“…A systematic review of growth patterns and body composition among ELBW neonates stated that, despite catch-up growth, their weight, height, and HC growths remained retarded into adulthood. (29,36,37) Pre-or full-term born SGA children were shorter and lighter until 3 years of age than AGA children (34,(38)(39)(40)(41). The growth velocity of SGA children was significantly higher than that of AGA children in the first 2 years of life (39).…”

The growth velocity of SGA children was significantly higher than that of AGA children in the first 2 years of life (39). In a single-center study in Korea, 29% of SGA, 33% of severe SGA (<3 rd percentile), and 36.4% of moderate SGA (3 rd -10 th percentile) infants did not reach catch-up growth for weight goals at 24 months of PCA (15,42).…”

Growth patterns of preterm infants in Korea

With advancements in neonatal care and nutrition, the postnatal growth of preterm infants has improved; however, it remains an issue. Accurate assessments of growth using a standardized reference is needed to interpret the intrauterine and postnatal growth patterns of preterm infants. Growth in the earlier periods of life can contribute to later outcomes, and the refinement of postnatal growth failure is needed to optimize outcomes. Catch-up growth occurs mainly before discharge and until 24 months of age, and very low birth weight infants in Korea achieve retarded growth later in life. Knowing an infant's perinatal history, reducing morbidity rates during admission, and performing regular monitoring after discharge are required. Preterm infants with a lower birth weight or who were small for gestational age are at increased risk of poor neurodevelopmental outcomes. Furthermore, poor postnatal growth is predictive of adverse neurodevelopmental outcomes. Careful monitoring and early intervention will contribute to better development outcomes and national public health improvements.

“…The mean WAZ of preterm infants during corrected 24 months of age was > -1.3, and the percentage of zscores was < -1.3, decreasing from 13.78% at CA 0 months to 6.81% at CA 24 months. Other studies [14][15][16] have also demonstrated that the majority of premature babies catch up on growth within the rst two years of life and usually reach it within the rst two years. In our study, weight catch-up was more signi cant than length, particularly between CA 0 and 3 months.…”

Purpose This study aimed to analyze the growth of preterm infants after birth regarding weight, length, and head circumference (HC) and determine the risk factors affecting their catch-up growth. Methods Anthropometric data and clinical information from 288 preterm infants were collected. Z-scores were calculated using the World Health Organization Anthro software. Logistic regression analysis assessed the risk factors for catch-up growth in preterm births. Results The percentage of preterm infants with z-scores <-1.3 for weight, length, and HC decreased from 13.78%, 11.31%, and 7.42–6.81%, 4.26%, and 4.68%, respectively, between 0 and 24 months of corrected age (CA). The weight z-score increased between CA 0 and 3 months in non-small for gestational age (SGA); the increased weight z-score in SGA extended to CA 9 months. Non-SGA had elevated length z-scores from CA 0 to 6 months, and SGA length z-scores were elevated for an extended period until CA 9 months. Z-score differences in weight and length of SGA and non-SGA preterm infants decreased with increasing CA. Gestational age (OR = 2.814, 95%CI: 1.32–5.997) and birth weight (OR = 0.998, 95%CI: 0.997–0.999) were risk factors for catch-up growth at CA 24 months. Conclusion Most catch-up growth occurs in the first year of life. Compared to the non-SGA group, preterm infants in the SGA group showed more pronounced and prolonged catch-up growth, particularly in weight and length. We concluded that gestational age and birth weight were risk factors for catch-up growth.

“…Children who fail to achieve catch up growth within 2 years of life remain short after childhood so an early initiation of growth hormone treatment was recommended by previous research [29,30]. The length Z and changes of scores at 12 months of corrected age may be correlated with catch-up height at 3 years and so it is useful for earlier initiation of growth hormone treatment in VLBW infants [31].…”

This study aimed to investigate the nationwide growth pattern of infants in Korea according to the birth-weight group and to analyze the effect of growth on development. A total of 430,541 infants, born in 2013 and who received the infant health check-up regularly from 6 months to 60 months of age, were included. The weight, height, head circumferences percentiles, and neurodevelopment using screening tests results were compared among the birth-weight groups. Using longitudinal analysis, the study found a significant difference in height, weight, and head circumference, respectively, according to age at health check-up, birth weight group, and combination of age and birth weight (p < 0.001). The growth parameters at 60 months of age showed a significant correlation with those at 6 months of age especially in extremely low birth weight infants. The incidence of suspected developmental delay was significantly higher in infants with growth below the 10th percentiles than in those with growth above the 10th percentiles. Among 4571 (1.6%) infants with suspected developmental delay results at 60 months of age, birth weight, sex, and poor growth parameters were confirmed as associated factors. This nationwide Korean study shows that poor growth and neurodevelopment outcomes persisted among low-birth-weight infants at 60 months of age. Our findings provide guidance for developing a nationwide follow-up program for infants with perinatal risk factors in Korea.
