Osteoporosis is a common disease in Australia, affecting over a million Australians aged 50 and over. It is a condition that causes bones to become thin, weak, and fragile, increasing the risk of fractures, especially in the hip, wrist, and spine. The prevalence of osteoporosis in Australia varies across different population segments, with a higher prevalence among women compared to men and an increase in prevalence with advancing age. While the rate of minimal trauma hip fractures has decreased over the last decade, the number of hip fractures continues to rise due to the growing older adult population in Australia.

What You'll Learn
Prevalence: ~853,600 or 3.4% of Australians
Osteoporosis is a common disease in Australia, with an estimated 853,600 people or 3.4% of the population living with the condition. It is a condition that causes bones to become thin, weak, and fragile, leading to an increased risk of fractures. The true prevalence of osteoporosis in Australia is likely higher than estimated, as many cases go undiagnosed due to the condition having no obvious symptoms until a fracture occurs, earning it the nickname ""silent disease".
The prevalence of osteoporosis varies across different demographic groups in Australia. According to the 2022 National Health Survey, osteoporosis was more prevalent among women (5.5%) than men (1.1%). Additionally, the prevalence increased with age, affecting 0.7% of people aged 35-44 and reaching 17% in those aged 75 and above. By 2022, it is projected that approximately 6.2 million Australians over 50 years of age will suffer from poor bone health, either osteoporosis or osteopenia.
Osteoporosis is one of the risk factors for minimal trauma fractures, which can have serious consequences. The hip is one of the most common sites for fractures, and a fracture in this area can be life-threatening. While the rate of minimal trauma hip fractures has decreased over the last decade, the number of hip fractures continues to rise due to the aging population in Australia.
The impact of osteoporosis extends beyond the physical health of individuals. The condition imposes a significant health burden, with associated costs for hospitalisations, emergency services, rehabilitation, and aged care. By 2022, the projected total cost of poor bone health among Australians aged 50 and over is estimated to reach $3.84 billion. Therefore, early diagnosis and management of osteoporosis are crucial to reducing the disease burden and preventing osteoporotic fractures.

Sex: More prevalent in women
Osteoporosis is a common disease in Australia, with an estimated 1.2 million people suffering from it. It is a condition that causes bones to become thin, weak, and fragile, making them susceptible to fractures from even minor bumps or accidents. While it can affect any bone, the hip, spine, and wrist are common fracture sites.
Osteoporosis is more prevalent in women than in men. In 2022, the prevalence of osteoporosis was estimated to be 5.5% among women and 1.1% among men. This disparity is further highlighted in the older population, with 29% of women and 10% of men aged 75 and over having osteoporosis in 2017-18.
The Australian Health Survey from 2011-12 revealed that among those aged 50 and over, 15% of women and 3% of men self-reported a diagnosis of osteoporosis. However, when considering both diagnosed and undiagnosed cases, the prevalence was estimated to be higher, with 23% of women and 6% of men affected.
The higher prevalence of osteoporosis in women is also evident in the rates of minimal trauma hip fractures, a serious outcome of the condition. In 2011-12, 72% of hospitalisations for minimal trauma hip fractures in those aged 50 and over were women. While the rate of these fractures has decreased over time, the absolute number continues to rise due to Australia's aging population.
The reasons for the higher prevalence of osteoporosis in women are not entirely clear, but it may be due to various factors, including hormonal differences, bone structure, and peak bone mass achieved during growth. Regardless, the condition significantly impacts the health and well-being of a substantial number of Australian women.

