Subjects
The children who volunteered for the study were all over 10 years old. They either had participated in the Obesity Camp for Adolescents in 2004 offered by the Department of Pediatrics, Soonchunhyang University Hospital, or were friends of the camp participants or children of the hospital staff. Written informed consent was obtained from the parents or guardians of all children. Any systemic disease or medication history was ruled out by history and physical examination. After the children
Results
Clinical characteristics were not different, other than the weight and BMI, between the overweight group and the normal-weight group (Table I). The results of echocardiographic measurement are shown in Table II. LV geometry and systolic function, LVDd, diastolic interventricular septal thickness, and LVMI were significantly increased in the overweight group. In total, there were 5 cases of eccentric hypertrophy, 1 case of concentric hypertrophy, and 3 cases of concentric remodeling. Among the 3
Discussion
In the evaluation of diastolic function, the tissue Doppler test showed a difference between the two groups, whereas the mitral valve inflow Doppler tests displayed none. These results are similar to those of the study by Mehta et al,16 which examined the diastolic function of obese children with the average age of 14.4 years. In this study, peak E velocity was higher in the overweight group, which opposes previous results of studies for cardiac diastolic function in obese adults17, 18;

Assessment of left ventricular mass index could predict metabolic syndrome in obese children
2016, Journal of the Saudi Heart AssociationCitation Excerpt :Mehta et al. used TDE to measure the diastolic function in obese children, and revealed impaired diastolic function [29]. Other studies using TDE to assess the effects of childhood obesity on diastolic function have reported similar findings [24,25,30,31]. In this study, the LVMI in obese children was significantly higher when compared to control group and also more significant in MS obese children when compared to non-MS obese children.
Childhood obesity and cardiovascular dysfunction
2013, Journal of the American College of CardiologyCitation Excerpt :However, the relevance of these factors during childhood obesity remains to be determined. It has been proposed that the duration of obesity is a major factor that determines the likelihood of developing systolic dysfunction and heart failure (14). Indeed obesity in older individuals appears to pose less of a mortality risk than it does in younger subjects (117).
