Contraceptive Use In Women Research Articles

Contraceptive Use Among Clients of the Atlanta Feminist Women’s Health Center at Three to Five Weeks Post-Abortion

Little is known about women's contraceptive use and sexual activity in the immediate post-abortion period although effective contraceptive use is paramount during this time because fertility returns almost immediately. This study sought to learn more about women's contraceptive use and sexual behaviors to inform abortion providers and help them serve their clients better, potentially leading to a decline in the rates of unintended pregnancy and repeat abortion. Abortion clients of an Atlanta, GA clinic were surveyed over the telephone 3-5weeks post-abortion. Background information was collected from clinic medical charts. Simple and stratified frequencies and logistic regression were used to describe women's sexual activity and contraceptive use in the immediate post-abortion period and to determine if variables known at the time of the abortion could predict contraceptive use 3-5weeks post-abortion. 54.2% (n=39) of women had engaged in sexual intercourse in the immediate post-abortion period. Of these, 30.8% (n=12) were not using a contraceptive method or were not using it effectively. Women who said they did not want or need information about birth control on their medical history form were less likely to be using contraception 3-5weeks post abortion. Emphasizing the rapid return of fertility and risk of conception in pre-abortion counseling sessions could prevent future unintended pregnancies among abortion clients. Further research could explore the interaction between a willingness to talk about contraceptive methods at the time of abortion and method use post-abortion.

Factors Associated with Married Iranian Women's Contraceptive Use in Turku, Finland

Iranians are one of Finland's major immigrant groups. Like other asylum seekers in Finland, the Iranians brought with them their own cultural practices, attitudes and beliefs regarding marriage and family structure. The aim of this research was to study factors associated with married Iranian women's contraceptive use in Finland. A total of 120 married women with more than one child were interviewed in Turku, a costal city situated about 200km from Helsinki, the capital of Finland. The questionnaires gathered information about the respondents' socio-demographic status, knowledge and use of contraception, number of children, length of time in Finland, education level and other social characteristics. Our research shows that the social factors that are associated with the Iranian women's contraceptive use are mainly due to changes in their conditions of life and adaptation to the Finnish society.

Health care providers' knowledge about contraceptive evidence: a barrier to quality family planning care?

Background The underuse of effective contraceptive methods by women at risk for unintended pregnancy is a major factor contributing to the high rate of unintended pregnancy in the United States. As health care providers are important contributors to women's contraceptive use, this study was conducted to assess provider knowledge about contraception. Study Design Bivariate and multivariate analyses were performed using data collected from a convenience sample of health care providers (physicians, nurse practitioners and physician assistants) at meetings of the professional societies of family medicine and obstetrics and gynecology. Results Younger providers were more knowledgeable, as were obstetrician/gynecologists, female providers and providers who provide intrauterine contraception in their practice. Conclusions The lack of consistent and accurate knowledge about contraception among providers has the potential to dramatically affect providers' ability to provide quality contraceptive care for their patients, which could have an impact on their ability to prevent unintended pregnancies.

Area disadvantage, socioeconomic position and women's contraception use: a multilevel study in the UK

Background and methodologyThis study aimed to investigate associations between area-level socioeconomic disadvantage (central heating, car ownership and residents in professional occupations), individual-level socioeconomic position (social class and educational qualifications) and...

Contraceptive use among women on a Tanzanian sugar plantation

Contraceptive use is low in Tanzania, despite many women's interest in limiting family size. Our objective is to examine how, in an agricultural plantation context, women's contraceptive use is associated with pregnancy intention, decision making power over contraception and family size.

Changing patterns of contraceptive use in Australian women

Background This longitudinal analysis examines how patterns of contraceptive use changed over 11 years among Australian women born between 1973 and 1978. Study Design The analysis included 6708 women sampled from the Australian universal health insurance database who completed four self-report postal surveys between 1996 and 2006. Change over time in use of any method of contraception and the common single methods of the oral contraceptive pill and condom was examined using a longitudinal logistic regression model. Results The oral contraceptive pill was the most commonly used single method at each survey (27–44%) but decreased over time. Over time, contraceptive users were increasingly more likely to be single or in a de facto relationship or to have had two or more births. Conclusions Women's contraceptive use and the factors associated with contraceptive use change over time as women move into relationships, try to conceive, have babies and complete their families.

