Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Investigators Outcome Assessors
Due to the nature of the interventions, it will not be possible to blind the healthcare providers administering the interventions. We will attempt to blind the participants by not informing them about which intervention group we consider experimental and which group we consider control. However, the participants included in HOT will be governed by a digital solution where Dr. Holm will be identifiable and thus revealing the HOT. In all other aspects of the trial, we will employ blinding, incl. outcome assessment. Statisticians, and investigators drawing conclusions will be fully blinded. We will conduct the statistical analyses with the intervention groups coded as eg. 'A' and 'B'. The steering committee will write two abstracts while the blinding is intact; one assuming the experimental intervention group is 'A' and the control intervention group is 'B', and one assuming the opposite. After these two abstracts have both obtained consensus, the code will be broken.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

HOT

Holbæk Obesity Treatment

Group Type EXPERIMENTAL

Holbæk Obesity Treatment

Intervention Type BEHAVIORAL

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.

COT

Conventional Obesity Treatment

Group Type ACTIVE_COMPARATOR

Conventional Obesity Treatment

Intervention Type BEHAVIORAL

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.
