Rural and urban Midwestern United States contraception practices.

To address a paucity of demographic data on rural United States contraception practices, 370 randomly selected menstruating women, age 13-55 years, living in rural and urban Illinois and Missouri answered interview questions. Women with relatively few children and living in urban areas were likely to practice contraception more than those with relatively few children and living in rural areas, p < 0.01. In Illinois, more rural (23%) than urban (2%) women chose sterilization, p < 0.01. Single status was more frequent in Chicago (41%) and rural Missouri (32%) than in rural Illinois (19%), p < 0.002, and extant research links single status with risk for HIV and other sexually transmitted diseases (STDs). Condom use did not differ significantly by locale, p > 0.05. Urban-rural differences in contraception practices may be a function of life style choices (e.g. urban women may practice contraception to postpone having children, whereas rural women may practice contraception to prevent having more children after families are complete). Results do not strongly support that locale differences in contraception practices are a function of concern about contracting STDs.

Factors affecting the contraceptive choice in a developing country.

OBJECTIVES: To evaluate the factors affecting the contraceptive choice of women in a developing country. METHODS: Demographic characteristics, education and income level, previous and current contraceptive choices of the women from a maternity and a university hospital were retrospectively reviewed for 2 years. The data obtained from the two hospitals were analyzed by Student's t- and chi2-tests. RESULTS: Family planning services were offered to 651 and 7427 women in the university and the maternity hospital, respectively. Although the mean ages and income levels of the women in two centers were similar, the women in the university hospital had lower mean gravidity and mean number of living child, while they had higher education level and previous modern contraceptive use (P < 0.05-0.001). The women in the university hospital more frequently preferred combined oral contraceptive and surgical sterilization, while those in the maternity hospital chose condom and intrauterine device (P < 0.01-0.001). CONCLUSIONS: Women with higher education level had a lower number of pregnancies and living children due to more frequent use of previous effective contraception and they chose combined oral contraceptives and irreversible methods more frequently.

Adolescents' contraceptive use and pregnancy history: is there a pattern?

OBJECTIVE: To examine the association between pregnancy experience and adolescents' contraceptive use. METHODS: We conducted a retrospective study of 920 sexually active adolescents not desiring pregnancy. Adjusted multivariable logistic regression analyses were used to assess the explanatory value of previous birth and abortion as well as first pregnancy at presentation on contraceptive practice. RESULTS: Twenty-seven percent of the adolescents had been pregnant. Regardless of pregnancy history, 52% of adolescents used noneffective contraception (ie, condoms inconsistently or no method). Adolescents with previous abortion were three times (odds ratio [OR] 3.4, 95% confidence interval [CI] 1.6, 7.3) more likely than never-pregnant adolescents to use hormonal contraception. However, although more likely to use contraceptive injections or implants, adolescent mothers were not more likely than never-pregnant adolescents to use oral contraceptives. Adolescents with prior abortion or birth were less than half (ORs 0.3 and 0.4, 95% CIs 0.2, 0.5 and 0.2, 0.6, respectively) as likely as never-pregnant adolescents to use condoms consistently. CONCLUSION: Previous pregnancy is associated with increased likelihood to use hormonal methods; however, a significant proportion of adolescents use noneffective methods and, thus, are at risk for repeat teenage pregnancies.

Contraceptive use among adolescent mothers at 6 months postpartum.

