More comprehensive sex education reduced teen births: Quasi-experimental evidence

Federated difference-in-differences with multiple time periods in DataSHIELD

Difference-in-differences (DID) is a key tool for causal impact evaluation but faces challenges when applied to sensitive data restricted by privacy regulations. Obtaining consent can shrink sample sizes and reduce statistical power, limiting the analysis's effectiveness. Federated learning addresses these issues by sharing aggregated statistics rather than individual data, though advanced federated DID software is limited. We developed a federated version of the Callaway and Sant'Anna difference-in-differences (CSDID), integrated into the DataSHIELD platform, adhering to stringent privacy protocols. Our approach reproduces key estimates and standard errors while preserving confidentiality. Using simulated and real-world data from a malaria intervention in Mozambique, we demonstrate that federated estimates increase sample sizes, reduce estimation uncertainty, and enable analyses when data owners cannot share treated or untreated group data. Our work contributes to facilitating the evaluation of policy interventions or treatments across centers and borders.

Sex Educators' Strategies for Building Student Trust

Although clinicians have been the focus of research on trust in health care, much of the health guidance Americans receive occurs outside clinical settings. School-based health education is one such setting. Given the importance of interpersonal dynamics to clinicians' work, trust likely features heavily in achieving health educators' outcomes. This study asks: How do health educators approach building trust with students? In interviews with 39 sexual health educators in Ohio and Illinois, I find that educators report several strategies that they use in their attempt to build student trust: They use personal anecdotes and informality to distinguish themselves from teachers; adjust their approach based on their race, gender, or age if they perceive these identities impede trust; and emphasize lessons are factual when facing pushback. My findings reveal key differences in how clinicians and nonclinical professionals approach trust and more broadly, how organizational factors impact health professionals' approach to trust.

Forbidden Conversations: A Comprehensive Exploration of Taboos in Sexual and Reproductive Health

This scoping review aims to comprehensively explore the landscape of taboos and their impact on sexual and reproductive health. Titled "Forbidden Conversations," it delves into the intricate web of societal, cultural, and religious norms that have contributed to the elusive and often stigmatized nature of sexual and reproductive health topics. The review navigates through the multifaceted dimensions of these taboos, shedding light on their impact on individuals, communities, and public health while advocating for a paradigm shift toward open, inclusive, and informed dialogue. The analysis within this review spans a decade, capturing the most recent and relevant literature to map the landscape of taboos in sexual and reproductive health. It explores the persistent societal apprehensions and subsequent stigmatization surrounding topics such as menstruation, contraception, fertility, sexual orientation, and gender identity. The review contextualizes the multifaceted challenges presented by these prevailing norms by tracing historically rooted taboos and their evolution across different cultures and contexts. The scoping review identifies the profound implications of these taboos on public health, highlighting how they contribute to disparities in access to healthcare, perpetuate misinformation, and infringe upon the fundamental rights of individuals. It addresses the challenges in sexual education, emphasizing how these taboos impede comprehensive understanding and enforcement of sexual and reproductive health rights among adolescents and young adults. The intersectional approach taken in this review situates these taboos within broader systems of inequality, emphasizing the compounded impact they have on marginalized populations. Through this comprehensive exploration, the review aims to provide actionable insights and identify existing research, policy, and practice gaps. It seeks to lay the foundation for future initiatives that advocate for destigmatization, empowerment, and equity in sexual and reproductive health. Ultimately, "Forbidden Conversations" aims to steer the conversation toward openness and inclusivity while advocating for unbiased, comprehensive sexual and reproductive healthcare with dignity for all individuals.

