目的:探讨中老年人群残余胆固醇(RC)与心脑血管疾病发生风险的关联。方法:基于CHARLS数据库,前瞻性随访纳入的9302名≥45岁参与者9年(2011—2020年)。按RC三分位数将人群分为Q1、Q2、Q3三组。采用KM曲线分析不同组RC水平与心脑血管疾病发生的关联;采用单变量、多变量Cox回归分析RC与心脑血管疾病发生的关系。结果:不同RC水平组间年龄、性别、BMI、吸烟、居住地、高血压、糖尿病具有统计学差异(P<0.05)。KM曲线显示,随RC水平升高,心血管疾病与脑卒中的累计发生率递增,组间差异显著(P<0.001)。Cox回归分析显示,RC是心脑血管疾病的显著危险因素。在未校正(模型1)、部分校正(模型2)及完全校正(模型3)后,RC作为连续变量均与心血管疾病及脑卒中风险显著相关(所有HR>1,P<0.05),且风险随校正因素增加仍持续存在。RC三分位数分类进行Cox回归分析发现模型1-3中Q2、Q3是心血管疾病的危险因素(均HR>1,P<0.05);模型1、2中Q2、Q3是脑卒中的危险因素(均HR>1,P<0.05),模型3中仅Q3是脑卒中的危险因素[HR (95%CI) 1.30 (1.08~1.55),P=0.005]。结论:中老年人群中,RC是心脑血管疾病的独立危险因素,其水平越高,疾病发生风险越大,应加强对高RC水平人群的管理以预防心脑血管疾病。

中老年人群残余胆固醇与心脑血管疾病发生风险的关联性研究
Objective: To explore the association between remnant cholesterol (RC) and cardiovascular and cerebrovascular diseases in middle-aged and elderly people.Methods: Based on the CHARLS database, 9302 participants aged ≥ 45 years were prospectively followed up for 9 years (2011-2020). According to the RC tertile, the population was divided into three groups: Q1, Q2 and Q3. KM curve was used to analyze the correlation between RC level and cardiovascular and cerebrovascular diseases in different groups. The relationship between RC and the occurrence ofcardiovascular and cerebrovascular diseases was analyzed by univariate and multivariate Cox regression.Results: There were significant differences in age, gender, BMI, smoking, place of residence, hypertension and diabetes between different RC levels (P < 0.05). The KM curve showed that the cumulative incidence of cardiovascular disease and stroke increased with the increase of RC level, and the difference between groups was significant (P < 0.001). Cox regression analysis showed that RC was a significant risk factor for cardiovascular and cerebrovascular diseases. After uncorrected (Model 1), partially corrected (Model 2) and fully corrected (Model 3), RC as a continuous variable was significantly associated with the risk of cardiovascular disease and stroke (all HR > 1, P < 0.05), and the risk continued with the increase of correction factors. Cox regression analysis using RC tertile classification revealed that Q2 and Q3 were risk factors for cardiovascular disease in Models 1-3 (both HR > 1, P < 0.05); In Models 1 and 2, Q2 and Q3 were risk factors for stroke (both HR > 1, P < 0.05), while in Model 3, only Q3 was a risk factor for stroke [HR (95% CI) 1.30 (1.08-1.55), P = 0.005].Conclusion: In the middle-aged and elderly population, RC is an independent risk factor for cardiovascular and cerebrovascular diseases. The higher the level, the greater the risk of disease. The management of people with high RC levels should be strengthened to prevent cardiovascular and cerebrovascular diseases.
