代谢综合征与非代谢综合征人群不同血脂成分对2型糖尿病发病风险的影响

目的通过前瞻性研究比较non-HDL-C、LDL-C在代谢综合征（MS）人群、非MS人群中与2型糖尿病（T2DM）发病的关系。方法将各血脂指标按水平三等分，以不患MS且血脂水平处于第一等分组的人群为对照组，比较MS、非MS人群各血脂水平与T2DM发病的关系。结果MS人群的血脂水平明显高于非MS人群。非MS人群中，TG、non-HDL-C、LDL-C水平在第三等分组时发生T2DM的风险最高。MS人群发生T2DM的风险均高于同血脂水平的非MS人群，但第三等分组发生T2DM的相对危险度（RR值）并没有增加。结论MS人群发生T2DM的风险高于非MS人群，但其发生T2DM的风险并没有随血脂水平的增高而增加。而非MS人群中，non-HDL-C、LDL-C在第三等分组发生T2DM的风险最高，且non-HDL-C的预测作用强于LDL-C。

The effects of the different blood lipid components on the T2DM occurrence in metabolic syndrome(MS) versus non-MS patients

Objective The effects of the different blood lipid components on the T2DM occurrence in metabolic syndrome （MS） versus non-MS patients. Methods The risk ratio （RR） of type 2 diabetes occurrence was assessed based on different blood lipid componet effects in MS versus non-MS patients. Results Patients with MS had a higher T2DM RR than those without MS. In a multivariate model, T2DM risk in MS population didn＇t increase with increasing lipid. While in non-MS population, the third trisection of non-HDL-C, LDL-C had the highest RRs of 1. 691.06-2.68] in non-HDL-C of the third trisection, and 1. 6411.02-2.63]in LDL-C of the third trisection （all P〈0.05）. Conclusions Non-HDL is a stronger predictor for T2DM occurrence among the non-MS population than LDL, and it should be given more consideration in the clinical approach to risk reduction among non-MS populations.
