Brief Summary

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

The main purpose of the present study is to perform a 10 weeks dietary intervention study with a follow-up for 52 weeks in children from 7-14 years of age with overweight or obesity. In a caloric restricted and increased physical activity setting the control group will consume a low-moderate protein (15E%/day) diet whereas the intervention group will consume a higher protein (25E%/day) diet. Secondary, the investigators want to investigate the effect of frequent follow-up after the intervention, and the overall effect of the lifestyle camp.

Compared to the low-moderate protein diet, the investigators hypothesis that a diet with higher consumption of protein-containing foods will more effectively induce weight loss (a reduction in BMI-SDS) or weight maintenance in children with overweight or obesity, and improve quality of life, and risk factors for type 2 diabetes.

Detailed Description

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

The study will be performed in collaboration with the staff of the well-established multi-component-overnight camps (Julemærkehjem) in Denmark. The multi-component-overnight camps are intensive weight loss camps to which Danish schoolchildren, from 7-14 years of age, are referred to for 10-weeks intervention focusing on healthy lifestyle, healthy eating, new habits and increased physical activity.

The primary outcome is anthropometry (BMI-SDS, fat mass, fat-free mass). Secondary outcomes are metabolic health and questionnaires investigating quality of life, eating behavior traits, eating habits and eating-related problems i.e., overeating and loss of control eating.

The children will be measured at baseline, 10-weeks and at a 52-weeks follow-up visit.

Furthermore, participants will be invited to follow-up visits 3 years, 5 years, 7 years and 10 years, respectively.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

FACTORIAL

1. SARS CoV group (former control group): Current weight-loss diet (15E%/day protein) for the 10 weeks they attend the camp, however, due to a COVID19 lockdown of the camps, these children were sent home for five weeks, and therefore excluded from longitudinal comparison between the groups.
2. Control group (CG): Current weight-loss diet (15E%/day protein) for the 10 weeks they attend the camp.

2\) Intervention group (IG): A higher protein diet (25E%/day) for the 10 weeks they attend the camp.

Participants Investigators
At enrollment the participants have no knowledge of which group they are assigned.

The investigator has no knowledge of or influence on how participants are divided into different groups. Participants are assigned groups by the camp staff.

Study Groups

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

SARS CoV-group

This group should have been the control group. However, due to the COVID19 lockdown of the camps for 5 five weeks, with no control of diet and physical activity, this group could not act as control group. Therefore, this group has been excluded from longitudinal analyses.

Group Type OTHER

Diet with a lower amount of protein (15E% per day)

Intervention Type DIETARY_SUPPLEMENT

In a caloric restricted and increased physical activity setting, the participants will be served a low-moderate protein (15E%/day) diet.

Control Group (CG)

Current weight-loss diet (15E%/day protein) for the 10 weeks they attend the camp. Increased follow-up contact after camp.

Group Type ACTIVE_COMPARATOR

Increased follow-up contact after the 10-week intervention

Intervention Type BEHAVIORAL

Both the control-group and the intervention-group were offered an increased follow-up contact after camp.

Diet with a lower amount of protein (15E% per day)

Intervention Type DIETARY_SUPPLEMENT

Intervention group (IG)

A higher protein diet (25E%/day) for the 10 weeks they attend the camp. Increased follow-up contact after camp.

Group Type EXPERIMENTAL

Diet with a higher amount of protein (25E% per day)

Intervention Type DIETARY_SUPPLEMENT

In a caloric restricted and increased physical activity setting, the participants will be served a higher protein (25E%/day) diet.

Increased follow-up contact after the 10-week intervention
