Nitrite Inhalants Use and HIV Infection among Men Who Have Sex with Men in China

Abstract EN

Objective.

This is the first study in China to examine the use of nitrite inhalants and its correlates among men who have sex with men (MSM) in Beijing, China.

Methods.

A cross-sectional survey was conducted in 2012.

Structured interviews collected data on demographics, sexual and drug use behaviors, and the use of HIV services.

Blood specimens were collected and tested for HIV and syphilis.

Results.

A total of 400 MSM eligible for the study were between 19 and 63 years of age and overall HIV prevalence was 6.0% (9.0% among nitrite inhalant users and 3.3% among nonusers).

Nearly half (47.3%) of them reported ever using nitrite inhalants and 42.3% admitted using nitrite inhalants in the past year.

Multivariable logistic analysis revealed that ever using nitrite inhalants in the past was independently associated with being aged ≤25 years, having higher education attainment, seeking sex via Internet, having casual partners in the past three months, and being HIV positive.

Conclusion.

The use of nitrite inhalants was alarmingly prevalent among MSM in Beijing.

The independent association of the nitrite inhalant use with more casual sex partners and HIV infection underscored the need for intervention and prevention of nitrite inhalant use.
