Impact of the COVID-19 pandemic on sexual behaviour and welfare of HIV preexposure prophylaxis users: a mixed-method study.

COVID-19 pandemic can affect people using HIV preexposure prophylaxis (PrEP). To assess its consequences on PrEP users' sexual behaviour and welfare, we conducted a mixed-method study. A self-administered questionnaire was given to PrEP users during scheduled consultation in Tourcoing Hospital from February to May 2021. In addition, a qualitative study included 14 participants who took part in semi-structured in-depth interviews (IDIs). Ninety-four PrEP users completed the questionnaire. During lockdown, 62% of participants continued PrEP. After lockdown release, the average number of sexual intercourses and partners increased from 6 ± 12 to 13 ± 17 intercourses/month ( < 0.001) and from 3 ± 11 to 11 ± 34 partners/month ( < 0.001). Similarly, the proportion of PrEP users who engaged in group sex, sex with alcohol or chemsex increased respectively from 28% to 55% ( < 0.001), 28% to 45% ( < 0.001) and 28% to 38% ( < 0.001). Analysis of IDIs revealed emotional deprivation and sexual frustration during the lockdown. After its release, frequent clandestine chemsex parties and curfew forcing overnight stay increased fears of intimate violence and overdoses. In conclusion, PrEP users reduced their sexual activity during the lockdown. Its release led to an increase in sexual risk-taking. Social distancing measures could favour medical and social harm of sexual risk-taking.
