The mental health of international university students from China during the COVID-19 pandemic and the protective effect of social support: A longitudinal study.

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.

Inclusion of Cultural and Linguistic Diversity in COVID-19 Public Health Research: Research Design Adaptations to Seek Different Perspectives in Victoria, Australia.

Participation of people from culturally and linguistically diverse (CALD) communities in public health research is often limited by challenges with recruitment, retention and second-language data collection. Consequently, people from CALD communities are at risk of their needs being marginalised in public health interventions. This paper presents intrinsic case analyses of two studies which were adapted to increase the cultural competence of research processes. Both cases were part of the Optimise study, a major mixed methods research study in Australia which provided evidence to inform the Victorian state government's decision-making about COVID-19 public health measures. Case study 1 involved the core Optimise longitudinal cohort study and Case study 2 was the CARE Victorian representative survey, an Optimise sub-study. Both case studies engaged cultural advisors and bilingual staff to adjust the survey measures and research processes to suit target CALD communities. Reflexive processes provided insights into the strengths and weaknesses of the inclusive strategies. Selected survey results are provided, demonstrating variation across CALD communities and in comparison to participants who reported speaking English at home. While in most cases a gradient of disadvantage was evident for CALD communities, some patterns were unexpected. The case studies demonstrate the challenge and value of investing in culturally competent research processes to ensure research guiding policy captures a spectrum of experiences and perspectives.
