Which extra skeletal factors can affect osteoporosis risk?

• A. High protein diet and exercise
• B. Family history and genetics
• C. Tobacco use, alcohol consumption, and sedentary lifestyle
• D. Use of anabolic steroids

Answer: (C)

The correct answer identifies several lifestyle choices and substances that have been associated with an increased risk of osteoporosis. Tobacco use is well-documented in medical literature as a risk factor for osteoporosis because it can interfere with the body's ability to absorb calcium. Alcohol consumption can negatively affect bone health by reducing the body's ability to form new bone and by impacting the way hormones that regulate bone health function. A sedentary lifestyle contributes to weaker bones, as weight-bearing exercises are essential for maintaining bone density.

Understanding these factors is crucial for recognizing the broader picture of osteoporosis risk, which is not solely determined by dietary factors or genetics. High protein diets and exercise can actually be beneficial for bone health when done appropriately, while family history and genetics do play a role, they are not modifiable factors like tobacco use, alcohol consumption, and lifestyle choices. The option regarding the use of anabolic steroids does not align with the core aspects of osteoporosis risk, as their effects can vary and are not as clearly linked to the development of the condition as the factors listed in the correct choice.
