Introduction: Water chlorination is a cornerstone for enteric diseases control; however, it could also lead to disinfection-by-products formation, which may damage the respiratory epithelium. This study aims to assess association of residual chlorine levels in household water with respiratory symptoms and diarrhea in Peruvian children under 5 years old. Methods: Cross-sectional study using data from the Demographic and Family Health Survey (ENDES) from 2015 to 2019. Subjects were children under 5 years old who had their household water tested for residual chlorine levels. Association with respiratory symptoms without fever, respiratory symptoms with fever, and diarrhea were assessed using crude and adjusted prevalence ratios (aPR) employing Poisson regression adjusted per complex sampling. Results: 95631 children were included, 51.2% males. Prevalence of respiratory symptoms without fever was 19.4%, respiratory symptoms with fever 14.7%, and diarrhea 11.6%. Households with residual chlorine levels ≥0.5 mg/L were 30.5%; and 54.6% had non-detectable levels. Levels ≥0.5 mg/L were associated with higher prevalence of respiratory symptoms without fever (aPR 1.09; 95%CI 1.03–1.15) and less diarrhea (aPR 0.90; 95%CI 0.84–0.96). Levels 0.1-0.5mg/L were associated with higher prevalence of respiratory symptoms without fever (aPR 1.10; 95%CI 1.04–1.16) and less diarrhea (aPR 0.89; 95%IC95 0.83–0.96). There was no association with respiratory symptoms with fever. Conclusions: Residual chlorine levels ≥0.5 mg/L and between 0.1-0.5 mg/L were associated with higher prevalence of respiratory symptoms without fever, and with less prevalence of diarrhea, but not with respiratory symptoms accompanied by fever. Relationship between household water chlorination and airway irritation in children should be further explored.
