Kristinsson JÖ, Valdimarsson Ö, Sigurdsson G, Franzson L, Olafsson I & Steingrimsdottir L. (Reykjavik Hospital, University of Iceland, Reykjavik, Iceland). Serum 25-Hydroxyvitamin D Levels and bone mineral density in 16–20 years old girls: lack of association. J of Intern Med 1998; 243: 381–88

In conclusion, our results indicate that the vitamin D requirements for normal bone mineral accrual in adolescent and young adult girls may be lower than presumed and suggest that calcium and phosphate concentrations in plasma may be regulated in this age group to some extent by other factors which needs to be further clarified. However, the important question of the effect of repeated, cyclical vitamin-D nadir on bone mass in young people needs to be explored in a longitudinal survey.
