Women's Health Initiative Extension

The study started in 1993 to evaluate health outcomes in aging postmenopausal women and to identify factors associated with healthy aging. Between 1993 and 1998, more than 161,000 women between 50 and 79 years of age joined the WHI. Beginning in October 2004, participants were consented for sequential 5-year WHI Extension Studies (ES). The research team continues to collect self-reported as well as medical record adjudicated health and mortality data. A team of junior investigators are engaged with data analysis in an effort to advance the dissemination of WHI research findings. Arizona research team members have published over 45 manuscripts in the past 8 years using this well-characterized and robust phenotypic information.
