Newborn weight percentile charts
Growth Charts - Clinical Growth Charts
The clinical growth charts reflect modifications in the format of the individual charts, whereby two individual charts appear on a single page, and data entry tables have been added. The clinical charts have the grids scaled to metric units (kg, cm), with English units (lb, in) as the secondary scale. Clinical charts are available for boys and for girls. The available clinical charts include the following:
Infants, birth to 36 months:
- Length-for-age and Weight-for-age
- Head circumference-for-age and Weight-for-length
Children and adolescents, 2 to 20 years
- Stature-for-age and Weight-for-age
- BMI-for-age
Preschoolers, 2 to 5 years
- Weight-for-stature
The clinical charts for infants and older children were published in two sets.
- Set 1 contains 10 charts (5 for boys and 5 for girls), with the 5th, 10th, 25th, 50th, 75th, 90th, and 95th smoothed percentile lines for all charts, and the 85th percentile for BMI-for-age and weight-for-stature.
- Set 2 contains 10 charts (5 for boys and 5 for girls), with the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th smoothed percentile lines for all charts, and the 85th percentile for BMI-for-age and weight-for-stature.
Set 1 has the outer limits of the curves at the 5th and 95th percentiles. These are the charts that most users in the United States will find useful for the majority of routine clinical assessments. Set 2 has the outer limits of the curves at the 3rd and 97th percentiles for selected applications. Pediatric endocrinologists and others who assess the growth of children with special health care requirements may wish to use the format in set 2 for selected applications.
Two summary files, each with all 10 clinical charts in set 1 or set 2 are also available. These summary files contain the clinical charts from either set 1 or set 2 as described above.
Infants (birth to 24 months) must be measured for length, and the sex appropriate length-for-age or weight-for-length charts for infants, birth to 36 months must be used to plot the measurements.
At age 24 months and older, if children can stand unassisted and follow directions, stature should be measured and plotted on the stature-for-age chart for children (2 to 20 years). Otherwise, between 24 and 36 months, length can be used in place of stature.
BMI-for-age charts are recommended to assess weight in relation to stature for children ages 2 to 20 years. The weight-for-stature charts are available as an alternative to accommodate children ages 2-5 years who are not evaluated beyond the preschool years. However, all health care providers should consider using the BMI-for-age charts to be consistent with current recommendations.
All individual 2000 CDC growth charts have an initial publication date of May 30, 2000. For various reasons, modifications were made to charts after the initial publication date. For example, the individual charts were modified to create the clinical charts, which were made available on October 16, 2000. Subsequent modifications were made to selected clinical charts to correct or enhance particular aspects of the scales on the graphs.
In all cases, the data points in the corresponding data file for each modified chart remain unchanged from the initial release on May 30, 2000. Where applicable, when selected clinical charts were further modified, the date is indicated on each chart. The clinical growth charts for stature-for-age were modified because the scale for inches was not correctly aligned with the metric scale. The clinical growth charts for infant length-for-age and infant weight-for-age were revised to improve the appearance of the scale for inches on the length charts by extending the indicators at ½ inch increments, and enhancing alignment of the English with the metric scales on both the length and weight scales.
Users should use the most recent version of each chart, as available on the growth charts web site.
To view, print, and reproduce clinical growth charts
All clinical growth charts may be viewed, downloaded, and printed in Adobe Acrobat. For routine viewing on a computer monitor and printing on a laser printer, the individual charts are available as PDF files (Black and White).
All clinical charts have been colorized for viewing and printing. When routed to a color printer, the clinical charts for boys will print in blue and the clinical charts for girls will print in red. Otherwise, these same charts can be routed to a black-and-white printer, and will print in black-and-white. Higher resolution PDF files (Color) are available to provide the highest resolution and are intended to be used as a high quality print master for quantity production when using the services of a commercial printing facility. The recommended ink colors for printing are Pantone 206 red (for girls) and Pantone 286 blue (for boys). The recommended paper weight is 80#. Charts should be printed as two-sided copies, in the following combinations for each sex:
Infants, birth to 36 months:
- Side 1: Length for age + Weight-for-age
- Side 2: Head circumference-for-age + Weight-for-length
Children and adolescents, 2 to 20 years:
- Side 1: Stature-for-age + Weight-for-length
- Side 2: BMI-for-age or
- Weight-for-stature (age 2 to 5 years only)

