The aim was to determine the prevalence of vitamin D insufficiency in pregnant immigrant women assessed by the levels of 25-hydroxyvitamin D, parathyroid hormone (PTH) and alkaline phosphatase (ALP) as well as the correlation to musculoskeletal pain.

  • Sixty-eight pregnant immigrant women were included.
  • Fifty-one native Swedish pregnant women served as controls.

25-hydroxyvitamin D, PTH, ALP and musculoskeletal pain, rated on a visual analogue scale, were analyzed in all women in gestational week 12 and in the immigrant women at 6–12 months postpartum.
A significantly higher proportion of immigrant women (77.9%) had levels of 25-hydroxyvitamin D <25 nmol/l compared with 3.9% in controls.
Of the immigrant women, 29.4% had 25-hydroxyvitamin D levels <12 nmol/l, but none of the controls.
Musculoskeletal pain evaluated with a visual analogue scale (VAS) was significantly higher for the immigrant women than for the controls at gestational week 12. However, no within group correlation was seen between 25-hydroxyvitamin D levels, PTH or ALP and pain.
A significant negative correlation between changes in 25-hydroxyvitamin D and pain from gestational week 12 to postpartum was observed.
Hypovitaminosis D is prevalent in immigrant women living in Sweden.
There is an indication that pain might be associated with hypovitaminosis D.
