Introduction: Vitamin D (VD) has a key role in several metabolic processes and its deficiency may have adverse health implications. The study focuses on prediabetic patients and the impact of VD status on their cardiovascular health. Aims: To determine the association between VD status and cardiovascular risk in prediabetic patients. Methods: The study included retrospectively collected data on 270 prediabetic patients and 299 normoglycemic subjects. Prediabetes was diagnosed by HbA1c as 5.7- 6.4%. Increased cardiovascular risk was assessed based on the Atherogenic Index of Plasma (AIP) more than 0.1. Lipid parameters and AIP were compared between two groups by t-test and chi-square and separately by ANOVA under VD categories; Sufficient (__ampersandsigngt;75 nmol/L), Insufficient (50-75 nmol/L) and Deficient ( 0.1). Results: VD deficiency was more prevalent in prediabetic subjects (56.9%; 57.9 + 20.8 nmol/L; p__ampersandsignlt;0.05). AIP was significantly higher in prediabetic subjects (0.13 + 0.29; p __ampersandsignlt; 0.05). AIP showed a significant increasing trend with declining Vitamin D status among prediabetic patients (p__ampersandsignlt;0.05) but not in normoglycemic subjects. The risk of prediabetes (p = 0.141) and unfavourable AIP (p __ampersandsignlt;0.05 ) decreased with improved Vitamin D status. Conclusion: Vitamin D status is important in prediabetes as it potentially increases cardiovascular risk in the already vulnerable group.
