[BDSP. Notice produite par INIST 7XtR0xvh. Diffusion soumise à autorisation]. Study objective-High blood pressure is a variable related to several chronic conditions whose repeated measurement in large cohort studies is often not feasible having to rely on the self reporting of the subjects. The aim of the study is to validate such self diagnosis in a sample of members from the Spanish EPIC cohort study. Design-Comparison of high blood pressure self diagnosis with the information provided by the personal medical record drawn from the primary health centre of reference for such population. Setting-A small town near the EPIC-Murcia centre, one of five Spanish EPIC centres located in the south east, where inclusion in the cohort was offered to the general population. Participants-The agreement between self reported high blood pressure status and data from medical records was measured in a representative sample of men and women (n=248) aged 30-69 years. Medical records were studied for a diagnosis of high blood pressure, an anti-hypertensive pharmacological treatment or subject's inclusion in a hypertension control programme run in the medical centre only for hypertensive people (definite high blood pressure cases). As well, in the absence of such a diagnosis, medical annotations of systolic or diastolic high blood pressure>= 140190 mm Hg (possible high blood pressure cases) were considered. Sensitivity, specificity, positive and negative predictive values and K scores were calculated for all, definite and possible high blood pressure cases. (...)
