Abstract
Background
High 25-hydroxyvitamin D concentrations have been associated with a reduced
risk of multiple sclerosis, with indications of a stronger effect among
young individuals.
Objective
Investigate the 25-hydroxyvitamin D association with multiple sclerosis and
test if this association is age dependent.
Methods
Prospectively drawn blood samples from individuals later developing
relapsing–remitting multiple sclerosis and controls matched for biobank,
sex, age and date of sampling, were analysed with liquid chromatography
tandem mass spectrometry.
Results
High levels of 25-hydroxyvitamin D (top quintile) were associated with a
reduced multiple sclerosis risk (odds ratio 0.68, 95% confidence interval
0.50–0.93).
Conclusion
These findings further support a role for vitamin D in MS aetiology.
