Objective: Determination of changes in metabolic status and vitamin D, osteoprotegerin concentrations in obese children.
Methods: We examined 212 children in the University Hospital from 2016 to 2018 yrs. Their anthropometric parameters (body mass index (BMI)) were determined. Blood levels of vitamin D, OPG, insulin were determined. In the biochemical blood test, the parameters of uric acid, glucose were evaluated. All children were divided into 2 groups: group 1 children with morbid obesity - 140 patients (90 boys(B)/50 girls(G)) (BMI more than 99th percentile for sex and age) (BMI 33.04±4.67 kg/m2, age 14.17±2.42years); group 2 - 72 patients (B/G=34/38) with alimentary obesity (BMI-95-99th percentile for sex and age) (BMI 27.60±2.06 kg/m2, age 14.43±2.27years). The control group consisted of 83 patients (B/G=43/40) with normal body weight (BMI 19.86±2.24 kg/m2, age 14.32±2.30years).
Results: In the subgroups of boys with obesity, there were significant differences in the concentration of uric acid in comparison with the control (alimentary obesity 424.10±65.25 mmol/l vs 242.58±49.90 mmol/l (P=0.01)), morbid obesity 324.10±59.33 mmol/l vs 242.58±49.90 mmol/l (P=0.01)). In boys with obesity higher concentrations of OPG were detected relative to the control group (alimentary obesity 21.89±2.17 ng/ml vs 18.1±1.21 ng/ml (P=0.05), morbid 22.22±2.14 ng/ml vs 18.1±1.21 ng/ml (P=0.03)). In the obese boys, the level of vitamin D is significantly lower than in the control group (alimentary obesity 29.56±6.01 ng/ml vs 33.02±4.10 ng/ml (P=0.05), morbid obesity 27.56±5.75 ng/ml vs 33.02±4.10 ng/ml (P=0.05)). Obese girls showed a significant decrease in vitamin D relative to the control group (alimentary obesity 24.21±10.75 ng/ml vs 31.34±7.35 ng/ml (P=0.05), morbid obesity 23.52±4,18 ng/ml vs 31.34±7.35 ng/ml (P=0.04)). In boys with obesity higher concentrations of insulin were detected relative to the control group (alimentary obesity 18.9±12.7 μU/ml vs 9.1±4.2 μU/ml (P=0.0001), morbid 28.71±7.36 μU/ml vs 9.1±4.2 μU/ml (P=0.001)). In girls with obesity, the concentration of insulin relative to the control group was (alimentary obesity 20.28±6.25 μU/ml vs 14.10±6.80 μU/ml (P=0.001)) morbid obesity 23.32±9.65 μE/ml vs 14.10±6.80 μU/ml (P=0.001)).
Conclusion: Children with obesity have a significant decrease in the concentration of vitamin D. There is an increase in insulin and OPG rates.