OBJECTIVE: To assess patterns and predictors of reliable and unreliable contraceptive use among adolescent mothers in the first 6 months following delivery. METHODS: We surveyed 462 women, 18 years of age or younger, at delivery and again at 6 months postpartum. Contraceptive behaviors were evaluated among the 359 adolescents who stated they were sexually active and not trying to conceive. RESULTS: Method discontinuation and switching were common during the 6-month interval. Only 100 of 189 adolescents (53%) initially prescribed oral contraceptives were still using this method 6 months after delivery; ten of these 100 stated that they had missed at least three pills in the last cycle. Twelve (10%) of the 115 adolescents who initiated depot-medroxyprogesterone acetate failed to obtain a second injection within 4 months of the initial injection or use an alternative method. In contrast nine of the ten women who received levonorgestrel implants were still using this method 6 months after delivery. Overall, 76% of the sample reported using reliable contraception at last intercourse. Multivariate analyses identified seven factors as predictive of reliable contraceptive use: school enrollment, not having failed a grade in school, adequate support, belief that pregnancy is likely without birth control, attendance at postpartum visit, prior abortion, and the adolescent's desire to wait at least 2 years before having another child. CONCLUSION: Interventions designed to reduce rapid repeat pregnancy during the adolescent years should address emotional, financial, and educational, as well as contraceptive, needs.

Access to emergency contraception.

OBJECTIVE: To evaluate access to emergency contraception among women seeking help from clinicians who registered to be listed on the Emergency Contraception Hotline (1-888-NOT-2-LATE, ie, 1-888-668-2528) and the Emergency Contraception Website (not-2-late.com). METHODS: Two college-educated investigators posing as women who had a condom break the previous night called 200 providers to seek help. RESULTS: Only 76% of attempts resulted in an appointment or telephone prescription from a hotline provider within 72 hours, 14% were failures, and 11% resulted in referrals to other providers not listed on the hotline or website. CONCLUSION: Even under ideal conditions, access to emergency contraception is currently constrained. Although emergency contraception could reduce significantly the incidence of unintended pregnancy and the consequent need for abortion, its potential will not be realized unless women have better access to clinicians who can prescribe emergency contraceptive pills.

Mortality in relation to oral contraceptive use and cigarette smoking.

BACKGROUND: As part of the Oxford Family Planning Association study, we compared mortality in relation to oral contraceptive use and smoking to highlight the differences between them from the perspective of public health. METHODS: The study consisted of 17032 women, aged 25-39 years at entry, recruited between May 1, 1968, and July 31, 1974, who had used oral contraceptives, a diaphragm, or an intrauterine device. We assessed mortality from follow-up data recorded until Dec 31, 2000. The analysis is based on woman-years of observation. FINDINGS: We analysed 889 deaths. Women who had ever used oral contraceptives had increased mortality from cervical cancer (rate ratio 7.2, 95% CI 1.1-303), and decreased mortality from other uterine (0.2, 0.0-0.8) and ovarian cancers (0.4, 0.2-0.7). Oral contraceptives had some adverse effect on deaths from ischaemic heart disease in women who smoked 15 or more cigarettes per day. For all causes of mortality, the rate ratio for death in women who ever used oral contraceptives was 0.89 (95% CI 0.77-1.02). By contrast, this rate ratio was 1.24 (1.03-1.49) in those who smoked one to 14 cigarettes per day, and 2.14 (1.81-2.53) in those who smoked 15 or more cigarettes per day. INTERPRETATION: There was no harmful effect of oral contraceptive use on overall mortality. By contrast, death from all causes was more than twice as high in smokers of 15 or more cigarettes a day as in non-smokers. The harmful effect was already apparent in women aged 35-44 years.

[Adolescents and contraception. What should the pediatrician know? (Part 2)].

Many adolescents are sexually active and reproductive health is an important aspect of adolescent medicine. However, pediatricians are often uncomfortable with the issues of sexuality and contraception, for which they have not been particularly trained. The general purpose of this article is to increase pediatricians' sense of competence with adolescents, particularly when having to deal with or counsel on such a sensitive issue as contraception. This second of two parts addresses confidentiality and prescription of oral contraceptives to minors, how to ask questions about sexual and reproductive life, best initial choice and eventual subsequent switch of contraceptive pill, acne and oral contraception, problems with mental handicap, and finally, what about boys. Pediatricians interested in the care of adolescents are strongly invited to keep developing their expertise in the field of sexuality, contraception and reproductive health.

Young women's attitudes toward injectable and implantable contraceptives.

