The purpose of this study was to obtain a fuller understanding of the association of dietary behaviours, physical status and socio-economic status with academic performance in Korean teenagers. The subjects in this study were 6,463 boys and girls, in grade 5, 8, and 11 in Korea. A self-administered questionnaire and the food-frequency form were used. Grade point average (GPA), height, weight, and physical fitness score for the year were recorded from the school record. The academic performance of students was strongly associated with dietary behaviours, especially with regularity of three meals even after control for parent's education level. Regular breakfast and lunch were more important in grades 5 and 8, while regular dinner was more related with academic performance in grade 11. Small, positive associations of height and physical fitness to academic performance were also found. The relative importance of regularity of meals was greater than that of socio-economic status and physical status in older teenagers. The results of this study suggest that accommodation of better dietary environment and nutrition education for three regular meals is recommended.
本研究的目的是更全面地了解韩国青少年的饮食行为、身体状况和社会经济状况与学业成绩之间的关联。本研究的对象是韩国5年级、8年级和11年级的6463名男女生。使用了一份自填式问卷和食物频率表。从学校记录中记录当年的平均绩点（GPA）、身高、体重和体能得分。即使在控制了父母的教育水平之后，学生的学业成绩仍与饮食行为密切相关，尤其是与三餐规律有关。规律的早餐和午餐在5年级和8年级更为重要，而规律的晚餐在11年级与学业成绩的关系更为密切。还发现身高和体能与学业成绩之间存在微小的正相关。在年龄较大的青少年中，三餐规律的相对重要性大于社会经济状况和身体状况。本研究结果表明，建议提供更好的饮食环境并开展三餐规律的营养教育。
