Osteoporosis is characterized by a decrease in bone density, leading to fragile bones and a higher risk of fractures. This condition often develops due to a combination of age-related factors and dietary influences, such as insufficient intake of calcium and vitamin D, which are critical for maintaining strong bones. As individuals age, the body's ability to absorb these vital nutrients decreases, and bone resorption often exceeds formation, resulting in weakened and porous bones.

In contrast, osteoarthritis and rheumatoid arthritis primarily affect the joints rather than bone density, focusing more on inflammation and joint degeneration. Alzheimer's disease, a neurodegenerative condition, does not relate directly to bone density but instead affects cognitive function. Thus, osteoporosis is the condition specifically associated with impaired bone density due to age and dietary factors.
