Успешность обучения школьников 1-11 классов в зависимости от массы тела при рождении и пола
Success of training of students of 1-11 classes depending on weight of the body at the birth and the gender

Summary/Abstract: In the modern literature strongly represented results of research of survival rate and health of children born with weight of a body less 1 000 г, as well as physical and mental progress of such children till 3–4 years. The question on the remote consequences for the person born with low weight of a body, remains opened though a number of authors notes lower level of development of intelligence at first-graders and 14-years teenagers born with extremely low and low weight of a body. The objective of our research consisted in the retrospective analysis of success of training (with 1 on 11 classes) of graduates of comprehensive schools of Kirov de-pending on their weight of a body at a birth and a gender. Success of training estimated on the basis of annual marks on separate disciplines in each class and on a mean score reflecting to-tally progress on the basic disciplines of each class. All subjects (n = 251) have been divided in-to groups: group M – born with a weight less 2500 g (9 girls and 5 boys), group N – the bodies which have born with normal weight (110 girls and 95 boys) and group В– the bodies which have born with the big weight, hose more than 3 900 g (13 girls and 19 boys). It was found that the success of training of schoolboys of 1–11 classes who had birth weight of 1.6 kg to 3.5 kg inclusive, the higher, the higher the birth weight, which is especially true for boys. Thus, the rate of postnatal brain maturation in children depends on the body weight at birth. This points to the need to develop special methods of teaching children born with low birth weight. From a physiological point of view, the results of the study point to the prospect of studying the effect of birth weight and sex of the child in the on mechanisms of maturing of neocortex at postnatal stages of human development.
