Understanding Weight Percentiles
To determine a healthy weight range for a 14-year-old, it's essential to understand weight percentiles. Weight percentiles are a measure of a child's weight in relation to their height and age. It's a way to compare a child's weight to that of other children of the same age and sex. The percentiles are calculated based on data from the Centers for Disease Control and Prevention (CDC) growth charts. For a 14-year-old, the CDC growth charts provide the following weight percentiles:- 5th percentile: 114.5 lbs (51.8 kg) for boys, 107.5 lbs (48.6 kg) for girls
- 50th percentile: 145.3 lbs (65.8 kg) for boys, 133.5 lbs (60.4 kg) for girls
- 95th percentile: 176.5 lbs (79.8 kg) for boys, 162.5 lbs (73.5 kg) for girls
