Correlation of serum vitamin D with lipid profiles in middle-aged and elderly Chinese individuals
摘要
Background and Objectives: Deficiency of vitamin D has been associated with various health conditions. The purpose of this study was to evaluate the associations between the serum 25OHD concentration and lipid profiles in Chinese individuals. Methods and Study Design: Serum 25OHD and lipid profiles were obtained for a cross sectional sample of 10100 individuals aged 40-75 years from Lanzhou city, which is located in western China. Linear-by-linear association, partial correlation analysis and multiple logistic regression analysis were used to evaluate associations between serum 25OHD concentration and lipid profiles. Results: 10038 subjects aged 40-75 years were included in the study. The 25OHD deficient and insufficient groups had higher TC, LDL-C and TG when compared to the optimal group. The dyslipidemia rates of vitamin D deficiency, insufficiency, and sufficiency groups were 45.4%, 41.6%, 38.8%, respectively. The prevalence rates of dyslipidemia, high cholesterol, high LDL-C, hypertriglyceridemia and mixed type hyperlipidemia exhibited decline trend in vitamin D deficiency, insufficiency and sufficiency groups. The correlation coefficients in between TC and 25OHD, LDL-C and 25OHD, TG and 25OHD were -0.033, -0.022, -0.044, respectively. Low 25OHD levels were associated with the risk of onset of dyslipidemia [OR 1.225 (95% CI 1.075-1.397), p=0.002] in the logistical regression analyses. Conclusions: Deficient serum 25OHD is associated with higher TC, LDL-C, and TG in middle-aged and elderly Chinese individuals. These findings suggest that low 25OHD levels observationally is simply a marker for elevated atherogenic lipoproteins and question a role for vitamin D supplementation in the prevention of cardiovascular disease.
