Abstract

In chronic kidney disease (CKD), overweight and mild obesity have shown the lowest cardiovascular (CV) risk. However, central obesity has been directly associated with CV risk in these patients. This bidirectional relationship of body mass index (BMI) and central obesity prompted us to evaluate CV risk based on a combination of BMI and waist-to-hip ratio (WHR) in nondialysis CKD patients. We included 1078 patients with CKD stage 2 through 5 (nondialysis) enrolled in a nationwide prospective cohort of Korea. Patients were divided into 3 groups by BMI (normal BMI, 18.5-22.9; overweight, 23.0-27.4; and obese, 27.5 and over kg/m) and were dichotomized by a sex-specific median WHR (0.92 in males and 0.88 in females). Coronary artery calcification (CAC) was determined by multislice computed tomography. CAC (score above 10 Agatston units) was found in 477 patients. Multivariate logistic regression analysis indicated that BMI was not independently associated with CAC. However, WHR showed an independent linear and significant association with CAC (odds ratio, 1.036; 95% confidence interval, 1.007-1.065 per 0.01 increase). Furthermore, when patients were categorized into 6 groups according to a combination of BMI and WHR, normal BMI but higher WHR had the highest risk of CAC compared with the normal BMI with lower WHR group (2.104; 1.074-4.121). Thus, a normal BMI with central obesity was associated with the highest risk of CAC, suggesting that considering BMI and WHR, 2 surrogates of obesity, can help to discriminate CV risk in Korean nondialysis CKD patients.

摘要

在慢性肾脏病(CKD)中,超重和轻度肥胖的心血管(CV)风险最低。然而,在这些患者中,中心性肥胖与 CV 风险直接相关。这种体重指数(BMI)和中心性肥胖之间的双向关系促使我们根据非透析 CKD 患者的 BMI 和腰臀比(WHR)组合来评估 CV 风险。我们纳入了韩国一项全国前瞻性队列研究中的 1078 名 CKD 2 至 5 期(非透析)患者。患者根据 BMI(正常 BMI,18.5-22.9;超重,23.0-27.4;肥胖,27.5 及以上 kg/m)分为 3 组,并按性别特异性中位数 WHR(男性为 0.92,女性为 0.88)分为两组。通过多层螺旋 CT 确定冠状动脉钙化(CAC)。在 477 名患者中发现 CAC(积分高于 10 个 Agatston 单位)。多变量 logistic 回归分析表明,BMI 与 CAC 无独立相关性。然而,WHR 与 CAC 呈独立的线性显著相关性(比值比,1.036;95%置信区间,1.007-1.065,每增加 0.01)。此外,当根据 BMI 和 WHR 的组合将患者分为 6 组时,与 BMI 正常但 WHR 较高的组相比,BMI 正常但 WHR 较高的患者 CAC 风险最高(2.104;1.074-4.121)。因此,中心性肥胖的正常 BMI 与 CAC 风险最高相关,这表明考虑 BMI 和 WHR,2 种肥胖替代指标,有助于鉴别韩国非透析 CKD 患者的 CV 风险。
