In Iran limited number of studies have been performed on military personnel and their CV-risk. We aimed to investigate correlation between obesity and cardiovascular disease (CVD) risk factors in military personnel. Methods: The present cross-sectional analytical study, analyzed the data of 559 military personnel in Tehran, Iran in 2023. The dataset sourced from the registry system. The biochemical analysis of blood samples was performed by a biomedical analysis company. The univariate regression analyses were conducted through separate univariate linear regression within the obesity group. Results: The mean age of personnel was 36.58 years. Among obese personel, there was an inverse relationship between age and cholesterol β=-0.11. Moreover, hemoglobin β=-0.68 and MCH β=-0.33 were significantly related to high cholesterol, MCH is associated with risk of metabolic syndrome (β=-0.57). Moreover among obese personnel, lower uric acid levels and higher ALT levels are correlated with an increased risk of Diabetes. Conclusion: The prevalence of obesity in military personnel was the same as in the general population. Diabetes, hyperlipidemia, high blood pressure, obesity, and metabolic syndrome were all linked to CVD risk factors among military personnel. Although the prevalence of metabolic syndrome in military personnel was lower than their peers in other countries, other risk factors of CVD were prevalent among military personnel. https://ijph.tums.ac.ir/index.php/ijph/article/view/34198 https://ijph.tums.ac.ir/index.php/ijph/article/download/34198/8451