STUDY OBJECTIVE: To assess the potential acceptability of implantable and injectable contraceptive characteristics by young women of diverse ethnic and educational backgrounds. DESIGN: A cross-sectional self-administered survey. SETTINGS: The waiting room of three clinical sites: an elite women's college health service, a coeducational state university health service, and an inner city hospital-based adolescent clinic. PARTICIPANTS: 328 young women awaiting medical care in one of three clinical sites, aged 13 to 21 years (85% 18-21 years); ethnic distribution differed significantly by site. The majority (83%) were sexually active, and of those who were sexually experienced, 25% had been pregnant. OUTCOME MEASURES: A 47-item questionnaire examining attitudes toward characteristics of injectable and implantable contraceptive methods, menstrual, sexual, and gynecologic history. RESULTS: Sixty-two percent of the sample agreed that they would get an injectable method. There was little variation in agreement to get an injectable method by sexual or pregnancy history. Fewer subjects (24%) agreed that they would like to get subdermal implants and agreement to get an implantable method of contraception did not vary by sexual history; however, ever-pregnant young women (33%) were significantly more likely to agree to implants than never-pregnant subjects (21%; chi2, 4.109; p = 0.04). Seventy-four percent of subjects said they would stop using a contraceptive that caused irregular menses, whereas 65% would stop using a method that caused amenorrhea. CONCLUSIONS: An injectable contraceptive method has universal appeal across ethnic, educational, and age categories, whereas implants are less appealing. Irregular bleeding and amenorrhea are poorly perceived side effects of long-acting contraceptives.

The 2002 Canadian Contraception Study: Part 2.

The 2002 Canadian Contraception Study investigated the contraception and sexual health-related knowledge, attitudes, and practices of a representative sample of Canadian women of childbearing age. In Part 2 of the report of this research, the authors focus on the contraceptive attitudes and practices of adolescent women and women in their later reproductive years, provide data on sexual and reproductive health indicators of Canadian women, describe 2-decade trends in the awareness, opinion, and utilization of contraceptive methods among Canadian women, and describe contraception counselling strategies that may be used to improve patient choice and adherence to method. This report closes with an overall discussion of the findings of the 2002 Canadian Contraception Study.

Demographic and sociocultural factors influencing contraceptive use in Uganda.

Bivariate and multivariate analyses of the influence of demographic and sociocultural factors on contraceptive knowledge, attitudes and practice among currently married respondents in Uganda show that: (1) contraceptive knowledge is widespread, even among women with no education; (ii) the majority of the respondents have favourable attitudes towards contraceptive use; (iii) the level of contraceptive use is low in comparison with knowledge and attitudes. Post-primary education, ethnicity, residence, the presence of the spouse in the household and discussion of family planning with spouse were strong predictors of knowledge and favourable attitudes towards contraception. Secondary or higher education, discussion of family planning with spouse and urban residence strongly influenced contraceptive use, but child mortality did not. The use of condoms as a behavioural change to avoid contracting HIV/AIDS was low. The results suggest that, particularly in rural areas, family planning services are not meeting the needs of potential clients.

Patterns of contraceptive use in Australia: analysis of the 2001 National Health Survey.

The purpose of this paper is to review the patterns of contraceptive use in Australia, using data from a nationally representative sample of 5872 women aged 18 to 49. This survey was conducted by the Australian Bureau of Statistics in 2001 as part of the National Health Survey. Results of the analysis indicate that the oral contraceptive pill and condom were the two most frequently used methods. More than 76% of the respondents reported having ever used the pill. Over 23% of women were currently using condoms; of these 80% of the condom users used them for contraception - this included 36% who used condoms for both protection against infection and for contraception - and the remainder used them only for protection. Withdrawal was the third most popular non-surgical method up to age 40. Few women used IUDs, injections or diaphragms. Just over 3% of the respondents were using natural methods with the highest rate reported among those in their 30s. The 'morning-after pill' was reported mostly by women aged 18-24; however, there was no evidence to suggest that it was being used as a primary method of birth control. Contraceptive use declined in older women who turned to sterilization for themselves and/or their partners. Use of the contraceptive pill was somewhat higher among better-educated women, but lower among less-educated women and those from non-English-speaking backgrounds.

