摘要：Objectives This study aimed to evaluate the association between presence of depression symptoms and the exposure level to insecticides among aged population in rural area,determined via measured levels of urinary 3-phenoxybenzoic acid (3-PBA),after controlling for socioeconomic confounding factors. Methods Using a cross-sectional study design,we randomly recruited participants for our study (161 male and 239 female) from rural areas of Asan,Chungnam,Korea. Environmental risk factor exposure was assessed using a questionnaire,and gas chromatography-mass spectrometry was used to analyze urinary 3-PBA levels. We used a logistic regression analysis to assess the association of urinary 3-PBA levels with the presence of self-reported depression symptoms. Results After controlling for creatinine levels,the median (interquartile range) concentration of 3-PBA was approximately 1.5 times (p<0.05) higher among female (1.54 [0.90 to 2.35]) μg/g) than among male (1.06 [0.64 to 1.81] μg/g). Our study found that among female participants,the unit increase in 3-PBA levels exhibited a likely positive association (odds ratio,1.12;95% confidence interval,1.00 to 1.25) with an increased risk of presence of self-reported depression symptoms,after adjusting for socioeconomic insurance type,daily physical condition,marital status,smoking status,and age. Conclusions Given our finding of a potential association between the presence of selfreported depression symptoms and 3-PBA levels,precautions should be considered to minimize exposure to insecticides and thus protect the health of aged residents in rural areas.
