Triglycerides (TG) to high-density lipoprotein cholesterol (HDL-C) ratio (TG/HDL-C) has been recommended as a surrogate marker for insulin resistance. In the present study, we aimed to investigate the relationship between TG/HDL-C and NAFLD in an apparently healthy population.
A total of 18,061 subjects who participated in a health checkup program were included. NAFLD was diagnosed by ultrasonography.
The prevalence rate of NAFLD was 24.8% in the whole population, and progressively increased across the quartiles of TG/HDL-C (4.9, 14.1, 26.8 and 53.5%, respectively, P < 0.001). After adjustment for confounding factors, TG/HDL-C was independently associated with the risk of NAFLD. Compared with the first quartile of TG/HDL-C (Q1), the odds ratios (95% confidence intervals) for NAFLD in the increasing quartiles (Q2-Q4) were 2.1(1.8-2.6), 3.6 (3.0-4.3) and 9.2(7.6-11.1), respectively. In addition, the area under receiver operator characteristic curve (95% confidence interval) of TG/HDL-C for NAFLD was 0.85 (0.84-0.86) in women and 0.79 (0.78-0.80) in men, significantly higher than that of TG, TC, LDL-C, HDL-C, ALT and AST (P < 0.05). The optimal cutoff point of TG/HDL-C for detection of NAFLD was 0.9 in women (sensitivity = 78.8%, specificity = 77.3%) and 1.4 in men (sensitivity = 70.7%, specificity = 73.5%).
TG/HDL-C is independently associated with NAFLD in apparently healthy individuals and may be used as a surrogate for NAFLD.
甘油三酯（TG）与高密度脂蛋白胆固醇（HDL-C）的比值（TG/HDL-C）已被推荐为胰岛素抵抗的替代标志物。本研究旨在探讨 TG/HDL-C 与非酒精性脂肪性肝病（NAFLD）在健康人群中的关系。
共纳入 18061 名参加健康体检计划的受试者。NAFLD 通过超声诊断。
全人群中 NAFLD 的患病率为 24.8%，且随着 TG/HDL-C 四分位区间（4.9、14.1、26.8 和 53.5%，P<0.001）逐渐升高。调整混杂因素后，TG/HDL-C 与 NAFLD 的发生风险独立相关。与 TG/HDL-C 四分位区间最低的第一分位（Q1）相比，分位区间（Q2-Q4）的 NAFLD 比值比（95%置信区间）分别为 2.1（1.8-2.6）、3.6（3.0-4.3）和 9.2（7.6-11.1）。此外，女性 TG/HDL-C 预测 NAFLD 的受试者工作特征曲线下面积（95%置信区间）为 0.85（0.84-0.86），男性为 0.79（0.78-0.80），均显著高于 TG、TC、LDL-C、HDL-C、ALT 和 AST（P<0.05）。女性 TG/HDL-C 检测 NAFLD 的最佳截断值为 0.9（敏感性=78.8%，特异性=77.3%），男性为 1.4（敏感性=70.7%，特异性=73.5%）。
在健康人群中，TG/HDL-C 与 NAFLD 独立相关，可作为 NAFLD 的替代标志物。
