“…Zhao et al [23] showed that SGA was associated with lower weight and length. The incidence of growth failure in our report was lower than that reported in developing countries [17, 19, 20]. VLBW and SGA preterm infants benefit from improvements in nutritional support and routine follow-up.…”

“…Correspondingly, the incidences of stunting and microcephaly were higher in the VLBW and SGA preterm infant groups. Previous studies have shown that the growth failure rate among VLBW infants is as high as 50% at 12 months of CA [17, 19, 20]. For SGA preterm infants, Knops et al [21] found that very preterm AGA infants showed no stunting at 10 years of age; however, many SGA children showed persistent stunting.…”

“…Nagasaka et al [22] found that the incidence of short stature was 2-fold higher among preterm infants than among term infants at 3 years of age, but the incidence of short stature was 4.5-fold higher among SGA preterm infants than among term infants. Another study observed that growth failure rates were higher for SGA infants than for AGA infants [20]. Zhao et al [23] showed that SGA was associated with lower weight and length.…”

BackgroundThe aim of this study was to follow the growth and hematological indicators of preterm infants during their first year.MethodsNeonates below 37 gestational weeks had routine follow-ups up through 1 year from January 2012 to December 2015 at West China 2nd University Hospital, Sichuan University. Weight, length and head circumference (HC) were measured monthly during the first 6 months, followed by monitoring every second month until 12 months. The catch-up growth defined as a gain of Z-score > 0.67 according to previous study. All preterm infants were prescribed iron prophylaxis based on national guideline. The hemoglobin concentration was examined at 6 and 12 months.ResultsAltogether, 132 very-low-birth-weight (VLBW), 504 low-birth-weight (LBW) and 198 normal-birth-weight (NBW) infants were followed. The rates of catch-up growth for weight, length and HC 12 months of corrected age (CA) were 22.6, 29.1 and 14.6%, respectively. SGA and VLBW infants showed higher catch-up growth rates. The overall prevalence of anemia was 6.8% at 6 months and 7.8% at 12 months. The Z-scores for weight-for-length, length and HC were lower in the VLBW and SGA preterm infant groups than in the other preterm groups throughout the first year of life. The incidences of stunting, microcephaly and wasting changed from 5, 1.3 and 3.7% to 2, 1.1, 0.9 and 2.4%, respectively, during the first year. However, the incidences of wasting and stunting were higher for the VLBW infants than for the LBW and NBW infants at 12 months (9.3% vs. 1.4%, p < 0.01; 9.3% vs. 1%, p < 0.01,respectively; 4.7% vs. 0.8%, p < 0.01, 4.7% vs. 0%, p < 0.01,respectively). Similar results were observed between SGA and AGA infants (8.7% vs. 1.5%, p < 0.01; 5.8% vs. 0.4%, p < 0.01). Logistic regression revealed SGA and VLBW as risk factors for poor growth (WLZ < -2SD) at 12 months (OR = 5.5, 95% CI: 2.1–14.8, p < 0.01: OR = 4.8, 95% CI: 1.8–12.8, p < 0.01, respectively).ConclusionThe VLBW and SGA preterm infants showed significant catch-up growth during their first year of life. However, SGA and VLBW were risk factors for poor growth during the preterm infants’ first year of life. Prophylactic iron supplementation in preterm infants appears to reduce the prevalence of anemia.

“…Likewise, growth failure has been defined as weight and height below the 10th percentile at 24 months using fetal growth charts in another study. 17) We defined catch-up growth as growth parameter over 10th percentile of normal Korean infant's growth curve. Approximately 10%–25% of children born SGA fail to show catch-up growth and remain short as adults.…”

PurposeSmall for gestational age (SGA) is confusingly defined as birth weight (BW) either below 3rd percentile or 10th percentile for infants. This study aimed to compare postnatal catch-up growth between SGA groups according to different definitions.MethodsData of 129 infants born with BW below the 10th percentile and admitted to Korea University Anam Hospital and Ansan Hospital were retrospectively reviewed. Height and weight were measured at 6, 12, and 24 months. Results were compared between group A (BW: <3rd percentile) and group B (BW: 3rd–10th percentile).ResultsGroup A included 66 infants and group B included 63. At age 6 months (n=122), 62.9% of group A and 71.7% (P=0.303) of group B showed catch-up growth in weight. At 6 months (n=69), 55.9% of group A and 80.0% of group B (P<0.05) showed catch-up growth in height. At 12 months (n=106), 58.5% of group A, and 75.5% (P=0.062) of group B showed catch-up growth in weight. At 12 months (n=75), 52.8% of group A and 64.1% of group B (P=0.320) showed catch-up growth in height. Up to age 24 months, 66.7%/80.0% in group A and 63.6%/80.0% in group B showed catch-up growth in weight/height.ConclusionDespite different definitions, there were no significant differences between the two SGA groups in postnatal catch-up growth up to age 24 months, except for height at 6 months. Compared to infants with appropriate catch-up growth, low gestational age and BW were risk factors for failed catch-up growth at 6 months.

“…In 2016, Gri n et al [7] analyzed the data of the California Perinatal Quality Care Collaborative from 2005 to 2012 and found that the incidence of EUGR at discharge of very low birth weight infants (VLBWIs) was 52.7% and 44.4% in the 1000-1249 g and 1250-1500 g groups, respectively. In 2017, Park et al [8] reported that at 40 weeks of corrected gestational age, the incidence of EUGR was 58.4% by the weight and 50.5% by the height. In China, the incidence of EUGR was higher.…”

Objective: To study the association between the growth and development of extremely preterm infants at the neonatal intensive care unit (NICU) and their intestinal microfloraMethods: Extremely low gestational age infants admitted to the NICU were included in this study. The subjects were divided into the extrauterine growth retardation (EUGR) group and normal growth group, and the growth and development were evaluated at 2 and 4 weeks after birth. Meanwhile, the stool samples were taken to perform high throughput 16S rRNA sequencing of the intestinal microflora.Results: A total of 22 infants were included. There was no significant difference in the alpha diversity indexes the two groups at 2 weeks or 4 weeks after birth. The beta diversity analysis showed that the principal components of the intestinal microflora were similar between the two groups. LEfSe analysis showed that after 2 weeks of birth, the items with an absolute LDA higher than 4 included Streptococcaceae, Streptococcus, Bacteroidetes, Bacteroidales and Stenotrophomonas in the EUGR group and Enterococcaceae and Enterococcus in the control group. At the 4th week after birth, the items with an absolute LDA higher than 3 in the EUGR group included Clostriaceae, Eubacteriaceae and Eubacterium. The microbial community composition comparison showed significant differences in the principle components of Enterococcus and Streptococcus on the family and genus levels.Conclusion: The diversity and richness of the intestinal microflora in preterm infants at the NICU are significantly insufficient, and the establishment of intestinal homeostasis is obviously delayed, which may cause growth retardation.
