目的分析学生食用早餐频率与学习成绩的相关性,为学生营养改善相关政策的实施提供理论依据。方法从50个“农村义务教育学生营养改善计划”重点监测县,按照学校食堂供餐、企业(单位)供餐和家庭(个人)托餐3种供餐模式随机抽取2所小学和初中,抽取的学校每年级随机抽取1~2个班,共34 808名中小学生。通过学生问卷调查学生食用早餐频率,同时收集2011—2012学年学生下半学期语文、数学和英语期末考试成绩。结果建模分析显示,与食用早餐频率≥5次/周的学生相比,不吃早餐学生的语文、数学和英语平均成绩分别低(1.9±0.4),(1.8±0.5)和(1.9±0.5)分,差异均有统计学意义(t值分别为-4.9,-3.8和-3.7,P值均<0.05);食用早餐1~4次/周学生的语文、数学和英语平均成绩分别低(0.9±0.2),(1.0±0.3),(0.8±0.3)分,差异均有统计学意义(t值分别为4.3,-3.8和-2.6,P值均<0.01)。结论不吃早餐将会影响学生学习成绩,对女生及初中生的影响更大。
Objective To analyze the correlation between students’ eating breakfast frequency and academic performance, and to provide a theoretical basis for the implementation of policies related to nutrition improvement of students. Methods From 50 “rural compulsory education students nutrition improvement plan” focus on monitoring counties, in accordance with the school canteen feeding, business (unit) feeding and family (personal) meals three feeding patterns randomly selected two primary and junior high school , The school selected each grade randomly selected 1 to 2 classes, a total of 34 808 primary and secondary students. Through the student questionnaire students eat breakfast frequency, at the same time to collect 2011-2012 school year second semester Chinese, math and English final exam results. Results The results of modeling analysis showed that the average scores of Chinese, math and English students who did not eat breakfast were lower (1.9 ± 0.4), (1.8 ± 0.5) and (1.9 ± 0.5) respectively than those who consumed breakfast more than 5 times per week ), The differences were statistically significant (t = -4.9, -3.8 and -3.7 respectively, P <0.05). The average scores of Chinese, math and English for students who took breakfast 1 ~ 4 times a week were lower 0.9 ± 0.2), (1.0 ± 0.3) and (0.8 ± 0.3) points, respectively (all t = 4.3, -3.8 and -2.6, P <0.01). Conclusions Failure to eat breakfast will affect students’ academic performance, which will have a greater impact on girls and junior high school students.
