Including family involvement as part of a multi-component pediatric weight management intervention is highly consistent with positive weight status outcomes. Multi-component pediatric weight management interventions that include family involvement were consistent with positive weight status outcomes at both six and 12 months.

• Grade I means there is Good/Strong evidence supporting the statement;
• Grade II is Fair;
• Grade III is Limited/Weak;
• Grade IV is Expert Opinion Only;
• Grade V is Not Assignable.
• High (A) means we are very confident that the true effect lies close to that of the estimate of the effect;
• Moderate (B) means we are moderately confident in the effect estimate;
• Low (C) means our confidence in the effect estimate is limited;
• Very Low (D) means we have very little confidence in the effect estimate.
• Ungraded means a grade is not assignable.

Multi-component intensive weight management interventions in the clinic setting that were at least six months in length, included group pediatric weight management sessions and were not focused exclusively on teens, were consistently associated with positive weight status outcomes at 12 months. Shorter-term (less than six months) interventions were not consistently associated with positive weight status at 12 months.

The clinic setting was consistently associated with positive weight status at six months, when pediatric weight management consisted of one of the following conditions:  

• Multi-component intensive interventions in group pediatric weight management sessions for at least six months that included family involvement
• Non-intensive interventions in individual pediatric weight management sessions for less than six months that did not focus exclusively on teens.

The clinic setting was consistently associated with positive weight status at 12 months, when pediatric weight management consisted of one of the following conditions:  

• Multi-component intensive interventions in group sessions for at least six months that did not focus exclusively on teens
• Multi-component intensive interventions in group sessions that included family involvement and focused exclusively on teens.  

Pediatric weight management outside a clinic setting was associated with positive weight status outcomes at 12 months in multi-component intensive interventions in group sessions that included family involvement and focused exclusively on teens.

Multi-component intensive interventions that included group pediatric weight management sessions and family participation were consistently associated with shorter-term (six months) and longer-term (12 months) positive weight status outcomes. Treatment interventions that relied exclusively on individual pediatric weight management sessions, with or without family participation, were associated with shorter-term positive weight status outcomes. Further research is needed regarding individual sessions and long-term weight status outcomes.
