Association between Urinary Phthalate Metabolite Concentration and Atopic Dermatitis in Korean Adolescents Participating in the Third Korean National Environmental Health Survey, 2015-2017

초록

Previous studies have highlighted the potential health effects of phthalate exposure, such as atopic dermatitis and asthma. However, evidence supporting the association between phthalate exposure and atopic dermatitis is limited and based on data collected from Western populations. This study aimed to analyze the association between phthalate exposure and atopic dermatitis in Korean adolescents aged 12-17 years using a nationally representative dataset. We conducted a cross-sectional study using a publicly available dataset from the third Korean National Environmental Health Survey (n = 797). We divided the study participants into four quartiles according to urinary phthalate metabolite concentrations. The odds ratio of having atopic dermatitis was calculated using the first quartile as the reference group in binary logistic regression. We found that in the logistic regression model, both the urinary Mono-(2-ethyl-5-carboxypentyl) phthalate (MECCP; OR: 1.81; CI: 1.01-3.25) and Mono-benzyl phthalate (MBzP; OR: 1.81; CI: 1.01-3.25) concentrations in the highest quartile were positively associated with atopic dermatitis. The atopic dermatitis group had a significantly higher mean urinary MECCP and MBzP concentration. In the future, longitudinal studies involving repeated measurements are warranted to analyze the long-term effects of phthalate.
