What is a centile growth chart?
The lines on the growth chart are called centiles (or percentiles) and show the expected pattern of growth. The numbers refer to the percentage of babies at or lower than the line, for example, a baby whose weight is on the 50th centile means that 50% of babies the same age as her are the same weight or less.
Do Pediatricians use growth charts?
Growth charts consist of a series of percentile curves that illustrate the distribution of selected body measurements in 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.
How do you read a pediatric growth chart?
The percentile number means that your child exceeds that percentage of children their age for that measurement.
- If your child is in the 75th percentile for height, they are taller than 75% of other kids their age.
- If they are in the 25th percentile for weight, they only exceed 25% of children their age in weight.
What is UK90?
INFANCY. Only the GP (which incorporated the original Tanner and Whitehouse infancy reference) and the UK90 references cover the ages from birth to 2 years. The GP has not been updated since 1975, apart from the addition of earlier gestations.
Is 9th centile small?
Centile charts show the position of a measured parameter within a statistical distribution. If a parameter such as height is on the 9th centile, this means that for every 100 children of that age, 9 would be expected to be shorter and 91 taller. On the 25th centile, 25 would be shorter and 75 taller.
What centile is underweight?
underweight – on the 2nd centile or below. healthy weight – between the 2nd and 91st centiles. overweight – 91st centile or above. very overweight – 98th centile or above.
Do percentiles really matter?
A healthy child can fall anywhere on the chart. A lower or higher percentile doesn’t mean there is something wrong with your baby. Regardless of whether your child is in the 95th or 15th percentile, what matters is that she or he is growing at a consistent rate over time.
Are CDC growth charts accurate?
“Although the charts are commonly used to graphically illustrate the typical growth patterns for boys and girls, it is important to note that they do not accurately reflect the growth of all children,” she says.
What percentile should my baby be in?
What’s the Ideal Percentile for My Child? There is no one ideal number. Healthy children come in all shapes and sizes, and a baby who is in the 5th percentile can be just as healthy as a baby who is in the 95th percentile.
How do you read BMI by age?

What is the difference between the uk90 and the GP?
Only the GP (which incorporated the original Tanner and Whitehouse infancy reference) and the UK90 references cover the ages from birth to 2 years. The GP has not been updated since 1975, apart from the addition of earlier gestations. The UK90 reference is both more recent and based on larger numbers at all ages.
Is the uk90 a good reference for clinical research?
The group concluded that for most clinical purposes the UK90 reference is superior and for many measures is the only usable reference that can be recommended, while the original Tanner–Whitehouse and the Gairdner–Pearson charts are no longer reliable for use at any age.
Is the uk90 weight reference already out of date?
The UK90 weight reference fits contemporary data better, but it has been suggested that this is already out of date as a description of current norms, with a rapid trend to increasing weight, particularly in older children and at the top end of the age range. 13
What is the difference between Buckler height and uk90 height?
In puberty height normally crosses centiles, because of the variation in age at onset. This makes cross sectional references unhelpful for assessing growth in individual children. The Buckler reference incorporates Tanner’s allowance for variations in growth rate over puberty, while the UK90 reference does not.