Growth Charts - Background
Introduction
The growth charts consist of a series of percentile curves that illustrate the distribution of selected body measurements in U.
S. children. Pediatric growth charts have been used by pediatricians, nurses, and parents to track the growth of infants, children, and adolescents in the United States since 1977. The 1977 growth charts were developed by the National Center for Health Statistics (NCHS) as a clinical tool for health professionals to determine if the growth of a child is adequate. The 1977 charts were also adopted by the World Health Organization for international use.
When the 1977 NCHS growth charts were first developed, NCHS recommended that they be revised periodically as necessary. With more recent and comprehensive national data now available, along with improved statistical procedures, the 1977 growth charts were revised and updated to make them a more valuable clinical tool for health professionals. The 2000 CDC growth charts represent the revised version of the 1977 NCHS growth charts. Most of the data used to construct these charts come from the National Health and Nutrition Examination Survey (NHANES), which has periodically collected height and weight and other health information on the American population since the early 1960’s.
Growth charts are not intended to be used as a sole diagnostic instrument. Instead, growth charts are tools that contribute to forming an overall clinical impression for the child being measured. The revised growth charts provide an improved tool for evaluating the growth of children in clinical and research settings.
The 2000 CDC Growth Charts and the New BMI-For-Age Charts
The revised growth charts consist of 16 charts (8 for boys and 8 for girls). These charts represent revisions to the 14 previous charts, as well as the introduction of two new body mass index-for-age (BMI-for-age) charts for boys and for girls, ages 2 to 20 years.
Most of the specific differences between the revised charts and the original charts occur in the charts for infants, where national data were previously lacking. The revised head circumference charts also show some noticeable differences when compared to the earlier charts. Compared to the original infant charts that were based on primarily formula-fed infants, the revised growth charts for infants contain a better mix of both breast- and formula-fed infants in the U.
S. population. (On average, since 1970 approximately one-half of children born in the United States are reported to have been breast fed at some point, and about one-third have been breast fed for 3 months or more.) The addition of the BMI charts is probably the single most significant new feature of the revised growth charts.
These BMI-for-age charts were created for use in place of the 1977 weight-for-stature charts. BMI (wt/ht2) is calculated from weight and height measurements and is used to judge whether an individual’s weight is appropriate for their height. BMI is the most commonly used approach to determine if adults are overweight or obese and is also the recommended measure to determine if children are overweight. The new BMI growth charts can be used clinically beginning at 2 years of age, when an accurate stature can be obtained.
In recent years, BMI has received increased attention for pediatric use. In 1994, an expert committee charged with developing guidelines for overweight in adolescent preventive services (ages 11-21 years) recommended that BMI be used routinely to screen for overweight adolescents.
In addition, in 1997 an expert committee on the assessment and treatment of childhood obesity concluded that BMI should be used to screen for overweight children, ages 2 years and older, using the BMI curves from the revised growth charts. BMI can also be used to characterize underweight (though no expert guidelines exist for the classification of underweight based on BMI).
Methods and Development
For more information about the methods and development of the CDC Growth Charts, please see the 2000 CDC Growth Charts for the United States: Methods and Development [PDF – 5M] report.
Percentiles in infants and children, what are they for? How are they calculated?
As a child grows throughout their childhood, when they go to the pediatrician, they check growth charts to see if physical development is optimal for their age. Growth charts or percentiles help doctors and parents evaluate and monitor a child's growth. Although growth charts can provide important information, this information should not be the only diagnostic tool a clinician uses.
Percentiles are an analysis of information, but each child is different and does not always have to be accurate for everyone. nine0003

