Prevalence of dyslipidemia and the relationship between HbA1C and lipid profile in Moroccan patients with T2DM: a cross-sectional study.

Abstract

the increased prevalence of dyslipidemia in patients with type 2 diabetes mellitus (T2DM) results from uncontrolled hyperglycemia and consistently contributes to an elevated risk of cardiovascular complications. This study sought to estimate the prevalence of dyslipidemia and to investigate the relationship between glycated hemoglobin (HbA1C) and serum lipid levels in Moroccan patients with T2DM. a total of 505 patients with T2DM were included in this cross-sectional study, 77.4% with chronic complications and 22.6% without. The collected data were examined using statistical package for the social sciences (SPSS) version 20.0 software and appropriate statistical methods. the data analysis showed that the mean and SD of age were 57.27±10.74 years. Among 505 patients with T2DM, the prevalence of hypercholesterolemia, hypertriglyceridemia, increased low-density lipoprotein cholesterol (LDL-C), and decreased HDL-C was 41.4%, 35.9%, 27.1%, and 17%, respectively. In addition, the data analysis showed that levels of total cholesterol (TC) (p≤0.001), triglycerides (p≤0.001), Low-density lipoprotein cholesterol (LDL-C) (p≤0.001), TC/HDL-C ratio (p=0.006), and LDL-C/HDL-C ratio (p=0.006) were significantly higher in T2DM patients with complications as compared to those without complications. The patients with HbA1C > 7.0% had significantly higher values of fasting blood glucose (FBG) (p≤0.001), total cholesterol (p≤0.001), triglycerides (p≤0.001), and TC/HDL-C ratio (p=0.025) as compared to the patients with HbA1C ≤ 7.0%. The HbA1C demonstrated a significant negative correlation with age (r=-0.139), and positive correlation with FBG (r=0.673), total cholesterol (r=0.189) and triglycerides (r=0.243). our results showed that HbA1C is the most important biomarker of long-term glycemic control and can also be a good indicator of the lipid profile.
