In 2020, statistics from Lopburi healthcare data, 9.1 percent of Thaluang hospital’s patients had Type 2 diabetes, the most significant number among the other diseases in Thaluang hospital. We conducted this research to study the prevalence and associated factors of type 2 diabetes vascular complications, which can be used to promote the prevention of this complication in the future. We conducted this cross-sectional analytic research using the secondary data from Thaluang hospital’s medical record to assess the prevalence and the associated factors of vascular complications in type 2 diabetes patients in Thaluang hospital. From Multivariate analysis, we found the statistically associated factors of each vascular complication. Ischemic heart disease is associated with age (Odds ratio 1.09 (1.03-1.16) p-value 0.01), and HbA1C more than 8.5 g/dl (Odds ratio 6.38 (1.45-28.13) p-value 0.01). Stroke is age (Odds ratio 1.02 (1.01-1.04) p-value 0.03), hypertension (Odds ratio 3.26 (1.02-5.16) p-value 0.04), and Calcium channel blocker use (Odds ratio 1.76 (1.12-2.79) p-value 0.02). Peripheral artery disease is associated with age (Odds ratio 1.03 (1.01-1.05) p-value <0.01), female gender (Odds ratio 1.52(1.06-2.48) p-value 0.03), duration since diagnosis more than five years (Odds ratio 2.11(1.40-3.20) p-value <0.01), Insulin use (Odds ratio 2.17(1.36-3.46) p-value <0.01). Diabetic retinopathy is associated with duration since diagnosed more than five years (Odds ratio 2.49(1.58-3.93) p-value 0.04), and HbA1C more than 7.5 g/dl (Odds ratio 3.634(1.47-8.99) p-value 0.01). Peripheral neuropathy is associated with age (Odds ratio 1.06 (1.01-1.11) p-value 0.01), duration since diagnosis (Odds ratio 1.16(1.01-1.33) p-value 0.03), and HbA1C (Odds ratio 1.40(1.12-1.75) p-value <0.01). Chronic kidney disease is associated with age (Odds ratio 1.02 (1.01-1.04) p-value 0.02), ACEI/ARB use (Odds ratio 2.53(1.65-3.88) p-value <0.01), and HbA1C greater than9.0 (Odds ratio 1.69 (1.08-2.67) p-value 0.02).
