The association of vitamin D status and dietary calcium intake with individual components of the metabolic syndrome: a population-based study in Victoria, Australia.

Abstract

This study examined the associations between 25-hydroxyvitamin D (25-OHD), dietary calcium (Ca) intake, and individual components of the metabolic syndrome (MetS). Methods: We analyzed a population-based sample of 18-75-year-old adults (n=3387) from the Victorian Health Monitor survey. Results: After adjustment for sociodemographic, physical, and dietary factors, as well as other MetS components, every 10 nmol/l increment in 25-OHD was associated with reduced adjusted odds ratio (AOR) of elevated triglycerides (TG) [AOR: 0.79, 95% confidence interval (CI): 0.74-0.84, P<0.001], and higher fasting plasma glucose (AOR: 0.91, 95% CI: 0.86-0.96, P=0.002). After adjustment for confounders, every 5..
