4 September 2014 - The Australian Self Medication Industry (ASMI) said estimates of the number of Australians living with osteoporosis highlights the importance of preventing this chronic disease.

In its report, Estimating the Prevalence of Osteoporosis in Australia,1 the Australian Institute of Health and Welfare (AIHW) said that it is difficult to accurately estimate the true prevalence of osteoporosis in the community because it has no obvious symptoms and many cases are not diagnosed until a minimal trauma fracture occurs. While several epidemiological studies have attempted to provide definitive prevalence estimates of osteoporosis in Australia, estimates vary according to the methodology of the study and a variety of other factors.

The Australian Health Survey (2011-12) reported that the prevalence of self-reported diagnosed osteoporosis amongst those aged 50 and over living in the community was 15% of women and 3% of men. 2 However, a study which measured bone density in a population sample revealed that the prevalence of osteoporosis among those aged 50 and over was 23% of women and 6% of men. This estimate includes both diagnosed and undiagnosed cases of osteoporosis. 3

Steve Scarff, ASMI Director Regulatory and Scientific Affairs said: "Osteoporosis is a disease in which the density and quality of bone are reduced, leading to weakness of the skeleton. The condition increases the risk of fracture, particularly at the hip, spine and wrist. With a growing number of Australians reaching retirement age, osteoporosis is expected to grow in prevalence.4

"Calcium is an essential mineral that is stored in the bones of the human body. It is not only required for the normal development and maintenance of the skeleton, but also to ensure optimal operation of neuromuscular and cardiac functions.5

"While the required intake of calcium is typically met through the consumption of calcium rich foods such as dairy products, nuts and fish, the absorption and metabolism of this mineral is dependent on vitamin D. Sufficient vitamin D intake is particularly important in low light conditions, as the body's ability to synthesise the compound is dependent on exposure to ultraviolet light.

"Nearly a quarter of Australians have a vitamin D deficiency. The 2011-13 Australian Health Survey (AHS) found that 17% of people had a mild deficiency, 6% a moderate deficiency and less than 1% a severe deficiency. Vitamin D deficiency was much lower in those who took a supplement. 6

"The Australian Health Survey found that one in twenty people used a vitamin D supplement. For people who aren't obtaining adequate vitamin D from natural sources such as sunlight, supplementation is a highly effective way to fill the gap.

"Australians who are unsure about their calcium and vitamin D intake are encouraged to talk to a qualified healthcare professional who can provide advice on ways to monitor and if needed, increase their calcium and vitamin D levels," said Mr Scarff.
