不同性别老年人体成分与臂-踝脉搏波传导速度的相关性研究

Correlation between body composition and branchial⁃ankle pulse wave velocity in the elderly of different genders

目的 探讨不同性别老年人体成分与臂-踝脉搏波传导速度(baPWV)之间的关系。方法 连续纳入2021年1~12月蚌埠市东风社区参加社区健康体检的老年人1703例,使用人体成分分析仪和全自动动脉硬化检测仪分别测定体成分和baPWV。结果 1703例老年人中,检出动脉硬化者(baPWV≥14.0 m/s)1452例,检出率为85.3%。Pearson相关分析显示,老年女性的腰围(WC)、BMI、身体圆度指数(BRI)、总水分(TBW)、体脂率(%BF)和总脂肪量(TFM)与baPWV呈正相关,上肢肌肉量比值(RAMM)、上肢无脂肪量比值(RAFFM)、下肢肌肉量比值(RLMM)、下肢无脂肪量比值(RLFFM)、躯干肌肉量比值(RTMM)和躯干无脂肪量比值(RTFFM)与baPWV呈负相关;老年男性只有%BF与baPWV呈正相关。多元线性逐步回归分析显示,SBP、年龄、心率(HR)、%BF是老年男性baPWV的主要影响因素;SBP、年龄、HR、%BF、RTMM、BMI、TFM、脉压差(PP)是老年女性baPWV的主要影响因素。结论 社区老年人动脉硬化的发生率处于高水平,老年女性体成分指标对baPWV的影响更大。

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.
