Regional differences in somatic development of pre-school children in context of secular changes
Ferris, Stáňa ; Sedlak, Petr (advisor) ; Zamrazilová, Hana (referee)
Testing of regional differences in the growth and development of preschool children is a neglected topic in the history of anthropometry. In this work, we focused on the differences between the current population of Prague, Olomouc and Bratislava. Given the very similar living conditions and socioeconomic maturity of all three regions, we did not anticipate their presence. However, the results of this work showed significant differences, especially in skeletal robustness. Furthermore, we tested the presence of secular differences in the growth and development of preschool children between the current population of Prague, Olomouc and Bratislava and the reference data from 1990 for Czechia and 1989 for Slovakia. We expected changes in height, length and width body parameters, gracility of skeletal robustness, and, on the contrary, an increase in adiposity markers. In the case of the Prague population, this hypothesis was confirmed except for changes in the width parameters of the pelvis, where a negative secular trend was demonstrated. The results of the Olomouc and Bratislava populations do not agree with European trends and the established hypothesis. Secular trends in growth and development are mostly positive. Key words Regional differences, secular trend, preschool age, growth and developement
