The effect of vitamin D levels on incident hypertension was not elucidated from our country perspective. The objective of the study was to report the level of vitamin D and its relation with incident hypertension among Bangladeshi adults.

This cross-sectional assessment was conducted in BSMMU for a period of one year. A total of 187 participants who had no known history of hypertension or comorbidities were included. Vitamin D assays and risk factor assessments for hypertension were performed for each patient. Data collection was performed using a structured questionnaire, and the study was conducted in compliance with the current declaration of Helsinki. Analysis was conducted with SPSS 26.

Out of 187 participants, 33 (17.6%) were newly diagnosed with hypertension. The predominant age group was 31-40 years (30.5%), and the average incidence was 36.76 ± 12.14 (SD) years. Sufficient, insufficient and deficient vitamin D were present in 11.8%, 32.6% and 55.6% of cases, respectively. Mean SBP and DBP were 117.41 ±12.84 and 76.87 ±9.46 mmHg, respectively. Hypertension was significantly more common in males than in females (p=0.047), but there was no association of vitamin D with hypertension (p=0.262). Both hypertensive and normotensive patients shared similar risk factor profiles in terms of age, sex, BMI, unhealthy food habits, extra salt intake, tobacco use, caffeine consumption, and hormonal contraceptives of females (p >0.05 for all).

Conclusion: Nearly one-fifth of participants had newly diagnosed hypertension, and more than fifty percent had vitamin D deficiency. However, vitamin D levels did not have any statistically significant association with incident hypertension.
