Post-lockdown Rebounding High-risk Behaviors and HIV Testing Among MSM in China in the Era of the COVID-19 Pandemic.

Background: Lockdown measures for controlling the COVID-19 epidemic were enforced in China between January and May 2020. Previous studies showed a decrease in HIV high- Risk Behaviors (HRBs) and updated testing during the lockdown, but little is known about these behaviors during the post-lockdown period.

Objective: We conducted quantitative and qualitative assessments of HIV-related behaviors among MSM during the lockdown and post-lockdown periods in Changsha, south-central China.

Methods: Face-to-face structured interviews with open-ended questions were conducted using the TimeLine Follow Back (TLFB) method for collecting retrospective data on frequencies of HRBs and testing. McNemar's Chi-square test and Wilcoxon signed-rank test were used to comparing frequencies of behaviors between lockdown (January-May 2020) and post-lockdown periods (June- October 2020). Content analysis was used to analyze qualitative data on the reasons for rebounding HRBs and testing.

Results: Of 159 MSM participants, 64% had at least one HRB during the post-lockdown period. Men had increased condomless sex (from 24% to 35%), multiple partners (23% to 35%), and substance abuse (16% to 27%) between the two study periods due to the negative emotions and increased use of social networks during the lockdown. HIV testing frequency also increased from 37% to 66% due to resuming routine testing services in the community-based organizations and increased HRBs among MSM during post-lockdown.

Conclusion: After lifting the lockdown measures, MSM had rebounding HRBs and uptake of testing. Effective preventive measures and healthcare services should be available to MSM after the lockdown measures are lifted.
