Objective: To investigate the associations of dyslipidaemia with varying levels of 25 hydroxy vitamin D3 deficiency.
Methods: This cross-sectional study was conducted at the Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from July 2016 to January 2017, and comprised patients having varying levels of 25 hydroxy vitamin D3 deficiency. Patients were stratified according to the severity of deficiency and had their serum fasting lipid profiles measured. SPSS 20 was used for data analysis.
Results: Of the 175 participants, 124(70.9%) were female and 51(29.1%) were male. The overall mean age of the patients was 47.7±12.2 years (range: 18-65 years). A very strong inverse correlation was found between vitamin D levels and low-density lipoprotein cholesterol (p<0.001) and a similar trend was obtained for vitamin D and total cholesterol (p<0.001). With regards to triglycerides, a modest inverse correlation was found (p=0.05). No significant association was documented between 25 hydroxy vitamin D3 levels and high-density lipoprotein cholesterol (p=0.3).
Conclusions: An inversely proportional relationship was found between total cholesterol, low-density lipoprotein cholesterol and triglycerides against varying levels of vitamin D deficiency.
