“…Body composition (ie, fat and lean body mass), rather than the use of birth WT alone, provides important information about the general nutritional state of fetuses and neonates. 52,53 A logical step is to apply IGA to a soft tissue parameter that is rapidly and reliably measured in fetuses. Fractional arm or thigh volume appears to be especially suitable for this purpose.…”

Objective. The goals were to introduce fractional arm volume (AVol) as a new soft tissue parameter of fetal growth assessment and to develop individualized growth standards, based on Rossavik models, for AVol, midarm circumference (ArmC), and humeral diaphysis length (HDL). Methods. A prospective longitudinal study of 22 fetuses was conducted using 2-and 3-dimensional sonography. Three new growth parameters (HDL, ArmC, and AVol) were used to establish individualized standards for arm growth with the use of Rossavik functions [P = c(t), where P is the anatomic parameter; c, k, and s are model coefficients; and t is the time variable]. Second-trimester models were specified from the linear slopes of growth curves before approximately 28.0 menstrual weeks. For a given fetus, normal thirdtrimester trajectories were predicted for each parameter. Observed and predicted measurements were compared by percent deviations. Results. Rossavik functions fit all parameter trajectories extremely well (R 2 = 95.7%-99.4%). By fixing coefficients k at their mean values, their respective fits did not change, and the variabilities of both coefficients c and s were reduced. Coefficient c was also significantly related to second-trimester slope, as was s to c, for all 3 parameters (R 2 = 97.7%-98.7%; P < .0001). Mean percent deviations between observed and predicted third-trimester HDL, ArmC, and AVol measurements were -0.1% ± 2.9%, 0.5% ± 4.6%, and 0.4% ± 8.5%, respectively. Conclusions. Individualized growth assessment, using HDL and ArmC, can accurately predict normal arm growth during the third trimester of pregnancy. AVol may also allow earlier detection and improved monitoring of soft tissue abnormalities that can occur in fetuses with growth disturbances.

“…Weight is a crude measure of nutritional status that cannot differentiate between thinness and shortness. 11,17 This article presents findings from a longitudinal study of 122 subjects born in Hong Kong in 1967. We investigated the associations between thinness and length at birth, changes in thinness and length between birth and 6 months of age and between 6 months and 18 months of age, and blood pressure at age 30 years.…”

Fetal Growth and Early Postnatal Growth Are Related to Blood Pressure in Adults

Abstract-It is commonly agreed that birth weight is associated with blood pressure in adults. However, not much is known about birth length, ponderal index, and early postnatal growth, whose effects on adult blood pressure, if any, can affect the interpretation of the birth weight-blood pressure association. This study examined the association between fetal growth, early postnatal growth, and blood pressure in Chinese adults. One hundred twenty-two subjects born in Hong Kong in 1967 were followed from birth to age 30 years. Multiple linear regression was used to analyze the association between size at birth, postnatal changes in body size, and systolic and diastolic blood pressure at age 30 years. Having adjusted for potential confounders and each other explanatory variable, it is found that birth length standard deviation score (regression coefficient or ␤ϭϪ3.2), ponderal index at birth (␤ϭϪ1.8), and postnatal changes in ponderal index from age 6 months to 18 months (␤ϭϪ2.2) were inversely associated with systolic blood pressure (each PϽ0.05). Postnatal changes in length standard deviation score were not significantly associated with systolic blood pressure. Birth length standard deviation score was inversely associated with diastolic blood pressure at age 30 years (␤ϭϪ2.6; PϽ0.05). Other anthropometric variables were not associated with diastolic blood pressure. The results support the hypotheses that both fetal growth and early postnatal growth may have a long-term impact on blood pressure in adults.It also highlights the importance of differentiating length and weight for length.

“…As críticas à utilização de um único critério para avaliação nutricional da criança ao nascer têm levado os pesquisadores a considerarem a utilização dos índices antropométricos e da aferição da prega cutânea como alternativa, dentro da antropometria nutricional, para uma avaliação mais acurada do estado nutricional do recém-nascido. Os índices mais freqüentemente estudados são aqueles que resultam da razão entre o peso e o comprimento (índice ponderal de Rohrer, índice de massa corpórea e razão peso/comprimento) e entre o perímetro braquial e o perímetro cefálico [2][3][4][5][6][7][8] .…”

Objective: an accurate assessment of the nutritional status of an infant at birth is very important, since it provides information on early identification of pathological events related to intrauterine growth acceleration or retardation. Anthropometric ratios such as weight/ length and mid-arm circumference/head circumference may be used as alternative tools for this purpose. The main objective of this study was to verify the correlation between triceps skinfold thickness with Rohrer Index, Body Mass Index, weight/length ratio, and mid-arm circumference/head circumference ratio.Methods: a cross-sectional study was carried out with 390 fullterm newborns delivered at the Maternity Ward of Instituto Materno Infantil of Pernambuco, from May to July 1999. The newborns had their birthweight, length, head and mid-arm circumferences and triceps skinfold thickness measured.Results: the results showed that among the anthropometric indices studied the weight/length ratio showed the strongest correlation with triceps skinfold thickness (r = 0.63, P< 0.001) followed by mid-arm circumference/head circumference ratio (r= 0.59, P< 0.001). Rohrer index showed the weakest correlation (r= 0.43, P< 0.001). Multiple linear regression analyses revealed that weight/length ratio correlated best with skinfold thickness.Conclusions: we concluded that among the studied indices, weight/length ratio showed to be the best alternative to assess the nutritional status of infants at birth.J Pediatr (Rio J) 2002; 78 (3): 219-24: itrauterine growth, anthropometric indices, skinfold thickness, nutritional assessment, weight/length ratio, mid-arm circumference/head circumference ratio. ResumoObjetivo: uma avaliação acurada do estado nutricional da criança ao nascer tem importância na identificação precoce de eventos mórbidos relacionados com a aceleração ou desaceleração do crescimento intra-útero. Os índices antropométricos resultantes das razões entre o peso e o comprimento e aqueles que resultam da razão entre o perímetro braquial e o perímetro cefálico podem ser uma alternativa, dentro da antropometria, para esse fim. O objetivo principal deste estudo foi verificar o grau de correlação entre a prega cutânea triciptal e os índices antropométricos -índice ponderal de Rohrer, índice de massa corpórea, razão peso/comprimento, razão perímetro braquial/perímetro cefálico -utilizados como critério de avaliação do estado nutricional de recém-nascidos.Métodos: realizou-se um estudo de corte transversal em 390 recém-nascidos a termo na maternidade do Centro de Atenção à Saúde da Mulher do Instituto Materno-Infantil de Pernambuco, no período de maio a julho de 1999. Os recém-nascidos foram avaliados quanto ao peso, comprimento, perímetros cefálico e braquial e prega cutânea triciptal.Resultados: os resultados mostraram que os índices antropomé-tricos apresentaram correlação significante com a prega cutânea triciptal, tendo sido a razão simples entre o peso e o comprimento aquele que se correlacionou mais fortemente (r = 0,63; p <0,001), seguido da...
