MOTILITY IN YOUNG INFANTS: II. RELATION TO TWO INDEXES OF NUTRITIONAL STATUS

PROBLEM  In previous reports¹ the relation of motility in new-born infants to the waking condition and to hunger were considered. The present problem is concerned with the relation of the amount of motility in sixty-six young infants to their nutritional status. The specific question to be considered is: Does the nutritional status affect motility in young infants?

METHOD AND APPARATUS  The apparatus and the methods of measuring motility have been described in another connection.^1b The nutritional status of the infants was determined according to two methods, one reported by Pirquet² and the second by Finlay.³ Pirquet has evolved a formula for the nutritional status of children. It is:He holds that the index is applicable to children of all ages. Subjects with a nutritional index ranging from 95 to 100 are considered normal; those above 100 are overfed, while those below 95 are considered undernourished.Finlay's³ tables were
