Obesity in Australia has been described as an epidemic with increasing frequency. In 2022, almost two-thirds (65.8%) of adults were overweight or obese, with 31.7% falling into the obese category. This is a notable increase from 1995, when 30% of adults were overweight and 11% were obese. The prevalence of obesity is higher among men (32.5%) than women (30.9%), and is also higher among Indigenous Australians (31%) than the general population.

What You'll Learn
Obesity in Australia is an epidemic
The rise in obesity has been attributed to several factors, including poor eating habits, the availability of fast food, sedentary lifestyles, and a decrease in the labour workforce. The adoption of a Western diet and a more sedentary lifestyle has also been linked to higher rates of obesity among first-generation immigrants to Australia, particularly Asians, Pacific Islanders, and Middle Eastern refugees.
Recent studies indicate that the prevalence of overweight and obese adults in Australia continues to rise. In 2022, two-thirds of Australian adults were classified as overweight (34%) or obese, with men having higher rates than women. This represents an increase from previous years, with the proportion of obese adults rising from 27.5% in 2011-12 to 31.7% in 2022.
Indigenous Australians have the highest level of obesity in the country. A 2001 study found that 31% of Aboriginal Australians and Torres Strait Islanders were obese, nearly double the national average at that time. More recent data from 2018-19 shows that 45% of First Nations people aged 18 and over were living with obesity, and they were 1.5 times more likely to be obese than non-Indigenous adults.
The high rates of obesity in Australia have significant implications for public health. Obesity is a risk factor for various chronic conditions and is associated with higher rates of death. The National Preventive Health Strategy 2021-2030 and the National Obesity Strategy 2022-2032 have been implemented to address this issue, aiming to prevent, reduce, and treat overweight and obesity in the country.

Obesity among Indigenous Australians
According to the latest data, 38% of Indigenous Australian children and adolescents aged 2-17 are living with overweight or obesity. This is an increase from the 31% estimated from the previous Australian Aboriginal and Torres Strait Islander Health Survey in 2012-13. In 2018-19, the proportion of First Nations boys living with overweight or obesity increased with age, from 21% of those aged 2-4 years to 33% of those aged 5-9 and 45% of those aged 10-14. For girls, there was no significant difference in the proportion living with overweight or obesity across age groups.
Indigenous Australians have the country's highest level of obesity. A 2001 study found that 31% of Aboriginal Australians and Torres Strait Islanders were obese, nearly double the national average at that time. In 2018-19, Indigenous Australians aged 15 and over were 1.5 times more likely to be obese than non-Indigenous Australians. The overweight and obesity rate was highest in inner regional areas (76%) and lowest in very remote areas (62%).
The high prevalence of overweight and obesity among Indigenous Australians has significant implications for the public health system. Obesity is a leading risk factor for preventable chronic conditions such as heart disease, certain cancers, and type 2 diabetes. It is associated with a significant reduction in life expectancy.
Community-led initiatives have been effective in promoting healthy lifestyles among Indigenous Australians. For example, the 'Knockout Health Challenge' in New South Wales successfully encouraged participants to increase their physical activity and fruit and vegetable consumption. However, men were less likely to participate in such programs than women, suggesting that further research is needed to engage men in healthy lifestyle interventions.
Overall, the prevalence of overweight and obesity in Australia has been increasing over the years, with nearly two-thirds of Australian adults falling into these categories in 2022-23. The rise in obesity has been attributed to various factors, including poor eating habits, the availability of fast food, sedentary lifestyles, and geographical factors such as living in regional towns and remote regions.

