What is the primary risk factor for osteoporosis?

• A. High diet calcium
• B. Age
• C. Physical activity
• D. Genetics

Answer: (B)

The primary risk factor for osteoporosis is age. As individuals get older, bone density naturally decreases due to a gradual loss of bone mass and changes in bone remodeling. This process can begin in the late 30s and can accelerate in postmenopausal women due to decreased estrogen levels, which plays a crucial role in maintaining bone density.

Older adults are at a significantly higher risk of developing osteoporosis because their bones lose calcium and other minerals more rapidly than they can be replenished. Age-related bone loss is compounded by the fact that many older adults may not engage in sufficient physical activity or may have dietary deficiencies, both of which are critical in maintaining healthy bone mass throughout life.

In contrast, while genetics can play a role in determining bone density and the likelihood of osteoporosis, it is the aging process that has the most direct impact, making age the predominant risk factor in the development of this condition. Thus, recognizing the role of aging in osteoporosis is essential for understanding prevention and treatment strategies.
