NCT ID: NCT03561597 Recruiting - Adolescent Obesity Clinical Trials

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

Start date: April 10, 2018
Phase: N/A
Study type: Interventional

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.

Chronotropic Incompetence During Exercise in Obese Adolescents: Clinical Implications and Pathophysiology

Start date: November 1, 2016
Phase: N/A
Study type: Interventional

A reduction in peak heart rate (HR) and suppressed HR response during exercise is highly prevalent in obese populations. This phenomenon is also known as chronotropic incompetence (CI). In adult obese individuals, CI is independently related to elevated risk for major adverse cardiovascular events and premature death. Despite the established association between CI and prognosis in adult populations, the prognostic relevance of CI in adolescents with obesity has however deserved no attention, but is important. CI during exercise testing may indicate various, yet undetected anomalies, such as altered blood catecholamine and/or potassium concentrations during exercise, structural myocardial abnormalities or ventricular stiffness, impaired baroreflex sensitivity and cardiovascular autonomic dysfunction, atherosclerosis, or cardiac electrophysiological anomalies, which all have been detected in obese children and adolescents. However, whether CI during exercise testing may be a sensitive and specific indicator for these anomalies in obese adolescents has not been studied yet. In addition, the exact physiology behind obesity and development of heart disease remains to be studied in greater detail in obese adolescents. In this project, we examine the prevalence of CI (during maximal cardiopulmonary exercise testing, CPET) in 60 obese adolescents (aged 12-16 years) vs. 60 lean adolescents, and study the association between CI and changes in CPET parameters, lactate, catecholamine and potassium concentrations during CPET, biochemical variables, and cardiac electrophysiology (by ECG recording). In addition, the relation between CI and cardiac function (echocardiography) will be examined in a subgroup (29 lean and 29 obese) of these adolescents. In this regard, the diagnostic value of HR (responses) during maximal exercise testing will be clarified in obese adolescents, and the physiology behind the elevated risk for heart disease in obese adolescents can be explored.

NCT ID: NCT03458637 Completed - Adolescent Obesity Clinical Trials

Lifestyle Intervention of Obese Teenagers (LITE) Program

Start date: November 6, 2014
Phase: N/A
Study type: Interventional

Background: Family-based lifestyle intervention programmes have been known to reduce overweight and improve cardiovascular risk in adolescent obesity [1]. This study was designed to address the gap in service provision of a family based weight management program for overweight and obese adolescents. The LITE (Lifestyle Intervention for obese teenagers) group program is a 6-month, family-based behavioural lifestyle intervention, specifically designed to treat obesity in adolescents 10-16 years referred to the Weight Management Clinic. The main principles underpinning LITE program are that parents are identified as the agents of change responsible for implementing lifestyle change in the family . Methods: The study design is a two-arm randomized controlled trial that recruited 60 overweight and obese adolescents 10-16 year olds that attended Kandang Kerbau Women and Children's Hospital(KKH) weight management clinic. Adolescents with secondary cause for obesity are excluded. Participants are randomized to LITE program with usual care or usual care. Briefly, the LITE program involves four x 180 min weekly sessions, followed by three x 90 min monthly sessions, for adolescents and parents. The key aspects covered in the LITE program are in keeping with Health Promotion Board guidelines for the management of overweight and obesity and include healthy food choices and eating patterns, increasing physical activity and reducing sedentary behavior. The parenting aspects aim to support and increase parental capacity to implement and maintain the lifestyle changes. The program takes a solution focused approach with families identifying small changes that they would like to try each week instead of a child-centric approach. Outcome measurement are assessed at 3 and 6 months post baseline and include anthropometric measurements, physical activity, dietary intake, metabolic profile, improvement in positive parenting behaviour and measurement of family support. Primary outcome is change in body mass index (BMI) z-score at 6 months. Secondary aim is to evaluate the changes in waist-height ratio and fat percentage change and improvement in positive parenting behaviour.

NCT ID: NCT03364205 Completed - Obesity Clinical Trials

Solution Focused Approach in Adolescents (SFA)

Start date: September 2, 2013
Phase: N/A
Study type: Interventional

Aims-objectives: This study assessed the effect of the Solution Focused Approach (SFA) interview technique on overweight/obese adolescents' nutrition-exercise attitudes and behaviors. Background: Obesity is a serious health problem for all age groups, particularly adolescents; therefore, it is important for adolescents to develop healthy nutrition habits, acquire exercise behaviors. Unless healthy nutrition-exercise behaviors are acquired, obesity can develop in adolescence, continue in adulthood. Focusing on solutions can be effective for overweight/obese adolescents to develop healthy nutrition-exercise behaviors. Design: A pretest-posttest randomized-controlled trial design was used. Methods: The study included 32 overweight/obese adolescents (16 for intervention group, 16 for control group) aged12-13 years who attended a health center, met the inclusion criteria. The SFA interview technique was applied to the intervention group. Eight solution-focused interviews were conducted with each adolescent at two-week intervals (interview length 30 to 45minutes). For each group, anthropometric, metabolic measurement follow-ups were conducted in the first and sixth months. The data were evaluated using independent samples t-test, Mann-Whitney U, Wilcoxon test respectively for normally, non-normally distributed variables. The categorical variables were compared using chi-square test. The value p<0.05 was accepted to be statistically significant.

NCT ID: NCT03263351 Recruiting - Depression Clinical Trials

Depression & Insulin Sensitivity in Adolescents

Start date: October 1, 2017
Phase: N/A
Study type: Interventional

There has been a rise in type 2 diabetes (T2D) rates in adolescents, disproportionately in girls from disadvantaged racial/ethnic groups. This group of girls also is at heightened risk for depression, and depression and T2D are linked. Depressive symptoms are a risk factor for worsening of insulin sensitivity, one if the major precursors to T2D. In preliminary studies, the investigators found that a brief cognitive-behavioral therapy group decreased depressive symptoms and prevented worsening of insulin sensitivity in adolescent girls at-risk for T2D with moderate depressive symptoms. The aims of this study are: 1) to assess the efficacy of a cognitive-behavioral therapy depression group vs. a health education control group for improving insulin sensitivity and preserving insulin secretion in racially/ethnically diverse adolescent girls at-risk for T2D with moderate depressive symptoms over a 1-year follow-up; 2) to evaluate changes in eating, physical activity, and sleep as explanatory and 3) to test changes in cortisol factors as explanatory.

NCT ID: NCT03203161 Not yet recruiting - Morbid Obesity Clinical Trials

Registry on Obesity Surgery in Adolescents

Start date: September 2018
Phase: N/A
Study type: Observational

While bariatric surgery is established as a safe and effective alternative with well-defined risks for severely obese adults, little has been published on its use in children. There are many unresolved questions concerning the long-term metabolic and psychological consequences of bariatric surgery in adolescents, and the difference with the adult population. The appropriate timing for bariatric surgery in young people, and the predictors of success and safety still need to be determined. The aim of this long-term prospective study is therefore to establish the safety and efficacy profile of surgical procedures and to clarify whether reductions in morbidity and mortality outweigh the risks of serious surgical complications and lifelong nutritional deficiencies.
