The goal of this research project was to provide up-to-date and comprehensive information on the status of MHH among school girls across Tanzania’s primary and secondary schools. The report provides an introduction to the topic and also presents the methods adopted to gather information on menstrual practices. Then the results of this research are provided. The report broadly highlights Tanzanian school girls’ knowledge, attitude and practices, sociocultural aspects surrounding menstruation and school water, sanitation and hygiene (SWASH) infrastructure and its management. How girls with disability negotiate their menstrual periods is specifically given prominent attention. After the discussion of the results, major conclusions of the study are drawn. Further, the researchers working on this report provide policy and practice recommendations for bettering menstrual health among school girls to the Tanzanian Government.
