Physical activity and asthma development in childhood: Prospective birth cohort study.

Background

Sedentary behavior and decreased physical activity are possible risk factors for developing asthma.

Children who were born prematurely or with congenital defects/diseases with possible influence on either physical activity or respiratory symptoms were excluded. Physical activity, sedentary behavior, and screen time were measured at age 4 to 5 years by questionnaire and accelerometry in a subgroup (n = 301). Primary outcome was asthma, asses
