    Abstract:
    The purpose of this study was to investigate changes in anthropometrical characteristics during the last year (autumn-spring) in preschool and first year (autumn-spring) in school. Changes in anthropometrical characteristics during summer months were also studied (spring-autumn). The subjects were 130 boys and 122 girls, 6 years of age at the beginning of the investigation. The body height and mass were measured and the BMI (kg/m2) was calculated. In total, eight skinfolds, 10 girths and two bone widths were measured. In boys, the body height and mass were higher than in girls, while the skinfold thicknesses were thicker in girls. There were only very few significant differences between sexes in girth parameters. The width parameters were higher in boys. Our results indicated that there were more significant changes in skinfold thickness, girths and width parameters during winter in preschool in comparison with first year in school in boys, while there were only a very few significant changes during summer months in boys. In contrast, there were more significant changes in school in girls. The Spearman correlations between baseline and after 6, 12 and 18 months of study indicated that the tracking of body height was high in boys and girls. Body mass tracking was high in girls and moderate in boys, while BMI tracking was moderate in both groups. The tracking coefficients of skinfold thicknesses were relatively stable during the two years of study and mostly at the moderate level (r = 0.3-0.6). Tracking coefficients of girths measures were at moderate level, but lower in boys in comparison with girls. It was concluded that social changes and probably changes in the physical activity during transition from preschool to school slightly influenced the measured anthropometrical parameters.
