Humans have tried to control fertility for centuries. Primitive, preliterate societies practiced infanticide and abortion. When primitive women understood the advantages of conception control, they tried, when possible, to use contraception. In the 4th century B.C., Plato and Aristotle advocated a one-child family. Greek medical literature reported a hollow tube inserted through the cervix into the uterus and a potion as contraceptives. Islamic physicians had much knowledge about conception control. The attitudes toward contraception. In the 5th century B.C., Saint Augustine condemned contraception, even among married couples. The condom emerged in the early modern period. Yet, they were usually worn to protect against disease, e.g., bilharzia in Egypt and syphilis in Europe. The cervical cap and the diaphragm are examples of occlusive pessaries. By 1880, contraceptives and spermicides were advertised. In 1928, the IUD joined the existing contraceptives. Today we have combined oral contraceptives. Judaic law requires husbands to fulfill their wives sexual needs, separate from their duty to procreate. It also calls men, not women, to procreate and forbids men from masturbating, thus Judaic law does not forbid women from practicing contraception. The Roman Catholic church forbids contraceptive use because it is a sin against nature. Some Protestant denominations have allowed contraceptive use. Islamic law states that children are gifts from Allah. Some Moslems believe that they must have many children, but Allah and the Prophet state that children have rights to education and future security. These rights allow couples to prevent pregnancy. Neither Hinduism nor Buddhism prohibit contraceptive use. Differences in husband-wife communication, sex roles, access to contraceptives, and traditional family values will have more of an effect on contraceptive use and fertility than theological barriers or the social class of religious groups. 相似文献

The prevalence of unmet need for family planning is a primary justification for family planning programs, but the causes of unmet need have not been much explored. This article investigates four explanations for unmet need: (1) as an artifact of inaccurate measurement of fertility preferences and contraceptive practice; (2) as a reflection of weakly held fertility preferences; (3) as a result of women's perceiving themselves to be at low risk of conceiving; (4) as due to excessive costs of contraception. The explanations are examined using quantitative and qualitative data collected in 1993 from currently married women and their husbands in two provinces in the Philippines. The results indicate that the preference-behavior discrepancy commonly termed "unmet need" is not an artifact of survey measurement. The most important factors accounting for this discrepancy are the strength of women's reproductive preferences, husbands' fertility preferences, and the perceived detrimental side effects of contraception. Inaccessible family planning services appear to carry little weight in this setting. Modification of services to make them more attentive to other obstacles to contraceptive use would improve their effectiveness in reducing unmet need. 相似文献

While both physicians and patients are concerned about the possible risks of using oral contraceptives, the Royal Society's Study Group on Risk has shown that the fear experienced when confronted with various potential causes of personal harm is not influenced just by individual estimates of the likelihood that harm may occur, nor by its severity if it does. Other factors are involved. Moreover, with regard to contraception, the involvement of sexuality affects risk perception and decision making. General practitioners should help their patients realistically evaluate the risks of oral contraceptive use. The likelihood that good results will emerge from a consultation depends upon the application of an individualized, couple-based approach with caution, common sense, and attention to psychological issues. Doctors need to consider and explain both the risks and benefits of using oral contraception. The benefits of combined oral contraceptives (COCs) and progesterone-only contraceptive pills (POCPs), the contraceptive consultation, the doctor's concerns about risk, minimizing COC risks, the relative risk of death as a result of using oral contraception, minimizing POCP risks, and perspectives on the risks of oral contraception are discussed. 相似文献

This study evaluated the sexual knowledge (including contraceptive and reproductive knowledge), contraceptive use, and self-esteem among a sample of 158 male and female United States Navy sailors assigned to Navy ships. In spite of the fact that men and women viewed themselves as relatively knowledgeable with respect to contraception, results showed substantial knowledge deficits. Women demonstrated significantly greater sexual knowledge than men, and contraceptive/ reproductive knowledge was highly correlated with self-reported use of contraceptives. Finally, self-esteem was highly correlated with sexual knowledge and certain contraceptive use behaviors. 相似文献

