含糖饮料警告是减少含糖饮料消费的一项有前途的政策，但目前仍不清楚如何设计警告，以最大限度地提高其对整体和不同人群的影响，包括拉丁裔父母和英语使用率低的父母。2019年，我们将2-12岁儿童的美国父母（n= 1，078，48%拉丁裔，13%英语使用率低）随机分配到一个主题（四个警告之一，或中性对照），他们在三种设计（纯文本，图标和图形）上查看，以评估对含糖饮料各种警告的反应。所有警告主题都被认为比对照更有效（平均差异效应[ADE]范围为1.77至1.84 [5点李克特量表]，所有p<0.001）。所有警告主题也导致对含糖饮料危害的更多思考（所有p<.001）和较低的购买意愿（所有p<.01）。与纯文本警告相比，图标（ADE= 0.18）和图形警告（ADE= 0.30）引起了更高的感知信息有效性，以及对含糖饮料危害的更多思考，更低的感知健康和更低的购买意愿（所有p<0.001）。图标警告（与文字警告）的影响是较强的父母与低英语使用，与那些高英语使用（p= 0.024）。同样，图标（与文本警告）的影响对拉丁裔父母比非拉丁裔父母更强（p= 0.034）。这项实验研究表明，许多警告主题的承诺行为改变，包括图像与警告可以增加警告的功效，特别是在拉丁裔父母和父母与低英语使用。
Sugary drink warnings are a promising policy for reducing sugary drink consumption, but it remains unknown how to design warnings to maximize their impact overall and among diverse population groups, including parents of Latino ethnicity and parents with low English use. In 2019, we randomized US parents of children ages 2-12 (n=1,078, 48% Latino ethnicity, 13% low English use) to one topic (one of four warnings, or a neutral control), which they viewed on three designs (text-only, icon, and graphic) to assess reactions to the various warnings on sugary drinks. All warning topics were perceived as more effective than the control (average differential effect [ADE] ranged from 1.77 to 1.84 [5-point Likert scale], all p<.001). All warning topics also led to greater thinking about harms of sugary drinks (all p<.001) and lower purchase intentions (all p<.01). Compared to text-only warnings, icon (ADE=.18) and graphic warnings (ADE=.30) elicited higher perceived message effectiveness, as well as greater thinking about the harms of sugary drinks, lower perceived healthfulness, and lower purchase intentions (all p<.001). The impact of icon warnings (vs. text warnings) was stronger for parents with low English use, compared to those with high English use (p=.024). Similarly, the impact of icon (vs. text warnings) was stronger for Latino parents than non-Latino parents (p=.034). This experimental study indicates that many warning topics hold promise for behavior change and including images with warnings could increase warning efficacy, particularly among Latino parents and parents with low English use.
