Acceptability of Pre-Exposure Prophylaxis and Non-Occupational Post-Exposure Prophylaxis among Men Who Have Sex with Men in Guilin, China

Abstract

Pre-exposure prophylaxis (PrEP) and non-occupational post-exposure prophylaxis (nPEP) are both effective strategies for preventing HIV. There is limited information about the acceptability of these prevention measures in undeveloped areas of China. We aimed to examine the acceptability of PrEP and nPEP and their determinants among men who have sex with men (MSM). 219 MSM were recruited in Guilin, China. In total, 28.6% (95% CI: 20.0–41.0) and 35.9% (95% CI: 27.3–49.5) of the participants had heard of PrEP and nPEP, respectively, while 57.0% (95% CI: 43.1–68.2) and 58.6 (95% CI:44.8–68.8) reported they would be willing to use PrEP and nPEP after the methods were explained. A higher acceptability of PrEP was seen among participants who were previously married (aOR = 3.30; 95% CI: 1.22–9.19), working as a laborer (aOR = 5.13; 95% CI: 1.64–17.59), migrant workers/farmers (aOR = 2.56; 95% CI: 1.15–5.79), government employees (aOR = 4.76; 95%CI: 1.80–13.02), had higher social support (aOR = 1.05; 95% CI: 1.03–1.08), and had been previously tested for HIV (aOR = 2.79; 95% CI: 1.36–5.94). A higher acceptability of nPEP was associated with those having higher social support (aOR = 1.06; 95% CI: 1.04–1.09), not knowing their sexual partner’s HIV status (aOR = 2.72; 95% CI: 1.23–6.12), and having a prior HIV test (aOR = 5.53; 95% CI: 2.58–12.51). PrEP and nPEP are acceptable, especially among MSM with higher social support and had received a previous HIV test. Effective education and different dissemination strategies to promote the acceptance of PrEP and nPEP among MSM are needed.
