Changes in mental health across the COVID-19 pandemic for local and international university students in Australia: a cohort study.

PURPOSE: Previous research has indicated that university students experienced substantial mental health issues during the global COVID-19 pandemic, but few studies have considered changes relative to pre-pandemic levels across population groups. Hence, the aim of this study was to compare changes in mental health and associated stressors across the pandemic for international and local university students studying in Australia. METHODS: In a cohort of 4407 university students, we assessed depression (Patient Health Questionnaire 2), anxiety (Generalized Anxiety Disorder-2), social support (Medical Outcomes Study-Social Support Survey), inability to afford food, fear of partner, and experiences of discrimination, both pre-pandemic (April-May 2019) and during the pandemic (September-October 2020). Change in prevalence between local and international students were estimated with logistic regression, adjusting for baseline factors. RESULTS: Compared to local students, international students experienced an increase in probable major depression (odds ratio (OR) 1.43, 95% Confidence Interval (CI) 1.23, 1.66), low social support (OR 2.63, 95% CI 2.23, 3.11), inability to afford food (OR 5.21, 95% CI 3.97, 6.83) race-based discrimination (OR 2.21, 95% CI 1.82, 2.68) and fear of partner (OR 3.46, 95% CI 2.26, 5.13). Interaction analyses indicated that these issues were more likely to be experienced by students living outside their country of origin, inclusive of international students based in Australia (depression p value interaction term 0.02). CONCLUSION: The pandemic had a substantial negative impact on international students, particularly those living outside of their country of origin during the pandemic. The inequalities exacerbated by the pandemic were present prior to the pandemic and are likely to continue post-pandemic without action. Interventions to build the supports for international students need to be urgently explored.

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.

Towards a health promoting university: descriptive findings on health, wellbeing and academic performance amongst university students in Australia.

BACKGROUND: Universities are increasingly recognised as institutions where health and wellbeing can be promoted to maximise academic outcomes, career transitions, and lifelong positive health behaviours. There is concern about the mental health of university students and other factors which affect academic outcomes particularly for subgroups such as international students. There are few cohort studies of the breadth of issues that can impact on mental health and academic outcomes for both local and international students. We conducted a baseline prevalence survey of students at a large Australian university covering health, academic, and social determinants of wellbeing. The purpose was to inform the university's new student health and wellbeing framework with a view to follow-up to determine predictors of mental ill-health and academic outcomes in the subsequent year. In this paper we present the baseline prevalence data and report on selected mental health and health care access issues for local and international students. METHODS: The entire university population as of April 2019 of over 56,375 students aged 18 or above were invited to complete the online survey. Questions explored eight domains: demographic characteristics, general health and wellbeing, mental health, risk taking behaviours, psychosocial stressors, learning and academic factors, social and cultural environment, and awareness of and access to health and wellbeing services. Records of academic results were also accessed and matched with survey data for a large subset of students providing consent. RESULTS: Fourteen thousand eight hundred eighty (26.4%) students commenced our survey and were representative of the entire student population on demographic characteristics. Three quarters were aged between 18 to 25 years and one third were international students. Eighty-five percent consented to access of their academic records. Similar proportions of local and international students experienced symptoms of a depression or anxiety disorder, however international students were less aware of and less likely to access available health services both inside and external to the university. We also reported on the prevalence of: general lifestyle factors (diet, exercise, amount of daily sleep); risk-taking behaviours (including alcohol, tobacco and other drug use; unprotected sexual activity); psychosocial stressors (financial, intimate partner violence, discrimination, academic stressors, acculturative stress); subjects failed; resilience; social supports; social media use; and health services accessed online. CONCLUSIONS: This rigorous and comprehensive examination of the health status of local and international students in an Australian university student population establishes the prevalence of mental health issues and other psychosocial determinants of health and wellbeing, along with academic performance. This study will inform a university-wide student wellbeing framework to guide health and wellbeing promotion and is a baseline for a 12-month follow-up of the cohort in 2020 during the COVID-19 pandemic.

Is asthma associated with COVID-19 infection? A UK Biobank analysis.

BACKGROUND: The relationship between asthma and coronavirus disease 2019 (COVID-19) risk is not clear and may be influenced by level of airway obstruction, asthma medication and known COVID-19 risk factors. We aimed to investigate COVID-19 risk in people with asthma. METHODS: We used UK Biobank data from all participants tested for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (n=107 412; 17 979 test positive). Questions at baseline defined ever asthma and asthma medications. Baseline forced expiratory volume in 1 s (FEV1) was categorised into quartiles. Logistic regression modelled relationships between asthma, and asthma categories (age at onset, medications, FEV1 quartiles), and risk of SARS-CoV-2 positive test. We investigated modification by sex, ethnic group, smoking and body mass index. RESULTS: There was a reduced risk of a positive test associated with early-onset asthma (<13 years) (OR 0.91, 95% CI 0.84-0.99). This was found for participants with early-onset asthma who were male (OR 0.87, 95% CI 0.78-0.98), nonsmokers (OR 0.87, 95% CI 0.78-0.98), overweight/obese (OR 0.85, 95% CI 0.77-0.93) and non-Black (OR 0.90, 95% CI 0.82-0.98). There was increased risk amongst early-onset individuals with asthma in the highest compared to lowest quartile of lung function (1.44, 1.05-1.72). CONCLUSION: Amongst male, nonsmoking, overweight/obese and non-Black participants, having early-onset asthma was associated with lower risk of a SARS-CoV-2 positive test. We found no evidence of a protective effect from asthma medication. Individuals with early-onset asthma of normal weight and with better lung function may have lifestyle differences placing them at higher risk. Further research is needed to elucidate the contribution of asthma pathophysiology and different health-related behaviour, across population groups, to the observed risks.
