mous. With the increase in 5G network coverage the potential to use gamification increases many times. The mobile applications can not only be used to deliver health- related messages and the physical activity components of any of the programs but can also be used to collect, compile, analyze and access the data easily at the click of the button. The major setback in PICTs is the lack of availability of childhood obesity preva- lence data which to some extend can be solved by using the appropriate mobile applications in a skilled way. The recommendation for future research involves the use of longitudinal studies by using large samples which can clearly show the effect of using gamification to enhance intrinsically motivated behavior. The mobile games used in different parts of the world need to be tailor-made to different regions as the availability and preparation of the food items are different in different places.
