Prevalence of Prediabetes and Associated Risk Factor Assessment Among Urban Adult Population in North Bihar, India

Background: Type 2 Diabetes Mellitus (T2DM) and Impaired Glucose Tolerance (IGT) are major public health concerns globally, with increasing prevalence in India. The study assessed the prevalence of T2DM and IGT among, and to recognize key associated risk factors. Methods: 1050 persons were involved in the study selected by rigorous random sampling. To diagnose T2DM and IGT, data were gathered via in-person interviews using a pre-made questionnaire, which were then followed by clinical exams and blood testing. Results: The incidence of IGT was 12.48% and T2DM was 9.24%, respectively. In the 61–70 age range, the highest incidence of T2DM (20.86%) and IGT (21.58%) was noted. The incidence of T2DM was somewhat higher in men (9.87%) than in women (8.58%). The incidence rates of T2DM (21.84%) and IGT (36.78%) were considerably greater in those with a positive family record of diabetes. Additionally, there was a substantial correlation found between obesity and hypertension and a higher incidence of T2DM and IGT. Conclusion: The study reveals a considerable incidence of T2DM and IGT in the Sharifganj area of Katihar, with advanced age, male gender, family history of diabetes, obesity, and hypertension identified as key risk factors. Recommendations: Targeted public health interventions, including lifestyle modifications, regular screenings, and health education, are essential to manage and reduce the risk of diabetes in this community.
