Managing menstruation effectively and with dignity can be challenging for girls and women in low and middle-income countries. Currently there is limited research on menstrual hygiene management (MHM) in the Pacific region. This report presents findings from research that was undertaken in Papua New Guinea (PNG) in March 2017. The study is part of a larger piece of work that includes Fiji and Solomon Islands, and is funded through the Australian Government, Department of Foreign Affairs and Trade (DFAT). The research focuses on menstruation and how it is managed by women and adolescent girls in PNG. The purpose of the study is to explore the challenges experienced by women and girls in managing their menstruation, and whether these challenges make it hard for them to equally participate in school and work and engage with their communities.
