Knowing the level of consumers' nutritional knowledge is useful for promoting dietary habits. The aim of this study was to assess women's nutritional knowledge and their food label perception and their correlates. Three hundred and eighty Women referring to four large supermarkets in Shiraz were selected for this study. Data were collected through face-to-face interview. The NKQ questionnaire was used for designing the study questionnaire. The first part contained demographic characteristics and the second section encompassed questions related to nutritional knowledge of consumers about food components. The third part consisted of questions about labeling. Data were analyzed using SPSS 16. ANOVA and t-test were used for analyzing multi-variant variables. Chi-square test was used for evaluating the relationship between variables. 49.7% of the participants were healthy and others had chronic diseases. The mean score of the women's nutrition knowledge was 20.13 (from 24) and the average knowledge of women about food components were near 50%. Consumers' information about food labels application was less than 50% for all situations. The lowest use of labels was about low-salt labels and the highest for calorie content of foods. There was a significant relationship between educational status and food label use and also a significant relationship between information about added sugar and using low-sugar labels and between knowledge about low-salt foods and using low-salt labels. A significant relationship was also seen between knowledge about fat and cholesterol use for low fat foods. So, label application was correlated with educational level and nutritional knowledge of women.
了解消费者的营养知识水平有助于促进饮食习惯。本研究的目的是评估女性的营养知识、她们对食品标签的认知及其相关因素。本研究选取了设拉子四家大型超市的380名女性。通过面对面访谈收集数据。NKQ问卷用于设计研究问卷。第一部分包含人口统计学特征，第二部分涵盖与消费者对食物成分的营养知识相关的问题。第三部分由关于标签的问题组成。使用SPSS 16对数据进行分析。方差分析和t检验用于分析多变量变量。卡方检验用于评估变量之间的关系。49.7%的参与者健康，其他人患有慢性病。女性营养知识的平均得分是20.13（满分24分），女性对食物成分的平均认知接近50%。在所有情况下，消费者对食品标签应用的了解都不到50%。标签使用最少的是低盐标签，使用最多的是食品的卡路里含量。教育程度与食品标签使用之间存在显著关系，添加糖信息与使用低糖标签之间、低盐食品知识与使用低盐标签之间也存在显著关系。在脂肪知识与低脂食品的胆固醇使用之间也存在显著关系。因此，标签应用与女性的教育水平和营养知识相关。
