Outline of Final Research Achievements

Varicose veins (VVs) increase in prevalence with age. Leg symptoms caused by VVs affect quality of life and labor productivity. However, less information is available. In this study, we conducted an epidemiological survey of VVs using an echo equipment for elderly people using the research base of the Shimane CoHRE Study. We have clarified that standing work with low movement, family history, gender (female) and lifestyle are associated with the occurrence of VVs in lower extremities. We further conducted to determine the familial aggregation of VVs from the point of genetic and environmental factor using adoptees model of Swedish Nation-wide database. The effect of genetic factor was confirmed and we further found the additive effect of familial environmental factor. These results are of worth for the future prevention strategy of VVs. In Japan, where we are in the age of a super-aging society, our research may contribute the maintenance of health in the lower extremities.
