ES·ESC: Follow-up study of the Cornellà Health Survey

Background
Existe en España cohortes formadas con voluntarios, como son el proyecto MONICA sobre factores de riesgo cardiovascular, el estudio EPIC sobre dieta y cáncer o el estudio SUN sobre dieta y otros factores de riesgo. En nuestro país se han realizado diversas Encuestas de Salud de ámbito nacional, autonómico o local, pero no hay una tradición de estudios de seguimiento de la mortalidad y/o de la incidencia experimentada en estas muestras representativas de la población general, que fueron entrevistadas personalmente, y de las que se obtuvo información en relación no sólo a su estado de salud y estilos de vida sino también sobre comorbilidad y utilización de servicios sanitarios.

Main objective
The main project objective was to analyse the changes in tobacco, alcohol consumption and physical activity between 1994 (baseline interview) and 2002 (follow-up interview). Also, the project aimed to obtain information on other transversal health-related psychosocial factors (risk perception, locus of control, and social support) and investigate methodological aspects of the cohort studies.

Methodology
Design: Prospective cohort study of a representative sample of the general population. Scope of the study: general non-institutionalized population of Cornellà de Llobregat (Barcelona). Subjects of the study: 1,237 men and 1,263 women interviewed in 1994 in Cornellà in 1994. Procedures: follow-up of the cohort and obtaining new information about lifestyles and incidence of diseases via personal telephone interview in 2002. The follow-up questionnaire was developed based on the one used at the baseline interview. The questionnaire was validated during the piloting process on a convenience sample of respondents. The determinants related to lifestyle changes and relative risk of developing studied diseases were analysed using Cox models and logistic regression.

Duration
2002-2005.

Financial Support
Grant PI020261 (26,680.00 €, in three annual payments) of the Health Research Fund of the Institute of Health Carlos III (European Regional Development Fund, ERDF) and the contracts with Cornellà de Llobregat City Hall.
