Children, like adults, differ in degrees of activity; that is, one child may be very active, running and playing more strenuously than another. Hence a margin of safety must be allowed to cover the energy expenditures of the more active child, to safeguard it against becoming malnourished. To facilitate the computation of the food requirements of children a schedule showing the number of calories per pound of body per day is included on opposite page. The food requirements are such as to allow of a steady increase in the weight and stature of the child; the rate of gain for normal children should be as follows: AVERAGE RATE OF GAIN PER WEEK, FOR NORMAL CHILDREN =======================+================== _Age_ | _Average_ _Boys_ | _gain,_ | _Ounces_ -----------------------+------------------ First year | 3-1/2 - 4-1/2 Second year | 2-1/2 - 3 Third year | 1-3/4 - 2 Fourth to eighth year | (inclusive) | 1-1/4 - 1-1/2 Ninth to eleventh | year (inclusive) | 1-3/4 - 2 Twelfth to thirteenth | year (inclusive) | 2-3/4 - 3 Fourteenth to | sixteenth year | (inclusive) | 3 - 4 =======================+================== =======================+================== _Age_ | _Average_ _Girls_ | _gain,_ | _Ounces_ -----------------------+------------------ First year | 3-1/2 - 4-1/2 Second year | 2-1/2 - 3 Third year | 1-3/4 - 2 Fourth to eighth year | (inclusive) | 1-1/4 - 1-1/2 Ninth to twelfth | year (inclusive) | 1-3/4 - 2-1/4 Thirteenth to | fifteenth year | (inclusive) | 2-3/4 - 3-1/4 Sixteenth and | seventeenth year | (inclusive) | 1 - 2 =======================+==================
