Physical and intellectual development in Philippine children fed five different dietary staples

VB Guzman, HA Guthrie and GM Guthrie

Assessments of dietary intake, intelligence, physical growth, and clinical signs of malnutrition were made on 600 children from five Philippine communities. Five boys and five girls each at ages 8,9, and 10 from poor and less poor families drawn from town and rural schools in each community were examined. Dietary staples were rice, fish, corn, coconuts, and sweet potatoes, respectively, at the five sites. Analyses of variance indicated marked differences among communities in nutrient intake based on 24-hr recall, in intellectual and anthropometric measures and in clinical signs of malnutrition. There were few significant F ratios for urban-rural residence, socioeconomic status, sec, or age. There were positive correlations of approximately 0.20 between intake of calories and carbohydrates and intelligence; between calories and carbohydrates and anthropometric measures; and between intelligence and anthropometric measures. Clinical signs in the eye and on the skin showed low correlations of about-0.20 with dietary intake of protein, fat, thiamin, and riboflavin but not with vitamin A. In all communities energy intake was low reflecting limited fat consumption. Where rice or corn was the staple, thiamin and riboflavin were also frequent deficiencies; with fish, ascorbic acid; with sweet potatoes and coconuts, calcium, riboflavin, and thiamin. A very high incidence of eye changes, suggestive of a vitamin A deficiency, was found even where vitamin A intake seemed adequate.
