Young people, pregnant and postpartum people, and those who were hospitalised with COVID-19 appear to be the most impacted, according to the research published in Frontiers in Psychiatry today.
Led by the University of Sydney’s Matilda Centre for Research in Mental Health and Substance Use, in collaboration with the Australian National University’s Centre for Mental Health Research, the review drew conclusions from screening over 6000 individual pieces of research.
Professor Maree Teesson said while many want to believe we’re “back to normal” in Australia, the statistics show heightened levels of mental ill health that are hard to ignore.
What worries me is that rather than having an intense recovery phase in Australia we’ve had further crises, including marked increases in costs of living and natural disasters, all of which we know exacerbate mental health problems.
“If we don’t act to implement holistic strategies now, particularly for young people, we risk having a whole generation at a long-term disadvantage,” said co-lead author and University of Sydney PhD student Scarlett Smout.
The umbrella review is the first to assess the wide range of international mental health research conducted during the pandemic to untangle the longitudinal mental health impact. Following this, the researchers also collated the results from high-quality studies and used statistical methods (a meta-meta analysis) to identify overall effects.
Research fellow and co-lead author Dr Marlee Bower, also of the Matilda Centre, said: “Using the most rigorous methods and including only the highest quality evidence, our review is the first-of-its-kind to paint an accurate and holistic picture of current science on the mental health impacts of COVID-19."
In May 2022 Australia’s Mental Health Think Tank released the Youth Recovery Plan, which makes actionable recommendations on how to remediate the mental health impacts of COVID and other crises on young people.
It includes evidence-based recommendations to address the three key drivers of poor youth mental health: financial stress, disconnection and lack of access to mental healthcare.
However, senior author of the new review and Chair of the Think Tank Professor Maree Teesson said minimal progress has been made by governments in these areas.
Notably one of the Plan’s recommendations has been enacted in part: the Australian Government has increased the number of Commonwealth supported places for degrees in mental health related professions.
“However, there have been no meaningful changes to income support schemes such as youth allowance and jobseeker, aside from a $1.77 per day increase to keep up with inflation, despite skyrocketing costs of living,” said Professor Teesson.
The authors hope the new review will focus ongoing attention and investment in the mental health of groups that need it the most, echoing the World Psychiatric Association’s call for continued funding for mental health services despite COVID-19 related strains on global government budgets.
The researchers acknowledge some limitations to the review including considerable variability in findings from included research, meaning the estimates provided by the meta-meta-analysis have some degree of uncertainty. Authors highlight the pervasiveness of poor-quality research, identified through a gold standard appraisal process. While they were able to account for this in the analysis, they emphasise the need for greater quality control in mental health research moving forward.
They also suggest more research is needed into sub-groups likely affected by restrictions and lockdowns such as children and people experiencing housing issues, as well as into the impact of vaccination on mental health.
