Abstract
The purpose of this study was to analyse the association between blood heavy metal concentration (lead, mercury, cadmium) and components of metabolic syndrome (Mets) in Korean male adults. Data were extracted from the 5th Korea National Health and Nutrition Examination Survey (KNHANES) 2010. Participants were 965 Korean male adults aged 20 years and over. The data were analysed by using SPSS/Win 20.0. The means of blood lead, mercury and cadmium concentration in participants were 2.94μg/dl, 5.98μg/L, and 1.10μg/L, respectively. The means of Fasting Blood Glucose (FBG), Systolic Blood Pressure (SBP), Diastolic Blood Pressure (DBP), serum Triglyceride (TG), serum High-density Lipoprotein Cholesterol (HDL-C) and Waist Circumference (WC) were 100.23mg/dl, 123.43mmHg, 81.23mmHg, 161.84mg/dl, 49.64mg/dl and 84.35cm, respectively. After adjusting for demographical characteristics (age, education, income, residential area, occupation, drinking, and smoking), increase of FBS and DBP were associated with the serum cadmium (OR = 1.465) and lead (OR = 1.147), respectively. Mercury was associated with increase of WC (OR = 1.051) and Mets (OR = 1.048). Based on the outcomes of this study, it is necessary to develop intervention strategies for reducing the lead, mercury and cadmium exposure and monitor continuous blood heavy metal concentration.
