From the Guidelines
Osteoporosis and osteopenia are distinct conditions characterized by decreased bone density, with osteoporosis being more severe and associated with a higher risk of fractures, and the most recent evidence suggests that treatment approaches should prioritize lifestyle modifications and medication therapy to prevent fractures and improve bone health 1.
Key Differences Between Osteoporosis and Osteopenia
- Osteopenia is a milder condition with a T-score between -1.0 and -2.5, while osteoporosis is diagnosed with a T-score of -2.5 or lower.
- Osteoporosis is associated with a higher risk of fractures, particularly vertebral and hip fractures.
- Treatment approaches differ based on severity, with osteopenia often focusing on lifestyle modifications and osteoporosis requiring medication therapy in addition to lifestyle changes.
Diagnosis and Treatment
- Diagnosis is typically made using a dual-energy X-ray absorptiometry (DEXA) scan, which measures bone mineral density.
- Treatment approaches for osteoporosis may include bisphosphonates, hormone therapy, selective estrogen receptor modulators, or biologics like denosumab, while osteopenia often focuses on lifestyle modifications like weight-bearing exercise, adequate calcium and vitamin D intake, smoking cessation, and limiting alcohol consumption 1.
- The most recent evidence suggests that pharmacologic interventions, such as bisphosphonates and denosumab, can reduce the risk of fracture in patients with osteoporosis, and that lifestyle modifications, such as exercise and adequate calcium and vitamin D intake, can help prevent bone loss and reduce the risk of fracture 1.
Management and Prevention
- Management of bone health should be part of an overall survival plan, and clear communication between patients and clinicians is essential for effective monitoring and treatment of bone loss.
- Healthy lifestyle behaviors, such as a balanced diet, regular exercise, and adequate calcium and vitamin D intake, can help prevent bone loss and reduce the risk of fracture.
- Pharmacologic interventions, such as bisphosphonates and denosumab, can be effective in reducing the risk of fracture in patients with osteoporosis, but should be used in conjunction with lifestyle modifications and under the guidance of a healthcare professional 1.
From the Research
Osteoporosis vs Osteopenia: Key Differences
- Osteoporosis is a systemic skeletal disorder characterized by bone loss, which leads to impaired bone strength and an increased risk of fractures 2.
- Osteopenia, on the other hand, is a condition where bone density is lower than normal, but not low enough to be classified as osteoporosis.
- Both conditions can increase the risk of fractures, but osteoporosis is generally considered more severe 3.
Treatment and Prevention
- Bisphosphonates are widely used in the treatment of osteoporosis and have been shown to reduce fractures in women with osteoporosis 4, 2.
- There is increasing evidence that bisphosphonates are also effective in women with osteopenia, in whom the majority of fractures occur 5.
- In addition to pharmacotherapy, adequate intake of calcium and vitamin D, avoidance of smoking and excessive alcohol intake, weight-bearing and resistance-training exercise, and fall prevention are included in the fracture prevention armamentarium 3.
Exercise Guidelines
- Resistance and impact training have been shown to consistently maximize bone strength, improve body strength and balance, and eventually reduce fall incidences in patients with osteoporosis and osteopenia 6.
- A multi-component exercise mainly comprised of resistance and impact exercise seems to be an effective strategy to attenuate the risk factors of osteoporosis and osteopenia 6.
- Exercise guidelines and individualized exercise plans have significant potential to reduce the morbidity and mortality of osteoporosis 6.
Diagnosis and Risk Assessment
- Osteoporosis detection, diagnosis, and treatment should be routine practice in all adult healthcare settings 3.
- Bone densitometry is used to establish fracture probability and diagnose osteoporosis 3.
- Fracture risk thresholds for pharmacologic intervention are established based on bone density and other risk factors 3.
