Abstract Background and Purpose. Study of kicking development provides important information to understand how early spontaneous movements change in infants as they acquire voluntary control. Researchers have investigated the kicking movements of preterm infants; however, the movement patterns that they have described were inconsistent. The purpose of this study, therefore, was to examine the development of kicking movements with kinematic analysis in preterm infants with very low birth weight (VLBW) and full-term infants. Subjects and Methods. Twenty-two infants with VLBW who were divided into low gestational age (gestational age of <30 weeks, n=9) and high gestational age (gestational age of ≥30 weeks, n=13) classes and 22 full-term infants were evaluated during kicking movements using 4 synchronized cameras and 3-dimensional kinematic analysis when the infants were 2 and 4 months of corrected age. Results. The infants with VLBW and a high gestational age showed similar kicking movements compared with the full-term infants. In contrast, the infants with VLBW and a low gestational age exhibited a higher kick frequency and a shorter flexion phase at 4 months of corrected age. They also exhibited a higher hip-knee correlation and lower variability in the interlimb coordination pattern at 2 and 4 months of corrected age. Discussion and Conclusion. The findings indicate that infants with VLBW, particularly those with a low gestational age, have age-related differences in movement organization and coordination of kicking compared with full-term infants.

ABSTRACT Objective: To compare somatic growth, lung function, and level of physical activity in schoolchildren who had been very-low-birth-weight preterm infants (VLBWPIs) or normal-birth-weight full-term infants. Methods: We recruited two groups of schoolchildren between 8 and 11 years of age residing in the study catchment area: those who had been VLBWPIs (birth weight < 1,500 g); and those who had been normal-birth-weight full-term infants (controls, birth weight ≥ 2,500 g). Anthropometric and spirometric data were collected from the schoolchildren, who also completed a questionnaire regarding their physical activity. In addition, data regarding the perinatal and neonatal period were collected from the medical records of the VLBWPIs. Results: Of the 93 schoolchildren screened, 48 and 45 were in the VLBWPI and control groups, respectively. No significant differences were found between the groups regarding anthropometric characteristics, nutritional status, or pulmonary function. No associations were found between perinatal/neonatal variables and lung function parameters in the VLBWPI group. Although the difference was not significant, the level of physical activity was slightly higher in the VLBWPI group than in the control group. Conclusions: Among the schoolchildren evaluated here, neither growth nor lung function appear to have been affected by prematurity birth weight, or level of physical activity.

Abstract Background and Purposes. Although early kicking differences have been reported for preterm infants without overt cranial sonographic abnormalities, their functional importance remains unclear because no outcomes have been measured. Therefore, the first purpose of this prospective study was to examine the age of walking attainment in preterm infants who had very low birth weight (VLBW) but no overt neurosonographic abnormalities and full-term infants without known impairments or pathology. The second purpose was to examine the relationship between spontaneous kicking and age of walking attainment in these infants. Subjects and Methods. Twenty-two preterm infants and 22 full-term infants were examined for kicking movements at 2 and 4 months corrected age and were followed up for age of walking attainment until 18 months corrected age. Results. Survival analysis showed that infants with VLBW attained walking ability at older ages than full-term infants after correction for prematurity. Cox proportional-hazards regression analyses for all infants revealed that a high hip-knee correlation at 2 months corrected age, a high kick frequency at 4 months corrected age, and a short intra-kick pause together with a low variability in interlimb coordination at 2 and 4 months corrected age were all associated with a decreased rate of walking attainment. Discussion and Conclusion. The results indicated that preterm infants who had VLBW but no overt neurosonographic abnormalities had an increased risk of delayed walking attainment compared with full-term infants. Alterations of spontaneous kicking may predict a decreased rate of walking attainment in both preterm and full-term infants.

Objective The objective of this study was to investigate the neurodevelopment and growth of very low birth weight (BW) preterm infants, at 8 and 18 months corrected age (CA), compared with full term in Brazil. Methods Prospective cohort study including 83 preterm infants with BW ≤ 1,500 g and gestational age ≤ 32 weeks, and 52 full-term control infants. Preterm infants free from significant sensory and motor disability, and from congenital anomalies were included. Alberta infant motor scale (AIMS) and Brunet–Lèzini scale (BLS) were used to evaluate the neurodevelopment at 8 and 18 months. Anthropometric measurements were collected to evaluate the growth in both age groups. Results At 8 months CA, preterm infants scored significantly lower in total AIMS score (p = 0.001). At 18 months, they scored significantly lower on the stand subscale from AIMS (p = 0.040) and exhibited poor psychomotor development in the BLS (p = 0.006). The nutritional status showed significant differences between the groups, in both age groups (p < 0.001). There were positive correlations between nutritional status and AIMS (r = 0.420; p < 0.001) and BLS (r = 0.456; p < 0.001) at 8 months, and between head circumference and BLS (r = 0.235; p < 0.05) at 8 months and AIMS (r = 0.258; p < 0.05) at 18 months. Conclusion Very low BW preterm infants at 8 and 18 months CA showed significant differences in the neurodevelopment and growth pattern when compared with their full-term peers.

