The POWER Study (Project for an Ontario Women's Health Evidence-based Report) is producing a two-volume Women's Health Report to serve as an evidence-based tool for policy makers, providers, and consumers in their efforts to improve health and reduce health inequities among Ontario women. POWER has just released the Burden of Illness which reports on the Burden of Illness (overall health and well-being) experienced by Ontarians, and how it differs by sex, socioeconomic status, ethnicity and geography. By painting a picture of health inequities in the province, opportunities for improvement are identified and objective evidence is presented to inform priority setting and to provide a baseline from which to measure progress. Also available are: Chapter 1, Introduction to the POWER Study and Chapter 2, The POWER Study Framework. To download, visit the website.
