Growth of preterm newborns during the first 12 weeks of life

Summary The aim of the study was to develop the norms for physical growth (birth weight-, birth height- and head circumference- for age) of the full-term babies born from singleton pregnancy in UMHAT „Dr. G. Stranski” – Pleven (total, by gender and gestational age at birth). A cross-sectional study was carried-out in 2017; 1092 live infants born from singleton pregnancy between 38 and 42 weeks were included in the study. We obtained information about three anthropometric measurements (birth weight-, birth height- and head circumference-for age). Data were processed by SPSS v.24.0. Norm group ranges (3, 5 and 7 groups) were developed for three indicators using percentile methods. Kruskal-Wallis test was used. The mean birth weight- and height-for age were higher for baby boys (P50, 3280 g and 50 cm) compared with baby girls (P50, 3150 g and 49 cm). Baby boys and girls weighed <2570 g at birth fell into the group ,,very slow growth” (P3). A ,,very fast growth” (P97) was found in baby boys weighed >4120 g at birth (vs. >3870 g for baby girls). Norm group ranges allow to identify the newborns with a higher risk and to focus efforts and health resources to them; it should be updated periodically.

“…With regard to weight for gestational age, a different pattern was found in which NBs classified as SGA at birth had a greater likelihood of having adequate weight in the third phase of the KM. According to Anchieta et al (2004a), SGA NBs tend to lose less weight and recover more rapidly than AGA NBs, and also have larger head circumference measurements.…”

“…Preterm NBs are at higher risk of fetal growth restriction and post-natal growth deficits, which may be associated with subsequent adverse outcomes in neurodevelopment (Tudehope et al 2012). However, despite the importance of awareness of the growth process, its monitoring is often neglected during the hospital stay, a period which may be lengthy in preterm NB (Sassá et al 2011;Anchieta et al 2004a).…”

Objectives The Kangaroo method helps promote maternal breastfeeding and adequate growth of low birthweight preterm infants. The objective of this study was to analyze the association between weight-gain velocity during use of the Kangaroo method and maternal and infant variables. Methods A nested cross-sectional study in a cohort of newborn infants managed using the Kangaroo method was carried out at a reference center for the method in Brazil. Data on low birthweight and preterm infants managed using the Kangaroo Method (n = 78) and on their respective mothers (n = 70) was collected between January and July 2014. Maternal and infant variables were associated and correlated with weight-gain velocity (g/kg/day) at each phase of the method (p < 0.05). Results Mean weight-gain velocity increased from 0.12 ± 11.11 g/kg/day in the first phase to 13.47 ± 4.84 g/kg/day in the third phase (p < 0.001), and percentage of adequate weight increased at phase 3 (p < 0.001). Birthweight was inversely correlated with weight-gain velocity at phases 1 and 2 of the Kangaroo method. Birthweight of under 1500 g was associated with a lower likelihood of inadequate weight-gain velocity of the newborn at phase 1 (OR = 0.1; 95 % CI 0.01-0.78; p = 0.012). In phase 3, maternal age was directly correlated with weight-gain velocity. Conclusions Weight-gain velocity was associated with maternal (age) and infant (gestational age at birth, birthweight, weight for gestational age at birth, length of hospital stay and five-minute Apgar score) variables. Knowledge of the factors influencing weight-gain velocity and its behavior at each phase of the method can help guide conduct toward potentializing factors that promote adequate weight-gain.

“…Parallel to the gain in body mass is the gain in brain mass due to the continued development of the nervous system after birth. Thus, the head circumference is used clinically to evaluate the growth of the neonate and also diagnose changes such as macro and microcephaly (LEONE et.al 2017, ANCHIETA, 2004, Xavier, 1995. This normal growth is accompanied by a graph called the "Growth Curve", in which the expected increase in the variables mentioned through the weeks after birth is presented.…”

Throughout human history, the morphological aspects of the child have been viewed in different ways by different cultures, and many researchers did not believe in their uniqueness and saw them as "mini adults". As a consequence, there was a neglect of the morphological peculiarities of the child. All this contributed to the fact that the number of studies on morphofunctional growth and development was scarce, so that professionals such as physiotherapists, speech therapists, pediatricians, nurses, among other professionals had insufficient material for consultation. In this sense, an analysis of the factors responsible for the growth and development of the newborn and the child was developed. For this, a systematic review was developed from the survey of morphological and functional data of the newborn and the child.

Growth of preterm newborns during the first 12 weeks of life

Abstract: The dynamics of the preterm infants evaluated was similar to that of previous studies. The infants also presented growth deficit. However, it was also noted that the infants present a high potential to recover their growth.
