Abstract
BACKGROUND: Previous studies have associated vitamin D deficiency with cardiovascular disease (CVD) markers. The underlying mechanism remains elusive. Lipid and non-lipid markers of CVD and their relationship to vitamin D deficiency have not been assessed simultaneously. OBJECTIVE: To measure the association between vitamin D deficiency and non-lipid markers of CVD after adjustment of lipid markers. METHODS: This cross-sectional study used the following biological data, which was routinely collected in a general hospital laboratory database between 2011 and 2016: 25OH vitamin D [25(OH)D], creatinine, CKD-EPI eGFR (eGFR), fasting blood glucose (FPG), glycated hemoglobin (HbA1c), uric acid, γ-glutamyl transferase (γGT), C-reactive protein (CRP), total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, and a surrogate for CVD. Crude odds ratios (ORs) and ORs adjusted for lipid profile, gender and age using separate logistic regression models were derived. RESULTS: A total of 8658 subjects were included. Half had 25(OH)D < 20 ng/mL. 25(OH)D was associated with increased odds of CRP, eGFR, increased uric acid, γGT, FPG, HbA1c, male gender, CV status, and abnormal lipid markers. After adjustment for lipid markers, age, and gender, vitamin D deficiency was associated with increased odds of CRP, eGFR, γGT, FPG, HbA1c, and the surrogate for CVD. CONCLUSIONS: In this exploratory analysis, the first of its kind in the MENA region, vitamin D deficiency was associated with abnormal lipid markers, non-lipid markers of CVD, male gender, lower eGFR, and a surrogate variable for CVD. The association between vitamin D deficiency and non-lipid markers of CVD persisted after adjustment for lipid markers, age, and gender.
