TL;DR: Primary analyses demonstrated that behaviour-changing interventions compared to no treatment/usual care control at longest follow-up reduced BMI, BMI z score and weight.

TL;DR: The studies contributing most information to outcomes of weight and body mass index (BMI) were from studies at a low risk of bias, but studies with a highrisk of bias provided data on adverse events and quality of life.

TL;DR: In trials comparing a multicomponent intervention withusual care, enhanced usual care, or information control, a greater reduction in body mass index (BMI) z score is found in the intervention groups at the end of the intervention, but only the dairy-rich diet maintained this at 36 months' follow-up.

TL;DR: The evidence suggests that multi-component behaviour changing interventions may be beneficial in achieving small reductions in body weight status in children of all ages, with low adverse event occurrence were reported.

TL;DR: Parent-only interventions may be an effective treatment option for overweight or obese children aged 5 to 11 years when compared with waiting list controls, and generally, these trials did not show substantial differences between their respective parent-only groups on BMI outcomes.
