means of our file and file B1961 were ratedin children aged from 2 months to 1.74 y.(expressed in Z-scores the means variedfrom 0.7 to 1.6 S.D.). Though we couldcompare three age categories, statisticallysignificant differences of means of our fileand file K1983 were rated in girls at birth(0–4 d.) and in children aged 1 and 3 years.Antero-posterior chestdiameter (cm)Table 5Curves of the mean values increasedrapidly at the beginning of the researchperiod until 1 year of age in girls (agecategory 1.00–1.25 y.) and 1.5 year in boys(1.50–1.74 y.). Then, absolute incrementsintensively decreased (fluctuations of themeans are caused by numbers of probandsin age categories). After 2 years of agea moderate increase of means follows.Mean values of parameter at birth are8.2 cm (boys) and 8.1 cm (girls), at the endof the research period (age category 3.00–3.49 y.) 12.2 cm (boys) and 11.9 cm (girls).The dynamics of growth in antero-posteriorchest diameter in boys and girls isanalogous. Mean values of the diameterin girls are slightly lower than in boys innearly every age category. Differences ofthe mean values of 2–3.49-year-olds varybetween 0.3 cm and 0.4 cm.B1961 (Bouchalová, 1987) K1983 (Krásničanová, 1989)Age N Mean S.D.
