Spanish National Health Survey

Initiatives -
The Spanish National Health Survey (ENSE) is a study obtained through household interviews where health information is collected on the entire population. The objectives of the ENSE are: 1. To measure the characteristics and distribution of the morbidity perceived by the Spanish population and the characteristics and distribution of certain behaviors and habits related to health. 2. Similarly, the survey explores the use of health services by the population. 3. Finally, it relates all these characteristics to each other and to personal, demographic and territorial variables. The first ENSE was conducted in 1987, then with modifications in 1993, 1995, 1997 , 2001, and 2003.
