Acceptability of Robotic-Assisted Exercise Coaching Among Diverse Youth: Pilot Study

A social robot-based platform for health behavior change toward prevention of childhood obesity

Childhood obesity is a major public health challenge which is linked with the occurrence of diseases such as diabetes and cancer. The COVID-19 pandemic has forced changes to the lifestyle behaviors of children, thereby making the risk of developing obesity even greater. Novel preventive tools and approaches are required to fight childhood obesity. We present a social robot-based platform which utilizes an interactive motivational strategy in communication with children, collects self-reports through the touch of tangible objects, and processes behavioral data, aiming to: (a) screen and assess the behaviors of children in the dimensions of physical activity, diet, and education, and (b) recommend individualized goals for health behavior change. The platform was integrated through a microservice architecture within a multi-component system targeting childhood obesity prevention. The platform was evaluated in an experimental study with 30 children aged 9-12 years in a real-life school setting, showing children's acceptance to use it, and an 80% success rate in achieving weekly personal health goals recommended by the social robot-based platform. The results provide preliminary evidence on the implementation feasibility and potential of the social robot-based platform toward the betterment of children's health behaviors in the context of childhood obesity prevention. Further rigorous longer-term studies are required.

New Technologies for Promoting Physical Activity in Healthy Children and in Children with Chronic Respiratory Diseases: A Narrative Review

Physical activity (PA) is proven to benefit children and adolescents in several ways. New technologies may provide children with stimulating modalities for organizing their leisure time, accessing fitness programs, and obtaining daily goal reminders and peer support. Due to the current COVID-19 pandemic, following WHO recommendations for PA is difficult for many children, especially for those living in urban areas. Therefore, the use of digital tools to support and maintain PA could be useful in healthy children, as well as in those with chronic respiratory diseases (CRDs). This narrative review aims to summarize the most recent evidence about the role of new technologies in promoting PA in healthy children and in those with CRDs, in supporting PA during the COVID-19 pandemic, and in enhancing psychological wellbeing in this age group. The use of technological devices for promoting PA, such as web/mobile apps and games, has been proven to be effective both in healthy children and in those with CRDs. In conclusion, new technologies are very promising in terms of feasibility, acceptability, and efficacy in promoting PA. Further studies are required to evaluate the long-term health benefits of using these technologies.
