STOMP Early Years: A Pilot RCT of an Intensive, Family-Centred, Home Visiting Intervention for Young Children With Severe Obesity (STOMP)

This internal pilot study will determine whether a highly promising primary care based intervention that combines group based parenting skills training and public health nurse home visits with a focus on healthy nutrition, activity and sleep, will lead to improved weight status in 1 to 5 year old children with severe obesity.

Children with severe obesity will be identified through the obesity management clinical program at The Hospital for Sick Children called STOMP (SickKids Team Obesity Management Program). The STOMP Early Years Program is a unique and intensive, paediatric obesity management program designed for 1 to 5 year-olds with severe obesity and their families. Families who participate in this study will be randomly assigned (having an equal chance of being in either group) to one of the two study groups that will run for 6 months:

Group A: Ten weeks of group parenting education sessions with 2-4 public health nurse home visits and four one-on-one check-ins with an interdisciplinary team at STOMP.

Group B: Wait listed to receive parenting education sessions; receive one-on-one checks with an interdisciplinary team at STOMP.

In addition to the measures collected as part of STOMP, families will complete the following questionnaires before the start of the trial, and after 6 months:

Parenting Scale, Parenting Stress Index, Depression, Anxiety, and Stress Scale (DASS-21), Cost Questionnaire, and Children's Behaviour Questionnaire (CBQ).
