STUDY OF VITAMIN D LEVELS AND ITS CORRELATION WITH AMBULATORY STATUS IN STROKE SURVIVORS : A CROSS SECTIONAL STUDY.

Abstract

Background – Stroke can lead to impaired mobility and disability. There are chances of decreased exposure to sunlight and decreased Vitamin D levels after stroke. This study was done to assess the vitamin D status in stroke survivors and its correlation with duration and ambulatory status of stroke. Methods – This cross sectional study included 100 patients of stroke. Patients were assessed after history and examination for their Serum Vitamin D levels, ambulatory status by Modified Rankin Scale (MRS). MRS grade 1-3 were considered ambulatory and MRS grade 4 and 5 were considered non ambulatory. Statistical analysis was done using chi square test for qualitative variables, unpaired t test for quantitative variables, and pearson correlation. P value < 0.05 was taken significant. Results –72 patients had Vitamin D levels less than 30ng/ml (20.42 ± 5.89 ng/ml). Significant negative correlation was observed between duration of stroke and Serum Vitamin D levels. Out of 41 non ambulatory patients, 38 were Vitamin D deficient (P<0.05). negative Correlation was present in Modified Rankin Scale and Serum Vitamin D levels. Conclusion –Vitamin D Deficiency is present in chronic non ambulatory stroke patients.
