The Effectiveness of Novel E-Health Applications in the Prevention and Management of Childhood Obesity
Authors' conclusion
These novel e-health applications and digital technologies were effective at collecting and analyzing objective data about the daily behavior of children and adolescents with overweight and obesity. Therefore, they may be useful to use in clinical practice and to design public health policies to address the epidemic of childhood obesity. </p>.
