Cardiometabolic implications of triglyceride–glucose index, remnant cholesterol, and vitamin D in normoglycemic Arab adolescents: a cross-sectional study

TyG and RC are associated with VDD and cardiometabolic risks in normoglycemic adolescents, particularly in boys. Sexual dimorphisms were evident, with boys showing higher TyG index and VD levels, while girls had higher RC values. The TyG index was associated with hypertension and VDD in boys while linked to obesity and low HDL-C in girls. VD is inversely correlated with these risks, which warranting confirmation via randomized trials.
