식행동과 신체발달, 인지능력 및 과잉행동간의 관련성에 관한 연구 -제2보: 취학전 아동의 식행동과 각 변인간의 관련성에 대한 보고-

The purpose of this study was to examine the relationships of nutritional and social factors among 100 children aged $5{\sim}6$ years. Forty five children (45%) were selected from families with low socioeconomic status, while 55 children (55%) were from those with high socioeconomic status. Cognitive performance of the children was measured by the Draw a man test and the degrees of hyperactivity were assessed by both children's mothers and their teachers using two different Check List (Behavior check list and Conner's rating scale). There were few associations between cognitive performance and nutritional variables. However, levels of hyperactivity were related positively to diversity of food intake and weight percentage for age, and negatively to animal and processed food preferences. These results indicate a possible role of nutrition on psychological development.
