Authors proposed and examined a method for screening of children deemed to require nutritional guidance in the health examination of the three-year-olds. 1) Questionnaire A was prepared to classify the problems faced by children in their dietary life into five categories, and Questionnaire B was prepared for understanding the nature of these problems. 2) Questions of A were asked of 306 children, and they were classified into 5 groups; 5% (group A), 20% (group B), 39% (group C), 4% (group D), and 33% (group E). 3) Both groups A and B were found to follow irregular dietary patterns while group C was found to lack in interests toward diet. Therefore, they could be given group guidance based on these problems. 4) Group D had the most serious problem and required individual guidance. 5) Group E showed no particular problems. 6) It is concluded that practitioners in nutrition could rely on these questionnaires for rousing the interest of mothers in the dietary practices of their children.
