About this study
The aim of the study is to examine the effects of pharmacological treatment for obesity on BMI trajectories and metabolic markers among patients in routine clinical care. A retrospective observational study. By collecting and analysing real-life data from the first children and adolescents in Sweden who have been offered pharmacological treatment for obesity, the results can contribute to a better understanding of how these treatments function in practice.

Aim
The aim of this sub-study is to evaluate the impact of liraglutide treatment on the trajectory of body mass index (BMI), including BMI according to International Obesity Task Force (IOTF) criteria and BMI standard deviation score (BMI SDS), as well as its effects on cardiovascular risk markers among children and adolescents treated with liraglutide in two Swedish regions. The study seeks to generate real-world evidence on the effectiveness of liraglutide in routine clinical practice.
Study Design
This is a retrospective, observational study based on medical records of children and adolescents who received multidisciplinary obesity care for at least one year and were treated with liraglutide during 2022-2023 at either the Pediatric Clinic in Region Halland or the Regional Childhood Obesity Center at Queen Silvia's Children's Hospital. The study is non-interventional and does not introduce any additional risks beyond standard clinical care. Participation was voluntary, with informed consent obtained from legal guardians and assent from children.
Participants
Eligible participants include children and adolescents who:
Were enrolled in multidisciplinary obesity care for at least one year
Received liraglutide treatment during 2022-2023 at one of the study sites
Were invited to participate either during clinical visits or via written invitation
Data on comorbidities, including neuropsychiatric diagnoses, were also collected to assess potential confounding factors.
Data Collection
Data were extracted retrospectively from medical records and include:
Demographics: sex, age
Anthropometrics: height, weight, BMI, BMI SDS, BMI according to IOTF criteria
Treatment details: titration period, maximum tolerated dose, and treatment outcomes at 3-6, 12, 18.
Metabolic parameters: blood pressure, lipid profile, fasting glucose, and HbA1c
Comorbidities: neuropsychiatric and other relevant diagnoses
All data were anonymized and handled in accordance with Swedish data protection regulations.
Statistical Analysis
Descriptive Statistics:
Continuous variables (e.g., age, BMI, metabolic parameters) will be summarized using mean ± standard deviation (SD) or median with interquartile range (IQR), as appropriate.
Categorical variables (e.g., sex, comorbidities) will be summarized using counts and percentages.
Treatment effects at 3-6, 12, 18, and 24 months will be evaluated using appropriate repeated measures models, accounting for potential confounders such as age, sex, baseline BMI, and comorbidities.
Handling of Missing Data:
Missing data will be assessed for patterns and mechanisms.
Multiple imputation or sensitivity analyses may be performed depending on the proportion and nature of missing values.
Statistical Collaboration:
All analyses will be conducted in collaboration with an experienced statistician.
The analysis plan and results will be reviewed and validated by both the statistician and study supervisors.
Ethical Considerations
Participation was voluntary and did not affect ongoing clinical care.
Informed consent was obtained from legal guardians, with assent from children.
Data were anonymized and managed according to Swedish data protection laws.
The study was retrospective and non-interventional; no specific approval from the Swedish Medical Products Agency was required.
All procedures adhere to the ethical principles of the Declaration of Helsinki.
Dissemination
Results will be disseminated through a peer-reviewed publication and scientific conference presentations. Sub-study III is expected to be finalized in 2026.

Where is the study taking place?
The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.
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 Body Mass Index Standard Deviation Score (BMI SDS) over time (time frame: The primary outcome, change in BMI SDS, will be evaluated at -12 months (pre-baseline), at baseline (0 months), and at +3-6, +12, and +18 months following treatment initiation.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 27 Feb 2026; AzTrials last refreshed its copy on 8 Nov 2026.