Contraceptive Use in Women Enrolled into Preventive HIV Vaccine Trials: Experience from a Phase I/II Trial in East Africa

BackgroundHIV vaccine trials generally require that pregnant women are excluded from participation, and contraceptive methods must be used to prevent pregnancy during the trial. However, access to quality services and misconceptions associated with contraceptive methods may impact on their effective use in developing countries. We describe the pattern of contraceptive use in a multi-site phase I/IIa HIV Vaccine trial in East Africa (Uganda, Kenya and Tanzania) and factors that may have influenced their use during the trial.MethodsPregnancy prevention counseling was provided to female participants during informed consent process and at each study visit. Participants' methods of contraception used were documented. Methods of contraceptives were provided on site. Pregnancy testing was done at designated visits during the trial. Obstacles to contraceptive use were identified and addressed at each visit.ResultsOverall, 103 (31.8%) of a total of 324 enrolled volunteers were females. Female participants were generally young with a mean age of 29(±7.2), married (49.5%) and had less than high school education (62.1%). Hormonal contraceptives were the most common method of contraception (58.3%) followed by condom use (22.3%). The distribution of methods of contraception among the three sites was similar except for more condom use and less abstinence in Uganda. The majority of women (85.4%) reported to contraceptive use prior to screening. The reasons for not using contraception included access to quality services, insufficient knowledge of certain methods, and misconceptions.ConclusionAlthough hormonal contraceptives were frequently used by females participating in the vaccine trial, misconceptions and their incorrect use might have led to inconsistent use resulting in undesired pregnancies. The study underscores the need for an integrated approach to pregnancy prevention counseling during HIV vaccine trials.Trial RegistrationClinicalTrials.gov NCT00123968

Symptomatic ileofemoral DVT after onset of oral contraceptive use in women with previously undiagnosed May-Thurner Syndrome

May-Thurner syndrome is characterized by left common iliac obstruction secondary to compression of the left iliac vein by the right common iliac artery against the fifth-lumbar vertebra. This anatomic variant results in an increased incidence of left-sided deep venous thrombosis (DVT). Furthermore, while a preponderance of left-sided DVT has been demonstrated in women during pregnancy and oral contraceptive use, patients are not typically screened for this condition after developing a left-sided DVT. As anticoagulation alone is ineffective for DVT treatment in the setting of May-Thurner anatomy, more aggressive treatment is warranted. Failure to diagnosis this condition predisposes these women to the unnecessary risks of recurrent DVT and post-thrombotic syndrome. We present the occurrence of 7 adolescent patients with previously undiagnosed May-Thurner syndrome who presented with DVT after the initiation of oral contraceptive steroids (OCP) use. All 7 patients elected to proceed with mechanical thrombolysis/catheter based thrombolysis followed by endovascular stenting and were postoperatively treated with 6 months of warfarin. Mean patient age was 18.3 +/- 3.3 years (range, 16-24 years). Mean time to presentation after initiation of OCP was 5 weeks (range, 2-10 weeks). Mean time to intervention was 16.8 days (range, 10-24 days). All patients were treated with mechanical thrombectomy. Our rate of intraoperative clot resolution was 100%. All 7 patients were treated with self expanding nitinol stents after angioplasty of the iliac vein stenosis with resolution of the stenotic segment. Primary stent patency is 100% (7/7). Mean follow-up time is 13 +/- 13.84 months (range, 6-42 months). There have been no long-term complications related to surgical treatment or anticoagulation. All 7 patients have experienced resolution of left leg swelling and pain and have no evidence of post-thrombotic syndrome or DVT recurrence to date. Women on OCPs presenting with left-sided iliofemoral DVT should be screened for hypercoagulable disorders and underlying May-Thurner anatomy. Treatment of May-Thurner syndrome should include thrombolysis/thrombectomy and anticoagulation for current DVT in addition to angioplasty and stenting of the underlying obstruction.

Contraception for Women Who Receive Anticoagulant Therapy for Venous Thrombosis

For women with histories of venous thromboembolism (VTE) who require anticoagulant therapy, choosing appropriate contraception can be challenging. WHO investigators reviewed publications that addressed contraceptive use in women who received anticoagulant therapy for current VTE, those who received such therapy for other indications (e.g., prosthetic heart valves), and those with heavy menstrual bleeding associated with disorders such as von Willebrand disease. Highlights of the WHO observations and recommendations are:

Intimate Partner Violence and Women's Contraceptive Use

Intimate partner violence has been hypothesized as a factor associated with women's risk for problems in contraception use or access. This article explores differences in contraceptive use between abused and nonabused women, using a case-control study of 225 women. Women experiencing physical and emotional abuse were more likely to report not using their preferred method of contraception in the past 12 months compared with nonabused women (OR = 1.9; 95% CI = 1.0 to 3.7). Health care providers need to consider how intimate partner violence may influence their patients' use of contraceptives, which has implications for the high risk of unintended pregnancies among abused women.

