Poor menstrual health can affect education, employment, physical health, mental health, and social participation, with impacts that accumulate across the life course. While there is growing recognition that menstrual health matters, there are still few reliable quantitative estimates of the extent to which menstrual health affects girls' lives over time.

AiMHI’s Menstrual Health Impact stream brings together data from prospective longitudinal studies with the goal of generating missing cross-country estimates on the impact of menstrual health on the lives of adolescent girls, and evidencing the hypothesized pathways from poor menstrual health to life outcomes.

This work aims to address critical evidence gaps by strengthening our understanding of the longer-term impacts of poor menstrual health. These gaps include the cost of inaction on menstrual health and the current deficits attributable to poor menstrual health, and this work can help identify where, when, and how interventions can have the greatest impact. By generating rigorous causal evidence, AiMHI aims to inform advocacy, guide strategic investment, and support the development of effective policies and interventions.
