Background/introduction Informing HIV-negative people by people living with HIV (PLWH) about their status might probably have great HIV preventive effect. That is why it’s important to study the factors of HIV disclosure to confidents with different HIV status.

Aim(s)/objectives The goal of the study was to reveal the psychosocial determinants of HIV disclosure to confidents with different HIV status.

Methods In 2013 we surveyed 418 PLWH in Saint Petersburg, Russia. We employed Internalised AIDS-Related Stigma Scale (IA-RSS), SF-36 Health Status Survey, Multidimensional Scale of Perceived Social Support (MPSS), the Lubben Social Network Scale (LSNS). The interview guide also contained the question about HIV status of those people, who were informed about respondents’ HIV status by respondents themselves.

Results The sample was 58% of male (mean age = 34.3 years). An average time of identification of HIV was 6.3 years before the study. Logistic regression model explaining HIV disclosure to people with positive or/and negative HIV status included the average time passed since identification of HIV (OR = 0.989; p ≤ 0.01); self-stigma (IA-RSS) score (OR = 1.336; p ≤ 0.01); general health (SF-36) score (OR = 0.977; p ≤ 0.05), perceived social support provided by friends (MPSS) (OR = 1.323; p ≤ 0.05), family (OR = 1.217; p ≤ 0.01) and friendship network sizes (LSNS) (OR = 0.825; p ≤ 0.01).

Discussion/conclusion Our data suggest that HIV disclosure to confidents with different HIV status is determined by the objective and subjective characteristics of interaction with the other people, as well as the quality of life and maybe disease progress. The study was supported by the Fogarty International Centre at the US NIH, grant No. D43TW001028.
