughout the perinatal period may assist women's decision making.
