Historical Risk Factors for Stroke: A Case Control Study

Abstract
The aim of this study was to determine the risk factors for admission to hospital with stroke by means of a case-control study recruiting age- and sex-matched controls from the local community. Four hundred pairs of patients and controls were recruited. Of historical factors, preceding cerebrovascular disease contributed the greatest odds of stroke (odds ratio 9.8). Taking prescribed medicines (odds ratio 2.6), regular snoring (odds ratio 3.2), smoking (odds ratio 1.7) and some factors in the family history were also significant risk factors.