Use of infant simulators as an aid in pregnancy and parenting educational interventions for school-aged students: a scoping review

Schools and school teachers often focus on content aimed at delaying sexual debut and preventing teenage pregnancy, and address the impacts of risky behaviours on infant health. Infant simulators are increasingly used in health education courses. However, it is unclear how effective this education is. In this review, we examined the evidence for the effectiveness and use of pregnancy/parenting education programmes for school-aged students using infant simulators. Infant simulators are lifelike replicas of human newborn babies that have electronic capacity to mimic a range of infant behaviours. These may include feeding, comfort needs and nappy changing. Responses to these replicated behaviours may be recorded to provide feedback of the adequacy of the response for educational purposes and provide feedback to prospective parents and caregivers. This review followed the guidelines for conducting a scoping review developed by Joanna Briggs Institute (JBI). After following the process as recommended by the JBI, 32 eligible articles were selected for inclusion. Eight themes emerged from the analysis and it was found that the use of infant simulators in terms of effectiveness was not conclusive. This may be due to lack of longitudinal studies examining the impact of the education provided. Furthermore, the literature did not address innovations of infant simulators that replicate infants with particular characteristics, those with fetal alcohol spectrum disorder, shaken baby syndrome or challenges from parental substance use. Further research is required to determine the long-term impact of using infant simulators on reducing risky behaviours. Given these challenges, it is important to support initiatives for sex, pregnancy and parenting education among all students.

Sexuality education for school-aged children and adolescents: A concept analysis

PURPOSE

Sexuality education is essential for children and adolescents to make better choices regarding their sexual well-being. Parents, teachers, and healthcare providers are not always comfortable talking to school-age children about sex, making sexuality education a concept of interest to be explored. The purpose of this paper is to explain the concept of sexuality education in school-aged children and adolescents.

DESIGN AND METHODS

This paper uses Walker and Avant's concept analysis to help clarify its meaning. The sexuality education concept is explored in this article in the views of educating school systems K-12 with three types of sexuality education (abstinence-only, abstinence-plus, and comprehensive sexuality education). Literature from 1990 to 2023 was retrieved using PubMed, Google Scholar, and CINAHL.

RESULTS

A model case is used to demonstrate the importance of sexuality education. A borderline case and a related case are proposed to explain other uses of the concept. Defining attributes, antecedents, consequences, and empirical referents are explored. Antecedents of sexuality education are grouped into three categories: resources, political environment, and social beliefs.

PRACTICE IMPLICATIONS

A conceptual understanding of sexuality education can foster nurses' confidence in talking to their patients about this topic and encourage nurses to advocate for comprehensive sexuality education nationwide.

Prevalence and Factors Associated With Adolescent Pregnancy Among an Indigenous Ethnic Group in Rural Nepal: A Community-based Cross-sectional Study

OBJECTIVES

The Chepang people, an indigenous ethnic group in Nepal, experience substantial marginalization and socioeconomic disadvantages, making their communities among the most vulnerable in the region. This study aimed to determine the prevalence and factors associated with adolescent pregnancy in the Chepang communities of Raksirang Rural Municipality, Makwanpur District, Bagmati Province, Nepal.

METHODS

A cross-sectional study was conducted from October 2022 to April 2023 among 231 Chepang women selected using simple random sampling from Raksirang Rural Municipality. A semi-structured questionnaire was used for interviewing the mothers. Bivariate and multivariate logistic regression analyses were performed, using odds ratios with 95% confidence intervals (CIs). Variables with a variation inflation factor of more than 2 and a p-value of more than 0.25 were excluded from the final model.

RESULTS

The study revealed that the prevalence rate of adolescent pregnancy among Chepang women was 71.4% (95% CI, 65.14 to 77.16). A large percentage of participants (72.7%) were married before the age of 18 years. Poor knowledge of adolescent pregnancy (adjusted odds ratio [aOR], 10.3; 95% CI, 8.42 to 14.87), unplanned pregnancy (aOR, 13.3; 95% CI, 10.76 to 19.2), and lack of sex education (aOR, 6.57; 95% CI, 3.85 to 11.27) were significantly associated with adolescent pregnancy.