Obesity in children and adolescents
Obesity is a significant health issue in Australia, and this extends to children and adolescents. In 2022-23, around one in four (25%) Australian children and adolescents aged 2-17 were overweight or obese, with 18.3% classified as overweight and 8.1% as obese. This represents a slight increase from 2017-18, when 25% of children and adolescents were overweight or obese, and 8.2% were obese.
The prevalence of overweight and obesity in Australian children and adolescents varies across the country. In 2017-18, Tasmania had the highest rate of obesity (11.4%), while Western Australia had the lowest (7.2%). In 2022-23, the prevalence of overweight and obesity was higher in regional and remote areas than in major cities. Additionally, certain demographic groups are more likely to be overweight or obese. For example, Indigenous children and adolescents have higher rates, increasing from 31% in 2012-13 to 38% in 2018-19. Similarly, children living in disadvantaged areas are more likely to be overweight or obese.
The increase in overweight and obesity rates among children and adolescents in Australia has been attributed to various factors. One factor is the adoption of a Western diet and sedentary lifestyle, particularly among first-generation immigrants. A study found that Asians, Pacific Islanders, and Middle Eastern immigrants in Australia were diagnosed with diabetes at a higher rate than the average due to the adoption of less healthy diets and more sedentary lifestyles. Additionally, the availability of fast food, the popularity of sedentary lifestyles, and a decrease in the labour workforce have contributed to the rise in obesity rates across the country.
The high prevalence of overweight and obesity in Australian children and adolescents has significant implications for their health and wellbeing, school performance, and future health risks. It is also associated with higher healthcare costs. As a result, addressing overweight and obesity in this age group is a crucial priority for policymakers aiming to improve the overall health of the population.

Obesity rates in regional and rural areas
Obesity is a growing problem in Australia, with the rate of obesity among adults increasing from 24.4% to 31.1% in recent years. The country has the third-highest prevalence of overweight adults in the English-speaking world, and obesity has been described as an "epidemic" in Australia.
While there is limited data on obesity rates in small geographic areas, some studies have found that the prevalence of adult obesity is higher in regional and rural areas compared to major cities. One study reported that the prevalence of obesity in regional city urban areas was 22-32% and 24-32% in regional city rural areas, while another study found that 22% of respondents lived in regional city rural areas, the second-highest proportion after major city urban areas (65%). These findings support the hypothesis that geographic disparity persists in the prevalence of adult obesity in Australia.
However, one study focusing on rural areas in Victoria found a decline in obesity prevalence among rural dwellers over 15 years. The study hypothesized that this could be due to better access to fresh produce and fewer takeaway options in smaller, rural towns. The lifestyle and type of jobs in rural areas, such as farming and manual labor, may also contribute to the lower obesity rates.
Indigenous Australians have the highest level of obesity in the country, with a 2001 study showing that 31% of Aboriginal Australians and Torres Strait Islanders were obese, nearly double the national average at that time. Additionally, first-generation immigrants to Australia have higher rates of obesity and obesity-related behaviors than white Australians or Australians of foreign ancestry whose families have been in the country for at least two generations.
Overall, the prevalence of overweight and obesity in Australia is a significant issue, and public health measures should focus on contextual obesogenic factors and behavioral characteristics to curb the rising prevalence of obesity, especially in regional and rural areas.

Obesity and gender differences
Obesity is a significant health issue in Australia, with the country experiencing an epidemic of obesity, according to the Medical Journal of Australia. The prevalence of obesity among Australian adults has been steadily rising over the past decade. In 2022, two-thirds of Australian adults were living with overweight or obesity, with 34% classified as overweight and 31.7% as obese.
When it comes to gender differences, there are some notable variations in obesity rates between men and women in Australia. Overall, men have a higher prevalence of overweight and obesity than women. In 2022-23, around seven in ten (71.2%) Australian men were living with overweight or obesity, compared to 60.5% of women. However, when it comes to obesity specifically, the proportions are similar between men (32.5%) and women (30.9%).
The gender differences in obesity rates are influenced by various factors, including demographic, economic, social, and personality traits. A study found that age and personality traits, such as openness, were significant factors for females but not for males. In contrast, factors like the area of residence, meals eaten out, disposable income, and extroversion were more significant for males than females. These differences highlight the need for gender-specific preventive health measures and policies to address the obesity epidemic effectively.
Indigenous Australians, including Aboriginal and Torres Strait Islander adults and children, have significantly higher obesity rates than the general population. Additionally, first-generation immigrants to Australia, particularly from Asian, Pacific Islander, and Middle Eastern backgrounds, have higher rates of obesity and obesity-related behaviours than white Australians or those with longer ancestries in the country. These disparities may be attributed to the adoption of Western diets and more sedentary lifestyles upon migration.
Obesity rates also vary across different geographical areas in Australia, with regional cities and rural areas having higher obesity prevalence than major cities. Socioeconomic status also plays a role, with individuals from lower socioeconomic backgrounds having higher rates of overweight and obesity than those from higher socioeconomic areas. These variations underscore the complexity of the obesity issue in Australia and the need for tailored interventions to address these disparities effectively.
