目的了解大连市高校学生外卖的使用情况及对外卖安全性的认知,提高大学生对外卖塑料包装可能造成的健康危害和环境污染的认识。方法采用分层抽样的方法,于2017年11月对大连市4所高校共800名学生进行使用外卖和对外卖安全性的认知调查,采用SPSS20.0软件分析数据。结果有效调查766人,其中77.0%的大学生有订外卖的习惯,男、女生订外卖的行为差异无统计学意义(P>0.05)。不同学校学生订外卖的行为差异有统计学意义(P<0.05),医科院校为84.1%,师范院校为80.6%,财经院校为78.4%,理工院校为65.8%。86.0%的大学生对外卖包装的安全性认知得分低于2分,男生得分(x=1.51)分高于女生(x=1.34)分,差异有统计学意义(P<0.05);不同学校大学生对外卖包装的安全性认知差异有统计学意义(P<0.05),师范院校学生得分最高(x=1.58)分,理工院校得分最低(x=1.22)分。95.0%的学生认为有必要了解外卖塑料包装相关知识,82.0%的学生愿意减少塑料包装制品的使用。结论目前大学生订外卖现象普遍,对外卖包装安全性的认知不足,需要加强外卖包装餐盒的安全性宣传和使用管理。

Objective To examine the consumption of take-out food and the cognition on packaging safety of take-out food among university students in Dalian city for improving knowledge on potential health risk and environmental pollution caused by plastic packaging of take-out food.Methods We conducted a self-administered anonymous questionnaire survey among 800 students selected in 4 universities in Dalian city using stratified cluster sampling in November 2017. SPSS 20.0 was used to process and analyze the data collected.Results Of 766 students with eligible responses, 77.0% reported the consumption of take-out food. There was no significant gender difference in reported rate of take-out food consumption (P > 0.05);but the reported rate differed significantly among the students in different universities (P < 0.05), with the rate of 84.1%, 80.6%, 78.4%, and 65.8% among the students in medical, normal, financial, and science and engineering university (P < 0.05). Among the students, 86.0% were graded a score of less than 2 for a total scale of 8 for knowledge on packaging safety of take-out food;the boy students had a significantly higher mean score than the girl students (x: 1.51 vs. 1.34, P < 0.05) and the mean knowledge score differed significantly among the students in different universities (P < 0.05), with the highest mean score of 1.58 and the lowest of 1.22 among the students in normal university and in science and engineering university. Of all the students, 95.0% reported the willingness to acquire knowledge about plastic packaging of take-out food and 82.0% expressed they would reduce the usage of disposable plastic packaging.Conclusion The consumption of take-out food is prevalent but the cognition on packaging safety of take-out food is poor among university students in Dalian city, suggesting that health education on this issue needs to be conducted in the students.
