Which of the following is considered a risk factor for low vitamin D status?
Introduction: Vitamin D is an essential nutrient that is required by the body for the absorption of calcium. It is present naturally in egg yolk, sea food, and milk. Our body can also synthesize vitamin D using sunlight, mainly from the cholesterol in body. Vitamin D also has roles in immune, muscular and nervous systems. Deficiency of vitamin D can lead to osteoporosis.
Reason for the correct answer:
Option a. is given as “Dark skin pigmentation”
Dark colored skin is associated with higher melanin levels in the skin which leads to decreased ultraviolet (UV) B absorption in these individuals. Therefore, endogenous synthesis of vitamin D through UV-B is reduced in dark skin pigmentation leading to increased risk for low vitamin D status.
Hence, option a. is correct.
Reasons for the incorrect answer:
Option b. is given as “Light skin pigmentation”
Light skin pigmentation is not a risk factor for low vitamin D status because such individuals do not have excess melanin pigmentation in their skin and therefore, their skin can synthesize vitamin D from sunlight...
