摘要

⽬的 1.评估坤成中学学⽣BMI现状,找出需要重点关注和⼲预的群体。2.分析学⽣饮
⻝习惯对BMI的具体影响，明确应当改善的主要饮⻝问题。3.探讨学⽣运动习惯与BMI的

关系，为促进体育锻炼提供依据。⽅法 采⽤问卷调查的⽅式进⾏数据收集，邀请初⼆⾄⾼
⼆学⽣⾃愿参与填写。样本量为1163份，并运⽤统计分析软件 SPSS 进⾏数据处理和相关
性分析。结果 BMI正常指数学⽣占82.4%，低于正常指数占7.9%，⾼于正常指数占
9.7%。喜好摄⼊清淡、油炸、⾼盐、⾟辣⻝品和甜品的学⽣分别占31.9%、20.4%、

14.2%、14.3%和19.2%。55.3%学⽣每周只运动⼀⾄两次，38.3%学⽣⼀次运动时⻓少于
60分钟。进⼀步分析发现，⾼盐和⾼脂肪油炸⻝品的摄⼊量与学⽣BMI呈现显著正相关，
而运动参与情况与BMI之间未发现明显关联。这⼀结果提⽰,改善学⽣饮⻝结构或许是影响
BMI的关键所在，而适度运动虽未直接影响BMI，但仍有利于促进学⽣的整体健康⽔平。

结论 坤成中学学⽣在⾝体健康、饮⻝和运动习惯等⽅⾯所⾯临的主要问题及其相互影响，
为学校制定针对性的健康教育和⼲预措施提供了理论依据。未来还需进⼀步探讨BMI指标
的局限性，更多关注学⽣综合健康状况的评估和促进。

Abstract

Objective To study the body mass index (BMI), exercise and eating habits of Kuen Cheng
High School students to provide evidence for guiding the students to promote good physical
quality and healthy eating habits. Methods The data for this study was collected through a
questionnaire survey. Students from grade 7 to grade 11 were invited to participate

voluntarily. Of the valid questionnaires, the sample size was 1163. The data was input and
organised using Excel software and then analysed using SPSS software, including bivariate
correlation analysis and frequency analysis. Results The study shows that approximately

82.4% of students have normal BMI while 17.6% have abnormal BMI. The consumption of
light, fried, high sodium, spicy, and sweet food among students is 31.9%, 20.4%, 14.2%,
14.3% and 19.2%, respectively. 55.3% of students exercise 1 to 2 times a week and 38.3%
exercise 1-60 minutes per time. Conclusion The study revealed the major issues faced by
students at Kuen Cheng High School regarding physical health, dietary habits, and exercise

habits, as well as the interrelationships among these factors. It provided a theoretical basis
for the school to develop targeted health education and intervention measures. In the future,
it is necessary to explore the limitations of the BMI indicator further and pay more attention

to assessing and promoting students' overall health status.