Age: More prevalent in older people
Osteoporosis is a common disease in Australia, with an estimated 1.2 million people suffering from it. It is a condition that causes bones to become thin, weak, and fragile, increasing the risk of fractures. The prevalence of osteoporosis increases substantially with age, affecting older people more severely.
In 2022, the prevalence of osteoporosis was estimated to be 0.7% among individuals aged 35-44, while for those aged 75 and above, it rose to 17%. This indicates a significant rise in osteoporosis cases with advancing age. The Australian Health Survey from 2011-12 further supports this trend, reporting that among those aged 50 and above, 15% of women and 3% of men had self-reported diagnosed osteoporosis.
The impact of osteoporosis on older adults is profound. It is often referred to as a "'silent disease'" because it frequently goes undiagnosed until a fracture occurs. Many cases remain undetected, making it challenging to determine the true prevalence of the condition. Osteoporosis-related fractures can lead to chronic pain, loss of independence, disability, and even premature death.
The rate of minimal trauma hip fractures, one of the most serious outcomes of osteoporosis, has decreased over the last decade for those aged 50 and above. However, due to the growing number of older adults in Australia, the absolute number of hip fractures continues to rise. In 2011-12, 19,000 people aged 50 and over were hospitalised due to minimal trauma hip fractures, with 71% belonging to the 80 and above age group.
Osteoporosis disproportionately affects older women. In 2017-18, 29% of women aged 75 and above had osteoporosis, compared to only 10% of men in the same age group. This gender disparity is also evident in the 2011-12 Australian Health Survey, where the prevalence of osteoporosis among women aged 50 and over was estimated to be 23%, significantly higher than the 6% prevalence among men in the same age bracket.

Symptoms: Often asymptomatic until fracture
According to the 2022 Australian Bureau of Statistics National Health Survey, around 853,600 (3.4%) people in Australia live with osteoporosis or osteopenia. The true prevalence, including undiagnosed cases, is likely higher. Osteoporosis is a condition that causes bones to become thin, weak, and fragile, increasing the likelihood of bone fractures.
Osteoporosis is often referred to as a "silent disease" because it often presents no obvious symptoms until a fracture occurs. Many cases go undiagnosed until a minor bump or accident causes a broken bone. As a result, it is challenging to determine the condition's true prevalence. Healthcare providers emphasize the importance of early diagnosis to reduce the risk of bone fractures. Regular check-ups and bone density tests are recommended, especially for individuals over 65 or with risk factors such as a family history of osteoporosis.
The prevalence of osteoporosis increases with age, affecting older adults in Australia more frequently. In 2011-12, approximately 19,000 individuals aged 50 and above were hospitalized due to minimal trauma hip fractures, with 72% being women. While the rate of hip fractures has decreased over time, the number of fractures continues to rise due to the growing older adult population. Osteoporosis is more prevalent in women, with estimates suggesting that half of women over 50 are affected, compared to one in four men.
To prevent osteoporosis and maintain bone health, it is crucial to ensure adequate calcium intake, either through food sources or supplements. Additionally, quitting smoking can help reduce bone loss and lower the risk of complications after fractures. By taking proactive steps and seeking medical advice, individuals can protect their bone health and reduce the likelihood of osteoporosis-related fractures.

Treatment: Medication, calcium, vitamin D, exercise
According to the 2022 Australian Bureau of Statistics National Health Survey, around 853,600 (3.4%) people in Australia live with osteoporosis or osteopenia. The true number is likely higher when accounting for undiagnosed cases.
Treatment: Medication, Calcium, Vitamin D, and Exercise
Osteoporosis is a condition that causes bones to become thin, weak, and fragile, increasing the risk of fractures. Treatment aims to strengthen bones and prevent fractures. Here are some detailed methods:
Medication:
Pharmacologic treatments can improve bone mass and reduce fracture risk. Treatment guidelines help clinicians decide which patients require medication. For example, postmenopausal women and men over 50 with low bone mass may be recommended medication.
Calcium:
Calcium is essential for bone health and maintenance. It is critical to continue calcium supplementation for patients with bone loss. The recommended daily dose for effective osteoporosis treatment is 1200 mg of calcium.
Vitamin D:
Vitamin D is also crucial for bone health. Sun exposure is the primary way our bodies produce vitamin D. Spending 10-20 minutes daily in the sun without sunscreen can help produce vitamin D, but this may vary depending on factors like geographic location and skin pigmentation. Additionally, certain foods like oily fish (salmon, sardines, mackerel), eggs, mushrooms, liver, and fortified foods like margarine, cereals, and orange juice can provide vitamin D. The recommended daily dose for effective osteoporosis treatment is 800 units of vitamin D.
Exercise:
Physical activity is vital for achieving and maintaining peak bone mass, especially during adolescence and young adulthood. Exercise helps prevent bone loss and reduces the risk of falls, which is essential for individuals with osteoporosis.
