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.

销售点营养信息和健康警告可以鼓励减少对含糖饮料的偏好吗？：一项实验研究

提示消费者更严格地评估含糖饮料的销售点 (POS) 干预措施可以鼓励减少这些饮料的消费并加强公共卫生运动信息。该研究测试了：（i）关于含糖饮料的 POS 营养信息和健康警告是否促进了更健康的饮料选择，以及（ii）显着的 POS 标志对饮料选择的影响是否因参与者自我报告的先前接触过含糖饮料公共卫生活动而异. 在一项在线实验中，3034 名 18-59 岁的澳大利亚成年人过去一周是含糖饮料消费者，他们被随机分配到五种 POS 标牌条件之一（无标牌（对照）；特定饮料的含糖量；特定饮料的健康星级评级；关于含糖饮料的通用文本健康警告；关于含糖饮料的通用图形健康警告）并单独展示他们随机分配的 POS 标志，然后在饮料产品展示旁边，并要求他们选择购买哪种饮料。与没有看到标志的参与者 (43%) 相比，查看含糖量 (29%)、健康星级评级 (33%) 或图形健康警告 (34%) 标志的参与者选择含糖饮料的比例显着降低。这些效果适用于不记得之前看过该活动的参与者；然而，对于自我报告之前接触过该活动的参与者，POS 标志并没有促进含糖饮料选择的显着减少。
