To determine the relationship of nutrient intakes with physical development of the blind school children, comparative studies were made on the diets served by boarding house of four blind schools in the Tohoku district (Miyagi, Yamagata, Akita and Iwate prefectures). From the nutrient intakes, the boarding houses were classified into two groups of A and B, the former being lower than the latter.
The results obtained are:
(1) The diets are limited and generally not well planned nutritionally, particularly the amounts of animal protein, fat, calcium, and vitamins were markedly low for growing children.
(2) In general, since the food cost per child per month is less than that of the average family, good nutrient intake of the blind school children is difficult.
(3) The children of A group compared with B group showed a higher percentage of symptoms usually accepted as associated with nutritional deficiency, for example the disappearance of knee-jerk.
(4) The differences in physical development of the blind school children of A and B groups between the ages of six to 20 years when compared as to height and weight were significant, A being distinctly inferior to B.
