Relationships between symptoms and venous disease - The San Diego population study

Background: The associations between symptoms and venous disease of the lower extremities are poorly characterized. Methods: We conducted a cross-sectional Study to evaluate relationships between symptoms associated with venous disease and prevalent disease in 2408 men and women aged 29 to 91 years who were employees, retirees, or spouses at a large state university. Index participants were randomly selected within strata by age, sex, and ethnicity. A structured interview assessed the prevalence of aching, itching, heaviness, tired legs, cramping, swelling, and nighttime restless legs. A comprehensive standardized examination determined the prevalence of visible disease (normal, telangiectasias, varicose veins, and trophic changes) and functional disease (normal, superficial, and deep disease). We related symptoms to disease with attention to modification by sex, ethnicity, and age. Results: Aching, itching, heaviness, tired legs, cramping, and swelling were related to both superficial and deep functional disease, The same symptoms were related to varicose veins and trophic changes. Swelling and heaviness were related to telangiectatic disease. Except for restless legs and trophic changes, the prevalence of symptoms across each category was greater in women than men, Aching was the most common symptom but was relatively nonspecific, Swelling was the most specific marker for prevalent visible and functional disease, Heaviness and itching also helped to distinguish prevalent disease. Conclusions: Venous symptoms were more prevalent in study participants with both visible and functional disease and in women. Swelling was the most specific predictor heaviness, itching,and aching also helped to distinguish cases.
