Researchers have found that students who use their smartphones five or more hours a day are prone to higher risk of obesity and likely to have other lifestyle habits that increases the risk of heart disease.
According to a study, researchers analysed 1 060 students (700 girls and 360 boys) of Colombia with an average age of 19 years and 20 years, respectively.
"It is important for the general population to know and be aware that, despite being undoubtedly attractive for its multiple purposes, portability, comfort, access to countless services, information and entertainment sources, mobile technology should also be used to improve habits and healthy behaviours," said study lead Author Mirary Mantilla-Morron from the Simon Bolivar University in Colombia.
The study found that the risk of obesity increases by 43% if a smartphone was used for five or more hours a day, as participating students were twice as likely to drink more sugary drinks, fast food, sweets, snacks and have decreased physical activities.
According to researchers, 26% of the students who were overweight and 4.6% who were obese spent more than five hours using their device.
