Introduction: Obesity is a known risk factor for hypovitaminosis D and although several studies point out that higher adherence to the Mediterranean Diet (Diet-Med) is associated with higher dietary vitamin D intake, there are very limited data on the influence of Diet-Med on serum 25-Hydroxy Vitamin D (25OHD) levels. Our aim was to evaluate the relationship between adherence to Diet-Med and vitamin D status in obese patients.

Material and Methods: Retrospective observational study of a sample of 125 candidates for bariatric surgery evaluated during 2018-2022 at the UNCyD of the Hospital San Cecilio of Granada. Sociodemographic, anthropometric data and serum 25OHD levels were analyzed. Adherence to Diet-Med was assessed using the PREDIMED-score (<7 points=low adherence).

Results: Prevalence of good adherence to Diet-Med: 54.4%. 68.8% women. Mean age 45.3±12.4 years. Mean weight 126±24 kg and mean BMI 45±6.8 kg/m². The group with good adherence to Diet-Med presented higher age (47.6±10.6 vs 42.6±12.8, P=0.03) and higher number of patients with vitamin D sufficiency (25OHD≥20 ng/ml: 46.3% vs 28.1%, P=0.037). Furthermore, a statistically significant positive relationship was observed between good adherence to Diet-Med and vitamin D sufficiency (r= 0.187, P=0.038) with an odds ratio of 2.207 (95% CI: 1.0141-4.677, P=0.039).

Conclusion: The association between adherence to Diet-Med and vitamin D status in obese subjects is demonstrated.
