The data of 16,096 adults (6,840 men as well as 4,916 premenopausal and 4,340 postmenopausal women) aged ≥ 20 years in the Korean National Health and Nutrition Examination Survey (KNHANES) between 2010 and 2012 were analyzed. The prevalence rate of MetS was 3,978 (24.7%) (men, 24.6%; premenopausal women, 11.1%; postmenopausal women, 40.3%). The key study results were as follows: First, after the adjustment for relevant variables, the serum ferritin level (M±SE) was significantly higher (p ＜0.001) in the MetS group (men, 132.25±1.98 ng/mL; premenopausal women, 39.89±1.49 ng/mL; postmenopausal women, 73.45±1.14 ng/mL) than in the non-MetS group (men, 111.08±1.01 ng/mL; premenopausal women, 32.26±0.50 ng/mL; postmenopausal women, 63.26±0.98 ng/mL). Second, the serum ferritin levels increased as MSS increased in all groups (men, premenopausal women, and postmenopausal women) (p＜0.001). In conclusion, MetS and MSS increases were positively associated with higher serum ferritin levels.

The aim of this study was to assess the association of metabolic syndrome (MetS) and vitamin D and urine microalbumin (MA) in Korean adults. The study subjects were Korean adults 20 years or older (n=4,948). A covariance test adjusted for covariates was performed for urine MA levels in relation to vitamin D status (vitamin D deficiency, vitamin D insufficiency, vitamin D sufficiency). The key study results were as follows: First, in subjects without MetS, after adjusting for related variables (age, gender, smoking, drinking, regular exercising, wast measurement, body mass index, total cholesterol, triglycerides, high density lipoprotein cholesterol, fasting blood glucose, and glomerular filtration rate), vitamin D levels were inversely associated with Log-MA levels (p<0.001). Second, in subjects with MetS, after adjusting for related variables, vitamin D levels were not associated with Log-MA levels (p=0.892). In conclusion, vitamin D was inversely associated with urine MA levels in Korean adults without MetS, but not in Korean adults with MetS.■ keyword :|Urine Microalbumin|Vitamin D|25(OH)D|Metabolic Syndrome|
