Osteoporosis: prevention, diagnosis, and management

Area of Science:

• Gerontology
• Public Health
• Endocrinology

Background:

• Osteoporosis is a significant public health issue, often preventable through lifestyle modifications.
• Key risk factors include low calcium and vitamin D, physical inactivity, smoking, and excessive alcohol/caffeine intake.
• Hip fractures are a severe consequence of osteoporosis with substantial personal and public health implications.

Purpose of the Study:

• To identify modifiable risk factors for osteoporosis and hip fractures.
• To highlight the importance of bone mineral density (BMD) and clinical risk factors in assessing fracture risk.
• To review effective treatments for retarding postmenopausal bone loss.

Main Methods:

• Review of established risk factors for osteoporosis and hip fractures.
• Identification of additional independent predictors of hip fracture risk from the Study of Osteoporotic Fractures.
• Assessment of fracture risk using BMD measurements (dual-energy x-ray absorptiometry) and clinical evaluation.

Main Results:

• Identified numerous modifiable risk factors, including lifestyle choices and medication use (e.g., long-acting benzodiazepines).
• Highlighted predictors such as maternal hip fracture, weight changes, height, hyperthyroidism, and physical frailty.
• Demonstrated the effectiveness of estrogen, calcitonin, and bisphosphonates in reducing bone loss.

Conclusions:

• Osteoporosis prevention is achievable through early intervention targeting modifiable risk factors.
• Accurate fracture risk assessment combines BMD, fracture history, and clinical risk factors.
• Pharmacological interventions like estrogen, calcitonin, and bisphosphonates are effective in managing postmenopausal bone loss.
