The effect of physical activity on asthma incidence over 10 years: population-based study
Abstract
Asthma remains a common disease around the world, with global estimates indicating that 4.3% of adults have doctor-diagnosed asthma [1]. Physical activity has been found to improve asthma outcomes in adults with asthma [2, 3]. While it has been hypothesised that physical activity could also reduce asthma incidence through a variety of mechanisms, studies to date have provided mixed results. Some studies find that physical activity reduces the incidence of asthma [4, 5], yet others find no evidence for a reduction in risk [6, 7]. These inconsistent findings could be partly attributed to variation in the definition of incident asthma, which is mostly restricted to self-reported asthma outcomes. In this analysis, we investigated the association between (frequency and duration of) vigorous physical activity and asthma incidence over 10 years, using the European Community Respiratory Health Survey (ECRHS), considering multiple asthma-related outcomes in an initially asthma-free population.
