Predictors of Prediabetes Among Communities Without a Family History of Type 2 Diabetes Mellitus: A Case-Control Study

Background Prediabetes is the golden period to promote, prevent, or delay diabetes mellitus (DM) conversion. This study aims to assess the risk predictors associated with prediabetes among communities without a family history of type 2 DM (T2DM). Methodology This case-control study involved 570 participants (265 prediabetes cases and the same number of age-matched controls) in Palembang, Indonesia. Each participant is willing to take fasting blood glucose, lipid profile tests, and physical examinations. Results Multivariate analysis of this study revealed that significant risk predictors identified were occupation in the informal sector (aOR = 3.28; 95% CI = 1.64-6.58; p-value = 0.001), diastolic blood pressure of 80-89 mmHg (aOR = 2.18; 95% CI = 1.35-3.52; p-value = 0.001), diastolic blood pressure of 90-99 mmHg (aOR = 2.09; 95% CI= 1.15-3.82; p-value = 0.016), with an aOR = 5.80 (95% CI= 3.71-9.05; p-value <0.001). triglyceride-glucose index was the dominant risk predictor for prediabetes. Conclusions Knowing who is most vulnerable can guide the efficient allocation of promotion and prevention resources. This finding proves essential consideration for health promoters emphasizing a healthy diet and lifestyle by maintaining diastolic pressure and triglyceride glucose (TyG) index while considering the occupation in populations without a family history of T2DM.
