About this study
Official title: Long-term Results of an Interactive Mobile Health Support System and Daily Home-weighing as an add-on to Pediatric Obesity Lifestyle Treatment: A 3-year Pragmatic Clinical Trial
This study aims to evaluate if a web-based digital support system aiming to replacing or complement standardized pediatric behavioural obesity treatment. The hypothesis is that a digital system of communication between the family and the clinic can generate improved treatment results (change in BMI SDS) and reduce the number of missed visits.
Read the detailed description
Childhood obesity treatment is time consuming for both the health care system, and for the involved families. There is an association between the intensity and the outcome of treatment.
In this study all children who start treatment for childhood obesity will use a digital support system as a complement to behavioral treatment. The digital support system includes daily weighing on scales that do not show any digits, linked to a mobile app where weight development is shown as a moving average in the form of BMI standard deviation score (SDS). The app also provides an individual target curve visualizing the expected weight journey. Weight in growing children is complex to interpret why BMI SDS is used. Objective data from scale are automatically transferred to the database and the clinic and the family have direct contact with the clinic via the app.
The present study is a continuation of the investigators previous one-year study, Clinicaltrials.gov ID: NCT04323215. In this follow-up study, the investigators aim to assess the treatment outcomes over a three-year period.
The evaluation will be carried out on 107 children who underwent digi-physical treatment for three years. The results will be compared with a matched control group (n=321) from the Swedish childhood obesity treatment register, BORIS.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in degree of obesity (time frame: From start of treatment to three years follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06434259, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 May 2024.
