It was found that 50% of the children in two villages in NE. Thailand were probably deficient in riboflavin. In contrast of 72 children examined in a Bangkok orphanage, only two gave results that indicated ariboflavinosis. Amongst rural children the test indicated that riboflavin deficiency was more common in those children over the age of two years. © 1970 Springer-Verlag.Mahidol UniversityChemistryArticleSCOPUS10.1007/BF01225731
