Parental involvement in interventions appears to be important. The use of eHealth modalities in interventions also seems to be promising. To our knowledge, there have been no previous reviews that have specifically investigated the effectiveness of parent-focused eHealth obesity interventions, a gap that this systematic review and meta-analysis intends to address.<h4>Objective</h4>The objective of this study was to review the evidence for body mass index (BMI)/BMI z-score improvements in eHealth overweight and obesity randomized controlled trials for children and adolescents, where parents or carers were an agent of change.<hJournal of medical Internet researche203https://www.ebi.ac.uk/biostudies/studies/S-EPMC4974451biostudies-literatureParent-Focused Childhood and Adolescent Overweight and Obesity eHealth Interventions: A Systematic Review and Meta-Analysis.PMC4974451Okely ADJones RAHammersley MLfalseParent-Focused Childhood and Adolescent Overweight and Obesity eHealth Interventions: A Systematic Review and Meta-Analysis.<h4>Background</h4>Effective broad-reach interventions to reduce childhood obesity are needed, but there is currently little consensus on the most effective approach.
