Trends in the adjusted prevalence of suspected NAFLD (overweight plus ALT >25.8 U/L for boys and >22.1 U/ L for girls), the prevalence of high waist circumference (>90th sex and age percentile), and mean BMI z-score among A, obese female and B, obese male adolescents in the NHANES III through NHANES 2007–2010. Estimates were adjusted for age and race/ethnicity. P for linear trend was <.0001 for the prevalence of NAFLD in both males and female and for the prevalence of high waist circumference among females. Trends in BMI z-score were not significant for either males or females.
