Diferencias en estilos de vida y calidad de la información autorreferida según nivel de estudios: el proyecto SUN

Summary We assessed differences across educational levels in lifestyle to evaluate selection bias and quality of self-reported information in the baseline data of participants in a prospective cohort. A baseline cross-sectional analysis of the data of participants (n=15,404) in the SUN cohort was conducted. Among participants with higher (university) educational levels, body mass index and prevalence of high blood cholesterol were signifi cantly lower than in participants with lower educational level, whereas alcohol consumption was slightly higher. In another 37 lifestyle/ nutrition variables compared, there were no signifi cant differences. On other hand, missing data were more frequently found among participants with lower education (adjusted odds ratio: 1.99; 95% CI; 1.68-2.37). With only 3 exceptions, no signifi cant differences in lifestyle or food habits were found between educational levels. However, the quality of self-reported information was considerably greater among more highly educated participants.