Genitourinary medicine (GUM) clinics are likely to play an expanded role in the provision of family planning services. A recent survey of GUM clinics in the UK indicated that 71.4% provided emergency contraception and 48.1% provided routine contraception services. To facilitate the ability of GUM practitioners to provide contraceptive counseling and supplies to both men and women, this article reviews the current state of emergency contraception, combined oral contraceptives (OCs), modern IUDs, the levonorgestrel-releasing intrauterine system, female condoms, and the personalized computerized contraceptive system Persona. Also reviewed are current issues regarding the possible impact of combined OCs on an increased risk of venous thromboembolism and breast cancer. 相似文献

This essay examines Haitian cultural and programmatic barriers to modern contraception and reports on types of unions as they relate to pregnancy and the prevalence of contraception. Findings from three mini-surveys representing 2383 rural and urban women in unions show that the most popular unions are maryé and plasé (legal marriage and setting up an household). Among rural women living in unstable relationships, vivav'ek, remen and menaj (living with someone, lovers, living as a pair), about 18% reported being pregnant at the time of the surveys. Findings also reveal that more urban women use contraceptive methods (23%) than do rural women (13%). However, the choice of contraceptive method appears to be influenced by medical staff and the availability of methods. Discussion examines the results of the surveys, women's position within the culture and attitudes toward the use of modern contraception. It also gives suggestions for improving family planning services by reinforcing the training of providers and supplementing their work with a team of volunteers who would encourage and support first-time users and dissatisfied users with meetings and home visits. It is also suggested that the promotion of informal education and the teaching of practical skills in mothers' clubs would encourage women to become economically independent from their partners so they would not focus on reproduction as a means to tie a man to them for emotional and economic purposes. 相似文献

This report analyzes various aspects of contraception in Spain. One notable finding is the wide socioeconomic, cultural and health variation among regions. Since 1975 a significant drop in the birth rate has been observed overall. Twenty per cent of the women studied at risk of pregnancy are using oral contraceptives. The most widespread contraceptive method is still coitus interruptus, followed by oral contraception and the condom, as well as the rhythm method. The highest use of oral contraceptive and IUDs is seen in Catalonia (20% and 26% respectively) followed by Andalusia, Madrid and Valencia. Although contraception has only recently become legal in Spain, it is widely available either without charge or very inexpensively; all methods including abortion are available. At present, priority is given to special interest groups such as women in special circumstances, teenagers, etc. and to special programs like "Integrated Care for Women" which includes contraception, STD, pregnancy monitoring, early diagnosis of gynaecologic cancer and menopause. 相似文献

In this paper we examine the effects of socioeconomic development, the status of women, and family planning on fertility and the extent to which these effects vary among the nineteen districts of Bangladesh. The 1983 and 1991 Bangladesh Contraceptive Prevalence Survey data are used to examine the effects of these factors on differences in contraceptive use among currently married women aged 15-49. The proportion of currently married women aged 15-49 using contraception was 46.3 per cent in 1991, a considerable increase from 26.5 per cent in 1983. Contraceptive use rates for all the districts increased substantially over the period between 1983 and 1991 and the gap between Dhaka's rate and those of other districts was narrower in 1991 than in 1983. An analytical model composed of socioeconomic development, status of women, and family planning variables is tested using logistic regression. The logit model is used to evaluate the effects of a selected group of variables on the probability of using contraceptive methods. The analysis demonstrates clearly that socioeconomic development and women's status significantly impact the use of contraceptive methods in Bangladesh. The results also suggest that better-educated, employed women are more likely to use contraception than those who have little or no formal education and who are not employed. In 1983, rural-urban differences in contraceptive use were significant, but in 1991 area of residence was not significant, which suggests that family planning programs may have played an important role in providing contraceptive information and technology to rural areas. Our analysis also suggests that family planning programs operated more efficiently in some districts than in others, and regional differences remained important in 1991 as they were in 1983. Decomposition analysis suggests that shifts in population structure favored increased contraceptive use in Bangladesh. This analysis also indicates that change in rate is also important, contributing about 21 per cent of the overall increase in contraceptive use. 相似文献

