Mobile Health Intervention to Identify Early Responders to Treatment in Adolescent Obesity

Adolescent Obesity Clinical Trial

Official title: Pilot Evaluation of a Mobile Health Intervention to Identify Early Responders to Treatment in Adolescent Obesity as a Triage Approach

Status Completed

Clinical Trial Summary

Background: The Expert Committee on the Assessment, Prevention and Treatment of Child and Adolescent Overweight and Obesity recommends a staged based approach to the management of adolescents with overweight and obesity from Stage 1-4 with increasing intensity of management in higher stages. Mobile health application is an attractive community based treatment for adolescent obesity due to its wide penetration and convenience. Early weight loss has been found to be the strongest predictor of good long term outcome in obesity. However there is currently no known study that use early weight loss as a predictor factor for a stepped up approach using a mobile health application.

Clinical significance: The current study use a mobile health intervention to identify participants with early weight loss in a stepped up approach.

Primary objective will be to examine the proportion of patients triaged to the low risk Weight Management Clinics (WMC) after brief intervention by a nurse coordination and completion of 4 sessions of Kurbo Program over a 12 month recruitment period.

Secondary objectives will be to examine changes in BMI z-score, metabolic profile, examine program feasibility and fidelity and explore other predictors of poor response to program.

Methodology:

Children aged 13-17 years old with BMI percentile of above 90th percentile, who are referred to the WMC, will receive a brief intervention by the WMC nurse coordinator followed by introduction to Kurbo program, a multifunctional mobile application, for more detailed dietary and physical activity recommendations and implementation of behavioural changes. Patients that are able to engage with Kurbo intervention and showed a decrease in BMI percentile over 4 sessions of Kurbo will be offered the low risk weight management clinic.

At baseline, month 3 and month 6, the patient's weight and height, body fat composition, waist circumference and blood pressure will be measured as per usual standard protocol. Questionnaires to assess eating, quality of life and dietary recall will be administered as part of the research. Accelerometers will also be fitted to assess physical activity.

At baseline and month 6, metabolic blood tests (HbA1C, fasting lipid panel, oral glucose tolerance test, fasting insulin level and liver function test) were collected after a minimum 8 hour fasting period together with bloods for aromatic amino acid, branch chain amino acid and long chain acylcarnitines .

Current low risk WMC patients will be offered 2 monthly follow up with optional dietician and exercise physiologists counselling and exercise sessions. The high risk WMC patients will be routinely offered the standard high risk follow up protocol consisting of weekly follow up with the multidisciplinary team for 4 weeks followed by 2 weekly appointments for 2 months and monthly appointment thereafter based on clinical response.
