Nurses’ Health Study – The Nurses’ Health Study, established in 1976 by Dr. Frank Speizer and the Nurses’ Health Study II, established in 1989 by Dr. Walter Willett, are among the largest prospective investigations into the risk factors for major chronic diseases in women. The studies have grown to include a team of clinicians, epidemiologists and statisticians at the Channing Laboratory along with collaborating investigators and consultants in the surrounding medical community of the Harvard Medical School, the Harvard T.H. Chan School of Public Health, Brigham and Women’s Hospital, Dana Farber Cancer Institute, Boston Children’s Hospital, and Beth Israel Hospital.
The Health Professionals Follow-Up Study – The Health Professionals Follow-Up Study (HPFS) began in 1986. The purpose of the study is to evaluate a series of hypotheses about men’s health relating nutritional factors to the incidence of serious illnesses, such as cancer, heart disease, and other vascular diseases. This all-male study is designed to complement the all-female Nurses’ Health Study, which examines similar hypotheses.
