Children with a maternal history of allergic rhinitis and belonging to specific BMI trajectories require close monitoring, as these children may be at higher risk for developing allergic rhinitis at age 18 years or even earlier.  The latest study by Chia-Lun Chang from The Centre for Epidemiology and Biostatistics, and Adrian J. Lowe, a principal research fellow in allergic disease and epidemiology, and their colleagues, found that  infants with early-low and catch-up or below-average BMI growth, along with a mother with allergic rhinitis had a significantly increased risk for allergic rhinitis by age 18 years. The findings of the study, published in Pediatric Allergy and Immunology, suggested that BMI trajectories in the first 2 years of life influence the risk for asthma, though it was unclear whether these trajectories were also associated with eczema and food allergies.
