What is a common risk factor for developing osteoporosis?

Aging and inactivity is a well-established risk factor for developing osteoporosis. As individuals age, there is a natural decline in bone density due to a combination of hormonal changes and decreased physical activity. The body resorbs bone faster than it can form new bone tissue, leading to weaker bones. Inactivity contributes to this condition by not stimulating bone maintenance and strengthening, which is supported by weight-bearing exercises that help build and maintain bone mass. Engaging in regular physical activity has been shown to improve bone health, while a sedentary lifestyle accelerates bone loss, making older adults more susceptible to osteoporosis.

The other options indicate positive behaviors or conditions that typically support bone health. For instance, high calcium intake and regular exercise are both protective factors against osteoporosis. Moderate alcohol consumption can also be less detrimental compared to heavy drinking, as some studies suggest that moderate levels might actually have a neutral or slightly beneficial influence on bone density. Thus, focusing on aging and inactivity directly addresses factors that lead to the deterioration of bone health, ultimately resulting in an increased risk of osteoporosis.
