Abstract
Objective: To determine the prevalence of chronic venous insufficiency in the general population and its association with varicose veins. Data sources: MEDLINE search 1980–94 plus scanning of reference lists in articles obtained. Study selection: Studies on venous disease in subjects not attending health services. Data synthesis: A formal systematic review of metaanalysis was not carried out because of the heterogeneity of the few available studies. Skin changes were found to occur in over 3% of adults, more so in women than men. The prevalence was higher in subjects with varicose veins and depended on the definition of skin changes and the severity of varicose veins. Approximately 0.3% of adults had an open varicose ulcer, and around 1% had an open or healed ulcer. Prevalence was higher in women and increased with age. Conclusions: The prevalence of chronic venous insufficiency was found to be common in the general population, but more studies of distribution and aetiology are required.
