values for our file in the whole researchperiod (expressed in Z-scores the meansvaried from 0.3 to 0.5 S.D.). Unfortunatelycomparative data of chest circumference offile B1961 are not available.Transverse chest diameter (cm)Table 4The mean values steeply increase at thebeginning of the research period throughage category 2.00–3.99 m. Then absoluteincrements of the mean values decreasemarkedly and after 8 months of age (8.00–9.99 m.) the increments decrease fluentlyto the end of the research period.Mean values of parameter at birth are9.4 cm (boys) and 9.1 cm (girls), at the endof the research period (age category 3.00–3.49 y.) 16.9 cm (boys) and 16.5 cm (girls).Curves of the mean values in boys andgirls have almost identical development.Mean values of the diameter in girls areslightly lower than in boys in almost all agecategories; differences of the mean valuesof boys and girls slowly increase and from8 months of age to 3.49 years vary between0.4 cm and 0.5 cm.Comparison of transverse chestdiameter of our file and files B1961 andK1983 showed lower mean values in ourfile in almost the whole research period.Statistically significant differences ofAge 2001–04Days d., months m.
