Low Bone Mineral Density

Low Bone Mineral Density is one of the modifiable risk factors tracked by the IHME Global Burden of Disease Study. The attributable deaths shown here represent the estimated number of deaths that could be prevented if exposure to this risk factor were eliminated or reduced to optimal levels. Understanding risk factor contributions helps prioritize public health interventions and policy decisions.

Risk factor attribution uses comparative risk assessment methodology. A single death may be partially attributed to multiple risk factors, so attributable death counts should not be summed across risk factors. Data covers 204 countries from 1990 to the latest available year.

Low bone mineral density (osteoporosis) increases fracture risk and contributes to approximately 200,000 deaths annually, primarily through hip fracture-related complications in the elderly. Hip fractures carry a one-year mortality rate of 20-30% in those over 80. An estimated 200 million people worldwide have osteoporosis, with prevalence increasing steeply with age and being higher in women (especially post-menopausal). Europe, North America, and East Asia have the highest reported hip fracture rates. Risk factors include female sex, low body weight, physical inactivity, smoking, alcohol excess, corticosteroid use, calcium and vitamin D deficiency, and genetic predisposition. The burden is projected to increase dramatically as populations age: global hip fracture incidence may triple by 2050. Beyond mortality, fractures cause chronic pain, disability, loss of independence, and substantial healthcare costs.

Low Bone Mineral Density contributes to mortality from hip fractures, vertebral fractures, fall-related mortality. The magnitude of impact varies by country depending on exposure levels, population demographics, and the availability of preventive and treatment services.

Adequate calcium and vitamin D intake throughout the lifespan, weight-bearing physical activity, and fall prevention programmes reduce fracture risk. Dual-energy X-ray absorptiometry (DEXA) screening identifies those at high risk. Bisphosphonates, denosumab, and teriparatide (anabolic therapy) are effective pharmacological treatments. Fall prevention — through exercise programmes, home hazard modification, medication review, and vision correction — is critical in elderly populations. Hip protectors provide mechanical fracture prevention in nursing home residents.
