Australians\u2019 life expectancy has increased steadily over time but dropped during the COVID pandemic, according to a new report released today by the Australian Institute of Health and Welfare<\/a>.<\/p>\n

The report \u2013 Australia\u2019s Health 2026<\/a> \u2013 shows life expectancy for a boy born in 2022\u20132024 was 81.1 years, while a girl could expect to live, on average, to 85.1 years.<\/p>\n<\/p>\n

However newer data not included in the report shows this has stabilised and life expectancy in 2024 was up marginally at 85.5 for women and 81.6 for men. <\/p>\n

Between 2003 and 2024, Australians\u2019 life expectancy and years lived in \u201cfull health\u201d increased. But the time spent in poor health also rose: by 1.2 years for men and 1.5 years for women. <\/p>\n

\n Australians live longer than previous decades but spend more years in poorer health<\/a><\/p>\n

More than three in five (61%) Australians now have at least one chronic condition \u2013 such as asthma, arthritis or depression \u2013 and almost two in five (38%) have two or more. <\/p>\n<\/p>\n

Cancer causes the most burden of disease, or years of healthy life lost to illness and premature death. Mental conditions and substance use disorders as a group are the second biggest cause of healthy life lost.<\/p>\n<\/p>\n

Dementia is now the leading cause of death in Australia, accounting for almost one in ten deaths in 2024. Dementia deaths rose by 39% in a decade, while deaths from coronary heart disease \u2013 the previous leading cause of death \u2013 decreased by 18%. <\/p>\n<\/p>\n

So what are the biggest changes to Australia\u2019s health and wellbeing over the past two years? The Conversation\u2019s panel of health experts explain.<\/p>\n

Mental illness is rising among young people but supports aren\u2019t keeping up<\/p>\n

\"Sebastian<\/p>\n

\nSebastian RosenbergAssociate Professor, Brain and Mind Centre, University of Sydney\n<\/p>\n

One in five Australians aged 16\u201385 (22%) had experienced a mental disorder in the previous 12 months. This rate appears fairly stable<\/a>.<\/p>\n

However, the proportion of people aged 16\u201324 experiencing a mental disorder has increased, from 26% to 39% between 2007 and 2020\u20132022. <\/p>\n

Given 75% of all mental illness manifests before the age of 25<\/a>, we need effective responses<\/a> for young Australians. <\/p>\n

Mental illness is 15% of the total burden of disease and suicide. Meanwhile, self-inflicted injury was the leading cause of disease burden among males aged 15\u201344. <\/p>\n

Yet a previous report found mental health accounts for only 7%<\/a> of total health spending. This gap doesn\u2019t explain all of the crisis in mental health, but it explains something.<\/p>\n

Some 6.5% of Australians are reported as having psychosocial disability (disability arising from a mental illness). This is up from 4.6% in 2018. <\/p>\n<\/p>\n

Now half a million Australians<\/a> with severe or moderate psychosocial support needs aren\u2019t receiving<\/a> support through the National Disability Insurance Scheme (NDIS) or other government\u2010funded programs. <\/p>\n

More cancer in young people but survival rates are increasing overall<\/p>\n

\"Sarah<\/p>\n

\nSarah DiepstratenSenior Research Officer, Blood Cells and Blood Cancer Division, Walter and Eliza Hall Institute of Medical Research\n<\/p>\n

Significantly more Australians are surviving five years after a cancer diagnosis, up from 50% in 1987\u20131991 to 72% in 2017\u20132021. <\/p>\n

This is due to people being diagnosed earlier, when cancers are easier to treat, as well as the availability of more effective therapies. <\/p>\n

While survival rates have not improved for all cancers equally, even the deadliest cancers have seen major improvements. Pancreatic cancer only has a 14% five-year survival rate<\/a> (2017\u20132021), but this has increased from only 3.1%<\/a> (1987\u20131991). <\/p>\n

The report highlights increasing cancer incidence among younger people. Diagnoses for people in their 30s have risen by 11.6% since 2000<\/a>, primarily for colorectal and thyroid cancers. <\/p>\n

But the actual numbers remain low (135 cases per 100,000 people), and the number of deaths from cancer among younger people has actually declined by 38% since 2000<\/a>.<\/p>\n

While cancer remains the greatest contributor to disease burden in Australia, addressing modifiable risk factors such as obesity and smoking \u2013 coupled with cancer screening and focused research initiatives \u2013 will help reduce cancer incidence and deaths going forward.<\/p>\n