Knowledge of likely time of ovulation and contraceptive use in unintended pregnancies.

This investigation analyzed social and demographic characteristics of women having an unwanted or mistimed pregnancy (unintended pregnancies at the current time) in South America. A sample of 5135 women having had a normal non-malformed live-born infant were interviewed immediately postpartum at 18 hospitals participating in the Latin American Collaborative Study of Congenital Malformations (Spanish acronym: ECLAMC). Half (2568/5135 = 50%) reported that their pregnancies had been unintended, and, of those, 59.3% (1522/2568 = 59.3%) declared that they were trying to avoid conception. The latter group (n = 1522) was the main sample for this study. Patients were asked about their knowledge of when during the menstrual cycle conception is most likely to occur, their biomedical and social characteristics, the type of contraceptive methods used, their opinion of reasons for contraceptive failure, and their reasons for not using contraceptive methods. Among women with unintended pregnancies who attempted to avoid conception, only 61.6% were using contraceptive methods. Reasons given for not using contraceptives included health problems, lack of knowledge and lack of access to contraception. Women with unintended pregnancies who had not attempted to avoid conception were younger, often primigravid, less educated, and less knowledgeable concerning when during the cycle pregnancy is most likely to occur. Thus, reproductive health policies should be aimed at this target group.

Contraceptive practices of non-HIV-seropositive injecting drug users.

AIMS: To study the sociodemographic characteristics and sexual behaviours in contraception choices of injecting drug users (IDUs) and to compare the contraceptive practices of non-HIV-positive IDUs to those of the general population. DESIGN: Two surveys were used: a sample of IDUs attending 10 drug abuse treatment centres in the Paris region (IDU) and the Parisian subsample of the National French Survey of Sexual Behaviour (ACSF). MEASUREMENTS: Percentages of contraception practices were estimated separately for 81 IDU and 130 ACSF women, and for 175 IDU and 168 ACSF men, aged 25-34, not reporting prostitution or HIV seropositivity. FINDINGS: Most IDU (77%) and ACSF (84%) women, and IDU (73%) and ACSF (75%) men currently used a contraceptive method. Male condoms were more widely used by IDUs than by the general population (64 vs. 10% in women, 75 vs. 14% in men), for all subgroups of educational level, marital status, recent multipartnership status and sexual activity. CONCLUSIONS: Contraceptives are used as often by IDUs as by the general population aged 25-34. However, the methods employed differ, with higher condom use by IDUs, which suggest that IDUs take into account the risk of HIV contamination in their contraceptive practices.

Markers of platelet activation, thrombin generation and fibrinolysis in women with sickle cell disease: effects of differing forms of hormonal contraception.

OBJECTIVE: To examine laboratory markers of platelet activation, thrombin generation and fibrinolysis in women with sickle cell disease (SCD) using the combined oral contraceptive pill (COCP), progestogen only (PO) contraception and non-hormonal contraception. DESIGN: A prospective observational study set in two teaching hospitals in the London region. METHOD: Forty-four women with SCD in steady haematological state using differing hormonal contraception were recruited and venesection was performed at standardised times for the measurements of markers of platelet activation, thrombin generation and fibrinolysis. OUTCOME MEASURES: Prothrombin fragment1+2, plasmin alpha2 antiplasmin complexes, platelet factor 4 (PF-4), beta-thromboglobulin and free protein S antigen (PS-Ag). RESULTS: PS-Ag was decreased and PF-4 increased in all women while the other haemostatic variables were within normal reference ranges. However, there was no statistically significant differences in the measurements of all the haemostatic variables between the three groups of sickle cell women (Kruskal-Wallis, P > 0.05). CONCLUSION: There is anxiety about prescribing the COCP in women with SCD based on the assumption that risk of venous thromboembolism may be compounded by the underlying disease process that occurs with these women. The observed data suggest that SCD women who use the COCP have haemostatic markers which are not statistically different compared with similar women who use PO contraception or non-hormonal contraception. However, a randomized interventional trial would be necessary to evaluate further the safety aspect of COCP use in this group of women.

