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, were long-term epidemiological studies conducted on women's health. The study followed 121,700 female registered nurses since 1976 and 116,000 female nurses since 1989 to assess risk factors for cancer and cardiovascular disease. The studies are among the largest investigations into risk factors for major chronic diseases in women ever conducted. The studies include clinicians, epidemiologists, and statisticians at the Channing Laboratory. Participating organizations from the Massachusetts medical community include the Harvard Medical School, Harvard School of Public Health, and several Harvard-affiliated hospitals, including Brigham and Women's Hospital, Dana–Farber Cancer Institute, Children's Hospital Boston, and Beth Israel Deaconess Medical Center.

The study is recruiting a new cohort of 100,000 female licensed practical nurses (LPNs) and registered nurses (RNs) (or those studying to become one) aged 20-46 called the Nurses' Health Study 3 (NHS3). NHS3 is completely online, using social media for recruitment.

Famous quotes containing the words health and/or study:

    I would hope that parents and grown children could be friends. When a friend confides in you that she’s going to do something that you think is most inappropriate, foolhardy or even dangerous, wouldn’t you as a friend say so—in a calm, supportive way? Yet I have to be so careful what I say to my children. I have to walk on eggs to be sure I’m not hurting their feelings or interfering with their lives.
    —Anonymous Parent of Adult Children. Ourselves and Our Children, by Boston Women’s Health Book Collective, ch. 5 (1978)

    Hence a young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end aimed at is not knowledge but action.
    Aristotle (384–322 B.C.)
