OBJECTIVE: Diabetes mellitus is a non-communicable disease (NCD) with metabolic dysfunction that has attained epidemic proportions worldwide. Vascular complications account for the mortality and morbidity associated with diabetes. Hence, the study aimed to estimate the prevalence and risk factors for vascular complications in patients with type 2 diabetes mellitus (T2DM).

PATIENTS AND METHODS: A cross-sectional national multistage survey, the Saudi Health Interview Survey (SHIS), was used in this study, which surveyed individuals aged 15 years or older. After inclusion and exclusion criteria, 1240 diabetic patients’ data were analyzed for sociodemographic data, risk factors, and prevalence of micro and macrovascular complications. Binary logistic regression with stepwise backward elimination was performed to build the optimal model to assess the determinants of macrovascular complications in diabetic patients. The strength of the associations was examined by estimating adjusted odds ratios (aOR) with their 95% CI. p-value < 0.05 was considered statistically significant. R Studio Version 1.2.1093 was used for statistical analysis

RESULTS: Prevalence of micro and macrovascular complications in the diabetic patients was 6.05%, in which 3.5% had myocardial infarction, 1.2% had stroke and 1.9% had renal failure. The optimal model showed that for each year increase in age (aOR=1.05, 95%CI 1.02-1.07; p-value=0.000), smoking history (aOR=4.02, 95%CI 2.23-7.26; p-value=0.000), hypertensive patients (aOR=2.71, 95%CI 1.47-4.99; p-value=0.001), patients with low physical activity (aOR=4.32, 95%CI 1.26-14.82; p-value=0.001) were more likely to develop macro and microvascular complications in diabetic patients.

CONCLUSIONS: The high prevalence of microvascular and macrovascular complications in diabetic patients poses a serious threat to public health in Saudi Arabia. A multisectoral approach needs to be undertaken to properly control and modify common risk factors at the community level.
