Effekte einer Lebensstilintervention auf den BMI-SDS und die Lebensqualität im Follow-up über 12 Monate bei übergewichtigen und adipösen Kindern

Background: Childhood overweight and obesity are associated with impaired quality of life (QoL). The aim of this study was to evaluate the effects of a specific weight-loss therapy on QoL and body mass index (BMI-SDS) in overweight and obese children one year after beginning the therapy program. Participants and methods: Overweight and obese children undergoing a 4-6 week inpatient lifestyle-change therapy program were examined within a prospective study (LOGIC-Trial). At both baseline and completion of the therapy program, data on body height and weight were collected and QoL was assessed by questionnaires (KINDL®). One year after the start of the therapy the children visited their general practitioner for a follow-up examination of body height and weight (n=240) and completed the KINDL®-questionnaire (n=187). Results: Over the course of the therapy, BMI-SDS declined by 0.4±0.1 (p<0.001). Although BMI-SDS increased during followup (p<0.05), values at 12 months were significantly lower than those measured at baseline (2.7±0.5 vs. 2.3±0.7; p<0.001). QoL increased by eight percent during the therapy (65.7±12.5 vs. 71.4±11.0 points; p<0.05), and QoL remained increased after 12 months in females (66.6±14.4 points, p<0.05). In males QoL returned to baseline levels after 12 months (p<0.05). Conclusion: This inpatient lifestyle-change therapy is effective in significantly reducing BMI-SDS after 12 months. QoL was improved over the course of the therapy, and sustained effects after one year were observed in females.
