“…2). 1 In contrast to the similar weight-for-gestational age values for the RP-BRISA Cohort and other international growth curves, the average W/L ratios in the RP-BRISA Cohort infants were slightly greater (6.5 kg/m) than those of the most commonly used Fenton curves (∼5.6 kg/m) or the Intergrowth 21 st W/L growth curve values. 6 , 10 The reasons for the greater W/L ratios in the RP-BRISA Cohort infants are not known, but represent the primary limitation of W/L growth relationships, that unless weight and length are shown simultaneously, at any single gestational age or over time, one does not know whether a high or low W/L relationship is the result of higher or lower weights or longer or shorter lengths.…”

“…In this issue of the Jornal de Pediatria, Carlos Grandi and colleagues report anthropometric measurements made at birth, including weight/length (W/L) ratios and body composition estimates at birth, from a Brazilian cohort of “normal” preterm and term infants. 1 This was a large undertaking involving a cross-sectional analysis of data obtained from 7427 live-born neonates (3682 boys [49.6%] and 3745 girls [50.4%]) from the BRISA Cohort Study in the city of Ribeirão Preto, SP, Brazil in 2010. Infants with gestational ages ranging from ∼24 weeks to term were included, thus establishing fetal growth reference values for preterm infants in this population.…”

“…A ocorrência do aumento precoce, eleva o risco de obesidade na idade adulta(ABESO, 2016).Atualmente, a curva padrão para avaliação das medidas antropométricas ao nascimento são as curvas da Intergrowth 21st. Embora essas curvas tenham sido construídas com participação de recém-nascidos brasileiros,Grandi et al (2021), ao estudarem dados de nascimento da coorte BRISA (2010, dados somente de Ribeirão Preto), demonstraram que a razão peso/comprimento média dos neonatos de Ribeirão Preto era significativamente maios do que o valor médio da Intergrowth 21st(GRANDI et al, 2021). Isto significa que a curva padrão da Intergrowth 21st tem menor capacidade (sensibilidade) em identificar neonatos PIG ou wasted em Ribeirão Preto.Tendo em consideração o período de transição epidemiológica em que o Brasil se encontra, onde há o crescimento de síndromes metabólicas, que demandam tratamentos, juntamente com a mortalidade da população,Borges et al, 2018, observaram que é necessário identificar os fatores que possam ser marcadores para doenças crônicas não transmissíveis e síndrome metabólica nas populações de risco, como RN prematuros e com baixo peso ao nascer.…”
