Background: Exposure of children and adolescents to endocrine disrupting chemicals (EDCs) causes the development of non-communicable diseases. Triclosan (TCS) is a fat-soluble antimicrobial agent, and methyl-triclosan (MTCS) is the predominant metabolite of TCS. The increasing use of consumables TCS (toothpaste, mouthwash, personal care products) in human has raised concerns about human health. Methods: The urinary concentrations of TCS and MTCS were measured by GC/MS. Lipid profiles (TG, TC, LDL, and HDL), anthropometric parameters (WC, BMI z-score, and BMI), FBS, SBP, and DBP tests were performed on 79 children and adolescents. Results: Of 79 people included as the study population, 42 subjects (53.16%) were males. Most of the study population as 32 subjects (40.50%) were obese. The mean concentrations of TCS and MTCS in the obese population were 5.47 ± 2.99 and 2.32 ± 1.04 µg/L, respectively. After adjusting for possible confounding factors, the results showed that a one-unit increase in DBP caused a 0.03 units increase in TCS levels in male subjects (P=0.01). A one-unit increase in DBP also caused a 0.02 units increase in MTCS (P=0.001). There was a significant relationship between TCS and HDL (OR=0.90, P=0.005), LDL (OR=1.13, P=0.01), and TG (OR =1.05, P<0.0001). There was also a significant relationship between MTCS and HDL (OR=0.88, P=0.001), LDL (OR=1.03, P=0.009), and TG (OR=1.04, P < 0.0001). Conclusion: According to the results, there is a relationship between TCS, MTCS, and predictive indicators of cardiovascular diseases and obesity.
