The purpose of this Review is to provide evidence for why gender equality in science, medicine, and global health matters for health and health-related outcomes. We present a high-level synthesis of global gender data, summarise progress towards gender equality in science, medicine, and global health, review the evidence for why gender equality in these fields matters in terms of health and social outcomes, and reflect on strategies to promote change. Notwithstanding the evolving landscape of global gender data, the overall pattern of gender equality for women in science, medicine, and global health is one of mixed gains and persistent challenges. Gender equality in science, medicine, and global health has the potential to lead to substantial health, social, and economic gains. Positioned within an evolving landscape of gender activism and evidence, our Review highlights missed and future opportunities, as well as the need to draw upon contemporary social movements to advance the field.

School-based comprehensive sexuality education (CSE) can help adolescents achieve their full potential and realize their sexual and reproductive health and rights. This is particularly pressing in low- and middle-income countries (LMICs), where high rates of unintended pregnancy and STIs among adolescents can limit countries’ ability to capitalize on the demographic dividend. While many LMICs have developed CSE curricula, their full implementation is often hindered by challenges around program planning and roll-out at the national and local level. A better understanding of these barriers, and similarities and differences across countries, can help devise strategies to improve implementation; yet few studies have examined these barriers. This paper analyzes the challenges to the implementation of national CSE curricula in four LMICs: Ghana, Kenya, Peru and Guatemala. It presents qualitative findings from in-depth interviews with central and local government officials, civil society representatives, and community level stakeholders ranging from religious leaders to youth representatives. Qualitative findings are complemented by quantitative results from surveys of principals, teachers who teach CSE topics, and students aged 15–17 in a representative sample of 60–80 secondary schools distributed across three regions in each country, for a total of around 3000 students per country. Challenges encountered were strikingly similar across countries. Program planning-related challenges included insufficient and piecemeal funding for CSE; lack of coordination of the various efforts by central and local government, NGOs and development partners; and inadequate systems for monitoring and evaluating teachers and students on CSE. Curriculum implementation-related challenges included inadequate weight given to CSE when integrated into other subjects, insufficient adaptation of the curriculum to local contexts, and limited stakeholder participation in curriculum development. While challenges were similar across countries, the strategies used to overcome them were different, and offer useful lessons to improve implementation for these and other low- and middle-income countries facing similar challenges.

The successful implementation of comprehensive sexuality education (CSE) programmes in schools depends on the development and implementation of strong policy in support of CSE. This paper offers a comparative analysis of the policy environment governing school-based CSE in four low-and middle-income countries at different stages of programme implementation: Ghana, Peru, Kenya and Guatemala. Based on an analysis of current policy and legal frameworks, key informant interviews and recent regional reviews, the analysis focuses on seven policy-related levers that contribute to successful school-based sexuality education programmes. The levers cover policy development trends; current policy and legal frameworks for sexuality education; international commitments affecting CSE policies; the various actors involved in shaping CSE; and the partnerships and coalitions of actors that influence CSE policy. Our analysis shows that all four countries benefit from a policy environment that, if properly leveraged, could lead to a stronger implementation of CSE in schools. However, each faces several key challenges that must be addressed to ensure the health and wellbeing of their young people. Latin American and African countries show notable differences in the development and evolution of their CSE policy environments, providing valuable insights for programme development and implementation. ARTICLE HISTORY

Measuring the quality of sexuality education implementation at the school level in low-and middleincome countries,

Background: In the Peruvian Amazon, historical events of colonization and political marginalization intersect with identities of ethnicity, class and geography in the construction of gender and health inequities. Gender-based inequalities can manifest in poor health outcomes via discriminatory practices, healthcare system imbalances, inequities in health research, and differential exposures and vulnerabilities to diseases. Structural violence is a comprehensive framework to explain the mechanisms by which social forces such as poverty, racism and gender inequity become embodied as individual experiences and health outcomes, and thus may be a useful tool in structuring an intersectional analysis of gender and health inequities in Amazonian Peru. Objective: The aim of this paper is to explore the intersection of gender inequities with other social inequalities in the production of health and disease in Peru’s Amazon using a structural violence approach. Design: Exploratory qualitative research was performed in two Loreto settings – urban Iquitos and the rural Lower Napo River region – between March and November 2015. This included participant observation with prolonged stays in the community, 46 semi-structured individual interviews and three group discussions. Thematic analysis was performed to identify emerging themes related to gender inequalities in health and healthcare and how these intersect with layered social disadvantages in the reproduction of health and illness. We employed a structural violence approach to construct an intersectional analysis of gender and health inequities in Amazonian Peru. Results: Our findings were arranged into five interrelated domains within a gender, structural violence and health model: gender as a symbolic institution, systemic gender-based violence, interpersonal violence, the social determinants of health, and other health outcomes. Each domain represents one aspect of the complex associations between gender, gender inequity and health. Through this model, we were able to explore: gender, health and intersectionality; structural violence; and to highlight particular local gender and health dynamics. Intersecting influences of poverty, ethnicity, geography and gender served as significant barriers to healthcare in both rural and urban settings.