Obesity has overtaken smoking as the leading contributor to disease<\/p>\n

\"Kathryn<\/p>\n

\nKathryn BackholerCo-Director, Global Centre for Preventive Health and Nutrition, Deakin University\n<\/p>\n

Excess weight and obesity have overtaken tobacco use as the leading risk factor contributing to disease burden. <\/p>\n

In 2022\u201324, around 13.2 million adults (67%) and 1.4 million children and adolescents (27%) were living with obesity or were overweight. <\/p>\n

The generational pattern is particularly concerning. Australians born more recently are more likely to be living with obesity compared to previous generations at the same age. Among adults aged 25\u201334, obesity increased from 20% in 2011\u201312 to 29% in 2022\u201324. <\/p>\n

Urgent action is needed to create healthier environments that make it easier for Australians to choose healthy foods and stay physically active.<\/p>\n

We also need more equitable access to evidence-based treatment and care, including GLP-1 weight-loss medicines. As the report notes, the high cost of these medicines means the people with the greatest need are often less able to access them. <\/p>\n

Risky drinking is down, but we still drink more than our OECD peers<\/p>\n

\"Nicole<\/p>\n

\nNicole LeeAdjunct Professor at the National Drug Research Institute, Curtin University\n<\/p>\n

Australians drink 9.8 litres of pure alcohol (773 standard drinks) per person each year. This is well above the OECD average of 8.4 litres.<\/p>\n

First Nations people are less likely to drink at all than the general population and risky drinking among in First Nations people has fallen from 48% in 2010 to 33% in 2022-23.<\/p>\n

Risky drinking, which is often linked to injuries and emergency department visits, has also declined<\/a> in the general population. <\/p>\n

But alcohol is now one of the most preventable drivers of chronic disease. It contributes to more than 200<\/a> health conditions such as cancer, heart and liver disease, injuries and poor mental health.<\/p>\n

With Australia\u2019s population ageing \u2013 and three in five Australians already living with at least one chronic condition \u2013 reducing risky drinking is one of our biggest opportunities to prevent future disease and ease pressure on the health system.<\/p>\n

Health-care costs have risen, with more people skipping care<\/p>\n

\"Peter<\/p>\n

\nPeter BreadonProgram Director, Health and Aged Care, Grattan Institute\n<\/p>\n

After pandemic fluctuations, three long-term trends resumed: government spending kept going up, so did the share of funding going to hospitals, and so did patient out-of-pocket fees.<\/p>\n

Australia spent just over $10,000 per person on health in 2023\u201324. That\u2019s 17% higher than a decade ago, on top of inflation, and a quarter higher than the average among wealthy nations.<\/p>\n

The biggest area of health spending remains hospitals, which take up a growing share, rising from 39% to 42% over the past decade.<\/p>\n

Average out-of-pocket fees totalled $1,634, nearly $200 more than a decade earlier (in today\u2019s dollars). As fees go up, more people are skipping care, with 8% of Australians saying they delayed or avoided a GP visit in 2024\u201325 because of the cost.<\/p>\n

And for some care, patients shoulder a much bigger share of the bill. They pay the most for dental care, covering 61% of total costs, so it\u2019s no surprise 16% of people skipped dental care due to cost.<\/p>\n

Carers are compensating for system gaps and are burnt out<\/p>\n

\"Helen<\/p>\n

\nHelen DickinsonProfessor, Public Service Research, UNSW Sydney<\/p>\n

Unpaid carers provide ongoing support to family members, friends and neighbours who have a disability, chronic illness, mental illness, age-related frailty, dementia, or other condition that limits their independence. <\/p>\n

In 2022 around 3 million<\/a> Australians (one in eight) provided informal care, including 1.2 million primary carers. These carers perform a wide range of tasks that help the person remain safe, healthy and living in the community.<\/p>\n

Unpaid carers are estimated to save the Australian economy around $77.9 billion each year<\/a> in avoided care costs. <\/p>\n

Research consistently shows carers experience poorer health and wellbeing than the general population. The AIHW report shows:<\/p>\n

61% of carers did not report healthy levels of wellbeing, compared with 34% of Australians overall<\/p>\n

43% felt lonely (often or always) compared with 12% of Australians overall<\/p>\n

36% experienced high psychological distress, compared to 16% of Australians overall.<\/p>\n

The report warns that:<\/p>\n

without better-coordinated and more responsive formal support, pressures on unpaid carers may intensify. <\/p>\n

Yet the federal government\u2019s proposed NDIS reforms<\/a> may increase pressures on unpaid carers by tightening eligibility and reducing funded supports<\/a>. <\/p>\n

This risks shifting greater caring responsibilities onto families. <\/p>\n
