Which lifestyle factor is a risk factor for osteoporosis?

• A. Smoking Tobacco
• B. Regular Exercise
• C. Dairy Avoidance
• D. Healthy Sleep

Answer: (A)

Osteoporosis risk is influenced by lifestyle choices that affect how bone is built up and broken down. Smoking tobacco introduces toxins like nicotine that disrupt this process by reducing osteoblast (bone-forming cells) activity, increasing osteoclast (bone-destroying cells) activity, and impairing calcium metabolism and hormone balance. This combination leads to lower bone density and a higher risk of fractures over time. In contrast, regular exercise—especially weight-bearing activities—tends to strengthen bones and reduce osteoporosis risk. While not consuming dairy can lower calcium intake, calcium can still be obtained from other sources, so dairy avoidance is a less consistent risk factor. Healthy sleep supports general health but does not directly raise osteoporosis risk the way tobacco use does. So, smoking tobacco stands out as the lifestyle factor that increases osteoporosis risk.
