WHI, Women’s Health Initiative
Initiator and Sponsor
National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH)
A major piece of Berman Center activity since 1992, the Women’s Health Initiative (WHI) was one of the first large, multi-site, long-term studies of women’s health. A total of 161,861 women have been participating throughout the U.S. Participants were randomized to different treatment arms, including dietary modification, hormone replacement, calcium and vitamin D supplementation. Their health status has been followed for more than 12 years, paying particular attention to the major causes of death and health problems in women: cancer, heart disease, and broken bones.
