摘　　要：目的调查留守儿童经历对湖南某重点高校学生营养与食品安全知信行的影响。方法以班级为单位进行整群抽样,抽取该校12个班级的学生,用自行设计的问卷对其营养与食品安全知信行进行调查;而后一周内对所有接受调查学生进行干预,干预一个月后再进行第二次调查,采用卡方检验分析比较干预前后有无留守儿童经历的大学生营养与食品安全知信行认知情况。结果知识项目的知晓率,干预前两组学生无明显差异(P>0.05);干预后有留守儿童经历学生"促进钙吸收的维生素"知晓率为69.4%、"食品添加剂使用"为82.3%、"未煮透豆浆引起中毒"为74.2%,低于无留守儿童经历学生的三者知晓率(80.8%、91.6%及86.1%)(P<0.05)。干预前有留守儿童经历学生态度3分和4分率之和在"对路边摊食品态度"为42.2%、在"认为不口渴不用喝水"为87.5%、在"对食品安全现状态度"为45.3%,而无留守经历学生态度3分和4分率之和则分别占58.1%、96.8%、52.2%,优于有留守经历儿童学生(P<0.05);干预后两组学生无差异(P>0.05)。干预前两组学生行为差异无统计学意义(P>0.05);干预后无留守儿童经历的学生行为3分和4分率之和在"辨认食品保质期"占65.6%,优于有留守儿童经历的学生的46.8%(P<0.05)。结论留守儿童经历使大学生某些营养与食品安全知识和行为的干预效果差,而干预后态度转变明显。Objective To investigate the influence of childhood left-behind experience on college students’knowledge,attitude and practice(KAP)of nutrition and food safety in a key university in Hunan province.Methods A cluster sampling based on taking the class as a unit was conducted to select students from 12 classes of the university.A self-designed questionnaire was used to survey the students’KAP of nutrition and food safety,and then,a one-month intervention was performed among them in the following week.The second survey was conducted after the one-month intervention period.Chi-square test was used to analyze and compare the awareness of KAP of nutrition and food safety before and after the intervention between students with and without childhood left-behind experience.Results No statistically significant difference was found in the awareness rate of knowledge before the intervention between the groups with and without childhood left-behind experience(P>0.05).After the intervention,the awareness rates of knowledge about vitamins that promoted calcium absorption,use of food additives,and poisoning caused by unboiled soymilk in students with childhood left-behind experience were all lower than those of students without childhood left-behind experience(69.4%vs.80.8%,82.3%vs.91.6%,74.2%vs.86.1%,all P<0.05).Before the intervention,the rates of scoring 3 and more points in attitudes towards"the food of roadside stalls","no thirsty,no water",and"current status of food safety"in students with childhood left-behind experience were inferior to those in students without childhood left-behind experience(42.2%vs.58.1%,87.5%vs.96.8%45.3%vs.52.2%,all P<0.05),but no statistically significant differences were found after the intervention(all P>0.05).Before the intervention,a comparison of behaviors regarding nutrition and food safety of students with and without childhood left-behind experience showed no statistically significant differences(P>0.05).After the intervention,the rate of scoring 3 points and above in behavior regardin
