“…On the other hand, Ornelas et al 49 found that the extrauterine growth rates of premature small for gestacional age and appropriate for gestational age infants differ and that small for gestational age infants have less inclined growth curves than appropriate for gestational age until the fortieth week. Ehrenkranz et al 50 reported that appropriate for gestational age infants and infants who did not develop severe morbidities had higher growth rates.…”

Objective: To analyze the growth rate of premature infants in the first weeks of life and factors associated with extrauterine growth restriction. Methods: This is a cross-sectional study of 254 premature infants in a neonatal intensive care unit conducted from January 1, 2008 to December 31, 2010. Infants who died or had malformations incompatible with life were excluded. Median weight curves according to gestational age were constructed for the first four weeks of life. The Fenton growth chart calculations provided the weight Z-scores. Extrauterine growth restriction was defined as corrected weight-for-age Z-score ≤-2. Perinatal, morbidity, and health care variables were analyzed. The Poisson regression model yielded the prevalenceratios . Associations between extrauterine growth restriction and the perinatal, morbidity, and care variables were investigated. Poisson regression controlled possible confounding factors. Results: The frequency of extrauterine growth restriction was 24.0%. Most (85.0%) small-for-gestational-age infants developed extrauterine growth restriction; 55.3% of extrauterine growth restriction cases involved small-for-gestational-age infants. Premature infants with gestational age >32 weeks did not recover the median birth weight until the third week of life and had a higher frequency of small-for-gestational-age. The Z-scores of non-small-for-gestational-age infants decreased more after birth than those of small-for-gestational-age infants. extrauterine growth restriction was associated with small-for-gestational-age (PR=6.14; 95%CI=3.33-11.33;p <0.001) and time without enteral diet (PR=1.08; 95%CI=1.04-1.13; p =0.010). Conclusion: Extrauterine growth restriction occurs in premature infants of all gestational age. The participation of small-for-gestational-age and nutritional practices in its genesis is noteworthy. We suggest prospective studies of all premature infants. The implementation of best care practices, individualized for small-for-gestational-age infants, to improve nutrient supply can minimize the problem.

“…29 With special regard to weight, 21 Counts model reliably shows the changes that occur during the growth of preterm newborns: 30 weight loss, which occurs in the first week of life (range of 4 to 5 days) in all curves; birth weight recovery, which occurs between the second and third weeks (range of 16 to 19 days) and weight gain. Somatic growth dynamics is graphically similar for all birth weight categories.…”

Objective: To assess the somatic growth of preterm newborns through growth curves during the first 12 weeks of life.Method: A longitudinal and prospective study was carried out at two state operated maternity hospitals in the city of Belo Horizonte. Three hundred and forty preterm infants with birth weight less than 2,500 g were weekly evaluated in terms of body weight, head circumference, and height. Growth curves were constructed and adjusted to Counts model. Results:Counts model clearly showed that the dynamics of loss, stabilization and gain of weight of all curves are graphically similar. The growth curve was characterized by weight loss during the 1st week (4-6 days) ranging from 5.9 to 9.7% (the greater the percentage, the lower the birth weight). For all curves, recovery of birth weight ranged from 16 to19 days, showing that these newborns took longer to recover their birth weight. After the 3rd week, the newborns maintained increasingly rates of weight gain. Head circumference and height curves are little affected by weight loss. However, newborns with low birth weight presented loss of head circumference and height, probably due to their lower gestational ages. Conclusion:The dynamics of the preterm infants evaluated was similar to that of previous studies. The infants also presented growth deficit. However, it was also noted that the infants present a high potential to recover their growth.

“…É importante considerar que, para a população de recém-nascidos pequenos para a idade gestacional, houve dois períodos diferentes de coleta de dados, mas as características das duas amostras foram semelhantes, conforme demonstrado nas Tabelas 1 e 2, o que nos permitiu o agrupamento dessas duas populações. Comprimento (cm) Um dos aspectos interessantes da metodologia deste trabalho foi encontrar, entre os diferentes modelos matemáticos que fazem o ajustamento dos dados, o modelo de Count, que inicialmente foi estudado através do trabalho de Anchieta 22 e, posteriormente, reaplicado no trabalho de Ornelas 29 . O modelo de Count, principalmente para o peso 21 , capta de forma fidedigna as alterações que ocorrem durante o crescimento dos RNPT 30 : o período de perda de peso, que, para todas as curvas, encontra-se na primeira semana de vida (variando de 4 a 5 dias); o período de recuperação do peso de nascimento, que ocorre entre a segunda e terceira semana (variando de 16 a 19 dias); e o período de ascensão do peso.…”
