Relationship between body composition and arterial function and its impacting factors / 中华健康管理学杂志

ABSTRACT

Objective To explore the relationship between body composition and arterial function index,especially augmentation index(AI),and make clear the impacts of gender and age on the relationship.Methotis A total of 3859 health adults were enrolled in this study.Boay composition was measured by bioelectrical impedance,and AI and pulse wave velocity(PWV) were viewed as indictors for arterial function.Correlation analysis and liner regression analysis were used for data comparison.Results Both body mass index(BMI) and body fat rate positively changed with PWV(r=0.114,both P<0.01).However,BMI showed no relation to AI(r=0.022,P>0.05).Body fat rate was positively and independently associated with AI(r=0.263, P<0.01),which was gender-dependent(femaler=0.219,P<0.01;maler=0.033,P>0.05).When age was concerned,above relationship was more stronger in participants ≤50 years(β=0.479 vs β=0.321,P<0.01).Conclusion Body fat mass may be a predicting factor of changes in AI.Gender and age could affect the relationship between body fat and rtery function.
