Exploring a Natural Solution for Childhood Obesity

This study aims to assess the safety tolerability, adherence and effectiveness of genistein as an anti-obesity treatment for children and adolescents. The primary goal is determining how well genistein is tolerated and adhered to by pediatric patients with obesity. Secondary goals include evaluating its impact on body mass index z-scores and cardiometabolic risk factors, such as inflammation. Participants aged 4-18 will be recruited from the Paediatric HEAL (Healthy Eating, Activity \& Lifestyle) Program at the Children's Hospital - London Health Science Center in London, Ontario. They will receive genistein treatment over 6 months, with interim assessments at 3 and 6 months to monitor efficacy, safetytolerability, and adherence, and efficacy, and potentially increase the dose at the 3-month visit. A final assessment will occur after a 3-month washout to observe any lasting effects. Blood and urine samples will be collected to analyze various adherence and health markers, including inflammatory and cardiometabolic factors. For participants who are of childbearing potential and have had their first menses, the blood analysis will also include pregnancy testing. Laboratory testing will be performed at baseline, at three and six months while taking genistein and three months after the washout period. Urine samples will also confirm that genistein has been taken appropriately throughout the study. The study expects that genistein will be well-tolerated by children, reduce BMI z-scores by 0.2 (0.5), and improve cardiometabolic risk factors such as blood pressure, lipid profiles, and inflammation. A sample size of 60 participants has been calculated to achieve statistically significant results, which will inform more extensive studies on genistein's potential for managing pediatric obesity.
