Výskyt vadného držení těla, nadváhy a obezity u dětí mladšího školního věku: pilotní studie

Abstract

The aim of our work was to chart and analyse the occurrence of primary school children defective body posture and its connection with obesity. The research sample was made of 204 primary school children (109 girls and 95 boys) of average age 8,1 ± 0,33 years (girls 8,3 ± 0,38, boys 7,9 ± 0,32). The probands average height was 134 ± 10,7 cm (girls 134,5 ± 11,6 cm, boys 134,1 ± 9,6 cm). The probands average weight was 31,1 ± 9,2 kg (girls 31,2 ± 9,8 kg, boys 31,1 ± 8,7 kg). The body height was measured with anthropometer, the body weight was weigh with Tanita BC571. The probands monitoring of body posture was charted by a diagnostic system DTP-3. A device analyses a body posture by a non-invasive method. We have investigated that 10 girls are obese, 9 girls have excessive weight, 15 girls are robust, 47 are proportional, 24 slim and 4 girls are thin. From research group are 9 boys obese, 9 boys have excessive weight, 11 boys are robust, 49 boys are proportional, 14 boys are slim and 3 boys are thin. From the results it is evident that in the area of a neck lordosis none of the probands is in a norm. From all the sample, 13 probands have a moderate deviation (6,4 %), 24 a substantial deviation (11,8 %) and 167 probands have a very substantial deviation (81,9 %). In the area of a loins lordosis there are 24 probands in a norm (11,8 %), 75 have a moderate deviation (36,8 %), 19 probands have a substantial deviation (9,3 %) and 86 probands have a very substantial deviation (42,2 %). In the area of a pectoral kyphosis there are 27 probands in a norm (13,2 %), 56 probands have a moderate deviation (27,5 %), 58 probands have a substantial deviation (28,4 %) and 63 probands have a very substantial deviation from the norm (30,9 %). From all the results it is obvio us that 18 % of girls and 19 % of boys are in the group of fat or obese children and that in the sample of primary school children there are very clear deviations from a good body posture. This fact was found out without any reference to their weight. A significant relation between the norm of body posture and BMI was found just in the area of neck lordosis (p ≤ 0,002).
