-
摘要:
目的 评估血清非高密度脂蛋白胆固醇与高密度脂蛋白胆固醇比值(non-high density lipoprotein cholesterol/high density lipoprotein cholesterol, NHHR)、血浆致动脉粥样硬化指数(atherogenic index of plasma, AIP)与慢性肾病(chronic kidney disease, CKD)发病风险的关系, 为CKD的防治提供依据。 方法 以金昌队列中25 377名未患CKD的参与者作为研究对象, 采用Cox比例风险回归模型、限制性立方样条分别评估NHHR和AIP对CKD的发病风险及剂量-反应关系, 并进行亚组分析。采用受试者工作特征曲线评估NHHR和AIP对CKD发病风险的预测能力。 结果 经过平均4.77年的随访调查后, 新发CKD患者有1 213例, 发病密度为10.03/1 000人年。调整混杂因素后, 相较于Q1组, Q4组人群中NHHR和AIP的CKD发病风险比分别为1.270(95% CI: 1.066~1.512)和1.294(95% CI: 1.081~1.548), 且均存在一定的剂量-反应关系(均P<0.05)。NHHR和AIP预测CKD的AUC值分别为0.750(95% CI: 0.736~0.764)和0.735(95% CI: 0.721~0.749)。亚组分析发现, 吸烟和糖尿病与NHHR、糖尿病和AIP间存在交互作用(均P<0.05)。 结论 NHHR和AIP是CKD发病的独立危险因素, 并对CKD发病风险有一定的预测能力。 -

Abstract:Objective To analyse serum non-high-density lipoprotein cholesterol to high-density lipoprotein cholesterol ratio (NHHR), plasma atherogenic index (AIP) and the risk of chronic kidney disease (CKD). Methods A total of 25 377 participants without CKD from the Jinchang Cohort matched at baseline and follow-up were enrolled for the study. Cox proportional risk regression model and restricted cubic spline method were used to estimate the relationship between NHHR and AIP on the risk and dose response of CKD, and subgroup analyses were performed. Receiver operating characteristic curve and area under the curve (AUC) were conducted to evaluate the predictive ability on the risk of CKD. Results After an average follow-up period of 4.77 years, 1 213 new cases of CKD were identified, and the incidence density is 10.03/1 000 person-years. After adjusting for confounders, the HRs of NHHR and AIP in the Q4 population were 1.270 (95% CI: 1.066-1.512) and 1.294 (95% CI: 1.081-1.548), respectively, compared with the Q1 group, and all had dose-response relationship (all P < 0.05). The AUCs of NHHR and AIP for the prediction of CKD were 0.750 (95% CI: 0.736-0.764) and 0.735 (95% CI: 0.721-0.749), respectively. Subgroup analysis revealed interactions between smoking and diabetes with NHHR, and diabetes with AIP (all P < 0.05). Conclusions NHHR and AIP are independent risk factors for the development of CKD and have some predictive power with regard to the risk of CKD. -
