Aim: Previous studies have shown visual evoked potential (VEP) abnormalities in infants and animals born small for gestational age (SGA) compared with controls. The current exploratory study aims to investigate whether VEP abnormalities persist in older ages. Methods: Pattern VEP latencies were obtained in 21 children (11 girls, 10 boys), born SGA and moderately preterm, at an average age of 5 years and 8 months. Fifty‐one children (24 girls, 27 boys, mean age of 5 years and 7 months), also born moderately preterm but with normal height and weight at birth, served as controls Results: Visual evoked potential results showed no significant differences in latency between children born SGA and controls born appropriate for gestational age (AGA) for either binocular stimulation, right eye or left eye stimulation. Conclusions: Our findings do not indicate any differences in VEP latency at preschool age for children born SGA compared with children born AGA. The results may support previous studies, suggesting that children born SGA show accelerated neurophysiologic maturation during their first year of life and that previously delayed VEP latencies after catch‐up stay unchanged compared with controls. 相似文献

Postnatal growth was prospectively measured from birth to 1 y in 54 term infants born small for gestational age (SGA), fed either breast milk or a standard term infant formula. Breastfeeding was associated with a 0.36 and 0.64 standard deviation (SD) increase in weight at 2 weeks and 3 months of age. respectively, which persisted beyond the breastfeeding period (0.64 SD at 1 y). Breastfed infants also showed greater catch-up growth in head circumference [SD score (SDS) 0.53 higher at 3 months], and greater body length gain (SDS 0.68 higher at 6 months). This increased growth was independent of potentially confounding obstetric, social and demographic factors. Our findings suggest that breastfeeding may promote faster growth in infants compromised by poor growth in utero. SGA infants may be programmed for a number of adverse outcomes; the possibility that such events are altered by choice of postnatal diet is a key issue for future research. 相似文献

Postnatal growth was followed in a population-based group of 123 small-for-gestational-age (SGA, birth weight < -2 SD) children (66 boys and 57 girls) to four years of age in order to determine the incidence and time of catch-up growth. Gestational age was determined by ultrasound in gestational weeks 16–17 in all pregnancies, thus eliminating the problem of distinguishing between SGA and preterm infants. Infants with well-defined causes for slow growth rate, i.e. those infants with chromosomal disorders, severe malformations, intrauterine viral infections or cerebral palsy, were excluded. The boys showed an extremely fast weight catch-up, 85% of them reaching weights greater than -2 SD at the age of three months and remaining above this level to the end of the study period. Such a fast catch-up growth was observed in only two-thirds of the girls, but at four years of age 85?4 of the girls were also above -2SD. Length catch-up was more gradual than weight catch-up. Of the boys, 54% had lengths below -2 SD at birth, 26% at 1 year of age, 22% at 2 years of age, 17% at 2.5 years of age and 11% (n= 8) at 4 years of age. Corresponding figures for girls were: 69% at birth, 28%) at 1 year, 15% at 2 years, 12% at 2.5 years and 5%) (n = 3) at 4 years. At 4 years of age, only six boys and three girls remained below -2 SD for both weight and height. We conclude that in Sweden the prognosis for catch-up growth for an SGA child, when children with well-defined causes of growth disturbances are excluded, is very good and it is extremely rare for the child still to have a height below -2 SD by the age of 4 years. 相似文献

Children born small for gestational age (SGA) have an increased risk of cardiovascular disease (CVD) and associated risk factors in later life; however, little is known about their dietary intakes. The objective of this study was to assess dietary intakes in SGA and appropriate for gestational age (AGA) at 3.5, 7, and 11 years. The Auckland Birthweight Collaborative Study is a longitudinal case–control study of children born at term (n = 871). Children were assessed at 3.5 (n = 550), 7 (n = 591), and 11 (n = 620) years of age. Diet was assessed using a 24‐hr record‐assisted recall. Reported dietary intakes were analyzed and compared with the Australian and New Zealand Nutrient Reference Values. Compared with AGA, median energy intakes were significantly lower in SGA at 3.5 years (4.2 MJ [IQR, 3.0 to 5.8] vs. 5.4 MJ [IQR, 3.9 to 6.5]; p < .0001) but not at 7 and 11 years. Inadequate dietary intakes of micronutrients were more prevalent among SGA at 3.5 years and 11 years of age. A large proportion of SGA and AGA children consumed more than the recommended amounts of saturated fats, sugars, and sodium. There was no association of dietary intake and socio‐demographic factors. This study reveals that dietary intake in 3.5‐year‐old children born SGA is lower in energy and a variety of micronutrients compared with dietary intake in AGA. These intakes may however be appropriate given their BMI z‐scores. High intakes of sodium, saturated fat, and sugars are a concern for all children in this cohort. 相似文献

