“…However, there are numerous publications in the literature that assess the physical development of children of different ages according to gender (Szabo et al, 2013), genetic inheritance (Delemarre van Waal, 1993) and various environmental factors (Cojocaru et al, 2015;Delemarre van Waal, 1993;Pietiläinen et al, 2002;Stănescu et al, 2018;Szabo et al, 2013).
