Abstract
Background: Over 340 million children and adolescents aged 5-19 were overweight or obese in 2016. The fundamental cause of obesity and overweight are an increased intake of energy-dense foods that are high in fat and sugars and an increase in physical inactivity. Television and computer viewing are hypothesized as contributing factors because of their documented role in encouraging consumption of highly advertised foods that may lead to the replacement of fruits and vegetables. This study aimed to systematically review the effectiveness of web-based health promotion on vegetables consumption among children in America, Australia, And Europe.
