HEGIRA ADAPTATION OF THE NCHS WEIGHT AND HEIGHT CHARTS

The ages of Saudi children are recorded and based on the Hegira calend ar. When charted on the National Center for Health Statistics (NCHS) w eight and height charts, children will be at a disadvantage since the Hegira year is shorter than the Gregorian year. In this paper, centile s for the NCHS reference population are estimated for age in Hegira ye ars from 2-18 for height and weight for both sexes using mathematical interpolation. Charts are prepared for use in hospitals and health cen ters for children whose ages have been reported based on the Hegira ca lendar.
