Background:In developed countries sedentary lifestyle is becoming an ever worsening problem. This sedentary lifestyle includes TV watching and general lack of activity. Childhood obesity is on the rise and is reaching epidemic levels. Specifically concerning, is a possible link between TV watching as youth and subsequent asthma development. There are some theories about the mechanism of asthma development related to prolonged periods of youth TV watching. It is thought that TV viewing induces a depressed respiratory rate which, over time, can lead to permanent lung damage. This damage triggers development or worsening of asthma in later years.

Methods: Exhaustive search of available medical literature of MEDLINE-PubMed, CINAHL, and MEDLINE-Ovid was conducting using the keywords television, asthma, eczema, atopic disease, sedentary, lifestyle, andyouth. Studies were evaluated for quality using GRADE criteria.

Results:There is an association between screen time, lifestyle and presence or development of asthma in children. There is evidence to show that it is not due solely to a lack of physical activity but could be directly associated with TV viewing at a young age.

Conclusion:Longer duration of television viewing is associated with a more sedentary lifestyle and a worsening and/or development of asthma and atopic disease. The studies relied on subjective data and more research should be conducted. However, clinicians should educate parents of young children about the possible harms of too much TV watching.
