[Health Related Quality of Life, Self-Esteem and Health Behaviour on Average 6 Years after an Obesity Outpatient Lifestyle Program].

Background Multimodal programs focusing on weight reduction are recommended in guidelines for the treatment of obese children. However, studies investigating the effects of such programs over time are still missing; there is especially a lack of studies considering longer periods after treatment. In the present study, adolescents' bodyweight, health-related quality of life (HRQoL), self-esteem and health behavior were assessed before and directly after the treatment as well as 3 years after the treatment. Methods Between 2005 and 2009 84 children and adolescents took part in a 10-month, multimodal training programme. A number of 55 participants were assessed before (T0), after (T1) and at least 3 years after the beginning of the programme (T2). Based on height and weight the Body mass index standard deviation score (BMI-SDS) was calculated. Further, HRQoL, self-esteem, physical activity and eating behavior were measured by means of standardized questionnaires. Results On average 6 years after program beginning the BMI-SDS decreased by 0.4 compared to program beginning (p<0.01). The HRQoL total score increased from 70.1±12.1 at T0 to 76.2±12.8 at T2 (p<0.05). The self-esteem also increased from 54.0±23.4 (T0) to 65.0±21.5 (T2; p<0.05). In addition, in the long run the physical activity (p<0.05) and the interest in sports (p<0.001) increased. However, the eating behavior did not improve significantly. Conclusion In addition to weight and health behaviour improvements participating in a multimodal training program is associated with a clinical relevant increase of HRQoL and self-esteem. These improvements of protective factors can diminish the risk of discrimination and should be analysed in further controlled studies.
