N1 - Funding Information:
The research leading to these results has received funding from the Health Effects Institute (project “Comparison of long-term air pollution exposure assessment based on mobile monitoring, low-cost sensors, dispersion modelling and routine monitoring-based models”, HEI Research Agreement Number: 4973-RFA19-1/20 -). The PIAMA study was supported by funds from The Netherlands Organization for Health Research and Development; The Netherlands Organization for Scientific Research; The Netherlands Asthma Fund; The Netherlands Ministry of Spatial Planning, Housing, and the Environment; The Netherlands Ministry of Health, Welfare, and Sport; and the National Institute for Public Health and the Environment. The modeling of the UFP concentrations was supported by an ASPASIA grant from the Dutch Research Council ( NWO ) to Dr. Ulrike Gehring (project number 015.010.044), the Environmental Defense Fund, EXPOSOME-NL ( NWO grant number 024.004.017 ) and EXPANSE ( EU-H2020 Grant number 874627 ).

N2 - BACKGROUND: Few epidemiological studies so far have investigated the role of long-term exposure to ultrafine particles (UFP) in inhalant and food allergy development.OBJECTIVES: The purpose of this study was to assess the association between UFP exposure and allergic sensitization to inhalant and food allergens in children up to 16 years old in the Netherlands.METHODS: 2295 participants of a prospective birth cohort with IgE measurements to common inhalant and food allergens at ages 4, 8, 12 and/or 16 were included in the study. Annual average UFP concentrations were estimated for the home addresses at birth and at the time of the IgE measurements using land-use regression models. Generalized estimating equations were used for the assessment of overall and age-specific associations between UFP exposure and allergic sensitization. Additionally, single- and two-pollutant models with NO

RESULTS: We found no significant associations between UFP exposure and allergic sensitization to inhalant and food allergens (OR (95% CI) ranging from 1.02 (0.95-1.10) to 1.05 (0.98-1.12), per IQR increment). NO
