Objective: To determine the prevalence of stroke and its risk factors in Thai diabetic patients who attended the diabetes clinics of university and tertiary-care hospitals.
Material and Method: A cross-sectional, multi-center, hospital-based diabetes registry was carried out at diabetes clinics of 11 university and tertiary-care hospitals. Demographic data, clinical characteristics, common drugs used and laboratory parameters were analyzed for prevalence and risk factors associated with stroke.
Results: The prevalence of stroke in the patients studied was 3.5%. Most of the patients were type 2 diabetes and had ischemic stroke. One of the risk factors associated with stroke was age greater than 60 years, and the risk appeared to be highest if the patients’ age was greater than 70 years (adjust OR = 3.29, p = 0.012). Other risk factors included male sex, systolic blood pressure of > 140 mmHg, use of oral hypoglycemic agents, lipid lowering agents and aspirin. There was no association between stroke and duration of diabetes, occupation, educational level, BMI, smoking, alcohol drinking, diastolic blood pressure, use of antihypertensive drugs or insulin, glycemic control, lipid profiles and kidney function.
Conclusion: Ischemic stroke was common among Thai patients with diabetes especially in the elderly. The present result emphasizes the relationship between level of systolic blood pressure and the occurrence of stroke. Optimal blood pressure control should be underscored in caring for diabetic patients.
