There are several new features of the growth charts. These include
- The addition of the BMI-for-age chart for children and adolescents 2
to 20 years;
- The addition of the 85th percentile to identify at risk of
overweight on the BMI-for-age chart and weight-for-stature chart;
- The addition of the 3rd and 97th percentiles. Pediatric
endocrinologists and others providing services to special populations
may choose to use these charts when caring for children growing at the
outer percentiles;
- The limits for length and height were extended: On the
weight-for-length chart for children from birth to 36 months old,
length was extended from 49 to 45 cm. On the optional
weight-for-stature chart, the extension from 90 to 77 cm allows almost
all 2-year-old children to be plotted on the chart;
- The agreement of smoothed percentile curves and z-scores;
- Correction in the disjunction that occurred between 24 and 36 months
of age when switching from length to stature using the 1977 NCHS
growth charts.
