Key Points

The study aims to investigate the relationship between prenatal air pollution exposure and food sensitization in infants at 18 months.
Examined associations between air pollution exposure (NO x and PM 2.5) during late pregnancy and food sensitization outcomes at 18 months.
Analyzed trimester-specific effects and the influence of extrinsic and intrinsic factors.
Utilized data from mothers and infants over a defined follow-up period.
Prenatal exposure to NO x correlates with increased food sensitization at 18 months.
Exposure to PM 2.5 is associated with a higher incidence of atopic dermatitis in infants.
Evidence suggests that the impact is influenced by both extrinsic and intrinsic factors during pregnancy.

Implication

Associates prenatal air pollution exposure with food sensitization in infants, suggesting significant developmental impact.

Abstract

Summary Air pollution exposure during development was associated with food sensitization (NO x ) and atopic dermatitis (PM 2.5 ). The associations were trimester‐specific, with evidence of effect modification by extrinsic and intrinsic factors.
