Abstract
Background: Apolipoprotein B (ApoB), a key component of atherogenic lipoproteins, has been increasingly implicated in cardiometabolic disorders beyond dyslipidemia. However, its role in glycemic dysregulation remains unclear. This study aimed to investigate the association between ApoB levels and glycemic parameters, including fasting glucose, insulin resistance, and glycated hemoglobin (HbA1c), in individuals without diagnosed diabetes. Methods: This study was conducted at the National Research Cardiac Surgery Center (Kazakhstan) over the period between 2023 and 2024 as a cross-sectional analysis. Adults aged ≥ 20 years without diagnosed diabetes and with complete data on their ApoB and glycemic markers were included. Associations between ApoB and fasting plasma glucose (FPG), HbA1c, and HOMA-IR were assessed using multivariable linear and logistic regression models adjusted for demographic, lifestyle, and metabolic covariates. Results: Higher ApoB levels were significantly associated with increased fasting glucose (β = 2.07 mg/dL per 1-SD increase in ApoB, p < 0.001), higher HbA1c (β = 0.06%, p < 0.001), and elevated HOMA-IR (β = 0.54, p < 0.001). Participants in the highest ApoB quartile had 53% higher odds of prediabetes (adjusted OR = 1.53; 95% CI: 1.22–1.91; p < 0.001) compared to the lowest quartile. These associations remained significant after adjusting for BMI, lipid levels, and other confounders. Conclusions: Elevated ApoB is independently associated with adverse glycemic profiles in nondiabetic individuals, suggesting its potential role in early glucose metabolism disturbances.
