Standards for Birthweight at Gestation Periods from 32 to 42 weeks, Allowing for Maternal Height and Weight

Abstract

. (1970). Archives of Disease in Childhood, 45, 566. Standards for birthweight at gestation periods from 32 to 42 weeks, allowing for maternal height and weight. Standard charts are given for assessing the normality of birthweight for length of gestation from 32 to 42 weeks; first-born and later-born infants are shown separately, and allowance is made for maternal height and mid-pregnancy weight.

Effects of a dairy product fortified with multiple micronutrients and omega-3 fatty acids on birth weight and gestation duration in pregnant Chilean women

“…Infants were dried and weighed on an electronic self-calibrating scale immediately after delivery, either a Tanita 1583 electronic scale accurate to 10 g or a Seca 345 electronic scale accurate to 20 g. Crown-heel length was measured on a custommade neonatometer, and head circumference was measured with an insertion tape, both to the nearest mm. Adequacy of size for gestational age was estimated using the Aberdeen standard 17 . Newborns below the 10th percentile were classified as foetal growth-restricted (FGR) infants.…”

Individual correction of birth weight for parental stature with special reference to small-for-date and large-for-date infants

“…From these relationships, several authors have attempted to correct birth weight taking into account maternal stature, either using tables [2] or charts [5]. However it is not possible to decide if, or how, any corrective factor should be used, independently of the further utilizationof the corrected weight.…”

Utilização de uma curva de crescimento intra-uterino corrigido para peso e altura maternos

“…Neste trabalho pretende-se mostrar a validade da utilização da curva de Como se vê, os nossos resultados são semelhantes aos obtidos por Tanner e Thomson 5 , porém em geral abaixo daqueles valores. Com a inclusão de um nú-mero maior de casos é possível que parte dessa diferença desapareça.…”

“…uma vez que Tanner e Thomson 5 consideram apenas a idade em semanas completas, ou seja, toda criança nascida com idade gestacional de 37 semanas até 37 semanas e 6 dias, ao passo que nós consideramos as crianças de 37 semanas e 5 dias como de 38 semanas, Assim, parte de nossos casos que, de acordo com Tanner e Thomson 5 deveria figurar numa dada idade, é computada sempre na semana seguinte, o que faz diminuir o peso médio ao nascer.…”
