(7), expressed by Z-scores the mean valuesdiffer in 0.2–0.3 S.D.Comparison of boys (3.00 m.–3.49 y.)from our file and comparative files (B1961and K1983) and girls (3.00 m.–3.49 y.)from our file and file B1961 showed highermean values in our file. Although the differencesof mean values of recumbentlength and standing height of our file andcomparative files (B1961 boys and girlsand K1983 boys) are predominantly insignificantin 0–11.99-month-old children, thedifferen ces of the means in children aged1.00–3.49 years are statistically significant(expressed in Z-scores the means variedfrom 0.3 to 1.2 S.D.).Body weight (kg)Table 2Development of tissues and organs ofa child’s body reflects the developmentof body weight. Consequently the bodyweight is used for overall assessment ofthe child’s growth as well as for an explanationof other body characteristics development.The mean values steeply increase at thebeginning of the research period throughthe age category 1.00–1.99 m. Thenabsolute increments of the mean valuesdecrease and after 1 year of age the incrementsdecrease fluently to the end of theresearch period.Age 2001–04Days d., months m.
