Minorities and marginalized groups have increasingly become the target of discriminatory actions related to the COVID-19 pandemic. Detailed information about the manifestation of COVID-related discrimination is required to develop preventive actions that are not stigmatizing for such groups. The present study investigates experiences of perceived discrimination related to COVID-19 and its socio-cultural correlates in a culturally diverse sample of adults in Quebec (Canada). An online survey was completed by 3273 Quebec residents (49 % 18−39 years old; 57 % female; 49 % White). We used multivariate binomial logistic regression models to assess prevalence of COVID-related discrimination and to investigate socio-cultural correlates of reasons and contexts of discrimination. COVID-related discrimination was reported by 16.58 % of participants. Non-white participants, health-care workers and younger participants were more likely to experience discrimination than White, unemployed and older participants, respectively. Discrimination was reported primarily in association with participants’ ethno-cultural group, age, occupation and physical health and in the context of public spaces. Participants of East-Asian descent and essential workers were more likely to report discrimination because of their ethnicity and occupation, respectively. Although young people experienced discrimination across more contexts, older participants were primarily discriminated in the context of grocery stores and because of their age. Our findings indicate that health communication actions informed by a social pedagogy approach should target public beliefs related to the association of COVID-19 with ethnicity, age and occupation, to minimize pandemic-related discrimination. Visible minorities, health-care workers and seniors should be protected and supported, especially in public spaces.

少数群体和边缘化群体越来越多地成为与 COVID-19 大流行相关的歧视性行动的目标。需要有关 COVID 相关歧视表现的详细信息，以制定不会对此类群体造成污名化的预防措施。本研究调查了魁北克（加拿大）文化多样化的成年人样本中与 COVID-19 相关的感知歧视的经历及其社会文化相关性。3273 名魁北克居民（49% 18-39 岁；57% 女性；49% 白人）完成了在线调查。我们使用多元二项式逻辑回归模型来评估与 COVID 相关的歧视的普遍程度，并调查歧视原因和背景的社会文化相关性。16.58% 的参与者报告了与 COVID 相关的歧视。非白人参与者、医护人员和年轻参与者分别比白人、失业者和年长参与者更容易遭受歧视。据报告，歧视主要与参与者的民族文化群体、年龄、职业和身体健康以及公共场所的背景有关。东亚血统的参与者和基本工人更有可能报告分别因其种族和职业而受到歧视。尽管年轻人在更多情况下经历过歧视，但年长的参与者主要是在杂货店的情况下以及因为他们的年龄而受到歧视。我们的研究结果表明，以社会教育学方法为依据的健康传播行动应针对与 COVID-19 与种族相关的公众信念，年龄和职业，以尽量减少与流行病相关的歧视。应保护和支持有色人种、医护人员和老年人，尤其是在公共场所。
