Abstract

The influence of body fat on arterial stiffness remains controversial. This study was performed to investigate the associations between four different types of body fat parameters and brachial-ankle pulse wave velocity (baPWV). A total of 3758 subjects (mean age, 53.4 ± 8.8 years; females, 36.3%) who underwent health check-up were retrospectively analyzed. Anthropometric parameters including body mass index (BMI), waist circumference (WC) and waist-hip ratio (WHR) were assessed, and visceral fat area (VFA) was calculated by bioelectrical impedance analysis. In simple linear correlation analyses, baPWV was associated with WC, WHR and VFA (P < 0.001 for each), but not with BMI (P = 0.175). In multivariable analyses, BMI and WC were not associated with baPWV (P > 0.05 for each). Even after controlling for potential confounders, higher baPWV was significantly associated not only with higher WHR [for > 0.90 in men and > 0.85 in women: odds ratio (OR), 1.23; 95% confidence interval (CI), 1.06-1.42; P = 0.005; for the highest tertile compared to the lowest tertile: OR, 1.38; 95% CI, 1.15-1.66; P < 0.001], but also with higher VFA (for ≥ 100 cm: OR, 1.39; 95% CI, 1.20-1.60; P < 0.001; for the highest tertile compared to the lowest tertile: OR, 1.77; 95% CI, 1.48-2.12; P < 0.001). Our study showed that baPWV was correlated with WHR and VFA, but not with BMI and WC. This implies that arterial stiffness may be more strongly associated with abdominal obesity than overall obesity.

摘要

体脂对动脉僵硬度的影响仍存在争议。本研究旨在探讨四种不同类型体脂参数与肱踝脉搏波速度(baPWV)之间的关系。共回顾性分析了 3758 名接受健康检查的受试者(平均年龄 53.4±8.8 岁;女性占 36.3%)。评估了人体测量参数,包括体重指数(BMI)、腰围(WC)和腰臀比(WHR),并通过生物电阻抗分析计算了内脏脂肪面积(VFA)。在简单线性相关分析中,baPWV 与 WC、WHR 和 VFA 相关(P 值均<0.001),但与 BMI 不相关(P=0.175)。在多变量分析中,BMI 和 WC 与 baPWV 不相关(P 值均>0.05)。即使在控制了潜在混杂因素后,较高的 baPWV 与较高的 WHR 显著相关[男性>0.90 和女性>0.85:比值比(OR)为 1.23;95%置信区间(CI)为 1.06-1.42;P=0.005;与最低三分位相比,最高三分位:OR 为 1.38;95%CI 为 1.15-1.66;P<0.001],也与较高的 VFA 相关[≥100 cm:OR 为 1.39;95%CI 为 1.20-1.60;P<0.001;与最低三分位相比,最高三分位:OR 为 1.77;95%CI 为 1.48-2.12;P<0.001]。我们的研究表明,baPWV 与 WHR 和 VFA 相关,而与 BMI 和 WC 不相关。这表明动脉僵硬度可能与腹部肥胖的关系比全身肥胖更密切。
