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) 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 < 0.05). On multivariate logistic regression analysis, the results suggested that higher diastolic blood pressure [OR: 1.021, 95% CI (1.002, 1.040), = 0.030], insulin treatment [currently used: OR = 2.156, 95% CI (1.249, 3.724), = 0.006], higher level of fasting plasma glucose [OR: 1.819, 95% CI (1.598, 2.069), < 0.001], and visceral obesity [OR: 1.876, 95% CI (1.158, 3.038), = 0.011] were risk factors for poor glycemic control.

CONCLUSION

This study indicated that visceral obesity (visceral fat area ≥ 100cm) 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.
