Evaluation Techniques

The infant who is small for gestational age (SGA) is more mature at birth than similar weight infants who are appropriate for gestational age (AGA). Whether the SGA infant behaves as does the larger gestationally equivalent infant, or whether there are specific changes related to intrauterine growth retardation is a matter of some interest in the understanding of the special needs of these infants. The National Institute of Child Health and Human Development (NICHD) phototherapy study provided a large newborn population for whom birth weight, gestational age at birth, and, thereby, intrauterine growth were carefully assessed. Infants who weighed 2,000 g or more at birth were included in the study only when they became jaundiced, whereas infants who weighed less than 2,000 g at birth were routinely entered into the study. Consequently, this report will be limited to the lowbirth-weight population selected by birth weight. Too few SGA babies were present in the groups with greater birth weight to allow meaningful comparisons. PATIENT SELECTIQN All infants whose birth weight was less than 2,000 g were entered into the study at 24 ± 12 hours. Those excluded from the study were: (1) infants who died before 24 hours, (2) infants with serious congenital defects, and (3) infants whose mothers refused consent for study. The study population consisted of 922 infants surviving at 24 hours. Gestational age was calculated from the first day of the last menstrual period obtained from maternal history and also by the evaluation techniques of Dubowitz.25 Intrauterine growth was determined by plotting birth weight and gestational age on the Denver Intrauterine Growth Curves8; infants below the 10th percentile were considered SGA.

Serum Gh

Recent investigations have raised the possibility that growth hormone (GH) influences intra-uterine weight and length. Moreover, the hypoglycemic tendency of small for gestational age (FSGA) infants and their small size could result from GH deficiency. To verify these hypotheses, a prospective study of daily serum GH and glucose levels was conducted in 46 newborn infants, including 18 FSCA infants, 18-full-term, appropriate for gestational age (FAGA), and 10 premature (PR) infants. Two FSGA babies became hypoglycemic. Both manifested normal GH competence as evidenced by normal daily GH levels, adequate GH response to arginine provocation, and satisfactory growth for over 2 years. Eleven of 12 FSGA babies followed from 14 to 26 months showed no evidence of impaired linear growth. The FSGA babies had GH values similar in magnitude and pattern to those of FAGA and PR infants. During the second half of the first postnatal day, a significant rise in serum GH occurred in all infants regardless of their size or gestational age; this rise may be the result of the stimulating effect of early milk feedings. GH deficiency does not appear to contribute to either the small size or hypoglycemic tendency of FSGA newborn infants.

The purpose of this study was to compare the behavior of full-term small-for-gestational age (SGA) with full-term appropriate-for gestational age (AGA) infants in the first year of life. We prospectively evaluated 68 infants in the 2nd month, 67 in the 6th month and 69 in the 12th month. The Bayley Scales of Infant Development-II were used, with emphasis on the Behavior Rating Scale (BRS). The groups were similar concerning the item “interest in test materials and stimuli”; there was a trend toward differences in the items “negative affect”, “hypersensitivity to test materials” and “adaptation to change in test materials”. The mean of Raw Score was significantly lower for the SGA group in the items “predominant state”, “liability of state of arousal”, “positive affect”, “soothability when upset”, “energy”, “exploration of objects and surroundings”, “orientation toward examiner”. A lower BRS score was associated with the SGA group in the 2nd month.

PurposeThe aim of this study was to assess morbidity and mortality pattern of small for gestational age (SGA) preterm infants in comparison to appropriate for gestational age (AGA) preterm infants of similar gestational age.MethodWe compared neonatal outcomes of 1336, 1:1 matched, singleton SGA and AGA preterm infants based on their gestational age using data from the study ‘Causes of Illness and Death of Preterm Infants in Ethiopia (SIP)’. Data were analysed using SPSS V.23. ORs and 95% CIs and χ2 tests were done, p value of <0.05 was considered statistically significant.ResultThe majority of the infants (1194, 89%) were moderate to late preterm (32–36 weeks of gestation), 763 (57%) were females. Male preterm infants had higher risk of being SGA than female infants (p<0.001). SGA infants had increased risk of hypoglycaemic (OR and 95% CI 1.6 (1.2 to 2.0), necrotising enterocolitis (NEC) 2.3 (1.2 to 4.1), polycythaemia 3.0 (1.6 to 5.4), late-onset neonatal sepsis (LOS) 3.6 (1.1 to 10.9)) and prolonged hospitalisation 2.9 (2.0 to 4.2). The rates of respiratory distress syndrome (RDS), apnoea and mortality were similar in the SGA and AGA groups.ConclusionNeonatal complications such as hypoglycaemic, NEC, LOS, polycythaemia and prolonged hospitalisation are more common in SGA infants, while rates of RDS and mortality are similar in SGA and AGA groups. Early recognition of SGA status, high index of suspicion and screening for complications associated and timely intervention to prevent complications need due consideration.