In the last decade, global use of contraceptive methods has increased. About 50% of couples of childbearing age use a modern contraceptive method. This evolution and a positive change in attitude towards male contraception has encouraged research in fertility regulation to enlarge and to improve acceptance of the contraceptive mix. Current injectable contraceptives interfere with the menstrual cycle. Research is exploring ways to minimize such secondary effects by reducing the total hormone dose and by changing the way the active product is delivered (e.g., microspheres). An injectable prototype is an analogue of levonorgestrel (HRP 002). A new IUD is made of leather suspended by a nylon suture which has been inserted into the uterine muscle. RU-486, often used to interrupt early pregnancy, is being tested as an oral contraceptive (OC). It inhibits secretion of gonadotropins and ovulation. It holds promise as an OC with no estrogen component. Since it also inhibits endometrial development and thus prevents implantation, it may someday be used for emergency contraception (i.e., postcoital contraception). New contraceptive implants under study include Norplant RII (2 rods of levonorgestrel lasting for 3 years), Implanon (desogestrel), and Capranor (biodegradable implant lasting 2 years). The female condom consists of a flexible polyurethane sheath with a flexible ring at each end. It has the potential to protect against sexually transmitted diseases since it covers the labial lips and is impermeable to HIV. France and Switzerland have both approved its use. It will enter the UK market at the end of the year. Approval for marketing has been sought in the US. 相似文献

Reproductive changes in sub-Saharan Africa are contingent upon women's socioeconomic conditions and informational and cultural resources. This study focuses on socioeconomic and cultural determinants and correlates of the intention to stop childbearing and of contraceptive use among urban women in Mozambique. It uses data from a survey of 1,585 married women conducted in Greater Maputo in 1993, and it employs logistic regression for multivariate analysis. The results of the analysis indicate that although the stopping intention and contraceptive use are interrelated and similarly affected by such factors as education or the area of residence, the intention to stop childbearing is mainly driven by women's perception of their material conditions and socioeconomic security, while contraceptive use is largely a product of social diffusion and the legitimization of innovative, Western-origin information and technologies. The study proposes that these findings may help explain the unique features of the fertility transition in sub-Saharan Africa. 相似文献

BACKGROUND: Oral contraceptives are prescribed as contraception but also as therapy for menstrual cycle disturbances and acne. We studied the prevalence of oral contraceptive (OC) use and the indications to start OC use among adolescents. METHODS: A cohort consisting of ninth grade secondary school girls (mean age 15.3+/-0.6 (s.d.) years) answered a questionnaire on their menstrual cycle. OC users were asked about duration and reasons for OC-use and the name of the preparation they used. The influence of calendar age, gynecological age and level of education on the prevalence of OC was studied by multiple logistic regression analysis. RESULTS: The response on the questionnaire was 92%. Of 2248 responders 248 (11%) used oral contraceptives: 74% used low dose 'sub 50' preparations, 3% pills with 50 microg estrogen, 3% tri-phase preparations and 17% pills with antiandrogens. Of girls aged 14, 15 and 16 years 4%, 12% and 28% respectively, used OC. Of the 15-year-olds 31% mentioned contraception as most important reason for OC use, 18% menstrual cycle irregularity, 26% dysmenorrhea, 10% acne and 5% other reasons. Calendar age, gynecological age and level of education were independent variables for OC use in general and for OC use for contraception or dysmenorrhea, but less so for OC use for menstrual cycle irregularity or acne. CONCLUSIONS: During adolescence low dose OC's were frequently used. In The Netherlands OC use among girls aged 15 and 16 years doubled in comparison with 1982. One third of the adolescent OC-users mentioned contraception as most important reason to start OC. Gynecological age (a determinant of biological maturation), calendar age (a determinant of biological maturation and lifestyle in peer groups), and level of education (a determinant of lifestyle in peer groups) were associated with OC use. 相似文献

