TG=triglycerides, HDL-C= high density lipoproteins cholesterol, LDL-C= low density lipoproteins cholesterol, SBP=systolic blood pressure

DBP= diastolic blood pressure, ref.= reference, DXA VAT= dual x-ray absorptiometry visceral adipose tissue

TFM = Total fat mass, CT VAT = computed tomography visceral adipose tissue

^*other covariates included within this final model are not presented

DXA models: LDL-C = Tanner stage; SBP = Tanner stage, Sex, Race; DBP = Tanner stage, Age

CT models: LDL-C = Race, Age; SBP = Tanner stage, Age, Sex, Race; DBP = Tanner stage, Age
