Ali GB, Bui DS, Lodge CJ, et al. - Utilizing data from the Melbourne Atopy Cohort Study, researchers, for the first time, examined the connections between body mass index (BMI) trajectories in the first 2 years of life, and adolescent asthma and lung function. In total, 620 infants with a family history of allergic diseases were enlisted by recruiting pregnant women and their families from 1990 to 1994 from Melbourne, Australia. Five BMI trajectories have been identified. The trajectories of "early low & catch up" and "persistently high" were linked to asthma and obstructive lung function pattern in adolescence. A restrictive pattern was linked to having a persistently low BMI at an early age. As a result, maintaining normal growth patterns can benefit adolescent respiratory health.
