Introduction:
Vitamin D deficiency is known to be very common in adolescent girls and elderly women.
Aim:
To analyze vitamin D status, vitamin D intake and solar exposure of Spanish participants in The Five Countries Study of Optiford Project.
Methods:
Questionnaires approved and validated of lifestyle and food consumption frequency applied. The biochemical analysis of 25-hidroxivitamin D and PTH and the evaluation of the solar exposure (dosymeter UV VioSpor) were carried out.
Results:
The average solar exposure of adolescent girls (1,519 J/m²) was double than elderly women (740 J/m²). The vitamin D status of adolescent girls in summer and winter was better than elderly women.
Conclusions:
Solar exposure habits are different between the two age groups. This fact, jointly to the lower body's capacity to synthesize Vitamin D through exposure to the sun in the elderly, may justify the worse vitamin D status in this age group.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
