Purpose
It has been reported that polycyclic aromatic hydrocarbons (PAHs) exposure was associated with the increasing risk of various diseases. Utilizing the data from the general population of the U.S., we tried to assess the association between PAHs exposure and KS.
Methods
The dataset was extracted from National Health and Nutrition Examination Survey (NHANES) 2007–2016. The hydroxylated metabolites of polycyclic aromatic hydrocarbons (OH-PAHs) were detected as representative of urinary PAHs. Ranking-based PAHs score was used to evaluate the total PAHs exposure burden. Multivariable logistic regression analyses were performed to assess the association between PAHs exposure and KS after adjusting a series of confounding factors.
Results
8975 eligible participants were included. In multivariable logistic regression analyses, after adjusting confounding variables, 2-hydroxynaphthalene (OR 1.38, 1.16–1.65; p = 0.038) and 9-hydroxyfluorene (OR 1.39, 1.06–1.84, p = 0.019) were still observed to have significant positive correlations with the prevalence of KS, respectively. The incidence of KS increased significantly with the increase of total PAHs burden (p for trend = 0.011). Significant interaction effects were observed in the subgroup of gender (p for interaction < 0.05). Among female participants, PAHs exposure was more significantly correlated with KS. Higher 2-hydroxynaphthalene (OR 1.94, 1.39–2.70; p < 0.001), 1-hydroxyphenanthrene (OR 1.57, 1.07–2.30; p = 0.022) and 2-hydroxyphenanthrene (OR 1.85, 1.11–3.06; p = 0.018) were significantly associated with the increased incidence of KS in women.
Conclusions
There is a significant association between a high level of PAHs exposure and increased prevalence of KS. In particular, in the female population, the relationship between PAHs exposure and KS is especially significant.
