Objective: to study the rates of increase in body weight (BW), body length (BL) and head circumference (HC) in infants with VLBW; define significant factors affecting the rates of postnatal growth (PG) for each parameter; identify correlations between the factors and PG parameters. 

Patients and methods. The assessment of PG of infants with VLBW (n=92) and ELBW (n=34) was carried out during three time intervals: in the neonatal intensive-care unit (NICU), in the special care nursery and from birth until the hospital discharge. 

Results. Average PG rates in infants with VLBW and ELBW (the growth of BW, BL and HC) in NICU amounted to 8.63 g/day, 0.89 cm/week and 0.4 cm/week respectively; in the special care nursery: 24.2 g/day, 0.94 cm/week, 0.7 cm/week respectively; during the entire treatment period: 18.23 g/day, 0.92 cm/week and 0.6 cm/week respectively. The growth of BW and HC in infants with VLBW and ELBW during the entire treatment period was directly proportional to the growth of BW, BL and HC in NICU; the growth of BW, BL and HC in the special care nursery, as well as the BL growth during the entire treatment period. The growth of PG parameters was inversely proportional to the BW, BL and HC at birth. 

Conclusion. The PG rates are directly proportional to the growth of all PG parameters and inversely proportional to the PG parameters at birth. 

Key words: very low birth weight (VLBW), extremely low birth weight (ELBW), postnatal growth, body weight, body length, head circumference.
