A web-and Mobile Phone-based Intervention in 4-year-olds: a Population-based Randomized Controlled Trial

Parents in the intervention group receive a six month mHealth program (the MINISTOP app) based on social cognitive theory with strategies to change unhealthy diet and physical activity behaviors. The program includes information, advice, and strategies to change unhealty behaviours and the possibility to register the child's intake of fruits, vegetables, candy, sweetened beverages, moderate-to-vigorous physical activity, and sedentary time. Feedback is then provided on reported variables. In addition, the parents are able to ask questions through the app to a dietician and a psychologist.
