Prevalence and associated factors of inhaled nitrites use among men who have sex with men in Beijing, China

Abstract Background Inhaled nitrites are commonly used by men who have sex with men (MSM) in western countries. As such compounds are not illicit, they are widely available in China. Recent studies have documented a high prevalence of inhaled nitrites use in this population. Methods Snowball sampling was used to recruit 576 MSM in Beijing, China, who completed an anonymous face-to-face interview. Results Of the participants, 49.8% had heard of “Rush” or “inhaled nitrites”. The prevalence of use in the last three months was 28.3% among all participants and 56.8% among those with awareness about the compounds. A stepwise model found that age group (26–35 years old, ORm = 3.91; ≤25 years old, ORm = 3.05; reference group: >35 years old, P P P P P P P Conclusions The prevalence of inhaled nitrites use was high. It may further increase sharply among MSM in China when awareness becomes more common. Cognitive variables derived from the HBM provided a useful framework for designing interventions at structural, inter-personal and individual levels. Policy changes should also be considered.