In this study, the previous history of family planning and prior usage of contraceptive methods are analyzed, in a sample of 175 women who voluntarily opted for surgical sterilization as a permanent method of fertility regulation, in the Panamanian Social Security System. A questionnaire was applied during the second trimester of pregnancy, by which information would be gathered in regard to knowledge, usage and adverse effects of the contraceptive methods used prior to the intervention. Results showed that 99% of the sample had heard, on some occasion about oral contraceptives (OC) and, in lesser proportion to intrauterine devices (IUD), barrier methods and hormonal inyectables. The first contraceptive method used, and the one of longest usage, was the combined OC, of which 43% begun between 17 and 25 years of age. In contrast, 7.4% initiated contraception with IUD, from the age of 26 years. The health personnel constituted the major source of recommendation for contraceptive usage and, despite the fact that 37% of the sample did not use contraception prior to the last pregnancy, over half of the subjects responded that combined OC were considered as the most secure method. 相似文献

OBJECTIVE: Oral contraceptives (OC) are the most efficient method of contraception and it is the most prescribed by doctors in developing countries. Therefore we studied the effects of combination pill and mini-pill on calcium and phosphorus in milk of breast-feeding mothers at different stages of lactation. METHODS: Fifty-four breast-feeding mothers made up three study groups: 33 mothers who had been advised by their doctors to use either combination pill (12), or mini-pill (21), as well as a control group of 21 mothers that used no hormonal contraceptives. All mothers completed a questionnaire and provided samples of milk before and after a measured period of observation. Mean duration of study was 76, 120, and 101 days, respectively for users of mini-pill, combination pill, and controls. Determination of calcium and phosphorus was done by inductively coupled plasma-atomic absorption spectrometry. RESULTS: Overall the decrease in milk concentrations of phosphorus (6%) and calcium (26.3%) during the study period was not influenced by OC treatment. Regression analyses which took into consideration length of treatment, socioeconomic status, number of children, duration of previous lactation, type of contraceptive, and age of mothers and repeated measurements (before and after OC) showed that milk calcium was significantly affected by stage of lactation (p=0.0013). CONCLUSION: The use of hormonal contraceptive such as the combination pill (levonorgestrel 0.15 mg+ethynilestradiol 0.03 mg) and mini-pill (norethindone 0.35 mg) does not seem to affect the secretion of calcium and phosphorus in milk of mothers. 相似文献

The choice of a good contraception is difficult in allograft recipient woman. Even if patients recovered a normal menstruation and fertility, the oral and the intra-uterine devices contraceptives are contraindicated. If pregnancy occur too soon after the transplantation, the survival graft is in danger. According to the literature, 50% allograft recipient have begun a pregnancy without medical concentration. In this article, we wanted to find the contraceptive method effective and appropriate in recent allograft recipient female according to the organ grafted. We discuss the new contraceptive methods and advise to avoid, in first instance a tubal ligature. 相似文献

Levonorgestrel 6-capsule subdermal implants (Norplant) are an effective form of reversible contraception. When implanted under the skin of the upper arm, they release drug into the circulation at a relatively constant rate over 5 years. Generally, the cumulative pregnancy rate at the end of 5 years' levonorgestrel implant use is less than 2 per 100 users. The implants provide contraceptive efficacy equivalent to, or better than, that provided by other reversible methods (including oral contraceptives). Younger women are more likely than older women to become pregnant while using levonorgestrel implants. Bodyweight was positively correlated with risk of pregnancy in a number of studies, but may not be a factor with the currently available 6-capsule implant formulation. Limited data suggest that a new 2-rod levonorgestrel subdermal system (Jadelle) is as effective as the more extensively studied 6-capsule system and has a similar tolerability profile. Fertility returns rapidly after the implants are removed. Use of levonorgestrel subdermal implants is compatible with breast-feeding. In several studies, discontinuation rates were 2 to 15% during the first year of use; cumulative 5-year discontinuation rates ranged from 22 to 64 per 100 women. Despite a substantial incidence of adverse events during therapy, levels of user satisfaction are generally high. Menstrual abnormalities (increased or decreased menstrual flow, spotting, irregularity and amenorrhoea) affect most women at some time during therapy and are the most frequent reason for discontinuing levonorgestrel implants before the end of 5 years' treatment (incidence of 4.2 to 30.7 per 100 users). Mood changes and headache also may lead to discontinuation. Other reported adverse events include skin reactions (including acne), dizziness and weight gain. Serious adverse events (such as stroke, thrombotic thrombocytopenia and idiopathic intracranial hypertension) have been reported during levonorgestrel implants therapy, but the population incidence is difficult to calculate and causality is unclear. According to 3 pharmacoeconomic analyses from an institutional or managedcare perspective, all contraceptive interventions result in net cost savings. It is not clear whether levonorgestrel implants provide greater or smaller economic benefits than combined oral contraceptives. CONCLUSION: Levonorgestrel subdermal implants provide effective long term contraception. Despite a high incidence of menstrual adverse events, overall levels of user satisfaction are high, and 1-year continuation rates are better than those for combined oral contraceptives. Levonorgestrel subdermal implants are a good choice of contraceptive method in women who desire effective contraception, but who are unable to, or prefer not to, comply with an oral regimen. 相似文献

