Significant insights from a National survey in China: PrEP awareness, willingness, uptake, and adherence among YMSM students

Abstract

Abstract Introduction Few studies focused on the Pre-Exposure Prophylaxis (PrEP) -related aspects, and the applicability of prior evidence to young men who have sex with men (YMSM) students was unknown. This study aimed to assess the awareness, willingness, uptake, and adherence (AWUA) to PrEP among YMSM students in China and to explore the associated factors with these stages. Methods A cross-sectional survey with a sizable sample of 1151 was conducted among YMSM students aged 16 and above, who self-identified as men who have sex with men(MSM) and resided in mainland China between October 20 and December 20, 2021. The chi-square test and Fisher’s exact test were used for univariate analysis, followed by multivariable logistic regression analysis of influencing factors at all levels. Results According to the cascade analysis approach, 88.71% of the participants were aware of PrEP, among which 66.7% expressed willingness to use it. Among those who were willing to use PrEP, only 13.80% took it, and of those who took it, 44.68% adhered to it. The students taking PrEP were those with higher education (OR = 4.239, 95% CI: 1.334–13.467), residence in pilot cities (OR = 2.791, 95% CI: 1.498–5.198), residence in high-risk areas (OR = 5.082, 95% CI: 2.224–11.612), engagement in multi-person sexual behavior (OR = 2.186, 95% CI: 1.236–3.867), and substance use (OR = 1.908, 95% CI: 1.167–3.118). Furtherly, students with higher adherence to PrEP were likely to have receptive sexual behaviors (OR = 8.702, 95% CI: 2.070-36.592), absence of substance use (OR = 4.468, 95% CI: 1.371–14.561), and uptake of PrEP through daily oral route. (OR = 7.065, 95% CI: 1.699–29.371). Conclusion YMSM students exhibit distinct patterns of “high awareness, low willingness, low uptake, and low adherence” to PrEP. Strategies for reduction in the acquisition of HIV prioritizing the current features of utilizing PrEP were urgently warranted.
