Objectives: An increase in left ventricular mass (LVM), a determinant of left ventricular hypertrophy (LVH) in adults and children, is a major risk factor for cardiovascular morbidity and mortality. This study evaluated LVM in athletes, healthy and obese children. Materials and Methods: The study included 260 children aged 9-17.8 years (170 males, 90 females). No participants had diseases such as aortic pathologies, hypertension, or hypertrophic cardiomyopathy. The participants were divided into three groups: Group 1, athletes (n=89); Group 2, control (n=87); Group 3, obesity (n=84). Obese athletes were excluded from the study. The participants were further divided into the preadolescent group (n=72, aged 9-11.91 years) and the adolescent group (n=188, aged 12-17.8 years). LVM, LVM index (LVMI) were calculated using the M-mode echocardiography. Results: The mean LVMI for all participants was 32.72±8.48 g/m2.7. The cut-off value of 42.76 g/m2.7, which was the 95th percentile for the control group LVMI value, was taken as the LVH criterion. There was a significant difference between Group 1-3 and Group 2-3 in terms of LVMI. Conclusion: Because of obesity and accompanying comorbid diseases in children have increased recently, being informed about the presence of LVH is critical for the diagnosis of cardiovascular diseases that may cause morbidity in childhood and young adulthood, and for early treatment planning.
