About HPFS:

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. The HPFS is sponsored by the Harvard School of Public Health and is funded by the National Cancer Institute. Learn More About HPFS »
