52 Does Multidisciplinary Group Therapy Improve Outcome in Overweight/Obese Children and Adolescents?

Abstract

Objectives: Evaluate the impact of ambulatory group therapy (GT) versus individual therapy (IT) on a large group of overweight/obese children and adolescents.Methodology: Self-referred overweight and obese children/adolescents, were invited to participate and randomised to GT or IT for 4 months. GT included physical activity, dietary education and psychological sessions (2×3 hrs/week including 3hrs/ 2 weeks with parents). IT was made to measure and consisted of counselling of the child and its family on healthy lifestyle. Dietary advice and psychological support were available, when deemed necessary. Changes in BMI Z-score, WC-Z-score, glucose and fat metabolism, eating habits, lifestyle, wellbeing and self esteem were investigated. The study was approved by the National Medical Ethical Committee (CNER).Results: 192 children and adolescents participated with informed consent (age range 7-17 years; F: 53.6%). After 4 months, a BMI Z-score reduction was observed with a significantly better outcome in the GT. Positive changes in weight status were observed in 19% of children in the GT compared to 5.9 % of those following IT. Biological parameters show a small change over time but not significantly different between the two groups. Positive changes in eating habits as well as lifestyle were observed more frequently in the GT children, although not all reached statistical significance. Self perceived wellbeing as well as happiness with themselves improved after the GT.Discussion: Overall, GT resulted in slightly better results in almost all domains, however without reaching statistical significance. Sustainability in time and cost/benefit need further follow up.
