To test whether countermarketing messages for sugary drinks lead to lower intentions to consume sugary drinks and less perceived weight stigma than health education messages. In August 2023, we conducted an online randomized controlled trial with US adults (n = 2169). We assessed the effect of countermarketing messages, health education messages, and neutral control messages on intentions to consume sugary drinks and perceived weight stigma. Both countermarketing messages (Cohen = -0.20) and health education messages ( = -0.35) led to lower intentions to consume sugary drinks than control messages (s < .001). However, both types of messages elicited more perceived weight stigma than control messages (s = 0.87 and 1.29, respectively; s < .001). Countermarketing messages were less effective than health education messages at lowering intentions to consume sugary drinks ( for countermarketing vs health education = 0.14) but also elicited less perceived weight stigma than health education messages ( = -0.39; s < .01). Countermarketing messages show promise for reducing sugary drink consumption while eliciting less weight stigma than health education messages, though they may need to be refined further to minimize weight stigma and maximize effectiveness.

为了测试针对含糖饮料的反营销信息是否比健康教育信息更能降低人们饮用含糖饮料的意愿和感知到的体重污名化程度。2023 年 8 月，我们在美国成年人中进行了一项在线随机对照试验（n=2169）。我们评估了反营销信息、健康教育信息和中性对照信息对饮用含糖饮料的意愿和感知到的体重污名化的影响。反营销信息（Cohen's d=-0.20）和健康教育信息（ = -0.35）都比对照信息导致更低的饮用含糖饮料的意愿（s<0.001）。然而，这两种信息都比对照信息引起更多的感知体重污名化（s=0.87 和 1.29，分别；s<0.001）。反营销信息在降低饮用含糖饮料的意愿方面不如健康教育信息有效（对于反营销与健康教育的差异 = 0.14），但也比健康教育信息引起的感知体重污名化程度更小（ = -0.39；s<0.01）。反营销信息显示出在减少含糖饮料消费的同时引起较少体重污名化的潜力，尽管它们可能需要进一步改进，以最大限度地减少体重污名化并提高效果。ClinicalTrials.gov NCT05953194。（. 2024；114(12):1354-1364. https://doi.org/10.2105/AJPH.2024.307853）。
