An estimated two billion people currently experience a menstrual cycle. There is recognition globally that unmet menstrual needs result in harms to women’s and girls’ physical and mental health, education, and gender equality.

Efforts are being made to support the implementation of evidence-based programs and policies aimed at improving menstrual health and hygiene. The stigma and silence surrounding menstruation have contributed to limited evidence, making it challenging to understand menstrual needs and develop effective support strategies. Additionally, the data and evidence required to make a strong case for investing in menstrual health and hygiene remain insufficient.

This fellowship is addressing significant evidence gaps.

One focus is advancing the measurement of menstrual health and hygiene needs. A comprehensive tool, the Menstrual Practice Needs Scale (MPNS), was developed in 2020 to assess these needs. This tool allows respondents to report whether they had adequate resources during their last menstrual period, such as sufficient materials for blood absorption or appropriate spaces for changing and washing. Initially developed in Uganda, this measure is now being applied in various countries globally. Through the fellowship, the performance of the measure is being tested across different populations, with plans to develop a shorter version to facilitate quicker administration in research and practice. Additionally, missing evidence is being provided by testing the impact of unmet menstrual health and hygiene needs during adolescence on broader health and educational outcomes.

By following a group of adolescent girls over time, changes in their menstrual needs are being captured to inform effective interventions. This longitudinal approach will allow for an assessment of how their menstrual health and hygiene experiences affect their psychological well-being and schooling.
