<![CDATA[Background: Excess body weight is common in type 2 diabetes mellitus (T2DM) and may influence treatment selection, but BMI profiles by antidiabetic regimen complexity remain underexplored in Indonesian hospital settings.Objectives: This study aimed to describe BMI profiles across antidiabetic regimen complexity among patients with T2DM in Indonesia.Methods: This multicenter cross-sectional study used secondary hospital-based data from 628 adult patients with T2DM from three Indonesian study sites in Jakarta, Bali, and Mataram. Patients were identified using ICD-10 codes E11.0-E11.9. BMI was categorized using Asian cut-off points, and antidiabetic regimens were classified according to the number of documented drug classes. Descriptive analyses summarized BMI and regimen patterns. One-way ANOVA compared mean BMI across regimen complexity groups, while chi-square and linear-by-linear association tests examined obesity grade distribution.Results: The mean age was 59.02 ± 11.34 years, and mean BMI was 25.72 ± 4.20 kg/m². Overall, 352 patients (56.1%) were obese. Monotherapy was the most common regimen complexity group (57.5%), followed by dual therapy (30.4%), triple therapy (10.0%), and ≥4 drug classes (1.0%). Mean BMI differed significantly across regimen complexity groups (p=0.025), and obesity grade showed an ordinal trend across increasing numbers of documented antidiabetic drug classes (p=0.017).Conclusion: Obesity was common among patients with T2DM in this secondary hospital-based dataset. Given the cross-sectional design, the observed association between higher numbers of documented antidiabetic drug classes and less favorable BMI profiles should not be interpreted as causal or as reflecting disease severity or therapeutic intensity.]]>
