目的了解乙二胺四乙酸铁钠(NaFeEDTA)强化酱油在我国不同地区的可接受性和需求,以及人们对铁元素营养知识和铁缺乏的认识情况。方法采用自行设计的结构问卷在北京、河北、吉林、贵州4省市进行了571位居民的问卷调查,调查采用调查员指导下自填和由调查员访谈的形式进行。结果4个地区的居民对铁强化酱油了解均较少,知识总平均得分6.4(总分11,北京6.9、河北7.6、吉林6.4、贵州4.9)。居民对铁强化酱油报以犹豫怀疑的购买倾向,4个地区购买意向总平均分15.4(分值范围6~29,得分越低购买意向越强,北京16.6、河北15.1、吉林15.5、贵州14.5)。在铁缺乏认知、铁强化酱油接受程度、市场需求等方面存在显著的地区差异,北京最高,贵州最低。知识水平、消费观念、收入水平影响着铁强化酱油的推广。结论应该结合不同地区的实际情况因地制宜地开展铁强化酱油宣传推广和干预。
Objective To understand the acceptability and demand of NaFeEDTA fortified soy sauce in different regions of China and the knowledge of iron nutrition and iron deficiency. Methods A questionnaire survey was conducted among 571 residents in Beijing, Hebei, Jilin and Guizhou provinces using a self-designed structured questionnaire. The survey was conducted under the guidance of investigators and interviews with investigators. Results Residents in the four regions did not know much about iron fortified soy sauce. The average knowledge score was 6.4 (total score 11, Beijing 6.9, Hebei 7.6, Jilin 6.4, Guizhou 4.9). Residents tended to suspect the purchase of iron-fortified soy sauce. The average purchase intention in each of the four regions averaged 15.4 points (score range 6 to 29, with a lower score, the stronger the purchase intention, Beijing 16.6, Hebei 15.1, Jilin 15.5 and Guizhou 14.5) . There is a significant regional difference in iron deficiency awareness, acceptance of iron fortified soy sauce, and market demand, with the highest in Beijing and the lowest in Guizhou. Knowledge, consumer attitudes, income levels affect the promotion of iron-fortified soy sauce. Conclusions It is suggested that iron-fortified soy sauce should be popularized and interfered with according to local conditions according to the actual conditions in different regions.
