Neonatal growth charts

Abstract

The ability to recognize abnormal growth at birth and/or an intrauterine malnutrition is of great importance for neonatal care and prognosis. The current gold standard in neonatal auxological evaluation is based on information obtained from both neonatal anthropometric charts and intrauterine growth charts. Numerous charts have been proposed, but they are hardly comparable with each other, due to numerous methodological problems. The Italian Society of Neonatology, the Italian Society of Pediatric Endocrinology and Diabetology and the Italian Society of Medical Statistics and Clinical Epidemiology promoted a multicenter survey with the aim to produce an Italian neonatal anthropometric reference (Italian Neonatal Study [INeS] charts) fulfilling the set of the criteria that a reliable neonatal chart should possess. In clinical practice neonatal charts have some limitations if they are used to monitor postnatal growth of preterm newborns from birth to term. To overcome the problems related to the construction and use of a reference, an international project has recently started a study aiming to create prescriptive standard for the evaluation of postnatal growth of preterm infants (INTERGROWTH-21st). While an international longitudinal standard for evaluating preterm infant postnatal growth is lacking, in Italy the best compromise is likely to be as follows: new INeS charts up to term; International longitudinal charts WHO 2006 or CDC 2002 from term to 2 years; finally, the Italian Society for Pediatric Endocrinology and Diabetes (SIEDP) growth charts could be suitable for monitoring the growth of these infants from 2 years up to 20 years of age.

Delayed Cord Clamping Increased the Need for Phototherapy Treatment in Infants With AB0 Alloimmunization Born by Cesarean Section: A Retrospective Study

“…Starting and stopping of phototherapy was retrospectively reviewed by the authors to minimize possible errors in data collection, arising from protocol violations during clinical practice. Clinical and biochemical data collection included: sex, GA, birth-weight, small for gestational age < 3rd percentile according to Bertino's growth charts (9), weight loss (percentage), type of feeding (exclusive breastfeeding, mixed or bottle feeding), East Asian race, and cephalohematoma or significant bruising. We collected the first bilirubin concentration, the bilirubin concentration at Newborn Screening (NS), between 48 and 72 h after birth, the maximum bilirubin concentration, and the hours of life at each determination.…”

Avaliação do crescimento de crianças: a trajetória das curvas de crescimento

“…Curvas mais específicas para as várias fases da infância já estão sendo desenvolvidas, 31 de acordo com o peso ao nascer 32 e o crescimento intrauterino. 33 Assim, paradoxalmente à demanda de um único instrumento internacional, caminhamos a passos pouco mais lentos e discrepantes para a especificidade: cada país com sua curva de crescimento infantil própria.…”

“…23,[25][26][27][28]30 Indo além, alguns recomendam sua utilização apenas em crianças com aleitamento materno exclusivo nos primeiros meses de vida, haja vista as diferenças significativas dos parâmetros antropométricos entre a referência da OMS e outras. 31 Por outro lado, é bastante evidenciado na literatura que o crescimento até os cinco anos de idade sofre baixa influência genética. 3,5,7,8,10 O uso de curvas locais não tem sido encorajado pelas principais organizações e instituições do mundo, sobretudo pelas dificuldades técnicas e políticas.…”
