The standard deviation (SD) represents the Z score. The thin lines represent the standard growth curves for girls based on data from the 2000 Annual Report of Child/adolescent growth charts show considerable BMI variations based on sex and of standard deviations from the mean—from CDC's 2000 growth charts. toring growth and to assess changes in the magnitude of malnutrition over time. However, W/A age (or height), divided by the standard deviation of the reference population. b. Percent of median: relation to BMI-for-age reference charts. The incidence of However, in EPI-INFO it is also possible to use a 2000 CDC ref-. terms of percentile and Z score (or Standard Deviation). There are two types of growth charts: growth standards and growth references. procedures, CDC revised the NCHS growth reference in 2000 for all children in the U.S population,. Similar to the CDC growth charts, these charts describe weight for age, length (or growth, use of the 2.3rd and 97.7th percentiles (or ±2 standard deviations)

## Generates a longitudinal growth chart, calculating percentiles and weekly weight change required to maintain percentile. WHO Growth Standard for 0 to 24 months Uses the 2006 WHO growth standard charts to report percentiles and Z-scores on infants from 0 to 24 months of age. CDC Growth calculator for 0 to 36 months

Standard deviation is a number that tells how far the data are from the average (mean). If the standard deviation of a distribution curve is large, then the data, in general, are far from the average; if the standard deviation is small, then the data are close to the average. CDC growth charts and the LMS method The CDC growth charts contain 10 smoothed percentiles (between the 3 rd and 97 th ) of BMI for 24 to 240 month-old children and adolescents [3]. CDC Growth calculator for 2 to 20 years. 2000 CDC growth charts to report growth metric percentiles and Z-scores on children and adolescents from 2 to 20 years of age. Includes Weight-for-age, Stature-for-age, Weight-for-stature, and BMI-for-age Support PediTools. Instructions. This web page allows you to calculate the body mass index (BMI) of your patients between the ages of 2 and 20 years, as well as the exact BMI percentile and z-score (standard deviation), based on the Center for Disease Control (CDC) growth charts. Z-scores are particularly useful to monitor changes in patients with a BMI above the 99th percentile or below the 1st percentile. Generates a longitudinal growth chart, calculating percentiles and weekly weight change required to maintain percentile. WHO Growth Standard for 0 to 24 months Uses the 2006 WHO growth standard charts to report percentiles and Z-scores on infants from 0 to 24 months of age. CDC Growth calculator for 0 to 36 months The z score is the standard deviation (SD) above or below the mean. A z score of 0 is the same as a 50th percentile, ± 1.0 plots at the 15th or 85th percentiles, respectively, ± 2 at roughly the 3rd or 97th percentiles. Uses CDC growth charts for babies (0-3 years).

### When comparing both growth charts, Canadian children had significantly different Mean and standard deviation were reported for normally distributed data,

Outcome measures: were converted to standard deviation scores (SDS) using the revised British format. These centile charts represent the average population of children from certain areas along with standard deviations. CDC (centre for disease control),. The World Health Organization (WHO) recommends cutoff values of +2 standard deviations, which correspond to the 2.3rd and 97.7th percentiles, to define abnormal growth. 1. For the WHO growth charts modified by CDC, these cutoff values are labeled as the 2nd percentile and the 98th percentile.

Standard deviation 3.3 Z score = 5.7/3.3 = +1.73 . Comparison of growth charts NCHS or WHO charts • Growth charts are established on large populations of normal children living under near-optimal conditions and therefore representing the range of normal growth for children at different ages. with CDC growth curves . From : WHO 2006 EN head circumference-for-age charts and tables. Year of the Nurse and the Midwife 2020 Understanding and using z-scores to track children’s growth. by Ellyn Satter, Family Therapist and Registered Dietitian. Children who are very large or very small can’t be accurately tracked on the standard growth charts. To understand and assess their growth, their weight needs to be converted to z-scores. Growth Chart Design. The automated growth charts were developed to use reference parameters and Z-score values for weight, height, and head circumference, such as those published by NCHS on the CDC Web site. 20 Based on the patient's age, the EHR system displays the appropriate reference growth chart (i.e., charts for 0–36 months for patients in that age range, and 2–20 years for patients

## The CDC has not evaluated the use of the WHO growth charts in premature or very low-birth weight infants. The 2000 CDC growth charts for the United States include data on low birth weight infants but do not include data on very low birth weight infants (VLBW; less than 1,500 grams). Alternate charts are available to assess the growth of VLBW infants.
