目的：为了评估的影响，在第一个月后的日期完全遵守乌拉圭食品行业在公民意识，自我报告的使用和理解营养informations.Design的能力的营养警告：目前的工作包括两个在线研究，进行之前（研究1）和第一个月后的日期完全遵守食品行业（研究2）。在研究2中，使用仅限事后的设计来评估对政策的认识、食品包装上营养警告的暴露情况以及自我报告的在做出购买决定时使用警告的情况。在研究1和2中，使用了一个只有控制组的实验设计来评估营养警告对理解营养信息的影响。设置：乌拉圭，拉丁美洲国家之一，最近实施了营养警告。参与者：使用针对乌拉圭成年用户的Facebook广告招募了1772名参与者的非概率样本。乌拉圭在全面遵守规定之日后的第一个月内，人们对营养警告的认识很高，自我报告的使用情况也很好。此外，前后对比显示，警示的实施提高了公民利用营养信息比较产品的能力，以及识别糖、脂肪、饱和脂肪和钠含量超标的产品的能力。目前的研究证实了实验研究的结果，并提供了额外的证据，支持实施营养警告作为公共政策之一，可以促进来解决肥胖和非传染性疾病。
Objective: To assess the effects of nutritional warnings during the first month after the date of full compliance by the food industry in Uruguay in terms of citizen awareness, self-reported use and ability to understand nutritional information.Design: The present work encompassed two online studies, conducted before (Study 1) and during the first month after the date of full compliance by the food industry (Study 2). An after-only design was used to assess awareness of the policy, exposure to nutritional warnings on food packages and self-reported use of warnings for making purchase decisions in Study 2. An after-only with control group experimental design was used to assess the effect of nutritional warnings on understanding of nutrition information in Studies 1 and 2.Setting: Uruguay, one of the Latin American countries, that has recently implemented nutritional warnings.Participants: A non-probabilistic sample of 1772 participants was recruited using Facebook advertisements targeted at Uruguayan adult users.Results: High awareness and self-reported use of nutritional warnings during the first month after the date of full compliance in Uruguay were observed. In addition, the before and after comparison showed that the implementation of warnings increased citizens' ability to use nutritional information to compare products and to identify products with excessive content of sugar, fat, saturated fat and sodium.Conclusions: The current study confirms results from experimental studies and provides additional evidence to support the implementation of nutritional warnings as one of the public policies that can contribute to tackle obesity and non-communicable diseases.
