Young & Active: development and evaluation of an internet intervention to increase fitness and health-related quality of life in adolescents with overweight and obesity
MetadataShow full item record
Overweight and obesity among adolescents may have consequences with potentially lasting effects on health and health-related quality of life (HRQoL). Excess weight is also associated with decreases in physical activity and cardiorespiratory fitness (CRF). Research presenting effective interventions for prevention and treatment of overweight and obesity in adolescents is limited. Internet interventions may provide opportunities for low threshold counseling using feedback to guide and support health behavior, including increased physical activity (PA). The overall aim of the present study was to develop and evaluate an Internet intervention for motivating overweight and obese adolescents to increase and maintain self-determined physical PA and thereby enhance their CRF and HRQoL.Paper I: Riiser K, Løndal K, Ommundsen Y, Sundar T, Helseth S (2013) Development and usability testing of an Internet intervention to increase physical activity in overweight adolescents.
