Despite growing awareness of the experiences of LGBTQ+ communities, there has been relatively little attention given to the issues of exclusion and marginalization that occur within these communities. This gap is particularly significant given the health disparities faced by LGBTQ+ individuals from minority ethnic backgrounds. To address this gap, this paper examines the experiences of intracommunity intersectional discrimination among sexual minority men from minority ethnic backgrounds. Additionally, it proposes an intracommunity stress-coping model that explains how individuals may turn to smoking as a coping mechanism to manage the psychological impact of discrimination within LGBTQ+ communities. This paper is based on data collected from a national behavioral surveillance study in Australia, which included 1056 cisgender sexual minority men of Asian backgrounds. A substantial proportion of participants reported experiencing discrimination based on body size (39.9%) or skin color (36.3%) within LGBTQ+ communities. While the severity of discrimination was found to be positively related to psychological distress, the analysis also revealed the cumulative effects of discrimination based on intersecting identities. Specifically, individuals who experienced discrimination across multiple intersecting identities reported higher rates of psychological distress and smoking behavior. The positive associations between intracommunity intersectional discrimination and smoking behavior were mediated by psychological distress. Given the detrimental impact of intracommunity intersectional discrimination, it is crucial to raise awareness about the stressors within LGBTQ+ communities. Practitioners in mental health services and smoking cessation programs should be equipped with the knowledge and skills to effectively address the intracommunity stress experienced by Asian sexual minority men with multiple marginalized identities.
