Abstract

Objective: To test cross-sectional associations between urinary concentrations of 2,5-dichlorophenol (2,5-DCP) and 2,4-dichlorophenol (2,4-DCP) with the prevalence of cardiovascular disease (CVD), cancer, lung disease, thyroid problems and liver conditions. Methods: Logistic regression was used to evaluate associations of urinary concentrations of 2,5-DCP and 2,4-DCP with prevalence of various medical conditions among 3617 National Health and Nutrition Examination Survey participants from 2007-2008 and 2009-2010. ORs and 95% CIs for each disease were estimated. All regression models were adjusted for urinary creatinine. Results: We observed a monotonically increasing association between quartiles of 2,5-DCP and prevalence of CVD. After adjustment for sociodemographic and lifestyle characteristics, participants with the highest versus lowest quartile of urinary 2,5-DCP had an OR=1.84 (95% CI 1.26 to 2.70) (p linear trend=0.006). The association was similar with further adjustment for established clinical CVD risk factors. Higher 2,5-DCP was also associated with prevalence of all cancers combined (OR Q4 vs Q1 =1.50 (95% CI 1.00 to 2.26); p trend=0.05) and, in exploratory analyses, with gynaecological cancers (OR Q4 vs Q1 =4.15 (95% CI 1.51 to 11.40; p trend=0.01)). No associations were detected between 2,5-DCP and lung diseases, thyroid problems or liver conditions, nor between 2,4-DCP and prevalent disease. Conclusion: In this nationally representative study, higher urinary 2,5-DCP concentrations were associated with greater prevalence of CVD and all cancers combined. Further examination may be warranted to assess whether chronic exposure to 2,5-DCP is associated with incidence of adverse health outcomes.
