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 ( : 1.51 vs. 1.34, x¹ 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 takeout 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
【摘 要】 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 SPSS 20.0 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。
