Researchers have found an apparent link between excessive television viewing and tobacco use

Children who watch excessive television are at a greater risk of tobacco use and gambling problems in adulthood, according to a new study from the University of Otago.

The New Zealand research team worked out how television viewing in childhood
was related to the risk of having a substance use disorder later in life.

Dr Helena McAnally said excessive time spent in front of the television between the age of five and 15, may be a risk factor for the development of later disorders.

“People often talk of television viewing as an addiction; this research indicates that, for some
people, television viewing may be an early expression of an addictive disorder or may lead to later substance-related and other addictive disorders.”

The study found for tobacco and gambling, the associations were independent of other potential influences like sex, socioeconomic status, and measures of childhood self-control.

Professor Bob Hancox, who worked on the study, said television time has been linked with a range of poorer choice in adulthood.

“Public health agencies have put great effort into advocating for safer alcohol use and safe sexual practices; similar campaigns could be used to advocate for safe screen use,” he explained.

Professor Hancox added this research is among the first to assess how a common, but potentially addictive behaviour can be linked t substance disorders later in life.

“The study highlights the potential need for guidance on digital health and wellbeing,” he said.

The U.S. Academy of Pediatrics’ has recommended a limit of two hours of screen time per day.

They also encourage parents to avoid using screens as pacifiers, babysitters, or to stop tantrums.

It is also recommended screens are turned out at least 30 minutes before bedtime.
