Prevalence estimates vary based on population, selection criteria, disease definition, and imaging techniques. Generally, prevalence rates are higher in industrialised countries and in more developed regions.[4]Beebe-Dimmer JL, Pfeifer JR, Engle J, et al. The epidemiology of chronic venous insufficiency and varicose veins. Ann Epidemiol. 2005 Mar;15(3):175-84.

Prevalence of visible varicose veins in the Western population aged over 15 years is 10% to 15% in men and 20% to 25% in women.[5]Callam MJ. Epidemiology of varicose veins. Br J Surg. 1994 Feb;81(2):167-73.

Prevalence rates in the US are 15% (range from 7% to 40%) in men and 27.7% (25% to 32%) in women.[6]Fan CM. Epidemiology and pathophysiology of varicose veins. Techniques Vasc Intervent Radiol. 2003 Sep;6(3):108-10.

Visible varicose veins are more prevalent in Hispanic people (26.3%) and less prevalent in Asian people (18.7%).[7]Criqui MH, Jamosmos M, Fronek A, et al. Chronic venous disease in an ethnically diverse population. Am J Epidemiol. 2003 Sep 1;158(5):448-56.

The prevalence of varicose veins increases with age. In one study, 40-year-olds had a prevalence of 22%, 50-year-olds a prevalence of 35%, and 60-year-olds a prevalence of 41%.[8]Laurikka JO, Sisto T, Tarkka MR, et al. Risk indicators for varicose veins in forty- to sixty-year-olds in the Tampere Varicose Vein Study. World J Surg. 2002 Jun;26(6):648-51.

A genetic link has been suggested. The risk of varicose veins developing if both parents are affected is 90%; 62% risk if one parent is affected and female offspring; 25% risk if one parent is affected and male offspring; and if no parent is affected, the risk is 20%.[9]Cornu-Thenard A, Bovin P, Baud JM, et al. Importance of the familial factor in varicose veins. J Dermatol Surg Oncol. 1994 May;20(5):318-26.
