[Prevalence of mental disorders in the general population of Catalonia. Team of the Health Survey of Catalonia].
OBJECTIVE
The objective of the study is to estimate the prevalence of mental disorders in the general population of Catalonia.


METHODS
Data comes from the Health Interview Survey of Catalonia (Enquesta de Salut de Catalunya, ESCA) and from an epidemiological study of Tres Cantos (Madrid). The General Health Questionnaire (GHQ-12) was administered to all the individuals older than 14 years (n: 12,455). The prevalence was estimated according to the GHQ score obtained and its correspondence to the probabilities score of the Madrid study. This study determined the probability of being a psychiatric case in a logistic regression using the Present State Examination (PSE) as gold standard. Morbidity Comparative Index (MCI) was used to compare the prevalences between health regions. The population of reference was the population of Catalonia.


RESULTS
The 17.42% (CI 95%: 17.02-17.82) of the population of Catalonia older than 14 years suffered a probable mental disorder, the 18.66% (CI 95%: 18.07-19.25) in women and the 15.77% (CI 95%: 15.26-16.28) in men. The prevalence was higher in women with regard to men in all age groups. The MCI was lower in the Health Regions of Lleida and Girona and it was higher in the Health Regions of Tarragona and Tortosa, both in men and women.


CONCLUSIONS
The figures are at intermediate level with respect others Spanish and Anglo-Saxon published studies based on population data and lower than the obtained for primary care users in Spain and in other international settings.