CONCLUSIONS

The prevalence of adolescent pregnancy among the Chepang community was high. These findings highlighted the importance of raising awareness about the potential consequences of adolescent pregnancy and implementing comprehensive sexuality education programs for preventing adolescent pregnancies within this community.

Protocol for designing and evaluating an undergraduate public health course on sexual and reproductive health at a public university in California

Introduction

Comprehensive sexuality education (CSE) is associated with positive sexual and reproductive health (SRH) outcomes, including increased contraceptive use, lower rates of unintended pregnancy and prevention of sexual violence. However, implementation of and requirements for CSE vary across the United States which can negatively impact students, both during and beyond high school, including among college students.

Methods

and Analysis: This paper describes the research protocol for a multi-staged approach for designing, implementing and evaluating an SRH course for up to 60 undergraduate students at a public university in California. Before the class is offered, we will conduct 20 in-depth interviews with current students, educators and course design experts to learn from their experiences and seek their guidance on course design. To evaluate the course, enrolled students will complete a pre-course and a post-course survey before and after class is taught, to assess students' attitudes and values relevant to educational concepts and the format and delivery of the course and its modules and activities. Approximately 20 students will take part in an in-depth exit interview, after completing the course, to gather perceptions about how the course impacted their knowledge and behavior. The goal is to refine materials for future in-person course offerings and develop a prototype for a fully online version of the course.

Discussion

This study introduces a novel university-level course to provide young adult students comprehensive, evidence-based education on sexual and reproductive health from a public health perspective. The program leverages existing CSE efforts, enhancing them with academic rigor, inclusive content and digital inclusion. This approach, inclusive of diverse sexual orientations, content on pleasure and sexual violence prevention, aims to fill existing gaps in university curricula and also set a new standard in CSE. The project's innovative and multidisciplinary design offers a model for broader impact within a large public university system and beyond.

Knowledge, attitudes and practices of contraceptive methods among students in public and private high schools in Cameroon

The use of contraceptive methods is still a controversial subject in the societies of developing countries. This study aims to assess the knowledge, attitudes, and practices of contraceptive methods among students, aged 15 to 25 years, in public and private schools in the district of Bonaberi, Douala, Cameroon. This research was modeled on the pattern of descriptive study. The population in this study was composed of students (N = 1649) from the five public and private high schools of Bonaberi, Cameroon. The sample size of this study was 379 students. These data were collected in person by the researcher between 1 and 30, June 2022. The data collection tools are the student information form, the Knowledge and Practices of Contraceptive Methods Questionnaire, and the Contraceptive Attitude Scale (CAS). The data of this study were analyzed using descriptive statistics tests, Kruskal-Wallis Test, Pearson Chi-Square, Kolmogorov-Smirnoff, Student's T-Test, Mann-Whitney Test, and the One-way ANOVA. It was found that almost half (45.91 percent) of students were 19-22 years old, 59.1 percent of them were male, and almost half (49.3 percent) of them were sexually active. Currently, the male condom is the most commonly used and known method of contraception among students. It was determined that students take an average of 3.406 points from the total score of CAS. This result indicated a positive attitude toward contraceptive methods. There were no statistically significant differences in contraceptive attitudes according to gender, religion, or sexual activity. There was a statistically significant difference in contraceptive attitudes according to marital status and age. It is recommended to provide family planning counseling services in these schools in order to increase the use of effective methods and provide students with a reliable source of information on contraceptive methods.

Trends in prevalence and factors associated with unintended pregnancies in Zambia (2001-2018)

BACKGROUND

Unintended pregnancies can pose significant public health concerns for both maternal and child health because of their associated risks and implications. Experience of unintended pregnancies may lead to delay in seeking antenatal care, thus leading to increased risk of complications during pregnancy and childbirth. Globally, the prevalence of unintended pregnancies has declined. However, the problem remains acute in sub-Saharan Africa. This study was conducted to examine the factors associated with an experience of unintended pregnancy among women of reproductive ages in Zambia.

