Frequency and risk factors for the birth of small-for-gestational-age newborns in a public maternity hospital

Abstract

Objective:To determine the frequency and risk factors of small-for-gestational-age newborns in a high-risk maternity.Methods:This is an observational, cross-sectional, and case-control study, conducted in a public tertiary care maternity hospital. Data from 998 newborns and their mothers were collected through interviews and review of medical records and prenatal care cards. Some placentas underwent histopathological analysis. The variables of small-for-gestational-age and non-small-for-gestational-age newborns and of their mothers were statistically compared by means of Student's t test, Fisher's exact test, and odds ratio. The significance level used was 0.050.Results:There was a 17.9% frequency of small-for-gestational-age newborns. The statistically significant factors associated with the birth of these babies were female sex (p=0.012); positive history of another small-for-gestational-age child (p=0.006); inadequate prenatal care (p=0.019); smoking (p=0.003); hypertensive disorders of pregnancy (p=0.007); placental bleeding (p=0.009) and infarction (p=0.001).Conclusion:In the population studied, the frequency of small-for-gestational-age newborns was high and associated with sex, inappropriate prenatal care, presence of maternal diseases and addictions, and placental abnormalities.

Adequação do peso ao nascer para idade gestacional de acordo com a curva INTERGROWTH-21 st e fatores associados ao pequeno para idade gestacional

“…Mesmo com outras curvas de crescimento, há poucos estudos nacionais recentes avaliando prevalência e fatores associados ao RN-PIG, destacando-se a coorte de Pelotas e um estudo em São Paulo 14,15 .…”

“…O estudo de Teixeira ocorreu em uma maternidade pública terciária da cidade de São Paulo, que atende à população de muito baixa renda. A curva de Alexander et al 11 foi aplicada a 998 RN em 2014, e foram identificados 179 RN (17,9%) abaixo do percentil 10 dessa curva 15 .…”

“…No Brasil, são poucos os estudos recentes avaliando tanto a prevalência como os fatores associados ao pequeno para idade gestacional [14][15][16] . Poucos estudos 16,17 , até o momento, utilizaram a curva INTERGROWTH-21 st para estimar adequação peso/idade gestacional.…”
