摘要:

目的 研究普通体检人群糖化血红蛋白(HbA1c)水平与颈动脉内膜-中膜厚度(CIMT)的相关性。方法 选取9 881例普通体检人群为研究对象,其中男7 091例,女2 790例,采用血管彩色多普勒超声测量CIMT。根据是否有CIMT增厚,分为增厚组(4 513例)和正常组(5 368例)。收集2组的一般资料和实验室资料并进行比较。采用Logistic回归分析总人群及不同性别中CIMT增厚的危险因素。采用受试者工作特征(ROC)曲线评价HbA1c水平对CIMT增厚的预测效果。结果 与正常组相比,增厚组的男性比例、年龄、体质量指数(BMI)、收缩压(SBP)、直接胆红素(DBIL)、球蛋白(GLB)、血尿素氮(BUN)、血肌酐(Scr)、血糖(GLU)、HbA1c、总胆固醇(TC)和低密度脂蛋白胆固醇(LDL-C)水平均升高,而估算肾小球滤过率(eGFR)、丙氨酸转氨酶(ALT)、白蛋白(ALB)、高密度脂蛋白胆固醇(HDL-C)降低(P<0.05)。多因素Logistic回归分析显示,在总人群中高龄,男性,ALB、GLU、LDL-C升高,HbA1c≥5.7%是CIMT增厚的危险因素,GLB、HDL-C升高是CIMT增厚的保护因素。男性人群中高龄,ALB、LDL-C升高,HbA1c≥5.7%是CIMT增厚的危险因素,ALT、GLB、HDL-C升高是CIMT增厚的保护因素;女性人群中SBP、TC升高,HbA1c≥5.6%是CIMT增厚的危险因素,BMI、eGFR、ALB、Scr、HDL-C升高是CIMT增厚的保护因素。ROC曲线结果分析显示,HbA1c在总人群、男性和女性中预测CIMT增厚的最佳截断值均为5.65%,女性中HbA1c对CIMT增厚的预测效能较优。结论 在普通人群中HbA1c水平升高为CIMT增厚的危险因素,且在女性人群中,HbA1c对CIMT增厚的影响更大。

Abstract:

Objective To study the correlation between glycosylated hemoglobin (HbA1c) level and carotid intima-media thickness (CIMT) thickening in general physical examination population. Methods A total of 9 881 cases with general physical examination were selected as the research object, including 7 091 males and 2 790 females. CIMT was measured by vascular color Doppler ultrasound. According to whether there was CIMT thickening, the cases were divided into the thickening group (4 513 cases) and the normal group (5 368 cases). The general data and laboratory data of the two groups were collected and compared. Logistic regression was used to analyze the risk factors of CIMT thickening in the general population and different genders. Receiver operating characteristic curve (ROC) was used to evaluate the predictive effect of the HbA1c level on CIMT thickening. Results Compared to the normal group, male proportion, age, body mass index (BMI), systolic blood pressure (SBP), direct bilirubin (DBIL), globulin (GLB), blood urea nitrogen (BUN), blood creatinine (Scr), blood glucose (GLU), HbA1c, total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels were increased in the thickening group. The glomerular filtration rate (eGFR), alanine aminotransferase (ALT), albumin (ALB) and high density lipoprotein cholesterol (HDL-C) were decreased (P<0.05). Logistic regression analysis showed that in the total population, advanced age, male, ALB, GLU and LDL-C increased, and HbA1c≥5.7% was risk factors for CIMT thickening, while increased GLB and HDL-C were protective factors for CIMT thickening. In males, advanced age, increased ALB and LDL-C, and HbA1c≥5.7% were risk factors for CIMT thickening, while increased ALT, GLB and HDL-C were protective factors for CIMT thickening. In females, increased SBP and TC and HbA1c≥5.6% were risk factors for CIMT thickening, while increased BMI, eGFR, ALB, Scr and HDL-C were protective factors for CIMT thickening. ROC curve analysis showed that the optimal cut-off value of HbA1c in predicting CIMT thickening was 5.65% in the total population, males and females, and HbA1c has better predictive efficiency for CIMT thickening in females. Conclusion The elevated HbA1c levels are a risk factor for CIMT thickening in the general population, and HbA1c has a greater effect on CIMT thickening in the females.