METHODS

This study used secondary data from the Zambia Demographic and Health Surveys (ZDHSs) which were conducted between 2001 and 2018. A pooled weighted sample of 4,090 pregnant women of reproductive age 15-49 years at the time of the survey was included in the analysis. Multivariable binary logistic regression model was employed to examine the association between independent correlates and experience of unintended pregnancy. All statistical analyses were conducted using Stata software.

RESULTS

Findings show that the proportion of women of reproductive age who experienced unintended pregnancy in Zambia declined from 50.4% (95% CI: 47.1, 53.8) in 2001 to 45.2% (95% CI: 40.5, 49.9) in 2018. The decline in the prevalence of unintended pregnancy is more pronounced among women age groups 25-29 years and 30-34 years. Increasing age was associated with an increased risk of experiencing unintended pregnancies. On the other hand, women who were living in rural areas (aOR = 0.76; 95% CI: 0.58, 1.00) and those with tertiary education (aOR = 0.46; 95% CI: 0.26, 0.80) were less likely to experience an unintended pregnancy. Women who desired a large family (aOR = 0.45; 95% CI: 0.24, 0.85) and those who watched television (aOR = 0.75; 95% CI: 0.59, 0.94) had lower odds of experiencing unintended pregnancies.

CONCLUSIONS

The study has established that the prevalence of unintended pregnancy is still high in Zambia. Women's age, place of residence, level of education, desired family size and exposure to media were associated with the risk of experiencing an unintended pregnancy. Enhancing access to family planning services and commodities targeting women with low education levels will be key to further reduce unintended pregnancies.

Need for Sexual, Reproductive, and Mental Health Promotion Among Diverse College Students in a COVID-19 Era

In 2020, the COVID-19 pandemic forced unprecedented disruptions in higher education operations. While the adverse mental health effects experienced by college students due to these changes are well documented, less is known about the impact on their sexual and reproductive health (SRH), and the reciprocal relationships between SRH and mental health among adolescents and emerging adults. This position paper reviews existing literature on the effects of the COVID-19 pandemic on SRH, sexual violence, unintended pregnancy, sexually transmitted illness and human immunodeficiency virus rates and highlights issues specific to college-aged males, females, racial/ethnic and sexual minorities, and individuals with disabilities. The need to conceptualize SRH as an integral component of normal development, overall health, and well-being in the context of COVID-19 is discussed. The need to prioritize the design and implementation of developmentally appropriate, evidence-based SRH interventions specifically targeting college students is identified. Furthermore, an intergenerational approach to SRH that includes parents/caregivers and/or college faculty and staff (e.g., coaches, trainers) could facilitate comprehensive SRH prevention programming that enhances sexual violence prevention training programs currently mandated by many colleges. Policies and programs designed to mitigate adverse pandemic-related exacerbations in negative SRH outcomes are urgently needed and should be included in mainstream clinical psychology, not only focused on preventing unwanted outcomes but also in promoting rewarding interpersonal relationships and overall well-being. Recommendations for clinical psychologists and mental health researchers are made.

A Meta-Analysis of the Effects of Comprehensive Sexuality Education Programs on Children and Adolescents

Childhood and adolescence are crucial periods for developing one's awareness of sexuality. Comprehensive Sexuality Education (CSE) during these stages is essential for overall growth, fostering healthy self-concepts, and addressing diverse sexual issues among children and adolescents globally. A meta-analysis was conducted to analyze the effectiveness of CSE programs. A literature search was performed on EMBASE, PubMed, CINAHL, Cochrane Library, and PsycInfo for studies published before 14 June 2023, and based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We used the Comprehensive Meta-Analysis (CMA, V4) software version 4.0 for the analysis and interpreted the effect sizes according to Cohen's definition. Between 2011 and 2020, 21 studies on CSE were published, with the United States having the most publications (17). Of the 34 studies reviewed, 20 were randomized controlled trials. The primary population for CSE was middle/high school students (15), with the most frequent age range being 10-19 years (26). The overall effect size of CSE was significant (effect size = 1.31, p < 0.001), with cognition (effect size = 5.76, p < 0.001) being the most significant. CSE is an effective educational tool for children and adolescents with a significant impact on variables such as cognition and abstinence. It should be incremental from childhood and adolescence to adulthood.

