Abstract :

This cross-sectional study included 300 subjects aged 40 years or more, lived in Houli for more than 5 years. Houli has a municipal waste incinerator and a large electric arc furnace factory. They are considered to be the major emission sources of dioxin (PCDD/Fs). Previous epidemiological studies have shown that the relationship between exposure to PCDD/Fs and prevalence of Metabolic Syndrome (MS) is inconsistence. The purpose of this study is to evaluate the relationship between the levels of serum PCDD/Fs of the residents and the prevalence of MS. The health examination and questionnaire survey were conducted. Blood samples and urine samples were collected to determine serum PCDD/Fs and urinary 8-OHdG. In this study, the average plasma PCDD/Fs concentration of 300 subjects was 24.0 pg WHO2005-TEQ/g-lipid, which was higher than the level of non-occupational subjects in Taiwan. The burden of PCDD/Fs of serum PCDD/Fs was not associated with the prevalence of MS. However, the level of serum PCDD/Fs had a significant association with hyperglycemia. The third quartile of PCDDs, PCDFs and total PCDD/Fs were higher than the respective reference groups by 2.69, 2.17-2.29 timesÔ?? higher risk of hyperglycemia. It suggested that exposure to PCDD/Fs is a risk factor for hyperglycemia. In addition, the results of this study showed that there was significantly increased trend for levels of urinary 8-OHdG as PCDFs exposure level increased. Our study supported the hypothesis that exposure to dioxin may cause the oxidative damage to DNA.
