ABSTRACT: Background
Multiple sclerosis (MS) onset is caused by genetic and environmental factors. Vitamin D has been identified as contributing environmental risk factor, with higher prevalence at latitudes further from the equator. Mongolia, at 45°N, has limited sunlight exposure, increasing the population's risk for vitamin D deficiency.Objectives
To compare vitamin D levels between persons with MS (pwMS) and persons without MS and to identify factors associated with low vitamin D.Methods
We investigated associations with vitamin D levels using data from MS cases and controls from Mongolia. We used linear mixed-effects regression with fixed effects (case status, sociodemographics, and predefined variables) and participant-specific random intercepts.Results