Reassessing Preterm Birth Prevention After the Withdrawal of 17-α Hydroxyprogesterone Caproate

The U.S. Food and Drug Administration has recently withdrawn approval for 17-α hydroxyprogesterone caproate for prevention of recurrent preterm birth, and recent studies have called into question benefits of the pessary in the setting of a short cervix. Obstetric health care professionals are once again left with limited remaining options for preterm birth prevention. This narrative review summarizes the best current evidence on the use of vaginal progesterone, low-dose aspirin, and cerclage for the prevention of preterm birth; attempts to distill possible lessons learned from studies of progesterone and pessary, as well as their implementation into practice; and highlights areas where inroads into preterm birth prevention may be possible outside of the progesterone-aspirin-cerclage paradigm.

The long-term effects of reproductive health education among primary and secondary school students: a longitudinal quasi-experimental study in rural Tanzania

BACKGROUND

Adolescent pregnancy remains a major global health issue, increasing the risk of complications during pregnancy and childbirth in mothers and babies. In Tanzania, adolescent pregnancy threatens girls' education and makes it difficult for them to obtain a proper job; hence, the majority fall into poverty. Previous studies have developed and conducted reproductive health education for adolescent students; however, they evaluated only the effect immediately after education. Therefore, this study investigated the effects of reproductive health education on attitudes and behaviors toward reproductive health among adolescent girls and boys one year after the intervention in rural Tanzania.

METHODS

A longitudinal quasi-experimental study was conducted with 3295 primary and secondary students (2123 in the intervention group, 1172 in the control group) from three purposefully selected wards in Korogwe District. In the intervention group, the students received reproductive health education. We used paper-based questionnaires to evaluate the effect of the adolescent education program on attitudes and behaviors toward reproductive health education. To analyze the association between the intervention and each outcome, mixed-effect multiple regression analyses was conducted.

RESULTS

The mean age, primary school proportion, and female proportion of the intervention and the control group was 13.05 (standard deviation (SD) 1.59), 14.14 (SD 1.7), 77.9% and 34.3%, and 54.2% and 52.6%, respectively. There was no statistically significant effect of reproductive health education on adolescent health attitudes and behaviors in the multiple regression analyses (coefficient: - 0.24 (95% confidence interval (CI): - 0.98 to 0.50), coefficient: 0.01 (95%CI: - 0.42 to 0.43)).

CONCLUSION

A statistically significant effect of reproductive health education on adolescent health attitudes and behaviors was not found. An effective reproductive health education intervention to improve the attitude and behaviors of reproductive health among Tanzania adolescents in the long term remain to be determined, particularly in real-world settings.

Classroom Voices: Youth Perspectives to Direct School-based Sexual Health Education

Sexual health education is a well-known, evidence-based intervention that can improve adolescent health outcomes, increase protective health behaviours, and decrease risky health behaviours. Providing sexual health education in school settings offers opportunities for discussion of critical health topics and can improve the school environment for all students. However, not all sexual health education is taught equitably across classroom environments. As part of a mixed-methods study to describe school-based sexual health education, we conducted focus groups and interviews with recently graduated high school students in New Mexico, a geographically and ethnically diverse state in the US Southwest. Thirty-one young people shared their experiences, explored the sexual health education content they had been taught, and offered recommendations to improve sexual health education. Three key themes were developed: young people wanted and needed sexual health education taught in school settings; the sexual health education currently taught in school is not helpful and sometimes harmful; and the individuals who teach sexual health education are critically important. These findings can inform and support school staff and administrators addressing barriers to school-based sexual health education delivery, particularly in schools within marginalised communities with limited resources. The results support including youth as stakeholders in the planning, delivery and evaluation of school-based sexual health education; and the development of sexual health education training for teachers, with the goal of improving health outcomes for all youth populations.

