Research on the relative influence of package features on children's perception of food products is still necessary to aid policy design and development. The aim of the present work was to evaluate the relative influence of two front-of-pack (FOP) nutrition labelling schemes, the traffic light system and Chilean warning system, and label design on children's choice of two popular snack foods in Uruguay, wafer cookies and orange juice. A total of 442 children in grades 4 to 6 from 12 primary schools in Montevideo (Uruguay) participated in the study. They were asked to complete a choice-conjoint task with wafer cookies and orange juice labels, varying in label design and the inclusion of FOP nutrition information. Half of the children completed the task with labels featuring the traffic-light system (n = 217) and the other half with labels featuring the Chilean warning system (n = 225). Children's choices of wafer cookies and juice labels was significantly influenced by both label design and FOP nutritional labels. The relative impact of FOP nutritional labelling on children's choices was higher for the warning system compared to the traffic-light system. Results from the present work stress the need to regulate the design of packages and the inclusion of nutrient claims, and provide preliminary evidence of the potential of warnings to discourage children's choice of unhealthful products.
研究包装特征对儿童食品认知的相对影响，对于辅助政策设计与制定仍很有必要。本研究的目的是评估两种包装正面（FOP）营养标签方案，即红绿灯系统和智利警告系统，以及标签设计对乌拉圭两种受欢迎的休闲食品——威化饼干和橙汁——儿童选择的相对影响。来自乌拉圭蒙得维的亚12所小学的442名四至六年级学生参与了该研究。他们被要求完成一项关于威化饼干和橙汁标签的选择联合任务，标签在设计以及是否包含FOP营养信息方面存在差异。一半儿童完成的任务标签采用红绿灯系统（n = 217），另一半儿童完成的任务标签采用智利警告系统（n = 225）。儿童对威化饼干和果汁标签的选择受到标签设计和FOP营养标签的显著影响。与红绿灯系统相比，警告系统的FOP营养标签对儿童选择的相对影响更大。本研究结果强调了规范包装设计和营养声称标注的必要性，并为警告标签在抑制儿童选择不健康产品方面的潜力提供了初步证据。