OBJECTIVES: The study was planned to determine current trends in contraceptive usage and to examine the attitudes, needs and preferences of women with respect to oral contraceptives. METHODS: Semi-structured interviews were carried out with women (n = 1201, aged 16-45 years) in Germany, the UK and France. RESULTS: The study revealed that oral contraceptives were the most popular method of contraception employed, followed by condoms, and that the majority of respondents were aged 16-19 years when they first used an oral contraceptive. An important finding of the study was that an oral contraceptive was first used only after having sexual intercourse for the first time (within 1 year), emphasizing the importance of effective contraceptive information and education for adolescents. Regarding non-contraceptive health benefits, protection from ovarian and endometrial cancer was perceived by respondents to be of the greatest importance; however, few women were spontaneously aware of this benefit. When given a number of different oral contraceptive intake options to assess, the established 'once daily for 21 consecutive days' option remained the most popular, although a 'once weekly' alternative was cited by many women. When asked about the preferred frequency of menstrual bleeding, there was a polarization between women favoring the normal monthly bleed and those wanting a 'no-bleed' regimen. CONCLUSION: Women are poorly informed about oral contraceptive use, and are largely unaware of the important long-term non-contraceptive benefits. Many women would prefer alternative pill intake options and a significant number would favor a 'no-bleed' regimen. 相似文献

The fertility decline in Hong Kong appears to be the result of 1) the economic and social development achieved during the 1960s which created an environment favorable to the development of a family planning program, and 2) the changes in the practice of and to a lesser extent the attitude toward contraception induced by the Family Planning Association (FPA). The FPA has motivated people to accept family planning services and has provided them with an inexpensive and convenient source of contraceptives. Prior to 1966, posters, pamphlets, and newspaper advertisements were the main sources of publicity with radio and television used only on a limited basis. Since 1966 the existing channels of communication have been modified and new approaches in the form of film showings, contests, and telephone inquiry services have been developed to inform and motivate couples to begin contraceptive practice. After many years of these publicity campaigns, over 95% of all married women in Hong Kong understand that contraceptives can be used for limiting births and practically all of them are familiar with the FPA. Additionally, the most important referral source, accounting for over 85% of all new acceptors, has been the person-to-person contact made by the FPA family planning workers as well as satisfied clients. In 1966 fieldwork operations were expanded and a new recruitment strategy was initiated in which activities were increasingly concentrated in maternal and child health centers. The effect of reaching young and low parity women in the mid- to late 1960s has been cumulative. Since 1969 there have been indications that fertility decline is increasing in the older age groups. Although the extent to which the FPA's activities encouraging the use of the more modern methods of contraception affected the fertility decline is difficult to determine, it is obvious that the population was receptive to the new and improved methods as evidenced by the boom of acceptors in 1965 when IUD insertions were at their peak and by the 2nd boom in 1969 when the large-scale distribution of orgal contraceptives began. 相似文献