What are percentiles?
Percentiles are growth curves or charts that measure and compare children's height. regarding general and standard data. These parameters show height, weight and head circumference, which are considered normal at a certain age, taking into account, first of all, the first years of a baby's life. But it should be noted that every child is a world, and that the doctor himself will evaluate whether the boy or girl is really within the normal range or if there is something to be considered regarding their health.
nine0003
Growth curves contain a set of percentiles ranging from 5 to 95%. Doctors measure the circumference of the child's head, in children under 3 years old - weight and height. After collecting this data, the doctor plots the growth according to the child's age.
Weight, height and head circumference, if they fall within the graph, will indicate the percentile. This is adequate. Percentiles are a way to compare your child to other children. Higher percentages indicate a fatter or taller child, while lower percentages indicate a lighter or shorter child. nine0003
For example, a girl with the 75th weight percentile would be above 75 girls out of 100 and less than 25 girls out of 100. Percentiles also allow the clinician to compare height and weight to determine proportionate height. A child with a 90th percentile weight and 25th percentile height is likely to be too heavy for their height; whereas a child with the 50th percentile of height and weight has a good ratio.
Child Percentiles
If you want to know if your child's percentiles match their birth age, the first thing you need to do is Consult your pediatrician to determine suitable parameters. . The best percentile charts are the ones your pediatrician will have as they are likely to be based on the WHO charts. The percentile will display your child's weight or height on the growth chart (he may be above or below average), and you have nothing to worry about as they are standard values and everything is fine unless your pediatrician sees something unusual. ordinary, in which case they will have to tell you about it. nine0003
The growth of infants and children is influenced by many external factors, such as feeding or movement, but there is also a great deal of genetic influence. Even if your child or toddler is above or below the standard height, if they are happy, alert, active and in good health, they will rarely suffer from problems.
Percentile charts should only be a guide for you, but your pediatrician will always evaluate your child's growth, development, and health.
Percentile children
The same happens with infant percentiles in infant percentiles are indicative values and should not be of any concern. Although, if a child may be obese for his age, it would be wise for parents to take action in his life, not only because of what they invest in the percentile, but also for the good of his health.
Si the doctor appreciates that parents should take some action In particular, thanks to the data in the growth chart and the data that your child has regarding his weight, height and age, they will immediately inform the parents in order to find the best health solutions baby. nine0003
How to calculate percentile
Childhood obesity is a serious problem Millions of children in our society are overweight. Children under 6 years of age are overweight due to malnutrition and a sedentary lifestyle.
Obesity can cause developmental and health problems in children, and percentiles can be a great tool to determine if a child is on the path to becoming obese.
But in addition to physical health problems, there can also be emotional health problems that lead to low self-esteem in children when they feel that their body image is negative. nine0003
You can find calculators online to automatically calculate your children's percentile, but you can also do it yourself with or without the help of a doctor. To calculate the percentile, you must first calculate your BMI (body mass index), where will give you your ideal weight based on your current weight and height. You must remember that BMI does not calculate body fat, but only adequate weight based on height.
BMI is calculated by dividing weight by height in meters squared. nine0006 . For example, if your three-year-old son weighs 16'250 kg and is 92 cm tall, his BMI would be 19'19. The equation to get the BMI would be 16'250 / (0 x 92).
Knowing the BMI is not enough to know if a child is overweight, we must take into account the age and whether it is a boy or a girl.
After calculating the BMI, you should look at the growth chart of boys or girls according to the age presented by WHO, after which you can get the percentile corresponding to your son / daughter. Percentiles are an indicator that will help you recognize the relative position of your BMI in relation to your peer group. The average percentile will indicate normal weight, but the lower the risk of weight loss in a child and the higher the risk of being obese or overweight. nine0005 WHO classification of children:
- Percentile less than 5: underweight
- Percentile 5 to 85: normal weight.
- 85 to 95 percentile: overweight.
- Over 95 percentile: obesity
In BMI, the values would be:
- Less than 18: underweight.
- 18 to 24.9: Normal
- 25 to 26.9: overweight
- Over 27: obese
- From 27 to 29.
9: obesity I degree - From 30 to 39.9: obesity of the II degree.
- Over 40 years of age: III degree obesity

Body weight for age. BOYS
Birth to 5 years (percentiles)
In order to plot points on a graph, it is necessary to understand certain terms related to graphs and the rules for plotting points:
The x-axis is the horizontal coordinate axis at the bottom of the graph, which indicates the age of the child. It is necessary to put dots on the vertical lines corresponding to the full age of the baby.
Y-axis is the vertical axis of coordinates on the left side of the graph, on which body weight (kg) is indicated.
It is necessary to put points on the horizontal lines corresponding to the body weight with maximum accuracy. nine0120 Plotted point - a point on the graph at which the straight line coming from the corresponding measurement on the X-axis (age) and the straight line from the measurement on the Y-axis (body weight, kg) intersect.
| Percentile | < 3 | 3-15 | 15-85 nine0149 | 85-97 | >97 |
| Assessment of physical development | very low | below the average | average (norm) | above the average | nine0002 very high |
Let's analyze the example
The body weight of a girl at the age of 6 months is 5.
5 kg. Let's use the graph "Body weight for age": the point on the graph is below the red curve, which means that the child has insufficient body weight and it is urgent to seek advice from a pediatrician.

The x-axis is the horizontal coordinate axis at the bottom of the graph, which indicates the age of the child. It is necessary to put dots on the vertical lines corresponding to the full age of the baby.
Y-axis is the vertical axis of coordinates on the left side of the graph, which indicates body length/height (cm). It is necessary to plot points on horizontal lines corresponding to body length/height with maximum accuracy. nine0120 Plotted point - the point on the graph where the straight line from the corresponding measurement on the X-axis (age) and the straight line from the measurement on the Y-axis (length/height, cm) intersect.

| Assessment of physical development | very low | below the average | average (norm) | above the average | very high |
Let's take an example
The height of a boy at the age of 2 years is 88 cm. Let's use the graph "Body length / height for age": the point on the graph is located at the level of the 50th percentile, respectively, the height of the child is within the average values for his age.