Effects of Sexuality Education on Sexual Knowledge, Sexual Attitudes, and Sexual Behaviors of Youths in China: A Cluster-Randomized Controlled Trial

PURPOSE

There is a lack of trained educators and age-appropriate teaching materials for sex education in China. This study aims to assess the effects of an internet-based sexuality education programme on sexual knowledge, attitudes, and behaviors among adolescents in China.

METHODS

We undertook a multicentre, cluster-randomized controlled trial in 29 vocational high schools in Guangdong and Yunnan, China. Students in the intervention group received weekly sexuality education delivered over two months based on a sexuality education package named "You and Me". A questionnaire was completed at baseline by all students, after receiving a sexuality education by the intervention group, and once a year after receiving sexuality education by the intervention group or at a similar time point by the control group.

RESULTS

Between October 2018 and December 2019, 3,151 participants from 29 schools/clusters were recruited, from which 1,760 students were randomly assigned to receive an eight-session internet-based sexuality education package. Significant improvements were observed for both sexual knowledge and sexual attitudes immediately after the intervention and one year after the intervention. However, no significant effects were observed for sexual behaviors.

DISCUSSION

The internet-based sexuality education package was found to positively affect the sexual knowledge and sexual attitudes among adolescents, providing a potential solution to the lack of trained educators and teaching resources for implementing country-wide sexuality education in China. However, further research is still needed to determine the effects of sexuality education packages on sexual behaviors.

Relationship of Age at Menarche, Coitarche and First Gestation: A Retrospective Cohort Analysis

Introduction

Teenage pregnancy is defined as a pregnancy occurring between ages 10 and 19 (Loredo-Abdlá et al., 2017; Belitzky, 1985; Kaplanoglu et al., 2015), and is associated with increased morbidity and mortality for both mother and child. Several factors have been identified with increased risk of a teenage pregnancy, including incomplete sexual education awareness and increased exposure at a young age. In addition, an earlier onset of sexual intercourse, or coitarche, has been linked to a higher risk of teenage pregnancy. Early menarche, defined as first menstruation before the age of 12 has been previously identified as a risk factor for an earlier coitarche, possibly linking an early menarche with a higher incidence of teenage pregnancy. This study aims to compare and determine the relationship between the incidence of teenage pregnancy with early menarche and coitarche in a low income setting.

Design Setting Participants Interventions Main Outcome Measures

A cross sectional review of electronic records of women admitted for delivery in a second level center in northeastern Mexico, being a low-income setting, where 814 teenage and 1474 adult mothers were included.

Results

Primigravid teenagers had earlier menarche and coitarche than adult counterparts and opted for postpartum contraception more frequently. Linear regression analysis revealed significant unadjusted beta coefficients between age at first pregnancy and coitarche (0.839) and menarche (0.362). Menarche and coitarche had a significant linear regression association of 0.395.

Conclusion

We found amongst primigravid patients that teenagers had earlier menarche and coitarche than adults, which in turn correlated to their age at their first pregnancy.

Predictors of Unintended Pregnancy Among Adolescent Girls During the Second Wave of COVID-19 Pandemic in Oyam District in Northern Uganda

Background

In Uganda, unintended pregnancies are responsible for one in three births with detrimental consequences, a situation that worsened during COVID-19. Thus, the present examined unplanned pregnancy and its associated risks in Oyam district, northern Uganda during the COVID-19 epidemic.

Methods and Methods

This study employed a cross-sectional study among adolescent girls aged 15-19 years who had a pregnancy during the second phase of COVID-19 in Oyam district, northern Uganda in November 2022. A consecutive method was employed to recruit the participants attending health facilities. A structured questionnaire was utilized to collect data. For data analysis, both bivariate and multivariable regression methods with adjusted odds ratio and 95% CI were used. A p-value of 0.05 was used to determine the significance level.

