南京市居民微量元素知晓程度的相关研究

Subject Investigation of understanding degree on microelement knowledge of Nanjing residents

目的:了解南京市居民微量元素知识知晓程度,为针对性地指导人们正确利用微量元素提供参考。方法:采用多阶段、分层和系统抽样相结合的方法确定调查对象,选择铁、碘、氟、锌、硒5种常见微量元素的主要作用、饮食来源以及相关疾病作为调查问卷内容开展现况调查。结果:微量元素总体知晓率较低,仅49.7%;50岁以上群体、低文化人群知晓程度明显低于其它人群;微量元素的知晓程度存在明显的不平衡性,硒元素相关知识知晓程度明显低于铁、碘、氟及锌4种元素。结论:居民对饮食平衡的道理均有一定程度的了解,但对具体微量元素知识却知之甚少,不同人群对不同微量元素的知晓程度差异较大,需针对性地开展营养教育,科学、准确地宣传微量元素知识。

Objective：To realize the understanding degree about microelement knowledge of Nanjing residents and provide reference to conduct targeted making use of microelement. Methods： Choosing the survey objects by the combined methods of multistage, stratified and systematic sampling. We design a survey questionnaire contained Fe, I, F, Zn, Se five kinds of the hackneyed microelements＇ central function,the dietary source and the diseases caused by them to carry ort the prevalence survey. Results： The collectivity understanding degree of microelement knowledge is low, which is only 49.7 % ; residents over the age of 50 years and the residents with less schooling have an obviously lower rate than the others; the understanding degree on microelements is obviously lopsided; the understanding degree of Se is markedly lower than Fe,I ,F and Zn four element. Conclusion： Most people have basic ideas on a balanced diet but not up to concrete microelements. The knowledge of different trace elements in various populations has a greater difference so pointed. We must adopt pertinent measures to carry out nutritional education, and publicize the knowledge of mieroelement by scientific and accurate way.
