Abstract

We aimed to investigate the influence of cardiorespiratory fitness (CRF) and body composition on arterial stiffness. Carotid-to-femoral pulse wave velocity (cfPWV) and aortic systolic (ASBP) and diastolic (ADBP) blood pressure were compared between upper and lower tertiles of oxygen consumption at the aerobic threshold (VO), peak oxygen consumption (VO), percentage of fat mass (FM%), and body mass index (BMI) in sixty adolescents (30 males and 30 females, 14.9 ± 2.1 years old). A stepwise multivariable linear regression analysis was performed to investigate the independent associations between VO and VO and cfPWV, and between BMI and FM% and cfPWV with adjustments for age, sex, ASBP, and ADBP. cfPWV and ADBP were lower in the second and third VO tertiles compared to the first tertile (cfPWV, 4.7 ± 0.5 and 4.7 ± 0.5 vs. 5.3 ± 0.8 m/s, < 0.01; ADBP, 62 ± 7 and 62 ± 7 vs. 70 ± 8 mmHg, < 0.01). ASBP was lower in the third VO tertile compared to the first tertile (94 ± 7 vs. 101 ± 12 mmHg, = 0.05). ADBP was lower in the second VO tertile compared to the first tertile (62 ± 7 vs. 68 ± 9 mmHg, = 0.03). ASBP was lower in the first and second BMI tertiles compared to the third tertile (95 ± 8 and 95 ± 7 vs. 102 ± 11 mmHg, = 0.02). The eight-variable model significantly contributed to the variance of cfPWV (F(8, 51) = 7.450, < 0.01), accounting for 47% of the variance. Individually, age ( < 0.05) and ADBP ( < 0.01) significantly predicted cfPWV. Submaximal indicators of CRF such as VO should be considered as a part of the risk stratification of cardiovascular disease in healthy adolescents.

摘要

我们旨在研究心肺适能(CRF)和身体成分对动脉僵硬度的影响。比较了60名青少年(30名男性和30名女性,年龄14.9±2.1岁)在有氧阈值时的耗氧量(VO)、峰值耗氧量(VO)、脂肪量百分比(FM%)和体重指数(BMI)的上三分位数和下三分位数之间的颈股脉搏波速度(cfPWV)、主动脉收缩压(ASBP)和舒张压(ADBP)。进行逐步多变量线性回归分析,以研究VO和VO与cfPWV之间,以及BMI和FM%与cfPWV之间的独立关联,并对年龄、性别、ASBP和ADBP进行了校正。与第一个VO三分位数相比,第二个和第三个VO三分位数的cfPWV和ADBP较低(cfPWV,4.7±0.5和4.7±0.5 vs. 5.3±0.8 m/s,<0.01;ADBP,62±7和62±7 vs. 70±8 mmHg,<0.01)。与第一个VO三分位数相比,第三个VO三分位数的ASBP较低(94±7 vs. 101±12 mmHg,=0.05)。与第一个VO三分位数相比,第二个VO三分位数的ADBP较低(62±7 vs. 68±9 mmHg,=0.03)。与第三个BMI三分位数相比,第一个和第二个BMI三分位数的ASBP较低(95±8和95±7 vs. 102±11 mmHg,=0.02)。八变量模型对cfPWV的方差有显著贡献(F(8, 51) = 7.450,<0.01),占方差的47%。单独来看,年龄(<0.05)和ADBP(<0.01)显著预测了cfPWV。CRF的次最大指标如VO应被视为健康青少年心血管疾病风险分层的一部分。
