Post-migration well-being of Sub-Saharan Africans in China: a nationwide cross-sectional survey.

Purpose This study aims to understand the quality of life (QOL) among Sub-Saharan African (SSA) migrants and explore the factors that contribute to and shape SSA migrants' QOL and shed light on how post-migration factors affect their QOL in China. Methods We conducted a nationwide cross-sectional survey on QOL of SSA migrants in China from August, 2019 to November, 2019. We recruited SSA migrants using a combination of peer-referred online and offline surveys. The WHOQOL-BREF scale assessed the QOL of participants, and depressive symptoms were measured using Center for Epidemiologic Studies-Depression scale. Correlates of well-being including depressive symptoms, migration-related factors, and socio-demographic characteristics were included in hierarchical linear regression models to explore the contributions of these factors on QOL of SSA migrants. Results This study included 928 eligible SSA migrants. The total score of the WHOQOL-BREF scale was 66.8 ± 14.0. Attitudes of local people toward SSA migrants (β = 3.1, 95% CI 2.4, 3.0) and satisfaction with their living conditions (β = 3.6, 95% CI 2.5, 4.7) were positively associated with QOL and explained 12.2% of the variance. Contracting an infectious disease in the past year (β = - 5.3, 95% CI - 7.6, - 2.9) and depression werenegatively associated with QOL (β = - 0.7, 95% CI - 0.7, - 0.6) and explained 24.4% of the variance. Conclusion Our study underscores the importance of several key factors that may aid in the improvement of QOL among SSA migrants. Post-migration environmental factors emerged as key correlates of QOL, which builds on previous evidence that the post-migration context should be improved to safeguard the well-being of SSA migrants in China.
