Association Between Visceral Obesity and Glycemic Control in Patients with Type 2 Diabetes Mellitus: A Retrospective Study

Purpose: To investigate the association between visceral obesity and glycemic control in patients with type 2 diabetes mellitus. Patients and Methods: A retrospective analysis involved 714 patients diagnosed with type 2 diabetes mellitus from the National Metabolic Management Center from November 2021 to February 2024. Medical data included sociodemographic data, lifestyle behaviors, and anthropometric and biochemical measurements. Multivariate logistic regression analysis was used to analyze their associations. Results: Among the patients, 251 (35.2%) achieved good glycemic control (HbA1c < 7.0%). On univariate analysis, higher diastolic blood pressure, longer duration of type 2 diabetes mellitus, tobacco smoking, alcohol drinking, insulin treatment, higher levels of fasting plasma glucose, homeostasis model assessment of insulin resistance, triglyceride, total cholesterol, and low-density lipoprotein cholesterol, visceral obesity (visceral fat area ≥ 100cm 2 ) and diabetic peripheral neuropathy were all positively correlated with poor glycemic control; female, older age, higher levels of C peptide and serum uric acid were inversely associated with poor glycemic control (all P < 0.05). On multivariate logistic regression analysis, the results suggested that higher diastolic blood pressure OR: 1.021, 95% CI (1.002, 1.040), P = 0.030, insulin treatment currently used: OR = 2.156, 95% CI (1.249, 3.724), P = 0.006, higher level of fasting plasma glucose OR: 1.819, 95% CI (1.598, 2.069), P < 0.001, and visceral obesity OR: 1.876, 95% CI (1.158, 3.038), P = 0.011 were risk factors for poor glycemic control. Conclusion: This study indicated that visceral obesity (visceral fat area ≥ 100cm 2 ) is positively associated with poor glycemic control, and serves as an independent risk factor for poor glycemic control (HbA1c ≥ 7.0%) in patients with type 2 diabetes mellitus. Screening for visceral obesity should be emphasized, and targeted interventions should be taken to improve glycemic control in patients with type 2 diabetes mellitus.
