For K-12 students, obesity has been linked to student educational achievements. The study objective was to determine whether academic performance in university students is correlated with BMI. Students from two consecutive academic years (Jan-May 2013 and Jan-May 2014) were given an optional class survey in May, as extra credit. Of the 452 students that completed the survey, 204 females and 75 males (N = 279; 73% female and 27% male) consented to participate in the study. The number of correct answers to problem-solving questions (PSQs) and the overall final grade for the class were compared to the calculated BMI using linear regression with a Pearson's R correlation and unpaired -tests. BMI was significantly negatively correlated with student's final grades ( = 0.001 Pearson's r = - 0.190) and PSQs were positively correlated with final grades ( < 0.001; Pearson's r = 0.357). Our findings show a correlation between healthy body weight and improved academic performance. Further, the data suggest that future research in the area of body weight, diet, and exercise and any correlations of these with academic performance in college students are warranted.
对于K-12阶段的学生而言，肥胖与学业成绩存在关联。本研究的目的是确定大学生的学业表现是否与体重指数（BMI）相关。在5月份，对连续两个学年（2013年1月至5月和2014年1月至5月）的学生进行了一次选修课程调查，作为额外学分。在完成调查的452名学生中，204名女生和75名男生（N = 279；73%为女生，27%为男生）同意参与研究。使用Pearson相关系数R的线性回归和非配对t检验，将解决问题类题目（PSQs）的正确答案数量和课程的总体最终成绩与计算得出的BMI进行比较。BMI与学生的最终成绩呈显著负相关（P = 0.001，Pearson相关系数r = -0.190），PSQs与最终成绩呈正相关（P < 0.001；Pearson相关系数r = 0.357）。我们的研究结果表明健康体重与学业成绩的提高之间存在关联。此外，数据表明有必要对大学生体重、饮食和运动领域以及这些因素与学业成绩之间的任何相关性展开进一步研究。
