The European Health Examination Survey (EHES) is an ongoing series of large-scale clinical epidemiological studies. It is a cooperative effort among multiple European nations, in concert with the European Union (EU), the European Economic Area (EEA) and the European Free Trade Area (EFTA). While actual data collection is carried out through the health ministries of each participating nation, the coordination of these efforts across borders is under the jurisdiction of the European Commission's Directorate-General for Health and Food Safety.
