Table 3 Odds ratio for elevated liver enzymes and sonographic fatty liver according to the number of the metabolic syndrome components and categories of body mass index before and after adjustment for age

From: Association of the components of the metabolic syndrome with non- alcoholic fatty liver disease among normal-weight, overweight and obese children and adolescents

Variables Participants n (%) total:1110   Unadjusted for age OR (95% CI) Adjust ed for age OR (95% CI)
   Participants who underwent sonogrphy n (%) total: 931 Elevated ALT Elevated AST Elevated ALP Fatty liver Elevated ALT Elevated AST Elevated ALP Fatty liver

  1. : The ORs (95% CIs) were calculated by performing logistic regression analysis to determine the risk of elevated ALT according to the number of components of the metabolic syndrome after adjustment for age and body mass index.
  2. P value < 0.05; ** P value < 0.01
