ISILUNA: Global Citizen Science Impact on Menstrual Products on the Vaginal Microbiome

Sarah Leeber of the University of Antwerp in Belgium, with Marie Josiane Kenfack of the Center for Research on Emerging and Reemerging Diseases (CREMER) in Cameroon, will add DNA sequencing analysis of the vaginal microbiota as a component for a set of clinical trials of menstrual hygiene products in Belgium, Switzerland, Cameroon, and Peru. The longitudinal trials compare use of different menstrual products, with participants using either the same product over time or different products in sequence, including pads, tampons, cups, and underwear. Surveys and group discussions will be used to gather data on user perceptions of the products and how acquiring knowledge of the microbiome may influence attitudes and practices. Shotgun metagenomic sequencing from self-collected samples will reveal changes in the vaginal microbiota associated with different products. Together, this data will provide a more comprehensive understanding of both the biological and behavioral dimensions of menstrual product use.
