大学生健康相关行为与学业成绩的关系研究

目的探讨大学生健康相关行为与学业成绩的关系。方法采取整群抽样的方法,抽取某综合性大学医学院177名本科生,采用自行设计的大学生健康行为调查表进行调查,并查阅其必修课的学习成绩。结果 Spearm an等级相关分析表明学生的学业成绩好与生源(0.370)、有午睡(0.431)、爱吃早餐(0.379)和制定时间计划(0.274,P均<0.001)有显著相关,而学生平时(r=-0.171,P<0.05)和周末晚上睡觉(r=-0.364,P<0.001)越晚、周末晨起(r=-0.362,P<0.001)越迟、嗜好吸烟(r=-0.194,P<0.05)及饮酒(r=-0.230,P<0.01),则学业成绩越差。多元线性回归分析表明,被引入的自变量即生源、周末晚上睡觉的时间、午睡、吃早餐和制定时间计划可解释学业成绩总变异的42.2%(R2=0.422,F=19.448,P<0.001)。结论学生的学业成绩与生源、平时和周末晚上睡觉的时间、周末晨起的时间、午睡、吃早餐、制定时间计划、吸烟及饮酒等有关联。

The Relationship between Health-related Behavior and Academic Performance of College Students

Objective To explore the relationship between health-related behavior and academic performance of college students.Methods A total of 177 college students by cluster sampling in medical college of a university were investigated with Health Behavior Inventory for College Students by self-designed,and their academic performance of mandatory subjects.Results There were significant correlations between the following variables and higher academic performance：the source of students（r=0.370,P0.001）,having noon sleep（r=0.431,P0.001）,eating breakfast（r=0.379,P0.001）,using a planner to organize time（r=0.274,P0.001）.The following variables were associated with lower academic performance：later weekday bedtimes（r=-0.171,P0.05）and later weekend bedtimes（r=-0.364,P0.001）,later weekend wake-up times（r=-0.362,P0.001）,more smoking（r=-0.194,P0.05）and more drinking（r=-0.230,P0.01）.Multiple linear regression analysis determined that the independent variables included the source of students,weekend bedtimes,noon sleep,eating breakfast and time management;those accounted for 42.2% of the total variance in academic performance（R2=0.422,F=19.448,P0.001）.Conclusion College students＇ academic performance has a significant correlation with some health-related behavior.The set of variables include the source of students,weekday and weekend bedtime,weekend wake-up time,noon sleep,eating breakfast,time management,smoking and drinking habits.
