The Silent Disease: Why Osteoporosis Screening Matters

Osteoporosis is often called the "silent disease" because bone loss occurs without symptoms until a fracture happens. By the time many individuals learn they have osteoporosis, they have already experienced a vertebral compression fracture, hip fracture, or other debilitating skeletal event.

The statistics are sobering: one in three women and one in five men over age 50 will experience an osteoporotic fracture during their remaining lifetime. Hip fractures in particular carry significant mortality risk—up to 20% of hip fracture patients die within one year, and many survivors never regain their previous functional independence.

The good news is that osteoporosis is largely preventable and treatable when identified early. This makes risk assessment critically important.

The IOF One-Minute Risk Test: An Evidence-Based Approach

The osteoporosis risk assessment utilised in Your Health Compass is based on the International Osteoporosis Foundation's (IOF) One-Minute Risk Test. The IOF is the world's largest nongovernmental organisation dedicated to osteoporosis prevention, bringing together leading researchers and clinicians globally.

The IOF risk test was designed to identify individuals who warrant formal bone density testing (DEXA scan) or who should implement aggressive bone-protective strategies. Each question addresses risk factors with documented relationships to bone mineral density and fracture probability.

Understanding the Biology of Bone Loss

Bone is living tissue undergoing constant remodelling. Osteoclasts break down old bone while osteoblasts build new bone. In healthy young adults, these processes remain balanced. However, various factors can tip the balance toward net bone loss. The IOF risk assessment captures the most significant of these factors.

Parental History of Osteoporosis or Fracture: Genetic factors account for 60-80% of peak bone mass variation. If a parent had osteoporosis or experienced a fragility fracture (fracture from minimal trauma), you likely inherited genes that affect bone density, collagen structure, or calcium metabolism.

Parental Kyphosis (Stooped Back): A "dowager's hump" typically indicates multiple vertebral compression fractures from osteoporosis. This visible sign in parents suggests heritable bone fragility.

Age Over 40: Bone mass peaks around age 30 and declines thereafter. After age 50, bone loss accelerates, particularly in women following menopause when oestrogen's bone-protective effects diminish.

Previous Fragility Fracture: A fracture occurring from a standing height fall or less indicates bone strength is already compromised. Previous fracture is among the strongest predictors of future fracture—risk increases two to fourfold.

Frequent Falls: Independent of bone density, fall risk determines fracture probability. Frequent falls multiply the opportunities for a fragile skeleton to experience traumatic loading.

Height Loss: Losing more than 3 centimetres (1 inch) of height after age 40 often indicates vertebral compression fractures, which may have occurred silently. This is a clinical sign of established spinal osteoporosis.

Low Body Weight: Underweight individuals (BMI below 19) have less mechanical loading on bones—and bones strengthen in response to load. Additionally, very low body weight may indicate nutritional insufficiency affecting bone metabolism.

Corticosteroid Use: Glucocorticoid medications (prednisone, cortisone) directly suppress osteoblast function and enhance osteoclast activity. Prolonged use is among the most common causes of secondary osteoporosis.

Rheumatoid Arthritis: This autoimmune condition increases fracture risk through multiple mechanisms: chronic inflammation promotes bone resorption, the disease often requires corticosteroid treatment, and reduced physical activity due to joint symptoms decreases mechanical bone loading.

Thyroid/Parathyroid Disorders: Hyperthyroidism accelerates bone turnover with net loss. Hyperparathyroidism directly increases bone resorption through parathyroid hormone's effects on osteoclasts.

Alcohol Excess: Alcohol directly inhibits osteoblast function, interferes with calcium absorption, affects vitamin D metabolism, and increases fall risk. More than two drinks daily significantly elevates fracture probability.

Smoking: Tobacco use impairs bone cell function, reduces calcium absorption, affects hormone levels that protect bone, and accelerates the rate of bone loss.

Physical Inactivity: Weight-bearing exercise stimulates bone formation through mechanical signalling pathways. Sedentary individuals lack this crucial stimulus, and muscle weakness from inactivity further increases fall risk.

Calcium and Dairy Avoidance: Calcium is the primary mineral component of bone. Inadequate intake forces the body to mobilise skeletal calcium to maintain blood calcium levels for critical functions like nerve conduction and muscle contraction.

Limited Sun Exposure: Vitamin D, synthesised in skin during sun exposure, is essential for calcium absorption. Deficiency leads to secondary hyperparathyroidism and accelerated bone loss.

Early Menopause (Women): Oestrogen inhibits bone resorption. Women who experience menopause before age 45, whether naturally or surgically, face an extended period of oestrogen deficiency with cumulative bone loss consequences.

Extended Amenorrhoea (Women): Prolonged absence of menstruation (outside pregnancy) indicates low oestrogen states—often from excessive exercise, eating disorders, or other hormonal dysfunction—with corresponding bone loss.

Low Testosterone (Men): Testosterone contributes to bone maintenance in men. Hypogonadism accelerates male bone loss and increases fracture risk.

Interpreting Your Risk Score

Score 0-2 (Low Risk): Few risk factors present. Continue bone-healthy habits: adequate calcium (1000-1200mg daily), vitamin D (600-800 IU daily), weight-bearing exercise, and fall prevention strategies.

Score 3-5 (Moderate Risk): Several risk factors warrant attention. Optimise modifiable factors—nutrition, exercise, smoking cessation, alcohol moderation. Discuss bone health with your healthcare provider, particularly if you're approaching or past age 50.

Score 6-9 (Elevated Risk): Multiple risk factors suggest formal bone density testing (DEXA scan) is advisable. If osteopenia or osteoporosis is confirmed, various treatments can reduce fracture risk by 40-70%.

Score 10+ (High Risk): Substantial risk factor burden. We strongly recommend prompt consultation with your healthcare provider about bone density testing and intervention strategies. Effective treatments exist including bisphosphonates, denosumab, teriparatide, and romosozumab.

Prevention and Treatment: Highly Effective

Perhaps the most important message is that osteoporosis is remarkably treatable. Lifestyle measures—calcium, vitamin D, weight-bearing exercise, fall prevention—can slow bone loss and reduce fracture risk. When pharmacological intervention is warranted, available medications can reduce vertebral fracture risk by 40-70% and hip fracture risk by 40-50%.

Early identification through risk assessment enables early intervention—potentially preventing the devastating fractures that occur when osteoporosis goes unrecognised.
