Multivariate analyses demonstrated that overweight or obesity was an independent predictor of ALT testing in young people (ages 18-25) but not in children (ages 10-17) and of abnormal test results in all CYP, irrespective of ALT threshold.
There was no association between liver enzymes and FPG either in the underweight group or in the normal weight group; however, a significant correlation was observed in the overweight or obesity group (alanine transaminase (ALT), p<0.01; aspartate aminotransferase (AST), p<0.05).
In multivariate linear regression analysis, alanine aminotransferase was significantly and positively associated with circulating zonulin levels in adolescents with overweight or obesity (P < 0.01) after controlling for the effect of potential confounding factors.
