In China, HIV transmission increasingly affected men who have sex with men (MSM) and those in heterosexual marriages. This study addressed a critical gap in understanding HIV and sexual orientation disclosure within conventional heterosexual marriages, framed within a family-oriented cultural context. Heterosexually married MSM living with HIV (HIV+ MMSM) faced complex identity dynamics and interactions between “gay circles” and marital life. Such disclosure was fraught with potential repercussions, including accusations of “marriage fraud”, HIV-related stigma, and divorce. This descriptive qualitative study, conducted in 2022, aimed to explore the common factors influencing HIV status disclosure to wives among Chinese HIV+ MMSM. Sixteen semi-structured interviews were conducted to analyze the factors related to the disclosure process model. Four key themes emerged: (a) concern for wives’ well-being, (b) perceived marriage strength, (c) the degree of social support they had, and (d) a desire to maintain their status in a heterosexual society. The decision to (non)disclose was shaped by both approach-focused and avoidant-focused goals related to these four themes. The findings underscored the need for culturally sensitive strategies that balance family dynamics, stigma reduction, and HIV care management, emphasizing tailored approaches to effectively support this population.
