Prevention of unintended pregnancy: a focus on long-acting reversible contraception

Relationship between health insurance enrolment and unintended pregnancy in Ghana

CONTEXT

The effect of health insurance coverage on sexual and reproductive health, especially unintended pregnancy, has scantly been researched. Using the 2014 Ghana Demographic and Health Survey, the study examined the links between women's health insurance enrolment on unintended pregnancy in Ghana.

METHOD

The sample consisted of 9,396 women aged 15-49 years, but the analysis was limited to the 4,544 women who were pregnant in the two years preceding the survey. The effects of health insurance enrolment on unintended pregnancy was examined with the propensity score matching. The health insurance enrolment was the treatment variable and unintended pregnancy as the outcome variable.

RESULTS

This study showed that 66.0% of all women surveyed had health insurance coverage and 31.8% of all women of childbearing age who were currently or had previously been pregnant reported having at least one unintended pregnancy. Thirty percent of insured women had an unintended pregnancy, compared to 37% of uninsured women. The results showed that education, household wealth index, religion, and type of marital union were significant predictor of health insurance coverage among Ghanaian women. The PSM split the women based on their health insurance status. After matching, the difference between the insured and uninsured women reduces significantly. Results demonstrated that, the probability of unintended pregnancy was 0.312 among insured women and 0.351 among those not insured in Ghana. This implies that having health insurance coverage will help in reducing the likelihood of women experiencing unintended pregnancy.

CONCLUSIONS

Results highlight the importance of the target of universal health coverage under the sustainable development goal 3 and demonstrate that expanding existing health insurance schemes within Ghana could contribute to reducing the number unintended pregnancies experienced each year.

Contraceptive method type and satisfaction, confidence in use, and switching intentions

OBJECTIVE

We examined whether contraceptive method type, satisfaction with use, and confidence in correct use were independently associated with switching intentions, a precursor of switching behaviors.

STUDY DESIGN

Data were from a probability-based sample survey carried out in Delaware and Maryland in 2016 and 2017 among women ages 18 to 44. Women's current contraceptive methods were classified into 5 categories: coitally-dependent methods (barrier methods, withdrawal, and natural family planning); oral contraceptive pills, patches, and rings; injections; implants; and intrauterine contraception (IUC). Satisfaction, confidence, and switching intentions were dichotomized into being very versus less satisfied, being completely versus less confident, and having very low versus not very low switching intentions. We conducted binomial logistic regression to examine whether method type, satisfaction, and confidence were independently associated with having very low switching intentions, adjusting for a range of covariates including sociodemographics, perceived health, religious attendance frequency, sexual, contraceptive, and reproductive experiences, and state of residence (Maryland or Delaware).

RESULTS

Among 1,077 women using reversible contraception, those using IUC relative to implants, pills, patches, or rings, and coitally-dependent methods were more likely to have very low switching intentions. Among all survey respondents, those who were very satisfied and those who were completely confident in correct use were also more likely to report very low switching intentions.

CONCLUSIONS

Using IUC, being very satisfied, and being very confident in correct use were independently associated with having very low switching intentions.

IMPLICATIONS

These results suggest that those using IUC have very low intentions to switch for reasons in addition to satisfaction-level with their method. Other aspects of using IUC such as ease of use, perceived barriers to switching, or having very low switching intentions before beginning IUC may be such reasons.

Design, Synthesis, and in Vitro and in Vivo Evaluation of Ouabain Analogues as Potent and Selective Na,K-ATPase α4 Isoform Inhibitors for Male Contraception

Na,K-ATPase α4 is a testis-specific plasma membrane Na⁺ and K⁺ transporter expressed in sperm flagellum. Deletion of Na,K-ATPase α4 in male mice results in complete infertility, making it an attractive target for male contraception. Na,K-ATPase α4 is characterized by a high affinity for the cardiac glycoside ouabain. With the goal of discovering selective inhibitors of the Na,K-ATPase α4 and of sperm function, ouabain derivatives were modified at the glycone (C3) and the lactone (C17) domains. Ouabagenin analogue 25, carrying a benzyltriazole moiety at C17, is a picomolar inhibitor of Na,K-ATPase α4, with an outstanding α4 isoform selectivity profile. Moreover, compound 25 decreased sperm motility in vitro and in vivo and affected sperm membrane potential, intracellular Ca²⁺, pH, and hypermotility. These results proved that the new ouabagenin triazole analogue is an effective and selective inhibitor of Na,K-ATPase α4 and sperm function.

Pharmacologic Therapies in Women's Health: Contraception and Menopause Treatment

Female hormones play a significant role in the etiology and treatment of many women's health conditions. This article focuses on the common uses of hormonal therapy. When prescribing estrogen-containing regimens throughout the span of a woman's life, the risks are similar (ie, cardiovascular risk and venous thromboembolism), but the degree of risk varies significantly depending on a woman's particular set of risk factors and the details of the hormone regimen. In addition to estrogens and progestogens, this article also touches on the use of selective steroid receptor modulators in emergency contraception and in treatment of menopause symptoms.

