Prenatal Air Pollution Exposure During Late Pregnancy Associates With Food Sensitization at 18 Months

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.
