Demographic Determinants Influencing the Adoption of Genetic Testing for Cardiovascular Diseases in Japan　― Insights From a Large-Scale Online Survey ―

Abstract

Background: Genetic testing for cardiovascular diseases (CVD) is vital, but is underutilized in Japan due to limited insurance coverage, accessibility, and public disinterest. This study explores demographic factors influencing the decision to undergo CVD genetic testing. Methods and Results: We compared the CVD history and baseline demographics of Japanese adults who underwent genetic testing with those who did not, using an Internet survey. The regression model indicated that men, the young, married individuals, parents, and those with CVD, higher score for rationality, and lower quality of life were more inclined to undergo testing. Conclusions: Targeting strategies for CVD genetic testing could focus on these demographics.
