Clinical Trial Summary

Prevalence rates of childhood obesity have reached alarming levels. As childhood obesity may already be associated with serious comorbidities, obese adolescents are at significantly higher risk for obesity and increased morbidity and mortality during adulthood. Combined lifestyle interventions, which include regular physical activity and dietary restriction, have been shown to result in most significant improvements in cardiovascular function and their associated factors in the pediatric and adolescent population with obesity. The aim of this study is to investigate the effects of a combined exercise and diet intervention on cardiovascular function and their associated factors in obese children.


Clinical Trial Description

Sixty obese children and adolescents will complete a 6-week program of exercise and diet intervention. Thirty normal-weight children and adolescents will be recruited as control group. Clinical characteristics, body composition, blood biochemistry, and circulating irisin levels of the subjects will be measured before and after 6-week intervention. Endothelial function will be assessed by a flow-mediated dilation test. Circulating exosome-derived miRNAs, exercise-induced epigenetic modifications, circulating irisin levels irisin concentration in plasma and arterial stiffness as well as cardiac autonomic function will be investigated before and after the 6-week intervention. Fecal samples were collected before and after the 6-week intervention for analysis of the compositional and functional changes in the human gut microbiota. ;
