Dietary practices are a key behavioral factor in chronic disease prevention; one strategy for improving such practices population-wise involves front-of-package labels (FoPL). This online randomized study, conducted in a quota-based sample of 1159 Polish adults (mean age = 40.9 ± 15.4 years), assessed the objective understanding of five FoPL: Health Star Rating, Multiple Traffic Lights, NutriScore, Reference Intakes (RI) and Warning Label. Objective understanding was evaluated by comparing results of two nutritional quality ranking tasks (without/with FoPL) using three food categories (breakfast cereals, cakes, pizza). Associations between FoPL exposure and objective understanding were assessed via multivariable ordinal logistic regression. Compared to RI and across food categories, significant improvement in objective understanding was seen for NutriScore (OR = 2.02; 95% CI: 1.41-2.91) and Warning Label (OR = 1.61; 95% CI: 1.12-2.32). In age-stratified analyses, significant improvement in objective understanding compared to RI emerged mainly among adults aged 18-30 years randomized to NutriScore (all food categories: OR = 3.88; 95% CI: 2.04-7.36; cakes: OR = 6.88; 95% CI: 3.05-15.51). Relative to RI, NutriScore was associated with some improvement in objective understanding of FoPL across and within food categories, especially among young adults. These findings contribute to the ongoing debate about an EU-wide FoPL model.
饮食习惯是慢性病预防中的一个关键行为因素；从人群层面改善此类习惯的一种策略涉及包装正面标签（FoPL）。这项在线随机研究以1159名波兰成年人（平均年龄 = 40.9 ± 15.4岁）的配额抽样样本进行，评估了对五种包装正面标签的客观理解：健康星级评定、多重红绿灯标识、营养评分、参考摄入量（RI）和警告标签。通过比较使用三类食品（早餐谷物、蛋糕、披萨）的两项营养质量排名任务（无/有包装正面标签）的结果来评估客观理解。通过多变量有序逻辑回归评估包装正面标签暴露与客观理解之间的关联。与参考摄入量相比，在各类食品中，营养评分（OR = 2.02；95% CI：1.41 - 2.91）和警告标签（OR = 1.61；95% CI：1.12 - 2.32）的客观理解有显著改善。在按年龄分层的分析中，与参考摄入量相比，客观理解的显著改善主要出现在随机分配到营养评分组的18 - 30岁成年人中（所有食品类别：OR = 3.88；95% CI：2.04 - 7.36；蛋糕：OR = 6.88；95% CI：3.05 - 15.51）。相对于参考摄入量，营养评分与各类食品及食品内部包装正面标签的客观理解的一些改善相关，尤其是在年轻人中。这些发现为正在进行的关于全欧盟范围包装正面标签模型的辩论提供了参考。