Gender equity and women's contraception use

Gender equity describes the distribution between men and women of social and material resources and decision‐making powers. Women's experiences of gender equity are likely to influence their contraceptive use. Multilevel analysis of two databases: the National Survey of Sexual Attitudes and Lifestyles from the United Kingdom and the United Nations' Fertility and Family Surveys, was undertaken to explore the association between gender equity measured at two spatial scales (small areas and countries) and women's contraception use. Results suggest that the spatial scale at which gender equity is considered is important. Gender equity was associated with contraception use at a local level, but not at the country level. Further, gender equity (at a local level) benefited women with less education in terms of increasing their likelihood of contraception use compared with more highly educated women. Results suggest gender equity is a potential pathway to reducing socio‐economic inequalities in health in developed settings.

Hormonal Contraception

Hormonal contraceptives have been a part of clinical practice for more than 40 years, and family planning programs, based largely on contraceptive provision, are regarded as one of the most successful public health interventions of the 20th century. Thus, discussion of family planning issues and contraceptive considerations has become an integral component of women's health care and one of the benchmarks of the traditional annual well-women visit. In terms of cost-effectiveness, prevention of unplanned pregnancies through contraceptive use has repeatedly been shown to be a highly cost-effective use of health care dollars. Options for effective hormonal contraception have expanded tremendously and include a variety of delivery options, including the pills both in traditional 21/7 format, and more recently in a 24/4 format, as well as a vaginal ring, a skin patch, implants, and the hormonally medicated intrauterine device. Importantly, the overall risks associated with hormonal contraceptives have been reduced as compared with older formulations, even for women with medical conditions. Many modern hormonal contraceptives also offer valuable noncontraceptive benefits. To help clinical decision making, a number of evidence-based guides have been published, and the American College of Obstetricians and Gynecologists has recently updated their practice bulletin on contraception use in women with medical conditions. In general, clinical protocols for provision of hormonal contraceptives have been streamlined, and unnecessary practices, tests, and procedures are identified and discouraged. In this review, we will summarize both technical and programmatic aspects of hormonal contraceptive use, and methods are discussed in order of efficacy from highest to lowest.

Synergistic Effects of Hypofibrinolysis and Genetic and Acquired Risk Factors on the Risk of a First Venous Thrombosis

BackgroundPreviously, we demonstrated that hypofibrinolysis, a decreased capacity to dissolve a blood clot as measured with an overall clot lysis assay, increases the risk of venous thrombosis. Here, we investigated the combined effect of hypofibrinolysis with established risk factors associated with hypercoagulability.Methods and FindingsFibrinolytic potential was determined with a plasma-based clot lysis assay in 2,090 patients with venous thrombosis and 2,564 control participants between 18 and 70 y of age enrolled in the Multiple Environmental and Genetic Assessment (MEGA) of risk factors for venous thrombosis study, a population-based case-control study on venous thrombosis. Participants completed a standardized questionnaire on acquired risk factors.Hypofibrinolysis alone, i.e., clot lysis time (CLT) in the fourth quartile (longest CLT) (in absence of the other risk factor of interest) increased thrombosis risk about 2-fold relative to individuals with CLT in the first quartile (shortest CLT). Oral contraceptive use in women with CLT in the first quartile gave an odds ratio (OR) of 2.6 (95% confidence interval [CI] 1.6 to 4.0), while women with hypofibrinolysis who used oral contraceptives had an over 20-fold increased risk of venous thrombosis (OR 21.8, 95% CI 10.2 to 46.7). For immobilization alone the OR was 4.3 (95% CI 3.2 to 5.8) and immobilization with hypofibrinolysis increased the risk 10.3-fold (95% CI 7.7 to 13.8). Factor V Leiden alone increased the risk 3.5-fold (95% CI 2.3 to 5.5), and hypofibrinolysis in factor V Leiden carriers gave an OR of 8.1 (95% CI 5.3 to 12.3). The combination of hypofibrinolysis and the prothrombin 20210A mutation did not synergistically increase the risk. All ORs and 95% CIs presented are relative to individuals with CLT in the first quartile and without the other risk factor of interest.ConclusionsThe combination of hypofibrinolysis with oral contraceptive use, immobilization, or factor V Leiden results in a risk of venous thrombosis that exceeds the sum of the individual risks.

