The Society for Women's Health Research (SWHR) is a national non-profit organization based in Washington D.C. SWHR is the thought leader in research on biological differences in disease and is dedicated to transforming women's health through science, advocacy, and education. Founded in 1990 by Florence Haseltine, PhD, MD, SWHR aims to bring national attention to the need for the appropriate inclusion of women and minorities in major medical research studies and the need for more information about diseases and conditions affecting women exclusively, predominantly, or differently than men. It also promotes the analysis of research data for sex and ethnic differences; and informs women, healthcare providers, and policy makers about contemporary women's health issues through , briefings, conferences, and special events. As a result of SWHR's work, women and minorities are now included in medical research and clinical trials; scientists are researching the ways in which health conditions and diseases affect men and women differently and why. Through SWHR's use of evidence-based research and multi-pronged policy and public education efforts, as well as the involvement of health care providers and policy makers dedicated to improving women's health, sex differences is now a national priority.
