DESCRIPTION: The TREMIN Research Program on Women's Health is one of the world's oldest ongoing research programs dedicated to studying menstration and women's health. Initiated in 1934 by Dr. Alan E. Treloar at the University of Minnesota, this unique intergenerational study was established to document menstrual cycle variations. It has followed several thousand women throughout their reproductive lives. TREMIN participants provide a wide variety of information related to menstruation and health by completing a annual health survey and daily menstrual diary. Initially, 2,350 University of Minnesota women volunteered to participate in the study in the 1930s. A second group of 1,600 women was enrolled between 1961-1963. In 1965, a panel of 1,000 native Alaskan women was invited to participate in the program. Women in the study range from their teens to mid-nineties and represent fifty states and twenty-five foreign countries.
