The aim of the study was to examine the relationships between vitamin D status and metabolic complications. Material and Methods The results of blood pressure measurements, biochemical tests and ultrasound of the liver were compared in both groups. The study was conducted at the Children’s University Hospital in Krakow, Poland. 30 obese adolescents (mean 13.23y.o.); 18 with 25OHD levels 20 ng/mL. Results The vitamin D deficient group presented with significantly higher values of the diastolic blood pressure (125.9vs.115mmHg), uric acid level (384.7vs.301.5umol/L) and lower phosphorus level (1.4vs.1.65mmol/L), higher prevalence of arterial hypertension (44vs.8.3%), and liver steatosis (25vs.8.3%); lower, but not significantly, levels of fibroblast growth factor 23 and fibroblast growth factor 19. Conclusions Hypovitaminosis D in obese adolescents is associated with higher prevalence of arterial hypertension, liver steatosis, elevated serum uric acid and low phosphorus levels. The potential contribution of the fibroblast growth factor 23 and fibroblast growth factor 19 in these complications development needs further investigation.
