Background: Metabolic syndrome (MS) present in type 2 diabetic and hypertensive patients greatly increases the risk of strokes and cardiovascular diseases. Timely detection of MS facilitates appropriate preventive and therapeutic approaches to minimize these risks. Our study aimed to determine the prevalence of MS among Yemeni type 2 diabetic and hypertensive patients using AHA/NHLBI definition. Methods: This study was a cross-sectional study conducted from April 2018 to June 2018. A total of 168 of patients with type 2 Diabetes, hypertensive, and DM type 2 with hypertensive were selected from the various out-patient departments of Al-thawra hospital and hospital of university of sciences and technology in Sana'a, Yemen. Components of MS were collected for these patients. The data was analyzed in order to identify prevalence of MS in these patients. Statistical analysis included usage of Chi-square tests using the software package SPSS 21.0. Results: The total prevalence of MS among the study patientswas81.0% and the prevalence increased with the age; 59.3 of patients were aged up 50 years old. The prevalence of MS among patients with diabetes type 2 was 75.9 of all total MS. Moreover, its prevalence in hypertensive patients as compared to non-hypertensive was 87.5%. The highest prevalence was observed among patients with both hypertensive and diabetes type 2. Conclusions: The prevalence of MS among Yemeni type 2 diabetic and hypertensive patients was very high and it is associated with increased morbidity and mortality. This emphasizes the need for more attention to investigate this condition to decreasing the prevalence of cardiovascular morbidity and mortality in these patients.
