Implementation of Combined Lifestyle Interventions for Children with Overweight or Obesity: Experiences of Healthcare Professionals in Multiple Communities.

Background: To counteract children with obesity, different protocols for combined lifestyle interventions (CLIs) are implemented by healthcare providers (HCPs). To understand the effects of CLI, we studied the implementation process, facilitators and barriers experienced by HCPs.

Methods: A multiple case study design in which community-based CLIs (n = 4), implemented in a total of ten different communities, are conceptualized as a "case".
