The pervasiveness of explicit and implicit weight bias (WB) defined as negative stereotypes and prejudice regarding one's weight has been observed among individuals of all weight categories. As a source of WB, health messages have been discussed due to reinforcing stigmatizing notions. The present study sought to investigate whether health messages (i.e., eat healthy, become physically active) have the potential to increase explicit and implicit WB. Participants ( = 144) from the community were randomized to either an experimental group (EG) or a control group (CG). While the EG was presented with health messages, the CG was presented with neutral information. Before and after manipulation, participants completed measures of explicit and implicit WB. Paired samples -test revealed no differences in explicit WB after manipulation, however, a small effect decrease of implicit WB in the EG but not in the CG was found. This study provided evidence that health messages might have differential impact to change WB. According to dual-model approaches, explicit and implicit WB tap into two different information processing systems, and thus were differentially affected by health messages. Brief exposure to health messages might have the potential to contribute to health behavior and to mitigate implicit WB.
明确和隐性体重偏见（WB）被定义为对一个人体重的负面刻板印象和偏见，在所有体重类别的个体中都普遍存在。作为WB的一个来源，健康信息因其强化污名化观念而受到讨论。本研究旨在调查健康信息（即健康饮食、积极锻炼）是否有可能增加明确和隐性WB。来自社区的参与者（n = 144）被随机分为实验组（EG）或对照组（CG）。当向EG呈现健康信息时，向CG呈现中性信息。在操纵前后，参与者完成了明确和隐性WB的测量。配对样本t检验显示操纵后明确WB没有差异，然而，发现EG中隐性WB有小幅下降，而CG中没有。这项研究提供了证据表明健康信息可能对改变WB有不同的影响。根据双模型方法，明确和隐性WB涉及两个不同的信息处理系统，因此受到健康信息的影响也不同。短暂接触健康信息可能有促进健康行为和减轻隐性WB的潜力。
