Modest treatment effects and high program attrition: The impact of interdisciplinary, individualized care for managing paediatric obesity.

Background: There is an urgent need to identify effective weight management interventions in real-world, clinical settings to improve the health of children with obesity.

Objectives: To determine the impact of individualized, interdisciplinary care on the weight status of children with obesity; to assess the relationship between clinical interactions and change in participants' weight status; and to document the degree of program attrition.

Methods: A retrospective medical record review of clinical and administrative data from a paediatric weight management clinic in Edmonton, Alberta, was performed, which included data from a group of five- to 18-year-olds (body mass index [BMI] ≥85th percentile) collected from 2008 to 2012.
