Point-of-sale (POS) interventions that prompt consumers to more critically evaluate sugary drinks could encourage reduced consumption of these drinks and reinforce public health campaign messages. This study tested whether: (i) POS nutrition information and health warnings about sugary drinks promote healthier drink choices and (ii) impacts of prominent POS signs on drink choices vary based on participants' self-reported prior exposure to a sugary drink public health campaign. In an online experiment, 3034 Australian adults aged 18-59 years who were past-week sugary drink consumers were randomly assigned to one of five POS signage conditions (no signage (control); sugar content of specific beverages; Health Star Rating of specific beverages; generic text health warning about sugary drinks; generic graphic health warning about sugary drinks) and shown their randomly assigned POS sign alone, then alongside a drinks product display and asked to select which drink they would choose to buy. The proportion selecting a sugary drink was significantly lower among participants who viewed either the sugar content (29%), Health Star Rating (33%) or graphic health warning (34%) signs compared to those who saw no sign (43%). These effects held for participants who did not recall previously seeing the campaign; however, for participants with self-reported prior exposure to the campaign, POS signs did not promote significant reductions in sugary drink choices. POS signage has the potential to shift consumers away from choosing sugary drinks and could complement mass media campaigns by reaching people who may not otherwise be exposed to sugary drink public health messages.
销售点（POS）干预措施可以促使消费者更批判性地评估含糖饮料，从而鼓励减少这些饮料的消费，并强化公共卫生运动的信息。本研究测试了以下两种情况：（i）POS 营养信息和含糖饮料健康警示是否促进更健康的饮料选择；（ii）POS 标志对饮料选择的影响是否因参与者自述之前接触过含糖饮料公共卫生运动而异。在一项在线实验中，3034 名年龄在 18-59 岁之间的澳大利亚成年人（过去一周内饮用含糖饮料的消费者）被随机分配到五种 POS 标志条件之一（无标志（对照）；特定饮料的含糖量；特定饮料的健康星级评分；关于含糖饮料的通用文字健康警示；关于含糖饮料的通用图形健康警示），然后单独展示他们随机分配的 POS 标志，然后展示饮料产品展示，并要求他们选择要购买的饮料。与看到无标志（43%）的参与者相比，看到糖含量（29%）、健康星级评分（33%）或图形健康警示（34%）标志的参与者选择含糖饮料的比例明显更低。对于那些没有回忆起之前看到过该运动的参与者来说，这些效果仍然存在；然而，对于那些自述之前接触过该运动的参与者来说，POS 标志并没有显著减少含糖饮料的选择。POS 标志有可能使消费者远离选择含糖饮料，并且可以通过接触可能没有接触过含糖饮料公共卫生信息的人群来补充大众媒体运动。
