Evaluate the use, subjective and objective under-standing of the GDA frontal labeling to assist the population towards making healthy decisions regarding the products they consume.
The use of nu-tritional information contained in products ́ packages (GDA, nutritional information table, and list of ingredients), as well as the subjective and objective comprehension of the GDA.
A total of 43 157 people were interviewed. Amid the labels, the nutritional table was read more frequently (11.1%). 24.6% (IC95%: 23.9-25.3) and 41.2% (IC95%: 40.4-42.1) of the interviewees classified products correctly as not healthy and high in sodium, respectively. These outcomes were smaller between the elderly, lower socioeconomic levels, lower educational levels, and rural areas.
The results show that the GDA labeling is not useful to support the vulnerable population to make healthy decisions.
评估每日摄入量（GDA）正面标签的使用情况、主观和客观理解程度，以帮助人们就所消费的产品做出健康决策。
产品包装中营养信息（GDA、营养信息表和成分列表）的使用情况，以及对GDA的主观和客观理解。
共采访了43157人。在标签中，营养表的阅读频率更高（11.1%）。分别有24.6%（95%置信区间：23.9 - 25.3）和41.2%（95%置信区间：40.4 - 42.1）的受访者正确地将产品分类为不健康和高钠产品。在老年人、社会经济水平较低者、教育水平较低者和农村地区，这些结果较低。
结果表明，GDA标签无助于支持弱势群体做出健康决策。
