Bias-based bullying (e.g., bullying related to race, weight, sexual orientation) is a common experience among youth, yet few school-based prevention programs explicitly address this type of bullying. This study explores whether schools that offer diversity education activities have lower rates of bias-based bullying among students compared to schools that do not offer these activities. Data came from two sources: the 2018 CDC School Profiles Survey (N = 216 schools) and the 2019 Minnesota Student Survey (N = 64,510 students). Multilevel logistic regression tested associations between diversity education activities (diversity clubs, lessons, or special events) and eight types of bias-based bullying among students, with attention to effect modification by relevant demographic characteristics. Students attending schools that offer a wider variety of diversity education opportunities had significantly lower odds of bullying about race, ethnicity, or national origin among boys of color (OR = 0.89, CI: 0.80, 1.00), about sexual orientation for gay, bisexual, and questioning boys (OR = 0.81, CI: 0.67, 0.97), and about disability for boys with a physical health problem (OR = 0.86, CI: 0.76, 0.99). Attending a school with more types of diversity education activities may protect vulnerable students against specific types of bias-based bullying and advance health equity. A diversity education is recommended as a key component of antibullying efforts and policy.

基于偏见的欺凌（例如，与种族、体重、性取向有关的欺凌）在青少年中很常见，但很少有基于学校的预防计划明确解决这种类型的欺凌。本研究探讨了与不提供这些活动的学校相比，提供多元化教育活动的学校是否具有较低的学生偏见欺凌率。数据来自两个来源：2018 年 CDC 学校概况调查（N = 216 所学校）和 2019 年明尼苏达州学生调查（N= 64,510 名学生）。多级逻辑回归测试了多样性教育活动（多样性俱乐部、课程或特殊活动）与学生中八种基于偏见的欺凌之间的关联，并注意相关人口特征的影响修正。就读于提供更多多样性教育机会的学校的学生，在有色男孩（OR = 0.89, CI: 0.80, 1.00）、关于同性恋、双性恋、和询问男孩（OR = 0.81，CI：0.67，0.97），以及有身体健康问题的男孩的残疾（OR= 0.86，CI：0.76，0.99）。就读具有更多类型的多元化教育活动的学校可以保护弱势学生免受特定类型的基于偏见的欺凌并促进健康公平。建议将多元化教育作为反欺凌工作和政策的关键组成部分。
