包装正面（FOP）营养标签是鼓励人们选择健康食品的战略之一，有助于应对成人和儿童超重和肥胖的日益增加的负担。本研究的目的是评估不同的FOP标签对巴西儿童和父母的健康感知的影响。6 - 12岁的儿童（n = 318）和父母（n = 278），不同的社会经济地位，他们认为健康的8种食品针对儿童使用7点量表（1 =不健康，7 =非常健康）。参与者被随机分配到FOP营养标签的三组之一：每日指导量（GDA），交通灯系统（TLS）和警告系统。数据采用方差分析进行分析。对于父母来说，带有警告系统的产品被评为比含有GDA的产品更不健康，而TIS与其他两个系统没有显着差异。年龄和社会经济地位的影响FOP标签对儿童的健康感知的效果。只有9 - 12岁的中/高社会经济地位的儿童受到FOP标签的影响：与GDA系统相比，警告系统和TLS降低了对霜冻玉米片的健康感知。这些结果表明，指令性和半指令性FOP有可能修改针对儿童的产品的健康感知，并强调需要研究个体变量（如年龄和社会经济地位）对FOP标签感知的调节作用。
The inclusion of front of pack (FOP) nutrition labels is one of the strategies that has been proposed to encourage people to make healthful food choices, helping to cope with the increasing burden of overweight and obesity among adults and children. The aim of this study was to evaluate the effect of different FOP labels on Brazilian children and parents' healthfulness perception. Children aged 6-12 years (n = 318) and parents (n = 278) with different socio-economic status rated their perceived healthfulness of eight food products targeted at children using a 7-point scale (1 = not healthful and 7 = very healthful). Participants were randomly allocated into one of the three groups of FOP nutrition labels: Daily Guideline Amounts (GDA), Traffic Light System (TLS) and warning system. Data were analyzed using analysis of variance. For parents, products with the warning system were rated significantly less healthful than those containing the GDA, whereas the TIS did not significantly differ from the other two systems. Age and socio-economic status influenced the effect of FOP labels on children's perceived healthfulness. Only 9-12 years old children from middle/high socio-economic status were influenced by FOP labels: the warning system and TLS reduced healthfulness perception of frosted corn flakes compared to the GDA system. These results suggest that directive and semi-directive FOP have the potential to modify healthfulness perception of products targeted at children and stress the need to study the modulating effect of individual variables such as age and socio-economic status on the perception of FOP labels.
