Overview

Height and weight chart

Alternative Names:

Growth chart
Information:

A growth chart is used to measure and compare a child's growth with what is considered normal for that child's age and gender. The nationally accepted growth charts are based on measurement data collected by the National Center for Health Statistics. The parametersmeasured include height, weight, and head circumference.

Height and weight measurements are used to document a child's height or length (in inches or centimeters), weight (in ounces and pounds, or grams and kilograms), based on his age in weeks, months, and years. For children under 3 years, height ismeasured while they are lying down. For children over 3,heightis measured whilestanding. Height and weight measurements are recorded and graphed until the child is17.

Head circumference is a measurement of the size of the head taken by wrapping a tape measure above the eyebrows and around to the back of head.

Measurements are compared to the standard (normal) range for children of the same gender and age. Results are read as percentiles of average. For example, a child with a height at the 75th percentile means that only about 25% of children the sameage and gender are taller and about 75% of children are shorter.

Growth charts are important in that they may provide an early warning that the child has a medical problem. For instance, during the first 18 months of life and particularly during early infancy, abnormal growth of the headcan alert the doctor to aproblem.

Growth that is too rapid may indicate the presence of hydrocephalus (water around the brain), a brain tumor, or other conditions that cause macrocephaly (abnormally large head). Growth that is too slow may indicate problems in brain development, early fusion of sutures (the bones of the skull), or other problems.

Insufficient gain in weight, height or a combination may indicate failure-to-thrive, chronic illness, neglect, or other problems.

Abnormal growth as seen on the growth charts is only an indicator of a potential problem. Your doctor will determine if it represents an actual medical problem or simply needs to be followed carefully. Because of individual variations in genetics and hormones, growth charts are not an accurate predictor of a child's future, full-grown height.
