Background: Previous cross-sectional studies have shown that Parkinson’s disease (PD) patients have lower serum 25- hydroxy vitamin D (25(OH)D) concentrations than controls. whether the research in other regions findings are generalizable to China populations remains untested in other studies. In this case-control study we examined the Correlation between 25-hydroxy-vitamin D and Parkinson's disease. Methods: : We establish an association between deficiency of 25-hydroxy-vitamin D and PD in a case-control study of 100 PD patients and 100 control subjects free of neurologic disease in the First Affliated Hospital of Xinjiang Medical University. Results: : Total 25-hydroxy-vitamin D levels, were deficient in 21% of patients with PD compared with 4% of controls. In univariate analyses Plasma levels of 25-hydroxy-vitamin D were associated with PD(pConclusions: : Our study reveals an association between 25-hydroxy-vitamin D and PD.Patients with incident PD had significantly lower serum 25(OH)D concentrations than age-matched controls, High-risk PD patients with vitamin D deficiency who have not yet developed exercise impairment, these populations should undergo vitamin D measurement and vitamin D treatment as soon as possible.
