Head circumference percentile adults

Head circumference reflects brain size and is routinely measured up to 36 months. At birth, the brain is 25% of adult size, and head circumference averages 35 cm. Head circumference increases an average 1 cm/month during the first year; growth is more rapid in the first 8 months, and by 12 months, the brain has completed half its postnatal ....

The measurement of head circumference (also called occipitofrontal circumference [OFC]) is a direct reflection of head growth and an important step in the evaluation of childhood growth and development. The etiology and evaluation of macrocephaly in infants and children will be discussed here.Microcephaly is a Head Circumference greater than two standard deviations below the mean. Macrocephaly is a Head Circumference greater than two standard deviations above the mean. At the extremes (>97th percentile or <3rd percentile), small differences in percentiles represent clinically important differences in head circumference.

It does not seem biologically plausible to say there is more variability in the true measure of head circumference at 24 weeks compared with 34 weeks; the difference between the 3rd and 97th percentile is 7.4 cm vs. 5.7 cm, respectively. At 24 weeks in Figure 4C, the 3rd percentile is identical to the 10th percentile.Head size is a measure of the distance around the top of the child's head (circumference). Using standardized growth charts, health care providers compare the measurement with other children's measurements in percentiles. Some children just have small heads, with a measurement that falls below an established value for children of …Head Circumference. Head circumference is routinely measured during the first 2 years of life. During this time, the brain is growing rapidly and the open sutures between the bones of the skull are closing.
