Venous Insufficiency at Work

Chronic venous disease of the lower limbs is one of the most common conditions affecting humankind. It has been postulated that certain workplace conditions may be risk factors for venous insufficiency and varicose veins in particular. This paper examines the evidence for a link between occupation and the prevalence of venous disease. It also reviews recent French research carried out to estimate the prevalence of chronic venous insufficiency in a working population; work and nonwork risk factors and the cost to industry from this condition are also examined.