Transdermal contraception.

This review summarizes the clinical studies involving the once-weekly Ortho Evra/Evra contraceptive patch. The patch delivers norelgestromin (NGMN), 150 microg, and ethinyl estradiol (EE), 20 microg, daily to the systemic circulation. The contraceptive patch provided ovulation suppression and cycle control similar to that of oral norgestimate 250 microg/EE 35 microg, significantly decreased mean maximum follicular diameter following a 3-day intentional delayed dosing phase when compared with oral levonorgestrel (LNG) 50/75/125 microg/EE 30/40/30 micorg and oral LNG 100 microg/EE 20 microg, and was as effective as oral LNG 50/75/125 microg/EE 30/40/30 microg and oral desogestrel 150 microg/EE 20 microg in altering cervical mucus composition (i.e., creating a scanty, viscous consistency). The contraceptive patch provided efficacy, cycle control, and safety comparable to that seen with oral LNG 50/75/125 microg/EE 30/40/30 microg, but women were able to correctly follow the weekly dosing regimen significantly more often than the daily oral contraceptive dosing regimen. Less than 2% of patches were replaced because of complete detachment in these trials. The patch was not associated with phototoxicity or photoallergy. The contraceptive patch, the only noninvasive, weekly birth control method that a woman can self-administer, will be a valuable addition to current contraceptive options.

[Contraception in chronically ill adolescents].

Contraception in chronically ill adolescents has to consider side effects with regard to metabolic or hematological disease. Additionally the compliance of the patient has to be taken in account when consulting about contraceptives. In juvenile diabetics with good glycemic control and metabolic diseases of the amino acids oral contraceptives are justifiable. Adolescents with galactose-mia mostly suffer from premature ovarian failure and therefore have to be controlled wether they need contraception at all. Young women with sickle-cell anemia are at risk of thrombophilia. They should not be given hormonal contraceptives. In v. Willebrand-Jürgens-Syndrome oral contraceptives are favourable because it alleviates menorrhagia.

Knowledge, attitude and use of emergency contraception among female undergraduates in Eastern Nigeria.

Our objective was to investigate the knowledge, use and attitude towards emergency contraceptive pills among female undergraduates. This was done using a randomly selected sample of female undergraduate students at three tertiary institutions in Enugu, Nigeria. The majority of the respondents (95%) were aware of contraception. However, 61% of the female undergraduates had heard of emergency contraception but only 31% had actually used it. The most common source of information about emergency contraceptive pills was from friends and teachers. Most respondents (19%) used Postinor rather than other types. While using emergency contraception, 16% got pregnant, of whom 9% carried the pregnancy to term and delivered the baby while (10%) procured an illegal abortion. Increased utilization of emergency contraception is plagued with fear of infertility, anovulation, ill health and sexually transmitted infection. Though 40% of the female undergraduates accepted it when informed and would recommend it to other female students, more information dissemination is required to further create awareness and enhance wider acceptance. Awareness programmes should address the barriers to effective use of ECP preferably using peer educators and the media.

Ethnophysiology and contraceptive use among low-income women in urban Brazil.

Distrust and dissatisfaction with contraceptive methods among low-income Brazilian women contributes to incorrect contraceptive use, harmful health risks, and an extensive reliance on surgical sterilization. Data from ethnographic fieldwork in a low-income neighborhood in urban Brazil illustrate that women's concerns regarding contraception make sense in the context of their general health and illness beliefs and their understanding of reproductive physiology. Women interpret and experience biomedical concepts and contraceptive methods (such as "hormones" and oral contraceptives, respectively) according to an ethnophysiology of fecundity, menstruation, and conception. These popular representations of reproduction embody social relations and local experience and therefore persist despite the influence of biomedical models. Recognition of this ethnophysiology and greater emphasis on culturally appropriate counseling and education among health care professionals will improve women's experience and effective use of reversible contraception.
