A new study of men and women in England, Scotland and Wales suggests that Low levels of vitamin D may contribute to chronic pain in women.  The study did not find a similar link for men.

The study had 6824 participants and is published in the journal Annals of Rheumatic Diseases.

Women with vitamin D levels in the health range suffered from the lowest rate of chronic pain, while about women with low vitamin D levels had the highest rates of chronic pain (14.4 percent).

Not surprisingly, smokers Higher rates of chronic pain were reported by smokers, non-drinkers, and overweight and underweight people. Among women, vitamin D levels also seemed to be a major factor, BBC News reported.
Because no link was seen for men, researchers suspect female hormones may be a factor in the study outcome.
