目的：研究包装正面营养信息对2个收入水平的超加工产品健康感知的影响。设计：采用参与者间设计，比较不同包装正面营养信息方案的超加工产品的健康感知（每日指导量系统、交通灯系统和单色交通灯系统）。参与者：共有300人来自乌拉圭蒙得维的亚的100名（年龄18-70岁，75%为女性）参与了这项研究;一半是中高收入人群，另一半是低收入人群。研究人员向参与者展示了每种产品的标签，并要求他们对自己的健康状况以及每种产品的食用频率进行评分。分析：结果采用方差分析进行统计学显著性分析（P < .05）。结果：低收入参与者认为超加工产品比中高收入参与者更健康（P < .05）。低收入参与者的最低感知健康得分是在具有彩色和单色交通灯系统的产品中获得的，而没有显着差异（P > 0.05）的方案之间被发现为中等和高收入的参与者。结论和影响：营养教育计划旨在提高低-因此，提高高收入人群对这些产品的营养成分及其对健康的潜在负面影响的认识似乎是必要的。虽然半指导性的包装前营养信息的纳入降低了低收入人群的健康感，但似乎不太可能影响他们对这些产品的看法。
Objective: To examine the influence of front-of-pack nutrition information on the perception of healthfulness of ultra-processed products across 2 income levels.Design: A between-participants design was used to compare healthfulness perception of ultra-processed products featuring different front-of-pack nutrition information schemes (guideline daily amount system, traffic light system, and monochromatic traffic light system).Participants: A total of 300 people (aged 18-70 years, 75% female) from Montevideo, Uruguay, participated in the study; half were middle-or high-income people and the other half were low-income people.Main Outcome Measures: Participants were shown the labels of each product and asked to rate their perceived healthfulness and the frequency with which each product should be consumed.Analysis: Results were analyzed using analysis of variance for statistical significance (P < .05).Results: Low-income participants perceived ultra-processed products to be significantly (P < .05) more healthful than did middle-and high-income participants. The lowest perceived healthfulness scores for low-income participants were obtained for products featuring the colored and monochromatic traffic light system whereas no significant differences (P > .05) among schemes were found for middle -and high-income participants.Conclusions and Implications: Nutrition education programs aimed at increasing low-income people's knowledge of the nutritional composition of these products and their potential negative effects on health seem to be necessary. Although the inclusion of semidirective front-of-pack nutrition information decreased the perceived healthfulness of low-income people, it seemed unlikely to influence how they perceive these products.
