Document Summary
Measurement techniques: weight: the subject stands, lies, or sits in the center of a balance scale platform. Minimal clothing and no shoes should be worn. Weight is taken to the nearest 0. 1 kg or 1. 0 oz in children and to the nearest 0. 01 kg or 0. 5 oz. in infants: length/height: measurement of length is frequently erroneous because of improper technique or equipment. Shoulders should be straight and the subject should look straight ahead. Measurements should be to the nearest 0. 1 cm or 0. 125 in: head circumference: a flexible, narrow tape measure is placed firmly around the head above the supraorbital ridges and over the frontal bulge, where the circumference is greatest. The layer of skin and subcutaneous tissue is pulled away from the underlying muscle and held until measurement with the calipers at the midpoint has been taken. Readings should be taken to 0. 5 mm,3 s after application of calipers.
