Abstract: Objective This study aimed to determine the prevalence of vitamin D deficiency in patients with hypertension and investigate the association between vitamin D level and blood pressure control. Methods A cross-sectional study was conducted on patients with hypertension who visited family medicine clinics of King Abdulaziz National Guard Hospital, Al Ahsa, in 2017. Data were collected through self-administrated questionnaire that included both demographic and lifestyle factors with blood pressure and vitamin D level, which were measured through a medical chart review. Results Of the 246 patients who participated in the study, 51.6 % had uncontrolled hypertension. Current intake of vitamin D was noted in 56.9 % of patients with hypertension. A majority of patients with hypertension (78.6 %) had vitamin D insufficiency, whereas 10 % had vitamin D deficiency. There was a statistically significant mild negative correlation between systolic blood pressure (SBP) and vitamin D level (r=-0.14, p=0.04). Conclusion Vitamin D insufficiency/deficiency is particularly common among patients with hypertension, with mild negative correlation between vitamin D level and SBP. It is recommended to maintain optimal vitamin D level to control blood pressure.