??Objective??To find the difference in growth and development of children between full-term symmetric growth restriction??FSGR?? and full-term asymmetric growth restriction??FAGR?? through a general investigation of children born small for gestational age in Shanghai. Methods??This general investigation covered all children under 6 years old in Shanghai. Data on growth were retrospectively obtained from medical records. The P10 of birth head circumference/birthweight of the same gestational age and gender was used to distinguish FSGR and FAGR. Results??The sample contained 10 188 full-term SGA children among whom 8049 were FAGR and 2139 were FSGR. Up to 3 years old??both FSGR and FAGR failed to catch up in weight??height??head circumference and chest circumference. Growth restriction in FAGR was more serious. Significant difference could be seen in weight??t??-3.412??P??0.001?? and chest circumference??t??-2.526??P??0.012?? between FSGR and FAGR at 3 years old. Regarding growth speed??the growth rate of weight ??t??6.272??P??0.001????height ??t??9.143??P??0.001????head circumference ??t??6.063??P??0.001?? and chest circumference ??t??6.617??P??0.001?? were higher in FAGR 6 months after birth??while there was no difference after that. The BMI of FAGR was significantly lower than FSGR before 2 years old. The proportion of children in danger of being overweight was significantly higher in FSGR ??P??0.001??. Conclusion??Both FSGR and FAGR experience catch-up growth after birth??but not enough to catch up with normal children at 3 years old??especially in head circumference. In spite of severer growth restriction??the cath-up growth model of FAGR is superior to FSGR. The proportion of children in danger of being overweight is significantly higher in FSGR. 相似文献

OBJECTIVE: We analyzed postnatal growth in children with familial short stature (FSS) with regard to small (SGA) or appropriate (AGA) for gestational age status at birth. STUDY DESIGN: We studied 96 otherwise healthy short-statured children (58 males; SGA: n = 41, AGA: n = 55). At least one of the parents was short-statured. Cross-sectional data for length/height and weight for the first 4 years of age were collected retrospectively. RESULTS: AGA children had a mean length of 0.09 +/- 1.02 standard deviation score (SDS) at birth, -1.57 +/- 1.16 SDS after 1 year of age, and -2.36 +/- 0.72 SDS after 4 years. SGA children had a mean length of -2.04 +/- 1.06 SDS at birth, -2.70 +/- 1.12 SDS at 1 year of age, and -3.05+/-0.86 SDS at 4 years. The loss of length SDS within the first 2 years of life was greater in AGA than in SGA children. SGA children were significantly shorter than AGA children at all of the study points (p <.001). CONCLUSIONS: Children with an FSS background born AGA show catch-down growth to their lower familial range during the first 2 years of life. SGA children did not catch up to their AGA peers at any time. 相似文献

Background
Although both very preterm (VP) and small for gestational age (SGA) births are suggested to increase the likelihood of childhood emotional problems, there has been a lack of research comparing these effects.Aims
To investigate levels of emotional problems between 6–13 years of age and contrast the impact of being born either very premature (irrespective of birth weight) or small for gestational age.Study design
Prospective longitudinal cohort study.Subjects
654 Bavarian children (born 1985–1986) who were followed from birth to age 12/13 years.Outcome measures
Emotional problems at ages 6.3 and 8.5 years were measured via the Child Behavior Check List (CBCL). Emotional problems were measured at age 12/13 years via the Strengths and Difficulties Questionnaire (SDQ). Trajectories of emotional problems were derived between 6.3 and 13 years.Results
Two distinctive patterns of age 6–13 year emotional problems were found: 1) a low and stable level of problems in 76% of children; 2) a high and stable level of problems in 24% of children. The high and stable pattern of emotional problems was significantly associated with a VP but not an SGA birth. Consistent additional determinants included male child gender and lower family socioeconomic status.Conclusions
The disparity between VP and SGA births as a predictor of age 6–13 year old emotional problems is considered in terms of fetal and/or glucocorticoid programming. The stability of emotional problems between 6 and 13 years reinforces the need for early childhood interventions aimed at children born very preterm. 相似文献17.

The body composition of 70 appropriate for gestational age newborn infants whose gestational age ranged from 32 to 41 weeks was determined by dual-energy X-ray absorptiometry during the first 48 h of life. The evolution of the bone mineral content, fat and lean mass was well correlated with gestational age ( r = 0.66, r = 0.66 and r = 0.82. respectively) but even more closely with birthweight ( r = 0.85, r = 0.91 and r = 0.97. respectively). The body composition of 20 symmetric small for gestational age infants (mean gestational age ± SD = 38.1 ± 1.2 weeks: mean birthweight ± SD = 2117 ± 183 g) was also studied. The total body fat, the lean mass and the bone mineral content of small for gestational age infants were decreased significantly in comparison with those of appropriate for gestational age infants with the same gestational age ( p ≤ 0.05, p ≤ 0.0001 and p ≤ 0.05) but was not significantly different from those observed in appropriate for gestational age infants of the same birthweight. 相似文献

AIMS: To assess the effect of maternal smoking and environmental tobacco smoke (ETS) on risk of small for gestational age infants (SGA). METHODS: Case-control study of 844 cases and 870 controls. RESULTS: Maternal smoking in pregnancy was associated with an increased risk of SGA (adjusted odds ratio (OR)= 2.41; 95% confidence interval (CI) = 1.78, 3.28). We could not detect an increased risk of SGA with paternal smoking, or with other household smokers when the mother was a non-smoker, but did find an increased risk with exposure to ETS in the workplace or while socializing. Infants of mothers who ceased smoking during pregnancy were not at increased risk of SGA, but those who decreased but did not stop remained at risk of SGA. There was no evidence that the concentration of nicotine and tar in the cigarettes influenced the risk of SGA. CONCLUSIONS: Maternal smoking in pregnancy is a major risk factor for SGA. This study suggests that mothers should be advised to cease smoking completely during pregnancy, and that a reduction in the number of cigarettes smoked or smoking low tar or nicotine concentration cigarettes does not reduce the risk of SGA. 相似文献