Results

Of the total respondents, 292 (69.5%) were aged between 18 and 19 years of age, 295 (70.2%) lived in rural areas, and 222 (52.9%) had no formal education. The results also show that 293 (69.8%) of the respondents had unintended pregnancies during COVID-19. The results indicate that participants who lacked knowledge of the ovulation period (AOR: 0.242; 95% CI: 0156-0376; P<0.001), sex education during COVID-19 (AOR: 0.563; 95% CI:: 0.365-0.869; P=0.024) and lacked the freedom to discuss family planning-related issues with family members during COVID-19 (AOR: 0.228; 95% CI: 0.138-0.376; P<0.001) were more likely to have an unintended pregnancy compared to their counterparts.

Conclusion

Our study shows that unwanted pregnancies among adolescent girls remain a public health issue in Oyam district with more than two-thirds of adolescents having unwanted pregnancies during the crisis of COVID-19. The major correlates of unwanted pregnancies among adolescent girls during COVID-19 pandemic were inadequate knowledge of the ovulation period, sex education, and lack of freedom to discuss family planning-related issues with family members. There is a need to prioritize interventions, especially in rural settings. Sex education to improve contraceptive use and delay sexual debut. In light of the possibility that social and cultural norms in the Oyam district prohibit parents and children from discussing sexual subjects, it is crucial to promote sexual health education through the mass media, including newspapers, television, radio, and social media.

Sex Ed in the Post-Roe World: Implications for Public Health Education

The overturning of Roe v. Wade and the increasing assaults on lesbian, gay, bisexual, transgender, queer (LGBTQ+) rights in legislatures across the country have put our sexual and reproductive health in peril. They are likely also bellwethers of more to come. While a full reckoning of the repercussions from these attacks will not be known for a long time, the field of public health must act now with a strong and cohesive plan to mitigate the harms, fight these threats to our well-being, and lead the way forward.

Emergency Contraception: Access and Challenges at Times of Uncertainty

BACKGROUND

The UN Commission on Life-Saving Commodities for Women's and Children's Health identified emergency contraceptive pills as 1 of the 13 essential underused, low-cost, and high-impact commodities that could save the lives of millions of women and children worldwide. In the US, 2 emergency contraceptive regimens are currently approved, and their most plausible mechanism of action involves delaying and/or inhibiting ovulation.

AREAS OF UNCERTAINTY

Abortion and contraception are recognized as essential components of reproductive health care. In the US, in the wake of the Dobbs v. Jackson Women's Health Organization Supreme Court decision on June 24, 2022, 26 states began to or are expected to severely restrict abortion. It is anticipated that these restrictions will increase the demand for emergency contraception (EC). Several obstacles to EC access have been described, and these include cost, hurdles to over-the-counter purchase, low awareness, myths about their mechanisms of action, widespread misinformation, and barriers that special populations face in accessing them. The politicization of EC is a major factor limiting access. Improving sex education and health literacy, along with eHealth literacy, are important initiatives to improve EC uptake and access.

THERAPEUTIC ADVANCES

A randomized noninferiority trial showed that the 52 mg levonorgestrel intrauterine device was noninferior to the copper intrauterine device when used as an EC method in the first 5 days after unprotected intercourse. This is a promising and highly effective emergency contraceptive option, particularly for overweight and obese patients, and a contraceptive option with a different bleeding profile than the copper intrauterine device.

CONCLUSIONS

EC represents an important facet of medicine and public health. The 2 medical regimens currently approved in the US are very effective, have virtually no medical contraindications, and novel formulations are actively being investigated to make them more convenient and effective for all patient populations. Barriers to accessing EC, including the widespread presence of contraception deserts, threaten to broaden and accentuate the already existing inequities and disparities in society, at a time when they have reached the dimensions of a public health crisis.
