Introduction: The prevalence of vitamin D deficiency is high, and yet still little recognized and treated. Cardiovascular diseases are the leading causes of morbidity and mortality worldwide and the emergence of evidence with the link suggesting an association between vitamin D deficiency and cardiovascular risk (CVR), it is pertinent to better understand this association.

Objective: This study aimed to relate the levels of 25 (OH) D in obese patients with the cardiovascular risk.

Methodology: Cross-sectional observational study with a sample of 31 individuals between 40 and 64 years, of both sexes diagnosed with obesity. They evaluated sociodemographic data, solar exposure and use of sunscreen, skin color phototype of skin color, sources of vitamin D, physical activity, anthropometric data, clinical and biochemical and CVR.

Results: The average value of 25(OH) D was 15.6 ng/ml, 71.0 and 22.6% had deficiency and insufficiency, respectively. We observed lower levels of 25(OH) D in smokers, those with less solar exposure time, with a higher waist-to-height ratio and in those with lower levels of DBP. We did not find a statistically significant association between vitamin D and CVR.

Conclusions: We found a high prevalence of vitamin D deficiency in our sample of patients with obesity and a significant association with the waist-to-height ratio. Despite the evidence that suggests that vitamin D deficiency is associated with an increased CVR, we found this association but without statistical significance. The measurement of total 25(OH) D routinely in people with central obesity can help identify those who are at most CVR.
