The purpose of this study was to examine whether the frequency of breakfast consumption was related to academic performance in healthy Korean adolescents.
We analyzed data from the seventh Korea Youth Risk Behavior Web-based Survey conducted in 2011, in which 75,643 adolescents from school grades 7-12 participated. We assessed the association between the frequency of breakfast consumption (per week) and academic performance using multivariate logistic regression analysis after adjusting for covariates such as age, body mass index, frequency of smoking, frequency of drinking, parents' education level, family economic status, frequency of vigorous physical activity (PA), frequency of moderate PA, frequency of muscular strength exercises, and level of mental stress.
For male adolescents, the odds ratios (ORs) for achieving average or higher academic performance according to the breakfast frequency per week were once per week, 1.004 (P=0.945); twice per week, 0.915 (P=0.153); 3 days per week, 0.928 (P=0.237); 4 days per week, 1.087 (P=0.176); 5 days per week, 1.258 (P<0.001); 6 days per week, 1.473 (P<0.001); and every day, 1.700 (P<0.001), compared to no breakfast per week. For female adolescents, the ORs for achieving average or higher academic performance according to the breakfast frequency were once per week, 1.068 (P=0.320); twice per week, 1.140 (P=0.031); 3 days per week, 1.179 (P=0.004); 4 days per week, 1.339 (P<0.001); 5 days per week, 1.449 (P<0.001); 6 days per week, 1.768 (P<0.001); and every day, 1.922 (P<0.001), compared to no breakfast per week.
The frequency of breakfast consumption is positively correlated with academic performance in both male and female healthy adolescents in Korea.
本研究旨在探讨韩国健康青少年的早餐食用频率与学业成绩之间是否存在关联。
我们分析了2011年开展的第七届韩国青少年风险行为网络调查的数据，共有7至12年级的75643名青少年参与。在调整了年龄、体重指数、吸烟频率、饮酒频率、父母教育水平、家庭经济状况、剧烈体育活动（PA）频率、中等强度PA频率、肌肉力量锻炼频率和心理压力水平等协变量后，我们使用多因素逻辑回归分析评估了每周早餐食用频率与学业成绩之间的关联。
对于男性青少年，与每周不吃早餐相比，根据每周早餐频率达到平均或更高学业成绩的优势比（OR）分别为：每周一次，1.004（P = 0.945）；每周两次，0.915（P = 0.153）；每周三天，0.928（P = 0.237）；每周四天，1.087（P = 0.176）；每周五天，1.258（P < 0.001）；每周六天，1.473（P < 0.001）；每天，1.700（P < 0.001）。对于女性青少年，与每周不吃早餐相比，根据早餐频率达到平均或更高学业成绩的OR分别为：每周一次，1.068（P = 0.320）；每周两次，1.140（P = 0.031）；每周三天，1.179（P = 0.004）；每周四天，1.339（P < 0.001）；每周五天，1.449（P < 0.001）；每周六天，1.768（P < 0.001）；每天，1.922（P < 0.001）。
在韩国，健康青少年的早餐食用频率与学业成绩呈正相关，无论男性还是女性皆是如此。