Projections and opinions from 100 experts in long-acting reversible contraception

OBJECTIVE

This survey of published researchers of long-acting reversible contraceptives (LARCs) examines their opinions about important barriers to LARC use in the United States (US), projections for LARC use in the absence of barriers and attitudes toward incentives for clinicians to provide and women to use LARC methods.

STUDY DESIGN

We identified 182 authors of 59 peer-reviewed papers on LARC use published since 2013. A total of 104 completed an internet survey. We used descriptive and multivariate analyses to assess LARC use barriers and respondent characteristics associated with LARC projections and opinions.

RESULTS

The most commonly identified barrier was the cost of the device (63%), followed by women's knowledge of safety, method acceptability and expectations about use. A shortage of trained providers was a commonly cited barrier, primarily of primary care providers (49%). Median and modal projections of LARC use in the absence of these barriers were 25-29% of contracepting women. There was limited support for provider incentives and almost no support for incentives for women to use LARC methods, primarily out of concern about coercion.

CONCLUSIONS

Clinical and social science LARC experts project at least a doubling of the current US rate of LARC use if barriers to method provision and adoption are removed. While LARC experts recognize the promise of LARC methods to better meet women's contraceptive needs, they anticipate that the majority of US women will not choose LARC methods. Reducing unintended pregnancy rates will depend on knowledge, availability and use of a wider range of methods of contraception to meet women's individual needs.

IMPLICATIONS

Efforts to increase LARC use need to meet the dual goals of increasing access to LARC methods and protecting women's reproductive autonomy. To accomplish this, we need reasonable expectations for use, provider training, low-cost devices and noncoercive counseling, rather than incentives for provision or use.

Working with State Health Departments on Emerging Issues in Maternal and Child Health: Immediate Postpartum Long-Acting Reversible Contraceptives

BACKGROUND

Immediate postpartum long-acting reversible contraceptives (LARC) are highly effective in preventing unintended pregnancy. State health departments are in the process of implementing a systems change approach to better apply policies supporting the use of immediate postpartum LARC.

METHODS

Beginning in 2014, a group of national organizations, federal agencies, and six states have convened a LARC Learning Community to share strategies and best practices in immediate postpartum LARC policy development and implementation. Community activities consist of in-person meetings and a webinar series as forums to discuss systems change.

RESULTS

The Learning Community identified eight domains for discussion and development of resources: training, pay streams, stocking and supply, consent, outreach, stakeholder partnerships, service location, and data and surveillance. The community is currently developing resource materials and guidance for use by other state health departments.

CONCLUSIONS

To effectively implement policies on immediate postpartum LARC, states must engage a number of stakeholders in the process, raise awareness of the challenges to implementation, and communicate strategies across agencies during policy development.

Complementary and Alternative Medicine Use Among Women During Pregnancy and Childbearing Years

OBJECTIVES

Little is known regarding complementary and alternative medicine (CAM) use during pregnancy and the preconception period. Since half of all pregnancies in the United States are unintended, understanding the patterns of CAM use among women of childbearing age has implications for fetal and maternal health.

METHODS

Descriptive statistics were generated from the 2012 National Health Interview Study (NHIS) to estimate weighted prevalence and patterns of CAM use by women of childbearing age. Comparisons were made between pregnant and nonpregnant respondents.

RESULTS

In this sample of 10,002 women, 7 percent (n = 727) were recently pregnant. Over one-third of all the women used CAM during the previous year (34/38%, pregnant/nonpregnant, respectively) and only half disclosed CAM use to conventional providers (50/49%). In the adjusted model, taking multivitamins (OR 2.52 [CI 2.22-2.86]) and moderate to heavy alcohol use (OR 1.92 [CI 1.53-2.41]) were more likely associated with CAM use. The two most commonly used modalities were herbs (14/17%) and yoga (13/16%). The top reasons for CAM use were to improve general wellness or to prevent disease (33/35%) and to treat back pain (16/18%). When examining all pregnancy-related symptoms treated with CAM, no difference was found in the rates of CAM use between pregnant and nonpregnant users.

CONCLUSIONS

CAM use by women of childbearing age in the United States is common, with over a third of the population using one or more therapies. However, only half disclosed their use to conventional providers despite limited evidence on safety and effectiveness. This study highlights the important need for further research in this area.

Reproductive issues in sickle cell disease

As medical advances improve survival, reduce disease-related morbidity, and improve quality of life, reproductive issues will take higher priority in the sickle cell disease (SCD) community. A wide variety of topics are addressed in this chapter, including fertility, gonadal failure, erectile dysfunction, and menstrual issues in SCD. Etiologies of impaired male fertility are multifactorial and include hypogonadism, erectile dysfunction, sperm abnormalities, and complications of medical therapies. Much less is known about the prevalence and etiology of infertility in women with SCD. Other reproductive issues in women included in this review are pain and the menstrual cycle, contraception, and preconception counseling. Finally, long-term therapies for SCD and their impact on fertility are presented. Transfusional iron overload and gonadal failure are addressed, followed by options for fertility preservation after stem cell transplantation. Focus is placed on hydroxyurea therapy given its benefits and increasing use in SCD. The impact of this agent on spermatogenesis, azoospermia, and the developing fetus is discussed.