Objective: To describe the eruption chronology of the first deciduous teeth in premature infants with birth weight less than 1500g and to compare it according to gender and nutritional status at birth. Methods: Longitudinal study including 40 low birth weight premature infants of both genders. The tooth was considered erupted when the crown went through the gum and became part of the oral environment. The comparison of the eruption chronology in relation to gender and among children appropriate or small for gestational age was done by Student's t-test, being significant p<0.05. Results: The eruption of the first tooth (teeth) occurred, on average, with 11.0±2.1 months of chronological age and with 9.6±1.9 months corrected for prematurity. The first erupted teeth were the lower central incisors. The average eruption for males was 9.7±1.9 and, for females, 9.5±1.9 months, both corrected for prematurity (p=0.98). The average eruption in children with birth weight appropriate for gestational age was 10.1±1.4 months; for small for gestational age, it was 9.4±2.2, also corrected for prematurity (p=0.07). Conclusions: The average eruption age of the first teeth, corrected for prematurity, was 9.6 months. Sex and nutritional status at birth did not change the eruption chronology.

Groups of healthy, small-for-gestational age (SGA) and preterm appropriate-for-gestational age (AGA) infants were studied at birth, 1 month, 3 months, and 12 months of age. Serum thymic hormone (TH) activity was assayed, the number of T lymphocytes in the peripheral blood was counted, and in vitro lymphocyte stimulation responses to phytohemagglutinin (PHA) were evaluated. TH activity was decreased in 1-month-old SGA infants. T cells were reduced in all low birth weight infants; the number reverted to normal by 3 months of age in preterm AGA infants, whereas it remained low for at least 12 months in the SGA group. Lymphocyte stimulation response was decreased in low birth weight infants; the extent of depression paralleled reduction in T lymphocyte number. These observations indicate that cell-mediated immunity is impaired in low birth weight newborns and reduced TH activity may be one of the pathogenetic factors involved. Persistent depression of immunocompetence may underlie the increased susceptibility of SGA infants to infection-related morbidity and mortality.

The Impact

Objective. Small-for-gestational age (SGA) infants born with intrauterine growth retardation (IUGR) differ from appropriate-for-gestational age (AGA) infants by: a) alterations in a number of neurologic and neurophysiologic characteristics; b) modified heart rate variability during the neonatal period; and c) increased morbidity rates during the first months of life. However, there are no data on the impact of IUGR on respiratory function control at birth. Methods. We studied 57 newborns who were 35 to 36, 37 to 38, and 39 to 41 weeks' conceptional age (CA): 31 were AGA and 26 were SGA. All were clinically and neurologically normal at birth and none exhibited abnormal events during the first year of life. Polygraphic recordings were performed between two meals during the normal postnatal stay in the maternity ward. Results. During both active sleep (AS) and quiet sleep (QS), SGA infants in all CA groups had significently higher values for the incidence of 2 to 4.9 seconds and 5 to 9.9 seconds central respiratory pauses (RP), the apnea index (AI) [AI = % of nonbreathing time], and the time spent with periodic breathing (PB), as compared with AGA infants Respiratory frequency was usually similar in SGA and AGA infants. In addition, the trend of age-related respiratory modifications was disturbed in SGA infants, as compared with AGA infants: at 39 to 41 weeks CA, SGA infants had no significant decreases in RP, AI, or PB, and no increase in respiratory frequency. However, between-state differences were similar in both groups. In all AGA and SGA infant groups respiratory frequency seemed to be an individual characteristic: infants who breathed faster during AS breathed faster during QS, and vice-versa. Conclusion. Our data demonstrate significant modifications in the establishment of respiratory rhythm control in SGA infants, whereas the patterns of state-related and subject-dependent breathing characteristics were similar in SGA and AGA infants. We speculate that the dysregulation of respiratory function control maturation observed in healthy SGA infants may be related to subtle brainstem modifications attributable to the decreased blood supply and chronic hypoxia associated with IUGR.

The Impact

The aim of this study was to evaluate leptin concentration at birth and in early postnatal life in small- and appropriate-for-gestational-age infants and to assess its relationship with infants’ anthropometry at birth and some characteristics of maternal pregnancy. Materials and methods. A total of 367 infants born after 32–42 weeks of gestation were enrolled in the study. Umbilical cord blood samples were collected from 80 small- and 287 appropriate- for-gestational-age newborns. Altogether, 166 venous blood samples were taken from these neonates on days 2–6 of life. Results. Cord leptin levels were significantly lower in small- compared to appropriate-forgestational- age infants. We observed a positive correlation between cord leptin and birth weight, all neonatal anthropometric parameters, placental weight, and some maternal nutritional factors. In multivariate analysis, cord leptin concentration explained up to 15% of the variation in sum of newborn’s skinfold thickness but only 5% of the variation in birth weight. Postnatally, leptin concentration decreased markedly to the similar low levels in both infant groups and remained so during the first postnatal week. Conclusions. Significantly lower cord leptin concentration in small-for-gestational-age neonates reflects a lower fat mass content compared to appropriate-for-gestational-age infants. However, an abrupt decrease in leptin levels shortly after birth in both groups suggests that placenta could be an important source of leptin in fetal circulation. The impact of low leptin levels at birth in small-for-gestational-age infants on their postnatal appetite and weight gain remains to be elucidated in future studies.
