Relationship between hs-CRP and HbA1c in Diabetes Mellitus Patients: 2015-2017 Korean National Health and Nutrition Examination Survey / 전남의대학술지

ABSTRACT

This study aimed to examine the relationship between hemoglobin A1c (HbA1c), one of the indicators of diabetes, and high sensitivity C-reactive protein (hs-CRP), one of the indicators of inflammation. Raw data from the Korean National Health and Nutrition Examination Survey (KNHANES, 2015-2017) was analyzed. Among the patients diagnosed with diabetes, 1,479 adults were selected as subjects for our study, and their HbA1c levels, hs-CRP levels, sex, age, body mass index (BMI), waist circumference, level of triglycerides and high-density lipoprotein (HDL)-cholesterol, hypertension, receipt of diagnosis, monthly average income, education, and drinking and smoking habits were recorded. Multiple regression analysis of hs-CRP was performed by dividing hs-CRP into quartiles using HbA1c as the dependent variable. In Model 1, sex, age, and BMI were adjusted, and in Model 2, sex, age, BMI, waist circumference, level of triglycerides and HDL-cholesterol, hypertension, and receipt of diagnosis were adjusted. In Model 3, Model 2 parameters along with monthly average household income, education level, and drinking and smoking habits were adjusted. HbA1c levels increased as the hs-CRP quartile increased, that is, 2nd Quartile=0.307, p=0.003; 3rd Quartile=0.431, p=0.001; and 4 th Quartile=0.550, p=0.001. Of the various factors related to diabetes, this study examined the relationship between inflammation and diabetes.
