Abstract

Background
The prevalence of type 2 diabetes mellitus has continued to rise. Although many studies have focused on the connection between weight loss and glucose control, only a few studies have investigated the association between body mass index (BMI) and glucose control status. We examined the association between glucose control and obesity.
Methods
We analyzed 3,042 participants with diabetes mellitus who were aged ≥19 years when they participated in the 2014 to 2018 Korean National Health and Nutrition Examination Survey. The participants were divided into four groups according to their BMI (<18.5, 18.5–23, 23–25, and ≥25 kg/m² ). We used guidelines from the Korean Diabetes Association to compare the glucose control in those groups, with a cross-sectional design, multivariable logistic regression, and glycosylated hemoglobin <6.5% as the reference.
Results
Overweight males aged ≥60 years had a high odds ratio (OR) for degraded glucose control (OR, 1.706; 95% confidence interval [CI], 1.151 to 2.527). Among obese females, those in the ≥60 years age group showed an increased OR for uncontrolled diabetes (OR, 1.516; 95% CI, 1.025 to 1.892). Moreover, in females, the OR for uncontrolled diabetes tended to increase as the BMI increased (P= 0.017).
Conclusion
Obesity is associated with uncontrolled diabetes in female patients with diabetes who are aged ≥60 years. Physicians should closely monitor this group for diabetes control.
