Lifestyle modifications in an adolescent dormitory: a clinical trial

다국어 초록 (Multilingual Abstract)

Purpose: Childhood obesity is an increasing public health issue worldwide. We examined dietarypatterns among adolescents in a dormitory school, identified obese adolescents and tried to interveneto improve food habits and physical activity.
Methods: We conducted an experimental prospective longitudinal study based on 36 obese (bodymass index [BMI]≥95th percentile) adolescents (aged 12–18 years) compared with controls (healthychildren: normal age-appropriate BMI (BMI≤85th percentile). Six months’ intervention includedlifestyle-modification counseling (once a week by a clinical dietician), and an exercise regimen twicea week, 60 minutes each time, instructed by a professional pediatric trainer). Both groups underwentbaseline measurements at the beginning of the study and 6 months later (arterial stiffness, bloodpressure, pulse, weight and height, hemoglobin, creatinine, liver enzymes, highly sensitive C-reactiveprotein and complete lipid profile).
Results: Twenty-one participants completed the study. Low compliance from participants, schoolstaff and parents was observed (participation in planned meetings; 71%–83%). BMI significantlydecreased from 32.46±3.93 kg/m2 to 30.32±3.4 kg/m2 (P=0.002) in the study group. Arterialstiffness was not significantly different between the 2 groups and did not change significantly after 6months’ intervention (P=0.494). No significant changes in CRP and lipid profile were observed afterthe intervention.
Conclusion: Making lifestyle modifications among adolescents in a dormitory school is a complex task.
Active intervention indeed ameliorates BMI parameters. However, in order to maximize the beneficialeffects, a multidisciplinary well-trained team is needed, with emphasis on integrating parents and theschool environment.
