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.
