Association of volatile organic compound exposure and metabolic syndrome.

The cumulative toxicity of volatile organic compounds (VOCs) cause many medical diseases. We analyzed the evidence of association between VOCs and risk of metabolic syndrome in the Korean population using 1771 participants from the 2023 National Health and Nutrition Examination Survey. The creatinine-corrected urinary concentrations of BMA, 2-MHA, PGA, SPMA, 3-HPMA, BPMA and DHBMA were higher in the metabolic syndrome group than in the non-metabolic syndrome group. Urine N-Acetyl-S-(phenyl)-L-cysteine (SPMA) levels were significantly associated with metabolic syndrome after adjusting for confounders (odds ratio: 1.71). 2-MHA (OR 1.29, P=0.035) and SPMA (OR 2.84, P<0.001) were associated with the risk of elevated FBG impairment and SPMA (OR 1.57) was positively connected with the high blood pressure (P=0.016). In conclusion, the findings indicated significant association between the metabolic syndrome and a number of VOCs. Among them, there was a substantial positive correlation between the urinary SPMA levels and metabolic syndrome.
