Abstract

en

Background

Low-density lipoprotein cholesterol (LDL-C) and diabetes mellitus are both modifiable risk factors for cardiovascular disease; however, whether elevated LDL-C levels confer a risk for diabetes remains unclear.

Objective

We aimed to examine the association between serum LDL-C concentrations at baseline and the risk of developing diabetes at follow-up in the general population of Chinese adults.

Methods

This study included 5274 adults aged ≥ 40 years from a community cohort who were without diabetes and followed for a median of 4.4 years. A standard 75-g oral glucose tolerance test was conducted at baseline and follow-up visits to diagnose diabetes. Logistic regression models and a restricted cubic spline were used to examine the association between baseline serum LDL-C levels and the risk of diabetes development. Subgroup analyses were conducted stratifying on age, sex, body mass index, hypertension, family history of diabetes, and LDL-C levels.

Results

A total of 652 participants (12%) developed diabetes during the follow-up period. Compared to quartile 1 of serum LDL-C, quartiles 2, 3, and 4 were associated with a 30%, 33%, and 30% significantly higher risk of diabetes, respectively after adjustment for confounders including homeostatic model assessment for insulin resistance. The linear relationship between baseline LDL-C down to 30.1 mg/dL and incident diabetes was demonstrated by restricted cubic spline analysis, and each 1-SD increase in LDL-C concentration (28.5 mg/dL) was associated with a 12% increase in the risk of diabetes (odds ratio 1.12, 95% confidence interval 1.03–1.22).

Conclusion

In this community-based general population, higher serum LDL-C levels were linearly associated with an elevated risk of incident diabetes.

摘要

zh

背景: 低密度脂蛋白胆固醇(LDL-C)和糖尿病都是心血管疾病的可改变风险因素; 然而,升高LDL-C水平是否会带来糖尿病的风险仍不清楚。本文旨在探讨在中国成年人中的基线血清LDL-C浓度与随访期间糖尿病风险之间的关联。

方法: 本研究包括5274名基线年龄≥40岁的社区队列参与者,他们无糖尿病且中位随访时间为4.4年。在基线和随访期间进行75g口服糖耐量试验以诊断糖尿病。使用逻辑回归模型和限制性立方样条来探讨基线血清LDL-C水平与糖尿病风险之间的关联。根据年龄、性别、BMI、高血压、糖尿病家族史和LDL-C水平进行亚组分析。

结果: 在随访期间,共有652名(12%)参与者发生糖尿病。校正包括HOMA-IR在内的混杂因素后,与血清LDL-C四分位组1相比,四分位组2、3和4的糖尿病风险分别显著增加30%、33%和30%。限制性立方样条分析显示基线LDL-C降至30.1mg/dl与糖尿病发病之间存在线性关系,LDL-C浓度每增加1个标准差(28.5mg/dl),糖尿病发病风险增加12% (OR 1.12, 95%CI 1.03 ~ 1.22)。

结论: 在基于社区的一般人群中,血清LDL-C水平升高与新发糖尿病的风险增加呈线性关系。
