World Osteoporosis Day

World Osteoporosis Day is observed every year on 20 October to focus global attention on osteoporosis, a disease that makes bones weak and fragile, and to promote better bone health at all ages. On this day, doctors, hospitals, patient organizations and communities highlight that broken bones after minor falls are not just a normal part of ageing, but often a sign of osteoporosis that can and should be prevented and treated.

History

World Osteoporosis Day was first launched in 1996 by the United Kingdom’s National Osteoporosis Society, with support from the European Commission. Shortly afterwards, the International Osteoporosis Foundation (IOF) took over leadership and developed it into a global awareness campaign. Since then, World Osteoporosis Day has been marked every 20 October, with themes that encourage people to take care of their bones and recognize the serious consequences of osteoporotic fractures.

Over time, the campaign has grown to include events in more than 90 countries. IOF and national societies organize public lectures, free bone health assessments, exercise demonstrations, media campaigns and policy dialogues. The day emphasizes that osteoporosis is common: estimates suggest that around 1 in 3 women and 1 in 5 men over the age of 50 will experience an osteoporotic fracture in their lifetime. These fractures most often affect the spine, hip and wrist.

Osteoporosis is often called a “silent disease” because bone loss occurs gradually and without pain. Many people do not know they have weak bones until a minor fall, bend or lift causes a fracture – for example, a broken wrist after a simple fall on an outstretched hand, or a collapsed vertebra causing sudden back pain and loss of height. A hip fracture in an older person can be life-changing, leading to loss of independence, long-term disability and even increased risk of death in the year following the fracture.

Why it matters

Healthy bones are essential for standing, walking and performing everyday activities. As we age, bone mass naturally decreases, but in osteoporosis this loss becomes excessive and the internal structure of the bone becomes thin and fragile. Factors that increase the risk of osteoporosis include older age, being female (especially after menopause), a family history of fractures, low body weight, lack of physical activity, low calcium intake, vitamin D deficiency, smoking, heavy alcohol use, certain medicines such as long-term steroids, and some medical conditions like rheumatoid arthritis or long-standing thyroid or kidney disease.

Because osteoporosis develops slowly and without clear symptoms, early detection is crucial. Bone mineral density (BMD) tests such as a DEXA scan can detect low bone mass before fractures occur and help doctors decide on treatment. World Osteoporosis Day encourages people at risk – especially postmenopausal women, men over 50 with risk factors, and anyone who has already had a low-trauma fracture – to talk to their doctor about bone health assessments.

Prevention and treatment strategies are well established. Adequate calcium intake through food (such as milk, yoghurt, small fish with bones, leafy green vegetables and fortified foods) or supplements when necessary, combined with sufficient vitamin D (from sunlight exposure and diet or supplements), helps build and maintain bone. Weight-bearing and muscle-strengthening exercises – such as walking, climbing stairs, simple resistance exercises and balance training – stimulate bones and muscles, improve strength and reduce the risk of falls. Avoiding smoking, limiting alcohol and maintaining a healthy body weight are also important.

For people diagnosed with osteoporosis, medicines prescribed by doctors, including bisphosphonates and other bone-strengthening drugs, can reduce fracture risk. Fall-prevention measures, such as removing loose rugs, improving lighting at home, using handrails, wearing shoes with good grip and checking eyesight and blood pressure, further protect older adults from injuries.

Key facts

In Bangladesh

In Bangladesh and many other low- and middle-income countries, osteoporosis often remains underdiagnosed and undertreated. People may attribute back pain, height loss or difficulty walking simply to “getting old” rather than possible bone disease. Access to specialized bone density testing (DEXA scans) may be limited outside major cities, and awareness about osteoporosis is still growing among the general public.

Dietary patterns in some communities may be low in calcium, especially where dairy consumption is limited or where people avoid certain foods for cultural or economic reasons. Vitamin D deficiency can also be common, even in sunny countries, due to limited outdoor activity, cultural clothing practices that limit sun exposure or darker skin which needs more sunlight to produce sufficient vitamin D. Women who have multiple pregnancies, spend most of their time indoors, or are undernourished may be particularly vulnerable to weak bones later in life.

World Osteoporosis Day provides an opportunity in Bangladesh to highlight bone health in outpatient clinics, orthopaedic departments, rheumatology and endocrinology practices, and community health programs. Hospitals and medical societies may organize public seminars, screening camps for older adults, education sessions on nutrition and exercise, and media discussions about preventing fractures. Simple messages encourage families to pay attention when an older relative sustains a fracture after a minor fall, as this may be a sign of underlying osteoporosis that needs evaluation.

At the household level, practical steps include ensuring that older adults receive enough calcium-rich foods when possible, spending some time in safe morning sunlight, doing simple walking or home-based exercises suited to their health, using sturdy footwear, and keeping living spaces free of clutter that could cause falls. Middle-aged adults, especially women approaching menopause and men with risk factors like smoking or long-term steroid use, are encouraged to talk with a doctor about their bone health before problems arise.

By using World Osteoporosis Day to raise awareness, promote early diagnosis and encourage healthy habits, countries like Bangladesh can help reduce the burden of preventable fractures. Protecting bone health means protecting independence, mobility and quality of life for millions of older people and their families.
