stage between normal people and patients with type 2 diabetes mellitus. The pathogenesis is mainly related to insulin resistance (IR). The relationship between IR and hypertension is a complex and multifactorial phenomenon. We examined the prevalence of IR in prediabetic patients with hypertension. Objectives: The present study aimed to determine the incidence of IR according to the HOMA2 model in the group of prediabetes with hypertension, compared with the group of prediabetes without hypertension. Subjects and Methods: The cross-sectional study described and collected data from 191 people with prediabetes from February 2023 to September 2023 at the Examination Department of Cho Ray Hospital. IR was determined by the HOMA2 calculator, using a threshold of 1.29 for IR. Prediabetes and hypertension were diagnosed according to ADA 2022 and ISH 2020 criteria, respectively. Results: The number of subjects selected to analyze the data was 179 patients, including 89 prediabetes patients without hypertension and 90 prediabetes patients with hypertension. The prevalence of IR in the overall prediabetes group was 56.9%. The prevalence of IR in the hypertensive group was 66.7%, higher than the non-hypertensive group at 47.2%, which was statistically significantly different. The values of the index in HOMA2 did not differ statistically significantly between non-hypertensive and hypertensive populations. Conclusions: The prevalence of IR in prediabetes patients with hypertension was 66.7%, greater than the prediabetes patients without hypertension of 47.2%, P = 0.013. Attention should be paid to good control of blood pressure in patients with prediabetes.
