Effect of family history on the risk of varicose veins is affected by differential misclassification.

Objective: We assessed differential misclassification in self-reported family history of varicose veins by comparing consistency of subject's own varicose vein status and the consistency of information on varicose veins in family members.

Study Design And Setting: A population-based cohort study of 4,903 middle-aged residents of the city of Tampere, Finland. A questionnaire was used at entry and at the end of the 5-year follow-up.

Effect of family history on the incidence of varicose veins: a population-based follow-up study in Finland.

In the literature, the estimates of high risk of family history for varicose veins are based on prevalence rates from cross-sectional studies. The purpose of this study was to compare such prevalence rates with incidence rates from our longitudinal follow-up study to find out whether there is a difference due to the methodology. A validated questionnaire was used in 3 middle-aged cohorts (n = 6874) in Tampere, Finland.

Persons with varicose veins have a high subsequent incidence of arterial disease: a population-based study in Tampere, Finland.

The aim of this population research was to find out the risk of arterial disease (defined as angina pectoris, myocardial infarction, peripheral occlusive arterial disease, and cerebrovascular disease) and hypertension in persons with varicose veins. A 5-year follow-up study was conducted in Tampere, Finland. A validated questionnaire was used in 3 middle-aged cohorts (40, 50, and 60 year olds) in a general population of 6,874.
