Scholarcy highlights

  • We tested the hypothesis that the age-related decline in skin thickness may contribute to the age-related decline in serum 25-hydroxyvitamin D
  • Seasonal variation of serum 25(OH)D was greater in lean than in fat subjects, which we attributed to the larger fat mass and consequent larger pool size in the latter group
  • The results suggest that the tendency for serum 25(OH)D to fall with age is due in part to the age-related decline in skin thickness
