Abstract

A few international studies suggest an inverse association of the intake of fat with risk of ischemic stroke. On the contrary of coronary heart disease, only 10% a 15% of ischemic strokes are associated to large vessels atherosclerosis. This suggests different mechanisms for these two pathologies. So, we design a study whose aim is to quantify the ischemic stroke risk associated to dietary fat. A case-control study, that included two hundred ninety seven individuals of both sexes, hospitalized in the S. João Hospital in Oporto, with a first episode of ischemic stroke. Six hundred and seventy one controls of both sexes were also evaluated, selected by random digit dialing.

The information was obtained by a structured questionnaire, by interview that included socio-demographic, medical and behavioural aspects (physical activity, tobacco use, food habits). Food intake in the past year was evaluated by a validated, semi-quantitative food frequency questionnaire. Logistic regression was used to evaluate the relative ris...Continue Reading
