About us

The Nurses’ Health Studies are among the largest and longest-running investigations of factors that influence health and wellness. Started in 1976 and expanded in 1989, the information provided by 238,000 dedicated nurse-participants has led to many new insights on health and disease. While the prevention of cancer is still a primary focus, the study has also produced landmark data on cardiovascular disease, diabetes and many other conditions. Most important, these studies have shown that diet, physical activity and other lifestyle factors can promote better health.
