Effects of comprehensive intervention on glucose and lipid metabolism, liver and kidney function and cardiovascular function in obese adolescents

Objective To investigate the effects of exercise combined with dietary intervention on glucose and lipid metabolism, liver and kidney function and cardiovascular function in obese adolescents. Methods Seventy-one obese adolescents were enrolled in this study. Six weeks of exercise combined with dietary intervention were performed to determine anthropometry, glucose and lipid metabolism, liver and kidney function and cardiovascular function before and after intervention. Results After 6 weeks of comprehensive intervention, in addition to significant improvement in anthropometry indicators, fasting insulin [ (18.76±11.46 vs 11.32±6.54) uU/L], LDL-C [ (2.96±0.69 vs 2.22±0.62) mmol/L], TG [ (1.57±0.82 vs 0.89±0.37) mmol/L] and TC [ (4.52±0.76 vs 3.53±0.62) mmol/L] decreased significantly and insulin resistance improved significantly. AST [ (36.1±32.28 vs 22.89±7.27) U/L], ALT [ (57.42±61.25 vs 27.86±22.12) U/L], blood urea nitrogen [ (4.78±0.89 vs 3.44±0.79) mmol/L] and uric acid [ (498.83±120.6 vs 471.07±120.96) mmol/L] were significantly decreased and the detection rates of fatty liver and kidney were significantly decreased (P<0.05), RHI (1.34±0.28 vs 1.69±0.45) and nitric oxide/endothelin-1 (ET-1) (1.69±0.41 vs 2.67±0.86) significantly increased and atherogenic index (3.06±0.96 vs 2.58±0.80) significantly decreased (P<0.01). Conclusion The comprehensive intervention of exercise combined with diet can effectively improve anthropometry indicators, glycolipid metabolism, liver and kidney function as well as cardiovascular function of obese adolescents.
