Nurses' Health Study

The Nurses' Health Study (NHS) is a series of long-term epidemiological studies that examine the effects of various health factors on the medical well-being of registered nurses. The study is one of the largest and longest-running investigations into women's health.

Pronunciation

Nurses' Health Study: /ˈnɜːrsɪz hɛlθ stʌdi/

Etymology

The term "Nurses' Health Study" is derived from the profession of the study's participants (nurses) and the focus of the investigation (health study).

History

The Nurses' Health Study was established in 1976 by the Harvard T.H. Chan School of Public Health. The study initially recruited 121,700 registered nurses aged between 30 and 55 from 11 states in the United States. The study has since expanded to include two additional cohorts: the Nurses' Health Study II (NHS II) and the Nurses' Health Study 3 (NHS 3).

Methodology

Participants in the Nurses' Health Study are asked to complete a questionnaire every two years. The questionnaire collects information on various health factors, including diet, physical activity, smoking, and medical history. The data collected is then used to identify and study relationships between these health factors and various diseases.

Findings

The Nurses' Health Study has contributed to a wide range of discoveries in women's health. Some of the key findings include the link between diet and heart disease, the impact of physical activity on health, and the risks associated with hormone replacement therapy.
