Abstract

Introduction: Some studies have shown that echocardiographic findings are associated with obesity, accompanied by an increase in the left ventricle's size, diameter, and weight. This study compared Tissue Doppler and Pulse Doppler echocardiographic changes among obese children and adolescents and individuals of average weight.

Method: In 2021, this research was conducted on 66 children and adolescents aged 9 to 18 in Birjand. It included 33 individuals, comprised of 25 boys and eight girls, with a Body Mass Index (BMI) greater than 95, classified as the obese group, and 33 individuals, comprised of 21 boys and 12 girls with a BMI between 10 and 85, ranked as the control group. The echocardiographic parameters of the two groups were measured, and SPSS version 16 was used to analyze the data at a significance level of less than 0.05.

Result: In the control group, the average 12.87±2.87years, whereas in the obese group, the average age was12.84±1.92. In the obese group, the mean values of the parameters S´, A', and A were12.91±2.63, 12.61±2.75 and 74.83±16.75, while in the control group, they were11.47±2.66, 10.28±2.72, and 63.21±15.41. The obese group had substantially higher values compared to the control group (P<0.05). The mean values of IVRT, IVCT, MPI, E', and E were more significant in the obese group than in the control group, whereas ET and E/A were more significant in the control group. These differences, however, were not statistically significant.

Conclusion: Several echocardiographic parameters of obese children and adolescents differ from those of the control group. These differences may indicate that obese infants and adolescents have impaired diastolic function.
