RESULTS AND DISCUSSION The level and harmony of physical status
according to the results of a comprehensive as-
sessment of health status were determined in
519 adolescents in grades 7-11 (boys –
275,
girls
–
244).
Of these, 349 (boys –
186,
girls –
163)
are schoolchildren of the main group (Kenkiyak)
and 170 (boys –
89,
girls –
81)
adolescents in the
control group (Kobdy).
The results of the examination for the level
and harmony of physical development are pre-
sented in table 1.
The presented data indicate that normal
physical development in the main group took
place only in 48.4% of children, the remaining
51.6% were underweight or deficient in weight
and height, 4% were overweight. All of them
were classified as disharmonious development. At
the same time, in 16 children, despite the fact
that weight and height parameters corresponded
to age norms, development was also disharmo-
nious. In general, 43.8% of children had normal,
harmonious development, 56.2% –
disharmonio-
us. Among children with disharmonious develop-
ment, children with a lack of weight predomi-
nated, mainly boys (table 3).
In the comparison group, 68.8% of chil-
dren had normal physical development, the re-
maining 31.2% were underweight or deficient in
weight and height, and 4.7% were overweight.
All these children were classified as disharmoni-
ous development, while only 4 children (2.4%),
despite the fact that weight and height parame-
ters corresponded to age norms, development
was also disharmonious. On the whole, 66.5% of
children had normal, harmonious development,
33.5%
–
disharmonious.
Thus, in the main group of children living
in the oil and gas region, their physical develop-
ment is much worse than in the control group.
56.2% had a disharmonious development.
In recent years, more and more attention
has been paid to laboratory research methods
that allow a quick and accurate assessment of
bone metabolism.
It has been proven that biochemical mark-
ers allow early diagnosis of signs of bone loss and
thereby predict the risk of fractures; the in forma-
tiveness of markers was revealed for assessing
the effectiveness of various methods of prevent-
ing osteoporosis. The reference values of the in-
dicators can differ significantly depending on
