the recommended levels of PA. The iEngage program targeted health education, PA-related skills and nutrition guidelines focusing on the sugar con- tent of the foods and the recommended level of sugar consumption. The applica- tion consisted of 8 modules each of which was of one hour's duration. Each module consisted of learning activities, quizzes, and short two to five minute PA sessions that generally focused on a specific series of body movements: sprints, jumping, running, walking, squats, or push-ups. The PA was captured by the Misfit activity tracker and sent to the child via the Misfit app through the iEngage modules to maintain learning and offer help in self-assessing accomplishment against personal goals. At the end of each module, the players were guided to set up their aim for the next module. At the end of each module, the player needed to assess if he had achieved the aim which he set at the start of the module. The players were assigned to groups consisting of five players each. The group scored the points if all the members achieved their set goals in their respective modules. The results showed an overall increase of PA during the program, mainly in the less active adolescents who increased their daily steps and there was better adherence to the recommended levels of PA. Veatupu and his colleagues had conducted a study in Tonga called Me' akai in Tonga by using wearable cameras. These wearable kids' cameras were worn around the neck by randomly selected children between the ages of 10 to 12 years. The study used kids' cameras to study the nature and context of the Me'akai (food) eaten by Tongan children with the help of the pictures taken by the children during three consecutive days when they were wearing these cameras (autographer). The photos taken by these wearable cameras helped to provide a large amount of information regarding the food consumed by these children, for example, the number of meals and snacks consumed by the children, the composition of the meals, food types, the portion size
