The FRS items include age, gender, total cholesterol, high density lipoprotein cholesterol (HDL-C), systolic blood pressure, status of diabetes and smoking. Methods: This cross-sectional study was conducted on 1025 male military personnel in 2022. For comparative analysis, ANOVA or t-test, as well as the Chi-square (or Fisher's exact) test was used. All statistical analyses were conducted using SPSS 22 software. The statistical significance level was set at 0.05. Results: The prevalence of hypertension was 2.3 % and increased with age. The prevalence of overweight and obesity increased with age and was 54.7% as well as 14.1%, respectively, in those 40- 45 years of age. Diabetes affected 6.2% of the oldest group and 8.2% of participants aged 40–45 years. TC was increased in one-third of understudied cases. The percentage of abnormal LDL-C was 57.5%. These results were accompanied by increased TG in 34.6%, low HDL-C in 36.4%, and FPG >100 mg/dl in 13.2% of subjects. Out of a total of 608 participants over 30 years of old, a low FRS (<10%) was calculated for 571 (93.9%), the others, were classified as moderate (5.6%) and high (0.5%) risk. The prevalence of hypertension among the high and moderate FRS risk group was higher than low-risk group older persons have a higher 10- year CVD risk level (p < 0.001). The level of, blood pressure, FPG, LDL, TC, and TG, in the high-risk group, was significantly higher than in the two other groups (P=0.001). Conclusion: Although a high proportion of military personnel had a low risk of CVD in the next 10 years, the high prevalence of overweight and other risk factors such as LDL level needs special attention. https://jbe.tums.ac.ir/index.php/jbe/article/view/1614
