The physical development of children of school age (7—17 years) in the Kirghiz Republic

The article presents the results of comparative analysis of indices of physical development of school-age children residing in various regions of the Republic of Kyrgyzstan. The statistically significant relationship between body length and body mass of examined children from territories of their residence was established. The children from Bishkek had significantly higher values as compared to children from villages of highlands and the south and the north of the country as well. The statistically significant dependence of body length and body mass of examined children on gender was revealed, explained by higher anthropometric indices in boys, as compared with girls in age categories of 7-8 years and 15-17 years. The multivariate variance analysis established that territorial factor statistically significant affected anthropometric indices in all studied age categories. At that, input of this factor into indices dispersion did not exceed 10%. The input of sex assignment to variance of body height and body mass in children under age of 14 years was insignificant. However, in the age of 15 years and older effect of this factor on anthropometric indices increased significantly, reaching its maximum by the age of 17 years and significantly predominating over influence of territorial factor.
