What is the normal growth curve?
Normal growth is the progression of changes in height, weight, and head circumference that are compatible with established standards for a given population. The progression of growth is interpreted within the context of the genetic potential for a particular child [1].
Why was weight data for children greater than 6 years WHO participated in Nhanes III not included?
Why were the weights of children 6 years of age and older from NHANES III excluded from the growth reference used to develop the CDC Growth Charts? Measurement errors in NHANES III make the data invalid. The smaller sample size of older children in NHANES III made the curves statistically unreliable.
What does CDC percentile mean?
that indicate the rank of the child’s measurement. For example, when the dot is plotted on the 95th percentile line on the CDC BMI-for-age growth chart, it means that 5 of 100 children (5%) of the same age and sex in the reference population have a higher BMI-for-age.
Do children stay on the same growth curve?
We found that they go all over the place. From birth to 12 months, about two-thirds of the children fell by at least one percentile line with respect to weight (meaning they went from the 10th to fifth percentile, for example, or the 90th to 75th). More than one-third dropped by at least two lines.
How many inches a year does a boy grow?
around 3 inches
Boys go through a growth spurt during puberty. However, the rates of growth can vary a lot because boys go through puberty at different ages. On average, boys tend to grow around 3 inches (or 7.6 centimeters) per year during this period.
What is the average height of a 7 year old boy?
Big kid weight and height averages

What are CDC growth charts based on?
Weight, stature, length and head circumference are commonly used to assess size and growth. When any of these measures are combined with age or length/stature the result is an anthropometric index (for example, weight-for-age). The CDC Growth Charts reflect five anthropometric indices that are gender specific.
Which ethnic group is most likely to experience childhood obesity?
Childhood obesity is also more common among certain populations. Obesity prevalence was 25.6% among Hispanic children, 24.2% among non-Hispanic Black children, 16.1% among non-Hispanic White children, and 8.7% among non-Hispanic Asian children.
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 is the difference between CDC and WHO growth charts?
Whereas the WHO charts are growth standards, describing the growth of healthy children in optimal conditions, the CDC charts are a growth reference, describing how certain children grew in a particular place and time.
Do boys grow after 15?
Boys tend to show the first physical changes of puberty between the ages of 10 and 16. They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop.
