Abstract

Purpose: This study investigated the association between the low-density lipoprotein-cholesterol/high-density lipoprotein-cholesterol (LDL-C/HDL-C) ratio and the incidence of diabetes in a Korean community-based cohort.Methods: The participants were 7,653 adults aged 40-69 years without diabetes at baseline from Korean Genome and Epidemiology Study who were followed up for 16 years biennially. These participants were categorized into four groups (Q1-Q4) according to quartiles of LDL-C/HDL-C ratio at baseline. Significant differences in the probability of diabetes-free survival curve were identified using the log-rank test in Kaplan-Meier analysis. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards regression analysis.Results: In total, 1,833 (24.0%) participants newly developed diabetes. The overall incidence of diabetes was 20.37 per 1,000 person-years (14.94, 17.12, 22.0, and 22.08 per 1,000 person-years for Q1, Q2, Q3, and Q4, respectively). The probability of diabetes-free survival was significantly different among the four groups (log-rank, x2=117.88, p<.001). Covariates included age, sex, triglyceride, fasting plasma glucose, homeostatic model assessment for insulin resistance index, hypertension, body mass index, family history of diabetes mellitus, smoking status, and alcohol use. Multivariate Cox proportional hazards regression showed that people with the highest quartile of the LDL-C/HDL-C ratio had a 1.17 times higher (HR=1.17, 95% CI: 1.01~1.35, p=.038) risk of diabetes development than those in the lowest quartile after adjusting for covariates.Conclusion: The LDL-C/HDL-C ratio is an independent risk factor for diabetes development. Measuring and managing the LDL-C/HDL-C ratio is necessary for detecting individuals at high risk for developing diabetes.
韩国成人低密度脂蛋白-胆固醇与高密度脂蛋白-胆固醇比值与2型糖尿病发病率之间的关系:韩国社区队列研究的辅助数据分析
目的:本研究在韩国社区队列中调查低密度脂蛋白-胆固醇/高密度脂蛋白-胆固醇(LDL-C/HDL-C)比率与糖尿病发病率之间的关系。方法:研究对象为7653名来自韩国基因组和流行病学研究的40-69岁无糖尿病的成年人,每两年随访16年。这些参与者根据基线时LDL-C/HDL-C比率的四分位数分为四组(Q1-Q4)。Kaplan-Meier分析中的log-rank检验发现无糖尿病生存曲线的概率存在显著差异。采用Cox比例风险回归分析计算风险比(hr)和95%置信区间(ci)。结果:共有1833名(24.0%)参与者新发糖尿病。糖尿病的总发病率为20.37 / 1000人年(Q1、Q2、Q3和Q4分别为14.94、17.12、22.0和22.08 / 1000人年)。四组患者无糖尿病生存的概率差异有统计学意义(log-rank, x2=117.88, p< 0.001)。协变量包括年龄、性别、甘油三酯、空腹血糖、胰岛素抵抗指数的稳态模型评估、高血压、体重指数、糖尿病家族史、吸烟状况和酒精使用。多因素Cox比例风险回归分析显示,LDL-C/HDL-C比值最高的四分位数人群发生糖尿病的风险是最低四分位数人群的1.17倍(HR=1.17, 95% CI: 1.01~1.35, p= 0.038)。结论:LDL-C/HDL-C比值是糖尿病发生的独立危险因素。测量和管理LDL-C/HDL-C比值对于发现糖尿病高危人群是必要的。
