BackgroundRecent studies have shown some alarming
facts about physical fitness among today's teens.
Most teens spend at least 30 hours in a week watching TV and playing computer.
Nearly fifty percent of the teens do not do
any sort of physical activity on a regular basis.
BackgroundInternet and computer use are increasingly
common leisure-time sedentary behaviors, which have the potential to impact negatively on health outcomes.
However, little is known about the extent to which teens’ Internet and computer use is associated with the time spent in leisure-time physical activity.
Research question
Do the teenagers who spend more than 3 hours with a computer have a lack of physical activity?
AimsTo determine how many hours an average
teenager spends on computer
To determine the level of physical activity among teenagers
To examine associations of leisure-time Internet and computer usage with physical activity.
SignificanceAfter completing this research we will
have evidence if excessive computer usage influences the physical activity of a teenager.
The research results will give the background for further studies.
