About AiMHI
Our Mission
Architecture for Menstrual Health Indicators (AiMHI) is a collaborative project that generates, fosters, and translates rigorous evidence to inform investment and action for improving menstrual health.
What AiMHI is doing
An estimated 2.1 billion people menstruate around the world, yet menstrual health (MH) has been overlooked as an essential driver of gender equity, health, education, and economic outcomes. Menstruation was not explicitly mentioned in the Sustainable Development Goals (SDGs) and rarely features in national surveys, government policy, or expenditure.
Building on the recognition achieved through grassroots efforts and evidence to date, the next few years present a critical window to establish menstrual health on the global agenda and to inform strategic approaches to policy and programming across countries.
Realizing this vision requires addressing several key evidence gaps. First, an ongoing gender data gap makes MH needs invisible and limits the ability to track progress. Second, we lack rigorous, evidence-based estimates of the impacts and costs of poor MH. Finally, advocacy and national and global initiatives have failed to harness data and evidence in decision-making, resulting in efforts that may not best serve the needs of adolescent girls and women.
To address these gaps, AiMHI focuses on three priority areas:
- Ensure inclusive, rigorous, nationally representative menstrual health data, including for young adolescents
- Provide evidence on the causal links between menstrual health and education, health and economic outcomes
- Promote quality evidence and its use to inform investment, policy and practice
Together, these efforts aim to strengthen the evidence base for menstrual health and ensure that data and research are translated into action.
Who We Are
This effort began as an informal collaboration among researchers and practitioners who had each spent years working to strengthen menstrual health evidence and programs, building on momentum from earlier efforts such as MHM in Ten, a ten-year agenda for menstrual health in schools (2014-2024). As an expanding group of menstrual health colleagues compared approaches and identified gaps, a shared vision emerged: the need for a standardized, evidence‑based set of priority indicators to support national and global monitoring for menstrual health.
What started as a voluntary, collective undertaking driven by shared commitment and passion for menstrual health gradually evolved into a formal initiative. Building on subsequent work with a growing number of national and global partners to develop and promote priority indicators for menstrual health, AiMHI is now established as a collaborative project that aims to generate, foster and translate rigorous and large-scale evidence to inform investment and action for improving menstrual health.
