Compare arterial stiffness among law enforcement officers (LEOs) versus general population normative values and identify predictors of arterial stiffness in LEOs.
Seventy male LEOs (age: 24-54 years) completed body composition, blood pressures, physical activity level, and carotid-femoral pulse wave velocity (cfPWV) measurements. T-tests and regression analyses were utilized to compare LEO data to normative data and predict cfPWV, respectively.
Compared to similar age strata within the general population, cfPWV was lower among LEO's under 30-years (mean difference = -0.6 m·s), but higher among LEOs 50-55-years (mean difference = 1.1 m·s). Utilizing regression, age, relative body fat, and diastolic blood pressure explained the greatest variance in LEO's cfPWV (adj. R = 0.56, < 0.001).
This investigation demonstrated that arterial stiffness may progress more rapidly in LEOs and LEOs' relative body fat and blood pressure may primarily affect arterial stiffness and risk of CVD.
比较执法人员（LEO）与普通人群的动脉僵硬度正常值，并确定 LEO 动脉僵硬度的预测因素。
70 名男性 LEO（年龄：24-54 岁）完成了身体成分、血压、身体活动水平和颈股脉搏波速度（cfPWV）测量。采用 t 检验和回归分析分别比较 LEO 数据与正常值，并预测 cfPWV。
与普通人群中相似年龄组相比，30 岁以下的 LEO 的 cfPWV 较低（平均差异=-0.6m·s），但 50-55 岁的 LEO 的 cfPWV 较高（平均差异=1.1m·s）。利用回归分析，年龄、相对体脂和舒张压解释了 LEO 的 cfPWV 最大的变异性（调整后的 R=0.56，<0.001）。
本研究表明，动脉僵硬度在 LEO 中可能会更快地进展，而 LEO 的相对体脂和血压可能主要影响动脉僵硬度和 CVD 风险。
