Association of serum Vitamin D levels with Hypertension

Abstract

Objectives: The objective of our study was to identify the effect of low serum vitamin D levels on hypertension & to make a comparison of levels of vitamin D in hypertensives and healthy individuals.
Materials and Method: A cross-sectional comparative study carried out in Cardiology Department of Shaikh Zayed Hospital and Punjab Institute of Cardiology, which involved measurement and comparison of serum Vitamin D levels in 64 subjects, categorized in two groups; hypertensives and normotensives, in order to establish a potential association between vitamin D levels and hypertension.
Results: Our study showed that Serum Vitamin D was equally sub-optimal in all participants of study, including both hypertensive group and the healthy controls. As a result of this finding, a clear pattern of association of vitamin D deficiency with hypertension could not be seen. Mean ±SD Vitamin D levels was 19.5±10.0 ng/L in hypertensives and 19.5±13.6 in healthy individuals. This study did not lead to establishment of an association between hypertension and vitamin D levels.
Conclusion: Because of deficiency of Vitamin D in general population in this region, our study failed to show an association between Vitamin D and hypertension. Further exploration is needed in this regard.
