Consumers’ attitudes before and after the introduction of the Chilean regulation on food labelling

The aim of the present study is to understand how the attitudes towards food labelling in the Chilean population have changed after the introduction of the Chilean law on food labelling and advertising. A computer-assisted telephone interview was conducted in 2012 and 2016, employing the same procedures. The difference in outcomes between 2012 and 2016 was assessed using a logistic regression model. One hundred and sixty-seven subjects responded to both the 2012 and 2016 survey editions (respondents). For both the unadjusted and adjusted analyses, the respondents in 2016 were more likely to be involved in a programme to lose weight and to consider food labelling the most effective intervention introduced to date to promote healthy nutrition. However, no significant differences were reported in both self-reported and objectively assessed understandings of front-of-pack-labelling. Evidence suggests a positive perception among Chileans regarding the effectiveness of the new law.

本研究旨在探究智利民众在智利食品标签与广告相关法律正式实施后，其对食品标签的态度发生了何种变化。本研究于2012年与2016年开展计算机辅助电话访谈，两次调查采用完全一致的流程。随后通过逻辑回归模型，对2012年与2016年的调查结果差异进行评估。共有167名受访者同时参与了2012年与2016年的两轮调查（即重复受访对象）。无论是未校正分析还是校正分析，2016年的受访者参与减重项目的概率均更高，且更倾向于认为食品标签是目前为止推广健康营养最有效的干预手段。不过，在自我报告与客观评估的包装正面标签认知水平上，均未发现显著差异。研究证据表明，智利民众对该项新法规的有效性持积极态度。
