Abstract:
Objective To observe the effects of different interventions on the body mass index (BMI) and body fat content in overweight and obese adolescents, with an attempt to design reasonable weight relief program.Methods Totally 67 overweight or obese adolescents from a middle school of Beijing were randomly divided into three groups: control group ( n = 16 ), diet intervention group ( n= 22), and combined interventions group ( n =29). The changes of BMI and body fat rate (BFR) were observed. Results BMI significantly decreased after interventions ( diet intervention group: P = 0. 000; combined interventions group: P = 0. 018 ); the change of BMI in diet intervention group was significantly larger than that in control group ( P = 0. 035 ). The trunk and body BFRs also significantly decreased after interventions (diet intervention group: P=0. 000, P = 0. 013; combined interventions group: P = 0. 000, P = 0. 000 ); the changes of trunk and body BFRs were significantly larger in combined interventions group than those in control group ( P = 0.005, P = 0. 003 ). Conclusion Diet intervention and combined interventions are both effective in achieving weight loss in adolescents, and combined interventions have superior effectiveness.
