【摘要】：目的了解合肥市在校大学生对转基因食品的认知、态度和购买行为及其影响因素,为大学生科学认知转基因食品提供依据。方法自行设计调查问卷,通过随机分层整群抽取合肥市4所高校1 624名大学生进行调查,平均年龄为(22.5±2.2)岁。采用二分类非条件Logistic回归分析进行因素分析。结果在校学生转基因技术认知平均得分为6.1分,但缺乏系统性。转基因食品相关知识信息来源主要为互联网(76.05%)、电视(55.67%)和报刊杂志(35.47%),专业书籍较少(24.82%)。支持转基因食品者仅为16.87%,其中不同年龄、户籍所在地、家庭经济收入对转基因食品的认知水平差异有统计学意义(χ2值分别为19.885,22.371,20.338,P值均0.05);84.98%的大学生认为转基因食品需要醒目标示。不同年龄、家庭经济收入水平、接受度大学生购买行为构成的差异有统计学意义(P值均0.05)。大学生转基因食品知识获得渠道专业性不强,转基因食品购买行为与家庭经济收入水平成负相关;安全性、营养价值和价格是影响购买的主要因素(68.66%,47.78%,45.26%)。结论在转基因食品信息不对称的现况下,建议以强化客观公正的科普宣传、提高认知教育的专业性、借助新潮手段增强有效性、培养强制标示识别能力和阅读标签标识习惯为路径,做好相应的健康教育。
[Abstract]:Objective to investigate the cognition, attitude, purchase behavior and influencing factors of genetically modified food among college students in Hefei. Methods A self-designed questionnaire was designed, and 1624 college students from 4 universities in Hefei were selected by random stratified cluster. The average age was (22.5 卤2.2) years old. Two-classification non-conditional Logistic regression analysis was used to analyze the factors. Results the average score of cognition of transgenic technology was 6.1, but lack of systematicness. The main sources of GMF-related knowledge were Internet (76.05%), TV (55.67%), newspapers and magazines (35.47%), and few professional books (24.82%). There were significant differences in the cognitive level of genetically modified food between different age, household registration area and household income (蠂 ~ 2 = 19.88522.371or 20.338p, respectively). 84.98% of the college students thought that genetically modified food should be marked prominently. There were significant differences in the composition of purchase behavior among different age, family income level and acceptance degree (P < 0.05). College students' knowledge about genetically modified food is not professional, and the purchasing behavior of genetically modified food is negatively related to the level of family income. Safety, nutritional value and price were the main factors affecting purchase (68.66%, 47.78%, 45.26%). Conclusion under the condition of asymmetric information of genetically modified food, it is suggested to strengthen the objective and fair popularization of science, to improve the specialty of cognitive education, and to enhance the effectiveness by means of modern means. Develop the ability of mandatory marking identification and reading label marking habit as the path, and do a good job of health education.
