In recent years, multiple epidemiological studies have been conducted on vitamin D, revealing its potential role in preventing various bone and non-bone related diseases. However, the effectiveness of vitamin D in reducing inflammation, preventing infections, and fighting cancer is contingent on individual-specific extrinsic and intrinsic factors that impact one's vitamin D status. We are interested in examining the relationship between vitamin D levels and various socio-clinical-pathological parameters. Our study involved 789 participants, consisting of 715 women and 74 men, where we measured their plasma 25(OH)D3 level. We found that 57.16% were deficient in vitamin D, 35.11% had insufficient levels, and only 7.73% had a normal level. We observed a correlation between vitamin D levels and both sex and diabetes, however, we did not find any correlation with sun exposure, outdoor sports activity, high blood pressure, or age. Additionally, we suspect that there may be a relationship between vitamin D status and the participant's region of residence. Some of our findings align with existing literature, but we also observed regional differences in the results. The status of an individual's vitamin D can be affected by a variety of intrinsic and extrinsic factors. Therefore, it would be beneficial to broaden the scope of the sample population and include additional parameters to be examined in future studies.
