The prevalence of non-communicable diseases (NCDs) is increasing in the world. Healthy food choice and adequate physical activity are key factors in preventing NCDs. Food labeling is a strategy that can inform consumers to choose healthier foods at the point of purchase. In this study, we intend to examine the status of existing labels and to clarify their strengths and weaknesses. Then, for the first time in Iran, we will design a type of physical activity equivalent calorie label and will test it on some food groups of packaged products including dairy products, sweetened beverages, cakes, and biscuits.
This study will be conducted in two phases. In phase 1, nutrition fact labels and traffic light labels will be assessed through focus group discussions and interviews among different groups of mothers, industrialists and nutrition and food industry specialists as to determine strengths and weaknesses of the current labels on packaged products. Then, the initial layout of the physical activity calorie equivalent label will be drawn with respect to the viewpoints received from mothers. Thereafter, we will include the scientific opinions to it for creating the first draft of our new label. In phase 2, a total of 500 mothers of students 6-12 years old randomly assigned to five groups. The study groups will be as follows: (1) without nutrition label group, (2) current traffic light label group, (3) current traffic light label group in which, a brochure will be used to inform mothers, (4) physical activity calorie equivalent label group, and (5) physical activity calorie equivalent label group in which a brochure will be used to inform mothers. Some samples of dairy products, beverages, cakes, and biscuits will be presented. ANOVA and multiple linear regressions will be used to examine the association between the label type and the main consequence (energy of the selected products) and secondary outcome (time).
The effect of the new food labels will be evaluated based on the differences between the calories of selected food groups.

非传染性疾病（NCDs）在全球范围内的患病率正在上升。选择健康食品和进行足够的身体活动是预防 NCDs 的关键因素。食品标签是一种可以在购买时告知消费者选择更健康食品的策略。在这项研究中，我们旨在检查现有标签的状况，并阐明其优缺点。然后，我们将首次在伊朗设计一种体力活动等效卡路里标签，并在乳制品、含糖饮料、蛋糕和饼干等包装产品的一些食品组上对其进行测试。
本研究将分为两个阶段进行。在第 1 阶段，通过对不同群体的母亲、工业家和营养与食品行业专家进行焦点小组讨论和访谈，评估营养成分标签和红绿灯标签，以确定包装产品上现有标签的优缺点。然后，根据母亲的观点初步设计体力活动等效卡路里标签的布局。此后，我们将纳入科学观点，以创建我们新标签的初稿。在第 2 阶段，将随机分配 500 名 6-12 岁学生的母亲到五个组。研究组如下：（1）无营养标签组，（2）当前红绿灯标签组，（3）当前红绿灯标签组，其中将使用宣传册告知母亲，（4）体力活动等效卡路里标签组，以及（5）体力活动等效卡路里标签组，其中将使用宣传册告知母亲。将展示一些乳制品、饮料、蛋糕和饼干的样本。将使用方差分析和多元线性回归来检查标签类型与主要后果（所选产品的能量）和次要结果（时间）之间的关联。
将根据所选食品组的卡路里差异来评估新食品标签的效果。
