COMPARATIVE CHARACTERISTICS OF AGE CHARACTERISTICS OF MORPHOMETRIC PARAMETERS OF DIFFERENT PARTS OF THE SPINAL COLUMN IN GIRLS AND BOYS AGED13 TO 16 YEARS
Abstract:
Objects of the study: healthy girls and boys from 13 to 16years old, pupils of the school number 278 of the Almazar district of Tashkent. In total there were examined 111 girls and 89 boys aged 13 to 16.
The obtained data was subjected to statistical processing on a Pentium IV computer, using the Microsoft Office Excel 2007 software package, including the use of built-in statistical processing functions.
The rate of growth in girls aged 13 to 16 years increased 1.16 times and amonh boys 1.24 times. The size of the cervical spine in girls aged 13 to 16 years increases by 1.20 times and among boys 1.29 times; the length of the thoracic spine in girls aged 13 to 16 increases 1.14 times and in boys 1.21 times, the length of the lumbar region for girls increases 1.14 times for boys 1.16 times and the length of the sacrococcygeal department in girls is increased by 1.21 times for boys 1.29 times.
The rate of increase in the length of the spine in boys aged 13 to 16 years is more intense than in girls of the same age.
Keywords:
Age features of morphometric indices of different parts of the spinal column in girls aged 13 to 16 years.
Urgency: The problem of spinal column among young generation can be considered as a serious public issue in the worcforce and leads to face difficulties in professional activities. In addition, growth rate in the spinal column develops in childhood, adolescense and slows down as individual getting older. Albeit, the solutions and scientific works in that area have not been achieved sufficiently. Thus, the following pape has been conducted in that medical area. The cross sectional study has been carried out about spinal growth rate among school children, particularly the data was taken from both genders.
The anthropometric measurements are considered as age dynamics, genders, visual inspection of the deformity of the vertebral column and others.
The purpose of the study: To study the age features of the morphometric indices of various parts of the spinal column in children and adolescents.

The total length of the spinal column of14 years old male ranges from 52.56 cm to 61.2 cm, averaging 56.54 ± 3.02 cm. The length of the cervical region varied from 6.36 cm to 7.4 cm, in average of 6, 84 ± 0.29 cm. The length of the thoracic region was in the range from 27.28 cm to 31.76 cm, on aver-
age 29.34 ± 1.67 cm. The length of the lumbar spine varies from 9.93 cm to 11, 57 cm, on average of 10.68 ± 0.55 cm. The length of the sacrococcygeal region varied from 8.98 cm to 10.46 cm, on average of 9.67 ± 0.53 cm.

The total length of the spinal column of15 years old female ranges from 54.8 cm to 61.92 cm, averaging 63.6 ± 3.43 cm. The length of the cervical region varied from 6.90 cm to 8.92 cm, on average 8.02 ± 0.43 cm. The length of the thoracic part was
in the range from 27.95 cm to 36.1 cm, on average of32.45 cm. The length of the lumbar spine varies from 10.2 cm to 13.17 cm, on average of 11.83 ± 0.54 cm. The length of the sacrococcygeal part varied from 9.8 cm to 12.7 cm, on average 11.38 ± 0.56 cm.

The total length of the spinal column of 15 years old male varies from 58.8 cm to 76 cm, on average of 65.8 ± 3.83 cm. The length of the cervical region varied from 7.40 cm to 9.58 cm, on average of 8.29 ± 0.43 cm. The length of the thoracic region was in the range from 29.9 cm to 38.76 cm, on average of 33.55 cm. The length of the lumbar spine varies from 10.94 cm to 14.14 cm, on average of 12.24 ± 0.54 cm. The length of the sacrococcygeal part varied from 10.52 cm to 13.60 cm, on average of 11.78 ± 0.56 cm.
The total length of the vertebral column among 16 years old female ranges from 58 cm to 69.2 cm, on average 64.74 ± ± 3.82 cm. The length of the cervical region ranged from 7.31 cm to 8.72 cm, on average, 8.16 ± 0.39 cm. The length of the thoracic region was in the range from 29.58 cm to 35.29 cm, on average 33 ± 0.32 cm. The length of the lumbar spine varies from 10.78 cm to 12.87 cm, on average of 12.04 ± 0.56 cm. The length of the sacrococcygeal part varied from 10.38 cm to 12.39 cm, on average of 11.58 ± 0.65 cm.
The total length of the vertebral column among 16 years old male pupils ranges from 63.2 cm to 74.0 cm, averaging 68.29 ± 3.82 cm. The length of the cervical region ranged from 7.96 cm to 9.32 cm, on average of 8.6 ± 0.39 cm. The length of the thoracic region was in the range from 32.23 cm to 37.74 cm, on average 34.8 ± 0.32 cm. The length of the
lumbar spine varies from 11.75 cm to 13.76 cm, on average of 12, 07 ± 0.56 cm. The length of the sacrococcygeal region varied from 11.31 cm to 13.24 cm, on average of 12.22 ± ± 0.65 cm.
Thus, Increasing in the length of the spinal column in female children between 13 and 16 years in the cervical and sa-crococcygeal region occurs more intensively in compare with the thoracic and lumbar part of spinal colum and increasing in the length of the spinal column in male between 13 to 16 years in the cervical and sacrococcygeal region occurs more intensively than in the thoracic and lumbar region.
Conclusions:
1. The total length of the spinal column in girls from 13 to 16 years increases 1.16 times and in boys 1.24 times;
2. The growth rates for girls aged 13 to 16 years increased 1.16 times, boys 1.24 times. The size of the cervical part in girls aged 13 to 16 years increases by 1.20 times and in boys 1.29 times; the length of the thoracic part in girls between 13and 16 years increases 1.14 times, in boys 1.21 times, the length of the lumbar region in girls increases 1.14 times in boys 1.16 times and the length of the sacrococcygeal part in girls is increased by 1.21 times, in boys 1.29 times.
3. The growth rate of spinal column is more intensive in boys aged 13 to 16 in compare of same aged girls
