Sex difference in the association between pyrethroids exposure and sleep problems among adolescents: NHANES 2007–2014

Abstract

BackgroundPyrethroids have been widely used in the United States and worldwide. Few studies examined the effect of pyrethroids exposure on sleep problems among adolescents.ObjectivesThis study investigated the associations between pyrethroids exposure and sleep problems in male and female adolescents.MethodsThe data were used from the National Health and Nutrition Examination Survey 2007–2014. In this study, 3-Phenoxybenzoic Acid (3-PBA) was used as a validated biomarker for pyrethroids exposure. The association between urinary 3-PBA and sleep problems was analyzed using logistic regression models.ResultsA total of 805 adolescents aged 16–20 years old were included in this study. The proportion of sleep problems was higher in females than in males (10.18% vs.7.35%, P = 0.154). A significant interaction was found between sex and 3-PBA (P interaction = 0.021) in the risk of sleep problems. A positive association of 3-PBA exposure with sleep problems was observed in male adolescents after adjusting for all the other covariates (OR = 4.04, 95% CI 1.31, 12.42). No statistically significant association was observed in female adolescents.ConclusionsA positive association was observed between pyrethroids exposure and sleep problems in male adolescents, but not in female adolescents. More studies are required to confirm our findings.
