HIV testing uptake, enablers, and barriers among African migrants in China: A nationwide cross-sectional study.

Background: African migrants in China face social, structural, and cultural barriers to human immunodeficiency virus (HIV) testing with scarce information on their HIV testing behaviours. This study estimated the prevalence of HIV testing and its social and behavioural correlates to understand how to better provide HIV testing services for African migrants living in China. Methods: We conducted a national cross-sectional survey among adult African migrants who lived in China for more than one month between January 19 to February 7, 2021. The survey was disseminated online through six African community organizations and via participant referrals. We collected data on HIV testing behaviours and history of HIV testing, social, and cultural factors and applied univariate and multivariable logistic regression to identify testing correlates. Results: Among a total of 1305 participants, 72.9% (n = 951/1305) tested for HIV during their stay in China and yielded a self-reported HIV prevalence of 0.4% (n = 4/951). The most common reason for HIV testing was to comply with Chinese residence policy requirements (88.5%, n = 842/951); for not testing was "no need to be tested" (79.4%, n = 281/354). We found most African migrants have experienced low acculturation stress (54.5%, n = 750/1305), low social discrimination (65.6%, n = 856/1305), have a moderate stigma towards HIV (54.3%, n = 709/1305), and low community engagement around sexual health and HIV topics. In multivariable analysis, African migrants who were students (adjusted odds ratio (aOR) = 3.36, 95% CI = 2.40-4.71), living in student dormitories (aOR = 3.86, 95% CI = 1.51-9.84), received health services in China in past year (aOR = 1.67, 95% CI = 1.25-2.23), had lifetime sexually transmitted infections (STI) testing (aOR = 1.95, 95% CI = 1.23-3.10), had HIV testing before coming to China (aOR = 13.56, 95% CI = 9.36-19.65), and those engaged in community discussions of HIV and sexual health (aOR = 2.77, 95% CI = 1.31-5.83) were more likely to test for HIV in China. Conclusions: Despite 73% of African migrants having tested for HIV in China, there are unmet needs and barriers identified in our study, such as language barriers. Access to HIV knowledge and testing services were the most important enablers for testing, including studentship, past STI/HIV testing, and community discussion on sexual health. Culturally appropriate and community-based outreach programs to provide information on HIV and testing venues for African migrants might be helpful to promote testing uptake.
