The Nurses Health Study is a series of prospective studies that examine epidemiology and the long term effects of nutrition, hormones, environment, and nurses' work life on health and disease development. The studies have been among the largest investigations into risk factors for major chronic diseases ever conducted. The Nurses' Health Studies have led to many insights on health and well being, including cancer prevention, cardiovascular disease, and type 2 diabetes.

Beginning in the 1960s, oral contraceptives were used by the public in the U. S. and U. K. Policies such as the 2008 Physical Activity Guidelines for Americans and the Dietary Guidelines of the Food and Drug Administration regarding trans fat related to the findings of these studies. Influential figures in the Nurses' Health Study have published advice for women based on their findings. For example, the book Healthy Women and Healthy Lives was written by Hankson, Colditz, Manson, and Speizer to reflect results of the study. This work makes explicit suggestions for a healthy lifestyle based on the study.

This study was referenced in popular news by many sources. The term "Nurses' Health Study" has been stated in over three hundred articles of the New York Times and The Washington Post alone. These articles discussed the findings of the study, such as one titled Women, Alcohol and the Search for Certainty. Published as early as 1988, this Washington Post article discussed the effect of the Nurses' Health Study on the relationship between women and alcohol, citing the former as a factor which affects a woman's risk for CVD and strokes. The 2004 article discusses the research of the study and resulting understanding of general health in older populations. In this way, the findings and magnitude of the Nurses Health Study reached the public throughout its history.

The Nurses' Health Study 1 contained populations representing nurses of the time, but did not reflect great diversity. The participants had a slightly higher income than the average of the time and a majority were white (97%). However, the Framingham Heart Study found the opposite result. This controversy caused a 10 year follow up by the Nurses' Health Study which again concluded that risks of CVD were lower in samples currently taking hormones. Findings from the study displayed a direct relationship between therapy and risk for heart disease, as opposed to the previously stated benefits. This finding largely opposed the published Nurses' Health Study conclusion.
