山西省消费者转基因食品认知现状及接受意愿分析

Cognition on and consumption intention of genetically modified food among consumers in Shanxi province

目的了解山西省消费者转基因食品认知现状、接受意愿及其信息获取渠道,为进一步有针对性地发展和应用转基因食品提供参考依据。方法2016年12月—2017年3月,采用多阶段分层随机抽样方法对山西省5个市区共计2500名消费者进行问卷调查。结果单因素分析结果显示,不同年龄(χ2=57.674,P<0.01)、文化程度(χ2=69.910,P<0.01)、婚姻状况(χ2=40.325,P<0.01)、职业类型(χ2=89.480,P<0.01)、家庭规模(χ2=6.316,P<0.05)和恩格尔系数(χ2=10.629,P<0.05)的消费者对转基因食品认知现状差异均有统计学意义。多因素分析结果表明文化程度、职业类型和恩格尔系数是影响消费者转基因食品认知的重要因素。转基因食品的安全性(χ2=48.706,P<0.01)、营养含量(χ2=48.706,P<0.01)、价格水平(χ2=71.894,P<0.01)是影响消费者接受意愿的重要因素。电视节目、手机、互联网是消费者获得转基因食品的主要途径。结论山西省消费者转基因食品基础知识及格率较低,尤其是低学历消费者,有关部门应加强转基因食品知识宣传,针对不同特征人群采取不同措施。

Objective To examine genetically modified food(GMF)-related cognition,intention of consumption,and information resource among consumers in Shanxi province fro providing references for production and consumption of GMF.Methods We recruited 2500 residents in 34 counties/districts of 5 municipalities in Shanxi province using stratified multistage random sampling and conducted a face-to-face questionnaire survey from December 2016 to March 2017.Results The response rate of the survey was 88.6%.Univariate analysis showed that respondents′cognition on GMF differed significantly by age(χ2=57.674,P<0.01),education(χ2=69.910,P<0.01),marital status(χ2=40.325,P<0.01),occupation(χ2=89.480,P<0.01),family size(χ2=6.316,P<0.05),and Engel′s coefficient(χ2=10.629,P<0.05).Multivariate analyses indicated that education,occupation and Engel′s coefficient were significant influencing factors for cognition on GMF of the respondents.The respondents′intention of GMF consumption was significantly impacted by perceptions on GMF′s safety(χ2=48.706,P<0.01),nutritional content(χ2=48.706,P<0.01)and price(χ2=71.894,P<0.01).Television programs,mobile phones and the internet were main ways for the respondents to obtain GMF-related knowledge.Conclusion The cognition on GMF is at a low level among consumers,especially among those with low education,in Shanxi province,suggesting that targeted education programs on GMF need to be promoted among the public.
