This divergence in FENO50–age trajectories coincides with puberty. Males with higher starting BMI percentile had attenuated FENO50–age slopes. Among males, FENO50 levels were lower in non-Hispanic white subjects. Among both sexes, participants with rhinitis had higher FENO50. FENO50 levels within individuals tracked over time; however, there was considerable variation in FENO50 patterns across participants.FENO50 trajectories from longitudinal data provide evidence of sex differences coinciding with puberty, suggesting potential hormone link. Improved understanding of determinants of FENO50 trajectories is needed to realise the potential for using individualised predicted FENO50 trajectories.Longitudinal FENO50 trajectories in healthy children aged 8–16 years displayed a similar upward trend in males and females until age 11.5, after which males had higher FENO50. Males with higher starting BMI percentile had attenuated FENO50 slopes with age. https://bit.ly/2UMb8mI
