目的了解我国4城市学生及教师对食品营养标签知晓及使用情况,为在学校推动国家食品营养标签健康教育行动的实施提供科学依据。方法采用分层随机整群抽样方法,在武汉市、成都市、沈阳市、广州市根据区域经济状况各随机选取3个区小学、初中及高中的11 120名学生、2 370名教师进行营养标签知晓和使用情况问卷调查。结果分别有86.54%(9 623人)的学生和80.34%(1 904人)的教师知道包装食品的外包装上有食品营养标签,仅有11.83%(1 316人)的学生和3.59%(85人)的教师全部答对必须标示的能量和核心营养素,其中知道含有钠的比例最低;仅有14.61%(1 625人)的学生和16.12%(382人)的教师在选购食物时会经常使用食品营养标签。不同性别、文化程度、承担工作、经济收入、学段间对食品营养标签的知晓使用情况比较差异有统计学意义。结论 4城市学生、教师知道食品营养标签的比例有所增高,但全部答对食品营养标签具体标示的能量、核心营养素和使用食品营养标签选购食物的比例低。需在学校加大食品营养标签的宣贯力度,并加强学校营养健康相关知识的教育。
Objective To understand the knowledge and use of food nutrition labels by students and teachers in 4 cities in China and provide a scientific basis for implementing the health education campaign of national food nutrition labeling in schools. Methods A stratified random cluster sampling method was used to randomly select 11 120 students and 2 370 teachers from 3 districts in Wuhan, Chengdu, Shenyang and Guangzhou according to the regional economic conditions to conduct nutrition labeling Awareness and Use Questionnaire. As a result, 86.54% (9 623) students and 80.34% (1 904) teachers knew that there was a food nutrition label on the outer packaging of packaged foods, only 11.83% (1316) students and 3.59% (85) People) answered all the energy and core nutrients that must be labeled, of which the lowest was found to contain sodium; only 14.61% (1,625) of the students and 16.12% (382) of the teachers used the food regularly Food nutrition label. There were significant differences in the use of food nutrition labels between different genders, educational level, job-taking and economic income. Conclusions In 4 cities, teachers and students know that the proportion of food nutrition labels has increased, but all those who answer the specific labeling of food nutrition labels have a low proportion of core nutrients and foods that use food nutrition labels. It is necessary to intensify the promotion of food nutrition labeling in schools and to strengthen education on nutrition and health related knowledge in schools.
