Which risk factor involves both genetic and lifestyle influences?

• A. Turner's Syndrome
• B. Inactivity
• C. Vitamin D deficiency
• D. Hyperparathyroidism

Answer: (C)

The correct choice identifies vitamin D deficiency as a risk factor influenced by both genetic and lifestyle factors. Vitamin D is crucial for bone health, as it facilitates calcium absorption in the intestines and maintains proper bone mineralization. Genetics can play a role in how well an individual can synthesize or metabolize vitamin D, especially due to variations in vitamin D receptor genes. Lifestyle influences also significantly affect vitamin D levels. For example, individuals with limited sun exposure, certain dietary habits lacking in vitamin D-rich foods (like fatty fish, fortified dairy products, and egg yolks), and those who use sunscreen can all experience lower levels of vitamin D. Additionally, lifestyle habits such as sedentary behavior can lead to insufficient production of vitamin D from sun exposure. This combination of genetic predispositions and lifestyle choices makes vitamin D deficiency a multifaceted risk factor affecting overall bone health, particularly in conditions like osteoporosis. Other options presented in the question, while relevant to bone health in specific contexts, do not encompass both genetic and lifestyle influences to the same extent that vitamin D deficiency does.
