Evaluation of Total Homocysteine Levels in Relation to Abdominal Fat Mass and Traditional Cardiovascular Risk Factors...

Cardiovascular diseases remain the leading cause of mortality worldwide, with multiple risk factors contributing to their development. Among these, obesity and hyperhomocysteinemia have been recognized as significant contributors to endothelial dysfunction, a key early event in the pathogenesis of atherosclerosis. Our study aimed to evaluate the relationship between total homocysteine (tHcy) levels and traditional cardiovascular risk factors in overweight and obese adolescents. We enrolled 42 obese, 14 overweight, and 25 non-obese children. No significant differences in tHcy levels were observed between overweight, obese, and non-obese adolescents. Homocysteine positively correlated with age (r = 0.433, p < 0.011) and creatinine concentrations (r = 0.363, p = 0.001) in the overall group of overweight, obese, and non-obese children, as well as in the combined group of overweight and obese children (for age: r = 0.275, p = 0.025; for creatinine: r = 0.278, p = 0.025). We did not find any association between homocysteine and atherogenic lipid profile, insulin-resistance status, blood pressure, and inflammatory parameters in overweight and obese patients. Age emerged as the strongest independent predictor of homocysteine levels. The observed association with creatine suggests a potential renal contribution to homocysteine metabolism.
