Abstract:
Metabolic syndrome is a major risk factor of cardiovascular disease and type 2 Diabetes mellitus. Many studies found the relationship between metabolic syndrome and heavy metals in human body, especially Arsenic. No clearly study about the relationship of metabolic syndrome and Arsenic in Thailand. This study aim to compare the different of total urine arsenic between the metabolic syndrome and without metabolic syndrome subjects in Thailand and to study the correlation between total urine arsenic and metabolic syndrome components. The cross-sectional, retrospective descriptive study was conducted. The subjects who participated in health examination at the check-up and Anti-aging department during the period of 1st January 2007 to 31st March 2015 and completed the research's criteria were enrolled. All data collected from 5 medical centers in Bangkok and others province of Thailand during 1st January 2015 to 31st March 2015. The metabolic syndrome diagnostic criteria was defined using the modified Harmonizing the Metabolic Syndrome by six international expert groups. A total 192 subjects (79 men and 113 women), age 20 to 80 years were enrolled in this study. Results showed that the subject of 71 (36.98 %) and 121 (63.02%) persons were diagnosed metabolic syndrome and without metabolic syndrome,respectively.
The median (± interquartile range) of the total urine arsenic of metabolic syndrome group and without metabolic syndrome group were 23.47±58.35 μg/L and 23.88±39.07 μg/L, respectively. There were no significant different between 2 groups (P-value = 0.6436). No correlation was found between total urine arsenic and metabolic syndrome components (P-value > 0.05). The comparison of the median of total urine arsenic level in each percentile range of all personal and clinical data showed that men, Bangkok residents and hyperlipidemia group were significantly higher than women, non Bangkok residents and without hyperlipidemia group, respectively (P-value < 0.001, 0.012 and 0.0226, respectively). We also found systolic blood pressure and LDL cholesterol level were significantly higher in the subjects who had the total urine arsenic level ≥ 55 μg/L than the lower groups (P-value = 0.0237 and 0.0223, respectively).
In conclusion, no significant different of total urine arsenic level between metabolic syndrome and without metabolic syndrome groups. The present study not found a correlation between total urine arsenic and metabolic syndrome components. However, we found the level of total urine arsenic (≥ 55 μg/L) that associated with higher systolic blood pressure and LDL cholesterol.
