Abstract: Objective To investigate the relationship between body composition and branchial-ankle pulse wave velocity (baPWV) in the elderly of different genders. Methods A total of 1703 elderly people who participated in community health examination in Dongfeng community of Bengbu City from January to December 2021 were consecutively enrolled. Body composition and baPWV were measured by body composition analyzer and automatic arteriography detector, respectively. Results Among 1703 elderly patients, 1452 (85.3%) presented with atherosclerosis (baPWV≥14.0 m/s). Pearson correlation analysis showed that the levels of waist circumference (WC), body mass index (BMI), body roundness index (BRI), total body water (TBW), body fat porcentage (%BF) and total fat mass (TFM) were positively correlated with the level of baPWV in the elderly women; The ratio of arm muscle mass (RAMM), ratio of arm fat-free mass (RAFFM),ratio of leg muscle mass (RLMM), ratio of leg fat-free mass (RLFFM), ratio of trunk muscle mass (RTMM) and ratio of trunk fat-free mass (RTFFM) were negatively correlated with the level of baPWV in the elderly women. Only the level of %BF was positively correlated with the level of baPWV in the elderly men. Multiple linear stepwise regression analysis showed that systolic blood pressure (SBP), age, heart rate (HR) and %BF were the main influencing factors of baPWV in the elderly men, and SBP, age, HR, %BF, RTMM, BMI, TFM and pulse pressure gap (PP) were the main influencing factors of baPWV in the elderly women. Conclusions The incidence of atherosclerosis in the community elderly is high, and the body composition indexes show effects on baPWV in the elderly women.
