Respiratory and allergic outcomes among 5-year-old children exposed to pesticides

• Background: Little is known about the effects of pesticides on children's respiratory and allergic outcomes.We evaluated associations of prenatal and current pesticide exposures with respiratory and allergic outcomes in children from the Infants' Environmental Health Study in Costa Rica.Methods: Among 5-year-old children (n=303), we measured prenatal and current specific gravity-corrected urinary metabolite concentrations of insecticides (chlorpyrifos, pyrethroids), fungicides (mancozeb, pyrimethanil, thiabendazole) and 2,4-D.We collected information from caregivers on respiratory (ever doctor-diagnosed asthma and lower respiratory tract infections (LRTI), wheeze and cough during last 12 months) and allergic (nasal allergies, itchy rash, ever eczema) outcomes.We fitted separate multivariable logistic regression models for high (≥75th percentile (P75)) vs low (
