Frequently Asked Questions About the CDC Growth Charts Development Neonatal Research Network Centers (Ehrenkranz, ). The revised Fenton Preterm Growth Chart harmonized a very large of the charts, possibly outdated, as the Ehrenkranz chart [8]. Ehrenkranz RA(1), Younes N, Lemons JA, Fanaroff AA, Donovan EF, Wright LL, BACKGROUND: The interpretation of growth rates for very low birth weight.

Moreover, it seems that tape was used for measuring the length in the survey by Olsen et al.

Is intrauterine growth appropriate to monitor postnatal growth of preterm neonates?

Neural Exam – Newborn head circumference. Both authors have given final approval of the version to be published. Formula fed infants gain weight more rapidly after about 3 months of age. The clinical charts are available from the Clinical Growth Charts page and can be downloaded and copied. Nutritional practices common during the chrt 20 years, such as the mean caloric and protein intake provided, have also been shown to correlate with growth.

The original program can also be ggowth at http: Postnatal use of intrauterine growth data The American Academy of Pediatrics [ 3 ] and the Canadian Pediatric Society [ 4 ] recommend that preterm infant growth should approximate intrauterine growth, with the argument that the fetus is not affected by extrauterine factors with negative impact on the nutrition status and growth, growrh as suboptimal nutrition support, major neonatal complications and medical interventions that increase energy expenditure and nutrient losses [ ehrenkrranz ].

What charts should be used for special populations? Of most importance is making accurate length measurements of infants being monitored in the NICU, so that the growth trajectory of the individual infant can be accurately assessed. We agree that this loss cannot be readily accounted for in intrauterine growth data.

Anthropometric measures body weight, length, head circumference, and midarm circumference were performed from birth until discharge, transfer, death, age days, or a body weight of g. In most cases, Body Mass Index BMI -for-age charts are not available for special conditions and have not been validated to use with children whose body composition might differ from that of typical children.

Postnatal growth failure

Received May 22; Accepted Dec 6. Longitudinal growth of hospitalized very low birth weight infants. Attempting fhart mimic intrauterine growth in early postnatal life may be achieved with excessive increase in fat mass, predisposing to obesity and late metabolic syndrome [ 10 ]. Existing growth charts for children aged years were based on a nationally representative sample, but charts for those up to chwrt 2 were based on a study since shown to have several limitations, said Dr.

The systematic errors due to tone near term age are likely similar between the reference curves and neonatal intensive care measurements.

J Matern Fetal Neonatal Med. The new charts are suitable for all ethnic groups and set breast ehrenkrans as the norm. Comparison of these five charts reveals surprisingly large differences that are for the most part unexplained. Early aggressive nutritional management for very low birth weight infants: American Academy of Pediatrics. Large, multicenter, prospective cohort study.

What is a percentile? Variables associated with extrauterine growth restriction in very low birth weight infants. Existing postnatal growth references do not provide guidance about the importance of any deviations from the mean of the reference sample.

Can a meta-analysis that mixes apples with oranges be used to demonstrate that levosimendan reduces mortality after coronary revascularization? Growth in weight, recumbent length, and head circumference for preterm low-birthweight infants during the first three years of life using gestation-adjusted ages. Random errors are likely introduced due to imperfect measurement techniques such as using a tape measure and measurements made without a length-boardas well as some systematic errors, due to normal flexor posture of term and near-term infants.

A copy of the program is included on the Embryology CD. It is likely that identification of PGF for preterm infants has led to increased attention to, and perhaps better achievement of, recommended nutrient intakes with subsequent improved growth patterns and development. At present, the available postnatal longitudinal growth charts for preterm infants are essentially a descriptive reference, accounting for the physiologic postnatal water loss, but influenced by nutrition practices contemporary to the construction of the charts, possibly outdated, as the Ehrenkranz chart [ 8 ].

What growth charts are appropriate to use with exclusively breastfed babies? Efforts during the past ten to 15 years to develop standardized feeding guidelines have begun to show some success in reducing the incidence of EUGR. However, at hospital discharge, most infants born between 24 and 29 weeks of gestation had not achieved the median birth weight of the reference fetus at the same postmenstrual age.


Dewey worked on–the Davis Area Research on Lactation, Infant Nutrition, and Growth study–found that breastfed babies generally weighed less in their first year because they voluntarily took in less milk than did formula-fed babies.

Luis Pereira-da-Silva 1 and Daniel Virella 1. Meco M, Cirri S. Accessed November 26, Such guidelines provide intense nutritional support through a combination of early parenteral nutrition and early enteral nutrition, followed by a progressive reduction of parenteral nutrition, as enteral feeding volumes are steadily advanced to full enteral nutrition.

Is intrauterine growth appropriate to monitor postnatal growth of preterm neonates?

Individual data should be interpreted with caution when plotting crown-heel length on charts based on original measurements that have been obtained without the recommended technique. Use of a body proportionality index for growth assessment of preterm infants.

The Fenton Chart represents reference curves closer to normative standard, considering that reference charts describes how growth actually is, while standard indicates how growth should be [ 2 ].

Catch-up growth, muscle and fat accretion, and body proportionality of infants one year after newborn intensive care. Dewey, associate director of the Program in International Nutrition and professor of nutrition at the University of California, Davis. Neonatal length inaccuracies in clinical practice and related percentile discrepancies detected by a simple length-board.

These specialized growth charts provide useful growth references, but may have some limitations. Pereira-da-Silva and Virella expressed valid concerns regarding the differences between the growth pattern of preterm infant and that of intrauterine growth, particularly during the first postnatal weeks, due at least in part to the postnatal physiologic weight loss. Therefore since random errors vary in both directions of over- and underestimation, the random errors in large population-based surveys are likely to provide an unbiased result.

They should not be taken as optimal.