OBJECTIVE: The aim of the present study was to compare the beginning of eruption of the first deciduous tooth in preterm infants (<38 weeks) with full-term infants (38 and 42 weeks) of normal birth weight (³2.500g), low birth weight (< 2.500g) and very low birth weight (<1.500g), in order to evaluate if premature birth and low birth weight would affect tooth eruption. METHODS: The neonatal records and the moment of eruption of the first deciduous tooth of 146 infants - 77 preterm infants and 69 full-term infants, ranging from 5 to 36 months old, of both genders - were recorded. All of them were under care at the Pediatric Ambulatory of Hospital Universitário Evangélico at Curitiba - Parana. Data were analyzed considering biological age and post-conception, or corrected, age - which is the gestational age plus the infant's chronological age at the month of eruption of the first deciduous tooth. RESULTS: Results showed that when chronological age is considered, tooth eruption in preterm and very low birth weight infants is importantly delayed. However, when corrected age is considered, no statistically significant differences were found among groups. CONCLUSION: The delayed eruption may be related to the premature birth and not to a delay in dental development.

Abstract Background Antenatal corticosteroids (ACS) treatment is critical to support survival and lung maturation in preterm infants, however, its effect on feeding and growth is unclear. Prior preterm delivery, it remains uncertain whether ACS treatment should be continued if possible (repeated course ACS), until a certain gestational age is reached. We hypothesized that the association of single-course ACS with feeding competence and postnatal growth outcomes might be different from that of repeated course ACS in very-low-birth-weight preterm infants. Methods A multicenter retrospective cohort study was conducted in very-low-birth-weight preterm infants born at 23–37 weeks’ gestation in South China from 2011 to 2014. Data on growth, nutritional and clinical outcomes were collected. Repeated course ACS was defined in this study as two or more courses ACS (more than single-course). Infants were stratified by gestational age (GA), including GA < 28 weeks, 28 weeks ≤ GA < 32 weeks and 32 weeks ≤ GA < 37 weeks. Multiple linear regression and multilevel model were applied to analyze the association of ACS with feeding and growth outcomes. Results A total of 841 infants were recruited. The results, just in very-low-birth-weight preterm infants born at 28–32 weeks’ gestation, showed both single and repeated course of ACS regimens had shorter intubated ventilation time compared to non-ACS regimen. Single-course ACS promoted the earlier application of amino acid and enteral nutrition, and higher rate of weight increase (15.71; 95%CI 5.54–25.88) than non-ACS after adjusting for potential confounding factors. No associations of repeated course ACS with feeding, mean weight and weight increase rate were observed. Conclusions Single-course ACS was positively related to feeding and growth outcomes in very-low-birth-weight preterm infants born at 28–32 weeks’ gestation. However, the similar phenomenon was not observed in the repeated course of ACS regimen.

<p>OBJECTIVE: In the present study, we investigate the growth characteristics of very low birth weight premature infants of up to two years corrected age, considering the factors affecting growth and catch-up growth time.</p><p>STUDY DESIGN: The demographic data, clinical features, and comorbidities of 77 preterm infants with birth weights of less than or equal to 1.500 g were examined, the infants’ growth statuses in the 40th gestational week (gw) and at 6, 12, 18 and 24 months the corrected age, including their weight, height and head circumference, were evaluated.</p><p>RESULTS: The findings revealed that very low birth weight infants should be closely monitored either during their stay in the Neonatal Intensive Care Unit, or for up to 6 months corrected age, paying particular attention to growth data, and the appropriate supportive treatment should be administered. The applied support process is influential on the future somatic growth of preterm infants. It was noted in the study that bronchopulmonary dysplasia, proven sepsis, respiratory distress syndrome, steroid treatment for more than three days, patent ductus arteriosus, and ibuprofen treatment seemed to affect somatic growth negatively.</p><p>CONCLUSION: Small for gestational age newborns were found to catch up with appropriate for gestational age newborns at 2 years corrected age in terms of growth, although the percentage of catch-up growth during follow-up at the 40thgw, and at the 6th, 12th and 18th months was lower than that of appropriate for gestational age newborns.</p>
