We aimed to assess, whether physical activity differs between children with and without asthma symptoms.Methods: In a population-based cohort, we collected information on physical activity and respiratory symptoms (wheeze, cough without colds, night cough) by questionnaire at ages 4-8 (N= 5212) and 6-10 years (N=4236). We compared prevalence of symptoms between inactive (0-1 hour/day of outdoor play) and active (≥2 hours/day) children.Results: At age 4-8, 4447 children (85%) were active, at age 6-10, 3686 (87%). In 4-8 years olds, 17% of active and 19% of inactive children had current wheeze (p=0.139), 38% vs. 41% had cough without colds (p=0.142), 27% vs. 33% had cough at night (p=0.003), 12% vs. 12% had moderate wheeze needing inhaler treatment (p=0.565). In 6-10 year olds, 15% of active vs. 16% of inactive children had current wheeze (p=0.636), 36% vs. 40% had cough without colds (p=0.066), 25% vs. 30% had cough at night (p=0.008), and 10% in both groups had wheeze necessitating treatment (p=0.701).Conclusions: Physical activity levels were comparable between children with and without asthma related symptoms, with small differences only seen mainly for cough at night. Further analysis will investigate whether this is due to insufficient asthma treatment, and determine potential long-term effects of physical activity on prognosis of symptoms and lung function.
