Diagnostic Performance of HbA1c for Detecting OGTT-Diagnosed Diabetes in Obese Individuals with Suspected Prediabetes.

ABSTRACT: Background: We aimed to investigate the diagnostic performance between the oral glucose tolerance test (OGTT) and HbA1c in diagnosing prediabetes and diabetes among obese individuals, and to evaluate the diagnostic performance of HbA1c for detecting OGTT-defined diabetes in obese individuals referred for evaluation of suspected prediabetes. Methods: Individuals with prediabetes were included between 1 January 2020 and 31 December 2022. Participants were categorized as mildly, moderately, morbidly, or super obese based on body mass index (BMI). According to the 75 g OGTT results, patients were classified into three groups: isolated impaired fasting glucose (IFG), combined IFG + impaired glucose tolerance (IGT), and overt type 2 diabetes mellitus (T2DM). The threshold HbA1c val