Reproductive history, sexual behavior and use of contraception in women with epilepsy

BackgroundWomen with epilepsy experience more pregnancy-related risks than do their healthy peers. Guidelines recommend highly effective contraception. However, their contraceptive practices remain unknown. Study DesignWe conducted a cross-sectional questionnaire study among reproductive-age women (18–44 years) with epilepsy presenting for routine, outpatient visits to an urban, academic medical center. Our questionnaire, in English or Spanish, included demographic characteristics, reproductive history, antiepileptic drug use, sexual behavior and contraception. ResultsParticipants had a mean age of 32 years (S.D.=8), 32% spoke Spanish and described themselves as Hispanic. Participants reported a wide range of educational attainment, insurance payor and income.About half of the participants reported at least one pregnancy, and 50% of the 181 pregnancies reported were unplanned. Among the 53% who reported intercourse in the last month, 74% used contraception, 15% were pregnant, 5% did not want to use contraception, 3% sought pregnancy and 3% had hysterectomy. Of those using contraception, 53% used highly effective methods (sterilization, intrauterine device, hormonal pill, patch and injection), and 47% used less effective methods (condom, withdrawal, rhythm and spermicide). Among the 21 participants using hormonal methods, six concomitantly took enzyme-inducing antiepileptic drugs potentially increasing susceptibility to pregnancy. DiscussionIn this sample of women with epilepsy about half reported prior pregnancies; 50% were unplanned. Of those using contraception, only 53% used a highly effective method. Future studies should determine generalizability of these findings and explore reasons for inadequate family planning in women with epilepsy.

Religious beliefs prevailing among Somali men living in Finland regarding the use of the condom by men and that of other forms of contraception by women

The objective of this study was to explore religious beliefs of Somali men residing in Finland that may influence their use of condoms and their perceptions of contraceptive use by women of their community. Both quantitative and qualitative methods were used to study 98 refugee Somali married men aged 30–65 years. Participants filled in self-administered questionnaires (in English or in Somali) but were also interviewed. The interviews were semi-structured, featuring thematically clustered open-ended questions; they were conducted in Somali or in English. Participants had arrived in Finland between 1990–1998. They had from 2–12 children. For religious reasons, 63% of the men avoided using condoms and were opposed to women's contraceptive use. The remaining 37% were not deterred by religious beliefs from using condoms and from approving women's contraceptive practices. In conclusion, for religious reasons, most Somali men assessed avoided using condoms and disapproved of the use of contraception by women.

Masked Hypertension Definition, Impact, Outcomes: A Critical Review

The phenomenon of masked hypertension (MH) is defined as a clinical condition in which a patient's office blood pressure (BP) level is <140/90 mm Hg but ambulatory or home BP readings are in the hypertensive range. The prevalence in the population is about the same as that of isolated office hypertension; about 1 in 7 or 8 persons with a normal office BP level may fall into this category. The high prevalence of MH would suggest the necessity for measuring out-of-office BP in persons with apparently normal or well-controlled office BP. Reactivity to daily life stressors and behavioral factors such as smoking, alcohol use, contraceptive use in women, and sedentary habits can selectively influence MH. MH should be searched for in individuals who are at increased risk for cardiovascular complications including patients with kidney disease or diabetes. Individuals with MH have been shown to have a greater-than-normal prevalence of organ damage, particularly with an increased prevalence of metabolic risk factors, left ventricular mass index, carotid intima-media thickness, and impaired large artery distensibility compared with patients with a truly normal BP level in and out of the clinic or office. Also, outcome studies have suggested that MH increases cardiovascular risk, which appears to be close to that of in-office and out-of-office hypertension. The aim of this review was to define the entity of MH, to describe its prevalence in the general population, and to discuss its correlation with cardiovascular events.

The Effects of Government Policies towards Contraception Use in Women

La educación es considerada un factor muy importante en la relación entre el nivel de natalidad y el uso de anticonceptivos en un país. El propósito de este artículo es analizar si los niveles de natalidad son reducidos debido a las políticas gubernamentales, específicamente, el apoyo directo hacia el control de natalidad en comparación a los países que dan apoyo indirecto. Por lo tanto, en el presente documento se comparan Honduras y Belice, que proporcionan apoyo directo e indirecto a la anticoncepción, respectivamente. Primero, el coeficiente en la variable de nacionalidad nos dice si las mujeres en Honduras están usando más anticonceptivos que las mujeres en Belice. Segundo, después de utilizar un modelo Poisson, encontramos que aunque Honduras da apoyo directo para el uso de métodos anticonceptivos, no hay diferencia entre los niveles de natalidad en Honduras en comparación con Belice, .188 (p < 0.1) Tercero, aunque Honduras da subsidios directos para anticonceptivos y Belice da subsidios indirectos, no hay diferencia en la frecuencia de uso de anticonceptivos entre las mujeres de Honduras en comparación con las mujeres de Belice, 0.567 (p < 0.1). Como el coeficiente en nacionalidad resultó estadísticamente insignificante en los dos modelos, podemos concluir que el factor determinante en la reducción de los niveles de natalidad en los países es la efectividad de los programas de anticoncepción, sin importar el tipo de apoyo que el gobierno da a las mujeres. Los gobiernos pueden hacer sus programas más efectivos si los complementan con la escolaridad. Estos programas de educación adjunto con programas de anticoncepción efectivos, pueden enseñar tanto a las niñas como a las mujeres los beneficios que se obtienen al limitar su comportamiento reproductivo.

