The Nurses' Health Study

The Nurses' Health Study is a large, ongoing research project that began in 1976, involving thousands of female nurses in the United States. It aims to understand how lifestyle factors—such as diet, exercise, and smoking—affect health and the risk of chronic diseases like heart disease, cancer, and diabetes. By collecting detailed health and lifestyle data over many years, the study provides valuable insights into disease prevention and health promotion, benefiting public health knowledge.
