Summary

The HOT versus COT trial aims to compare the effectiveness of two different lifestyle interventions for treatment of childhood overweight and obesity with the purpose of informing future clinical practice guidelines within this field. The aim is to conduct this investigation in an optimal trial design with the lowest possible risk of bias.

Detailed description

Obesity is a chronic, progressive, and severe disease that compromises growth, development, and the general health and well-being of children, adolescents, and adults all around the globe. Current treatment within this field varies considerably, but the prevailing concept is that treatment should be lifelong with a focus on implementing and maintaining changes regarding diet, physical activity, sedentary behavior, sleep, etc. The Holbæk Obesity Treatment (HOT) is built on the understanding that obesity is a complex chronic disease regulated by a neuroendocrine system, where weight-reducing actions initiate counteractive mechanisms to defend fat mass. Conventional obesity treatment (COT) is based on a view that obesity results from energy imbalances and focuses on motivation, few changes at a time, and a narrative approach towards healthy energy intake and physical activity. These two approaches represent fundamentally different treatments of overweight and obesity.

Interventions

Type	Name	Description
BEHAVIORAL	Holbæk Obesity Treatment	Obesity is a chronic, progressive, severe, recidivistic, and complex disease, which mandates that children and adolescents with overweight or obesity have access to a professional medical healthcare service as other pediatric chronic diseases, implying a lifelong course of treatment. The HOT method is further based on the physiological insight into the endocrine regulation of fat mass; especially on how the body adapts when it is challenged by weight loss. These insights include an understanding where the body shifts into an energy-preserving mode when the individual is initiating weight-reducing actions, such as a reduced caloric intake or an increased level of physical activity, which has numerous impacts on communication and pedagogy. HOT is administered by healthcare nurses and dietitians at healthcare centers in Danish municipalities. Each treatment will be conducted as face-to-face sessions totalling a range of six to 12 hours for 12 months.
BEHAVIORAL	Conventional Obesity Treatment	Obesity is viewed as a chronic disease that is ultimately thought to result from an imbalance between energy intake and energy expenditure. However, multiple factors, both environmental and genetic, are thought to influence the disease as well. As obesity reflects energy imbalances, the treatment plan should be designed to induce a slightly negative energy balance by focusing on diet, physical activity, and inactivity through behavior change. Taking one step at a time, will in the end lead to the same energy balance result (i.e. weight loss) and will be more sustainable for the participant whose motivation is absolutely pivotal in this process. COT is administered by healthcare nurses and dietitians at healthcare centers in Danish municipalities. Each treatment will be conducted as face-to-face sessions totalling a range of six to 12 hours for 12 months.
