Overactive bladder (OAB) is a group of clinical symptoms that are highly bothersome to the life and spirit of patients. However, little is known about the role of ubiquitous di-(2-ethylhexyl) phthalate (DEHP) exposure in the disorder. Hence, the study was conducted. The data were collected using the 2003–2008 National Health and Nutrition Examination Survey (NHANES) data ( n = 2121), and multiple logistic regression was adapted. The concentrations of DEHP (∑DEHP) were calculated for each metabolite and split into quartiles for analysis. After adjusting for confounding factors, ∑DEHP was associated with increased odds of OAB for the highest quartile ( OR = 1.15, 95% CI [1.06, 1.25], p < 0.05), and the highest quartile of metabolites showed similar results, such as mono-(2-ethyl-5-hydroxyhexyl) phthalate ( OR = 1.09, 95% CI [1.01, 1.19], p < 0.05), mono-(2-ethyl-5-oxohexyl) phthalate ( OR = 1.21, 95% CI [1.11, 1.32], p < 0.05) and mono-(2-ethyl-5-carboxypentyl) phthalate ( OR = 1.22, 95% CI [1.12, 1.33], p < 0.05). The association remained when the analyses were stratified by age and sex. Our study adds evidence for understanding the potential role of environmental factors in OAB, and further research is needed to determine whether the status of OAB can be changed by controlling DEHP exposure.
