Vitamin D deficiency is a public health concern affecting many individuals as it is highly prevalent in all parts of the world. Recent studies have reported an association of vitamin D deficiency with cardiometabolic alterations such as dyslipidemia. The study aimed to evaluate vitamin D and lipid profile levels among the Libyan adult population and investigate the correlation of vitamin D deficiency with the alteration of lipid profile levels. A cross-sectional study was conducted at Janzour Hospital among 193 subjects (107 males and 86 females) whose ages ranged between 20 and 50 years over three months from Sept to Dec 2023. Vitamin D, cholesterol, triglyceride, low-density lipoprotein, and high-density lipoprotein levels were estimated. The total mean vitamin D levels were 8.31±4.74, 23.83±2.78, and 42.67±7.95 ng/dl for deficiency, insufficiency, and sufficiency, respectively. The findings revealed significant alterations in cholesterol (increase), triglyceride (increase), LDL-cholesterol (increase), and HDL-cholesterol (decrease) among subjects who had vitamin D deficiency or insufficiency as compared to subjects having vitamin D sufficiency. Vitamin D levels were negatively correlated with cholesterol, triglyceride, and LDL cholesterol, and they were positively associated with HDL cholesterol. The incidence of dyslipidemia is higher in the vitamin D deficiency group than in the insufficiency and sufficiency groups. It is essential to frequently monitor lipid profiles among vitamin D-deficient individuals to avoid subsequent disorders or damages associated with the alterations of lipid profile patterns.
