The European Health Survey 2009 (EES09) conducted by the National Statistics Institute and the Ministry of Health, Social Services and Equality, is a five-yearly research aimed at households, which collects health-related information on population resident in Spain with ages of 16 and over through a common European questionnaire. This information allows the planning and evaluation of interventions in health matters, both European and national.
The questionnaire consists of 4 modules: European social-demographic module (household and individual), European module on health status, European health care module and European module on health determinants.
