Background: During the COVID-19 pandemic Chinese international students were reported to experience racism, food security issues and social isolation. However, no study has investigated the prevalence of these issues and the potential for worsening mental health in this population group during the pandemic. Therefore, this study aimed to examine the effect of this pandemic on the mental health of Chinese international students living in Australia and China, and the protective effect of social support.
Methods: Data were extracted from a survey of Australian university students (April-June 2019) and follow-up during the pandemic (Sept-Oct 2020). The prevalence of anxiety, major depression and pandemic-related stressors was reported. Multivariable logistic regression was used to assess the association between country of residence, social support (baseline/follow-up), and follow-up self-reported mental health.
Results: With the pandemic, there was a substantial increase in the prevalence of anxiety (24.7 % vs 45.7 %) and major depression (22.1 % vs 43.8 %). Major depression was less likely to be reported by international students in China (34.8 %) than in Australia (46.3 %). Students with high social support during the pandemic were less likely to report major depression (Adjusted OR:0.15 [95 % CI 0.06,0.34]), although this effect was not observed longitudinally (Adjusted OR:1.03 [95 % CI 0.58,1.83]).
Limitation: Post pandemic improvement in mental health cannot be assessed.
Conclusion: The pandemic appeared to have had a strong negative effect on Chinese international university students' mental health. Those living in Australia were more likely to experience poorer mental health, highlighting the need for increased support to this group.
