Evaluation of Risk Factors for Multiple Sclerosis (MS) in Azar Cohort Population

Abstract

Multiple sclerosis (MS) is a demyelinating. Genetic predisposition and environmental factors both contribute to the pathology of MS. In this study we aim at evaluating the risk factors of MS in Azar cohort population. Materials and Method: In this is a cross-sectional study, All azar cohort subjects with MS diagnosis at the beginning of the study were included as case population. Three-fold of their sample size was chosen from healthy subjects as the control group. Eventually all the risk factors were evaluated in both groups. Results: Overall 21 patients and 63 healthy individuals were included in this study. According to our results 1 point decrease in the BMI increases the risk of MS by 21%. One hour increase in the sleep duration increases the risk of MS by 53%. Vitamin D supplementation decreases the risk of MS. There was no significant difference among groups regarding age, level of education, smoking status, and using social media.
