Postural disorders and disorders of nutritional status in children are quite frequent and also carry various risks of possible health problems. The aim of this research was to analyse postural disorders in younger school-age children, 7 - 10 years old, as well as their incidence with regard to category of nutritional status and gender dimorphism. The sample of subjects comprised of 335 younger school-age children, 7 - 10 years old, of both genders (174 girls and 161 boys), pupils of the primary school “Sveti Sava”, Bačka Palanka. Postural status was assessed by Napolen Volansky method. Data processing involved statistical package SPSS for Windows, version 15. In establishment of differences in postural status, with regard to the age and the gender dimorphism, we used χ2 test. In order to establish differences in cumulative evaluation of postural status, we applied rank-sum Mann-Whitney Z-test, which is equivalent to T-test for categorical data. In establishment of differences in groups of subjects formed on the basis of degree of nutritional status, we applied Kruskal-Wollis test. According to the obtained results, total evaluation of postures of children of both genders established no statistically significant differences, yet that higher rank was established in girls, which indicates to poorer bad posture in female subjects (7-8 years of age: Z=-0.133; р=0.894; 9-10 years of age: Z=-0.993; р=0.321). Through analysis of distribution of nutritional status categories, formed on the basis of the BMI determined according to the gender, it was established that the difference is at the limit of statistical significance in children of 7-8 years of age (χ2 = 7.401; р = 0.06). In children of 9-10 years of age, no statistically significant difference was established. Statistically significant difference in incidence of postural disorders with regard to category of nutritional status was noticed in the subsample of children of 9-10 years of age (χ2 = 53.802; p = 0.000). These results lead to conclusion that younger school-age children should get involved in organized and continuous physical activities in order to prevent occurrence of postural disorders and obesity.