Relationship between Leptin and C-Reactive Protein in Young Finnish Adults

Leptin and C-reactive protein (CRP) concentrations are increased in inflammation, and both have been linked to increased risk for cardiovascular diseases. The objective of the study was to explore in a population-based sample whether the relation between leptin and CRP is independent of obesity level and whether genetic causes of CRP elevation contribute to leptin levels. This was a population-based study including 1862 young adults (971 women; 891 men) aged 24-39 yr. The study was conducted at five centers in Finland. Associations between leptin and CRP adjusted for obesity indices, risk factors, genetic variables, and lifestyle variables were measured. Women had 3.0-fold higher median concentrations of leptin (12.5 vs. 4.1 ng/ml) and 1.3-fold higher median concentrations of CRP (0.75 vs. 0.56 mg/liter) than men (P < 0.0001 in both comparisons). In univariate analyses, CRP and leptin were significantly intercorrelated (r = 0.47, P < 0.0001 for women; r = 0.46, P < 0.0001 for men). In multiple regression analysis including age, body mass index, waist circumference, insulin, lipids, systolic and diastolic blood pressures, smoking status, and use of oral contraceptives in women, leptin was the main determinant of CRP in men (P < 0.0001) and the second most important determinant in women (P < 0.0001). A Mendelian randomization test based on genetic variants in the CRP gene (five single nucleotide polymorphisms) provided no support for CRP as a causal agent for leptin. Leptin, obesity, and oral contraceptive use in women were the main factors related to CRP. The relation between leptin and CRP was independent of obesity and cardiovascular risk factors.

Contraceptive Discontinuation and Failure and Subsequent Abortion in Romania: 1994–99

This study examines the levels and correlates of contraceptive failure and discontinuation in Romania, together with the consequences of contraceptive method failure in terms of induced abortion. Of special interest are women who rely on the traditional method of withdrawal and the proportion of withdrawal failures resulting in abortion. Our analysis is based on multiyear calendar data concerning women's contraceptive use and monthly reproductive behaviors collected in the 1999 Romanian Reproductive Health Survey. Weibull regression models are estimated to analyze the determinants of discontinuation and failure for all methods combined and for withdrawal. Overall, 19 and 28 percent of women became pregnant within the first year of using any contraceptive method and of practicing withdrawal, respectively. About 57 and 59 percent of failures from use of all methods and from withdrawal ended in abortion, accounting for 30 percent and 22 percent, respectively, of all abortions reported between 1994 and 1999. These findings suggest that high rates of contraceptive discontinuation and failure contributed significantly to the widespread reliance on induced abortion among Romanian women during this period.

U.S. Women’s One‐Year Contraceptive Use Patterns, 2004

Unintended pregnancies occur far too often in the United States, and half occur when couples fail to practice contraception. Improved measures of the continuity of women's contraceptive use, nonuse and switching patterns can help identify ways to reduce unintended pregnancy. A nationally representative sample of 1,978 adult women at risk of unintended pregnancy was surveyed by telephone in 2004. Respondents provided detailed information about contraceptive use and periods of stopping or switching methods during the past year. A typology of patterns of contraceptive use was created, classifying women into mutually exclusive categories according to their exposure to pregnancy risk. Twenty-three percent of women at risk of unintended pregnancy were exposed to a high risk of pregnancy because of gaps in contraceptive method use in the year prior to the survey--8% were consistent nonusers, and 15% experienced 1-11 months of nonuse while at risk. More than half of women used a method during each of the previous 12 months-38% used the same method or methods all year, and 24% switched methods. Fifteen percent of women had gaps in contraceptive use when they were not at risk. Women reported a variety of reasons for their gaps in contraceptive use, including method-related difficulties and side effects, infrequent sex and being ambivalent about avoiding pregnancy. Strategies for reducing gaps in contraceptive use include improved counseling to help women both choose the right method and continue method use, especially when they have periods of infrequent sexual activity or are experiencing method-related side effects or problems.
