If could get less UVB - 1.5 million DALYs could have been avoided
If get no UVB 3,304 million DALYs would have been lost due to vitamin D deficiency diseases – rickets, osteomalacia and osteoporosis.
Figure 2.1 Schematic diagram of the relation between ultraviolet radiation (UVR) exposure and the burden of disease
A = Vitamin D insufficiency
B = Optimal
C= Skin cancers, eye disease
Horizontal line = Personal exposure to UVR relative to skin type
Points A and C represent inappropriate UVR exposure. Fair-skinned populations in Australia with high outdoor UVR exposure typify point A.
Point C represents people with insufficient UVR exposure, whose dietary vitamin D intake will also be important in determining their vitamin D status.
Point B represents optimal UVR exposure: a person with careful titration of correct UVR dose for skin type.
