A systematic review and meta-analysis examining parent-involved digital health interventions is indexed on PubMed.[^1] The entry was current as of 30 October 2026.

The work appears in the Journal of Medical Internet Research. It analysed data from a total sample of 4156 participants.

Primary outcomes for the review were adiposity related measures including BMI. Secondary outcomes included dietary behaviour, physical activity and sedentary behaviour.

Authors reported parent-involved digital health interventions produced a small but statistically significant reduction in BMI related outcomes compared with controls. The pooled standardised mean difference was -0.11, 95% CI -0.19 to -0.04, P=.004.

When results were stratified by control type, the effect remained significant for trials using inactive controls. No statistically significant effect was detected in trials using active controls.
