“…This knowledge, in combination with the availability of specialized growth charts to track the growth of VLBW infants (24)(25)(26), led to the decision to exclude data for VLBW (< 1500 gm) infants from the revised infant growth charts.…”

Objectives-This report presents the revised growth charts for the United States. It summarizes the history of the 1977 National Center for Health Statistics (NCHS) growth charts, reasons for the revision, data sources and statistical procedures used, and major features of the revised charts.Methods-Data from five national health examination surveys collected from 1963 to 1994 and five supplementary data sources were combined to establish an analytic growth chart data set. A variety of statistical procedures were used to produce smoothed percentile curves for infants (from birth to 36 months) and older children (from 2 to 20 years), using a two-stage approach. Initial curve smoothing for selected major percentiles was accomplished with various parametric and nonparametric procedures. In the second stage, a normalization procedure was used to generate z-scores that closely match the smoothed percentile curves.Results-The 14 NCHS growth charts were revised and new body mass index-for-age (BMI-for-age) charts were created for boys and girls (http://www.cdc.gov/growthcharts). The growth percentile curves for infants and children are based primarily on national survey data. Use of national data ensures a smooth transition from the charts for infants to those for older children. These data better represent the racial/ethnic diversity and the size and growth patterns of combined breast-and formula-fed infants in the United States. New features include addition of the 3rd and 97th percentiles for all charts and extension of all charts for children and adolescents to age 20 years.Conclusion-Created with improved data and statistical curve smoothing procedures, the United States growth charts represent an enhanced instrument to evaluate the size and growth of infants and children.

“…The infants and children were also grouped by gestation-corrected age (GCA). 11,18,19 Gestation-corrected age was calculated as age in months, adjusted for length of gestation, using the following algorithm: for those born at 21 to 24 weeks' gestation, GCA = CA (in months) −4; at 25 to 28 weeks, GCA = CA (in months) −3; at 29 to 32 weeks, GCA = CA (in months) −2; at 33 to 36 weeks, GCA = CA (in months) −1. Using this algorithm, 9 infants were excluded from analyses using the GCA groups because their GCA was 1 month or younger and fell below the age limit for the youngest group, and 1.4% of the sample (64 of 4431) was reclassified into a contiguous younger age group.…”

“…veloped to evaluate infants born both LBW and preterm. 11,19 Unlike SGA infants born at term, preterm LBW infants show limited or no catch-up at least through the first 12 months, although those born AGA and preterm do relatively better. 12,31,32 This is unlike most of the findings on SGA infants, especially those born at term, for whom catch-up can be expected.…”

“…The early growth of infants born at the extremes of birth weight may be best evaluated by considering their birth status. 11,12 The Third National Health and Nutrition Examination Survey (NHANES III, 1988-1994, 13 a nationally representative, cross-sectional health examination survey, anthropometrically measured a sample of infants and children from the United States 2 months of age and older. This study produced the largest national data set available on infant and child size for subjects between the ages of 2 and 47 months.…”

“…45,46 When these charts become available for general clinical use, there will be opportunity to evaluate growth status based on an infant's weight at birth and, we would suggest, gestation. Although infants born preterm and small (LBW) may be best evaluated using charts specific to such children, 11,19 moderately LBW (1500-to 2500-g) infants born at term can be evaluated using the NCHS/CDC charts, recognizing that since they are also likely to be SGA, they may show catch-up but track at the lower percentiles through early childhood. However, of equal import, SGA status is associated with later growth despite the fact that 64% of the infants classified as SGA in this sample were not LBW, and only 10% were born preterm.…”

Monte Carlo simulations based on our population pharmacokinetic model suggest that vancomycin dosing guidelines based on serum creatinine concentration have a greater likelihood of achieving trough concentrations in the 5-15-mg/L range compared with other evaluated dosing regimens. None of the four dosing regimens is suitable to produce target trough concentration of 15-20 mg/L in an acceptable number of patients.
