The problem
Intervention: 6-month home-based obesity prevention intervention focused on establishing healthful household routines
Who it was tested with: 285 families with preschool-aged children (384 children, mean age 3.5 ± 1.3 years, 50.3% girls; 20.2% at risk for overweight/obesity, 8.2% with overweight/obesity).
Children or communities are compared with a group that did not receive the intervention, or followed over years. This is the design that best separates what the intervention did from everything else that changed.
"The Guelph Family Health Study is a randomised controlled trial of a 6-month obesity prevention intervention focused on establishing healthful household routines among 285 families with preschool-aged children... No significant group by time interactions were observed, indicating that the intervention had no significant impact on children's eating behaviours compared to controls." The randomised controlled trial design with measurements at baseline, post-intervention, and follow-up, combined with clear reporting of null findings, provides experimental-level evidence that this specific intervention approach did not achieve its intended effect on eating behaviours.
Study relies on parent-reported eating behaviours via questionnaire, which may introduce measurement bias. The intervention focused on household routines rather than explicitly targeting eating behaviours, which the authors suggest may explain the lack of impact on eating behaviour outcomes.
