Young children who spend more than two hours glued to the TV every day double their subsequent risk of developing asthma.
The findings are based on more than 3,000 children whose respiratory health was tracked from birth to 11.5 years of age.
The amount of time spent in front of the box was used as a proxy measure of sedentary behaviour, because personal computers and games consoles were not in widespread use at the time (mid 1990s).
By the time the children were 11.5 years old, there was little difference in levels of sedentary behaviour between those with asthma and those without.
The relationship between physical activity, sedentary behaviour and asthma is complex. Recent research has suggested that breathing patterns in children may be associated with sedentary behaviour, sparking developmental changes in the lungs and subsequent wheezing.
