The More & Less Study: A Trial Testing Different Treatment Approaches to Obesity in Preschoolers (M&L)

Obesity has been shown to be resistant to treatment in adults, adolescents, and in school age children, but not during early childhood. Yet knowledge on the effectiveness of early childhood treatment programs for obesity is still very limited, preventing the widespread implementation of such programs. The overarching purpose of this study is to evaluate the effectiveness of early treatment of childhood obesity. The investigators plan to perform a carefully-designed randomized controlled trial that will evaluate different treatment options offered to families with children with obesity, organized within the healthcare system and followed up for at least 1 year post-baseline. Participants will be children aged 4-6 years (N=180) with obesity and their parents. This study will facilitate a close examination of key treatment components and mechanisms of change. Results from this study will lead to better healthcare options for obesity treatment during childhood and ultimately to the prevention of obesity later in life from a public health perspective.
