居民对预包装食品正面警示型标识的认知

Evaluation of the front-of-package warning labels of prepackaged food in China based on focus group discussion

目的了解公众对已设计的4种中国预包装食品正面警示型标识的认知和偏好,评价和筛选适宜的警示型标识。方法于2022年在6个省(自治区、直辖市)纳入116名访谈对象,对前期已设计好的4种预包装食品正面警示型标识进行小组访谈,通过问卷比较访谈对象对不同警示型标识外观设计、有效性和可接受性的看法和感受。结果4种警示型标识的总评分差异无统计学意义。城市访谈对象对黑色盾牌的总评分高于其余3种标识(P<0.05),大学及以上学历访谈对象对黑色盾牌的总评分高于黄色六边形(P<0.05),16岁以下儿童的父母或主要照顾者对4种警示型标识的总评分高于非父母或主要照顾者(P<0.05)。与其他3种警示型标识相比,黑色盾牌标识最能吸引访谈对象的注意力、最能影响购买意愿、最能起到不健康警示作用;黄色六边形标识最不吸引访谈对象的注意力、最不会影响购买意愿、最不具有不健康警示作用。结论对于预包装食品正面标识,黑色盾牌警示型最有效。

OBJECTIVE To understand the public's perceptions and preferences on the designed front-of-package warning labels of prepackaged food,and to evaluate and identify the effective warning label.METHODS A total of 116 participants were recruited from six provinces(autonomous regions/municipalities)in China.Focus group discussions were conducted with four types of warning labels on prepackaged food.And the score of attitude on different warning labels were compared.RESULTS There was no difference in the total score of the four warning labels.Total score of black shield label was higher in citizen participants and college education level participants than in their respective counterparts(P<0.05).Parents or primary caregiver of children under 16 years old gave higher scores to each labels than their respective counterparts(P<0.05).The black shield label was most likely to attract the attention of the respondents,most likely to influence the decision on eating and drinking,and most likely to have an unhealthy warning effect.The yellow hexagonal label was least likely to attract the attention of the respondents,least likely to affect the decision to eat and drink food,and least likely to have an unhealthy warning effect.CONCLUSION Black shield warning label is the most effective.
