Latinos suffer from health disparities associated with excessive consumption of sugar-sweetened beverages. This study aimed to test the effectiveness of messaging using critical health communication approaches and delivered by two narrative modalities (video and comic book) with similar content that aims to empower Latinos to advocate for social change and to make individual behavior change related to sugary beverage consumption.
Participants ( = 129 Mexican American women between 18 and 29 years) completed an online survey before and after exposure to an embedded stimulus. Participants were randomly assigned to a stimulus, a narrative message in video or comic book format, both developed using critical health communication approaches that focused on individual harms and social causes of sugary beverage consumption.
Paired sample t-test results showed that both narrative messages increased intentions to reduce sugary beverage consumption (Video: < 0.01; d = 0.43; Comic: = 0.03; d = 0.28). Both groups also demonstrated significant improvements in sugary beverage-related media literacy (Video: = 0.01, d = 0.34; Comic: = 0.05, d = 0.25), public health literacy (Video: = 0.05, d = 0.24; Comic: = 0.01, d = 0.32), and empowerment to engage in sugary beverage-related community movements (Video: = 0.003, d = 0.38; Comic: = 0.034, d = 0.27).
This study provides initial evidence indicating the effectiveness of narrative messages in two modalities using critical health communication for promoting individual behavioral intention and social activation in reducing sugary beverage consumption.
拉丁裔人群因过度摄入含糖饮料而面临健康差距问题。本研究旨在测试使用关键健康传播方法并通过两种具有相似内容的叙述方式（视频和漫画书）传递信息的效果，旨在使拉丁裔人群能够倡导社会变革，并就含糖饮料消费做出个人行为改变。
129 名年龄在 18 至 29 岁之间的墨西哥裔美国女性参与者在接触嵌入式刺激物之前和之后完成了在线调查。参与者被随机分配到刺激物、视频或漫画书格式的叙述信息中，这些信息都是使用重点关注个人伤害和含糖饮料消费的社会原因的关键健康传播方法开发的。
配对样本 t 检验结果表明，两种叙述信息都增加了减少含糖饮料消费的意愿（视频： < 0.01；d = 0.43；漫画： = 0.03；d = 0.28）。两组参与者在含糖饮料相关媒体素养（视频： = 0.01，d = 0.34；漫画： = 0.05，d = 0.25）、公众健康素养（视频： = 0.05，d = 0.24；漫画： = 0.01，d = 0.32）和参与含糖饮料相关社区运动的能力（视频： = 0.003，d = 0.38；漫画： = 0.034，d = 0.27）方面也均有显著提高。
本研究提供了初步证据，表明使用关键健康传播方法的两种叙述方式在促进个人行为意图和减少含糖饮料消费方面的社会激活方面具有有效性。
