CONCLUSION 1. Physical development of children in the
oil and gas region is lower compared to the con-
trol group. The children are significantly more
often have disharmonious physical development
in the form of a deficiency in body weight and a
decrease in average growth rates.
2. Indicators of bone metabolism, such
as: osteocalcin, PTH in children of the oil and gas
region, are reduced, when compared with the
control group.
3. The levels of calcium and phosphorus
in the blood serum in the comparative aspect are
not changed.
4. The indicator characterizing the ratio of
the processes P1NP / -Crosslaps, bone remodel-
ing was almost 2 times lower in children of the
main group (p = 0.039). It may indicate a relative
prevalence of resorptive processes over synthetic
in bone tissue in children of the oil and gas re-
gion, especially groups of 16-18 years old, which
indicates a weakening of the activity of bone tis-
sue remodeling, which may be due to impaired
regulation of mineral metabolism.
