Season of Birth

Season of birth is a good proxy for Vitamin D (for people far from the Equator)
Statistisically significant, but rarely greater than 20% change
Some problems need Vitamin D in 2 or 3 trimesters, so are not associated with SoB
Perhaps some people need more vitamin D all of their lives if poor birth month
