Secondary Data Analysis (SDA) Seminar Series - Women's Health Initiative

The Women’s Health Initiative (WHI) is an ongoing national health study aimed at identifying strategies for the prevention and control of major causes of mortality among postmenopausal women in the United States. The WHI started recruiting participants in 1993 and follow-up continues to this day in extension and ancillary studies. The investigator data collected during WHI follow-up are an invaluable resource for epidemiological and clinical researchers both due to its large sample size (161,808 women) and diversity (data include diet, medical history, physical measurements, and psychosocial measurements). The purpose of this seminar is to introduce investigators to the WHI data sets, summarize their strengths and limitations, and discuss the process for accessing them.
