To Find Out the Association of Vitamin D Levels on Blood Pressure

Abstract

Objective: To explore the association of vitamin D levels on the Blood Pressure.

Study Design: Observational / cross sectional study

Place and Duration of Study: This study was conducted at the Department of Physiology at Khyber Medical College/Teaching Hospital in Peshawar from January, 2020 to December, 2020.

Materials and Methods: Subjects were recruited according to the inclusion criteria. Patients were divided into three cohorts; Stage I hypertension (Group I), Stage II (Group II) hypertension and a third group (Control group). Blood for Vitamin D Levels was taken and analysed at the Hospital Lab. Blood Pressure readings in mm Hg via Yamasu mercury sphygmomanometer. All information was recorded using proforma and analysed on IBM SPSS for MacBook, Version 26.0.

Results: Mean and Standard Deviations (SD) for the levels of vitamin D (ng/mL) recorded as 34.77 ± 7.18 for control group, 26.91 ± 9.75 for Group I and 26.21 ± 9.14 for Group II. For the Control Group, Mean and SD for systolic blood pressure (SBP) and diastolic blood pressure (DBP) were recorded as 111.52 ± 4.69 mm Hg and 74.36 and ± 3.41mm Hg respectively. Group I, Mean and SD for SBP and DBP were recorded as 130.17 ± 7.93 mm Hg and 92.09 ± 5.46 mm Hg respectively. Group II, Mean and SD for SBP and DBP were recorded as 145.08 ± 18.98 mm Hg and 102.98 ± 11.95 mm Hg respectively.

Conclusion: Our study finds out a positive association of lower vitamin D levels with raised Blood Pressure.
