Short-term exposure to relative humidity and lung health in early adolescents.

ABSTRACT:

Background

Extremes in humidity can induce bronchoconstriction and trigger breathing symptoms in people with asthma. Less is known about how humidity influences measurements of lung health in children and adolescents. Our objective was to assess the extent to which short-term exposures to high and low relative humidity (RH) are associated with lung function and fractional exhaled nitric oxide (FeNO) in adolescents.

Methods

We included adolescents (mean age 13.2 y, SD: 0.9) from a northeast US prospective prebirth cohort (n = 1019). We assigned daily RH levels to geocoded participant addresses. We defined low or high RH as ≤10^th or ≥90^th internal percentiles, respectively, of the cohort-specific RH distribution and the reference RH as the median. We eval
