Association between 25(OH)D Levels and Primary Arterial Hypertension

This study seeks to determine whether patients from a family physician's practice have an association between 25(OH)D levels and primary arterial hypertension (AH). The study included a total of 1068 patients who were tested for vitamin D status. Data from their outpatient medical records were analysed: sex, age, body mass index, glomerular filtration rate, and the history of AH. Primary arterial hypertension was diagnosed in 63% of the patients. The mean vitamin D level in the study population was 25 ng/ml, and the largest group, or 36%, was found to have vitamin D deficiency (20-29 ng/ml). Odds ratio (OR) for hypertension was not inversely correlated with higher vitamin D levels. No statistically significant increase was observed in OR in a multi-factor analysis. The relevant hypertension ORs were 1.8 (0.4-7.5), 1.1 (0.3-4.5), 1.7 (0.4-7.2) and 0.7 (0.1-4.8) 30 ng/ml to 45 ng/ml, 20 to 29 ng/ml, 10 to 19 ng/ml, and < 10 ng/ml compared to the group of ³ 45 ng/ml. No association was found between 25(OH)D levels and the primary arterial hypertension in study participants.
