摘要


目的:结合身体成分测定、静息能量消耗和代谢因素分析,探讨肥胖儿童青少年进行饮食和运动的综合干预效果。方法:20名7-17岁的肥胖儿童青少年参与并完成了为时四周的夏令营项目。该项目重点关注个体行为,包括饮食限制和运动训练。在项目开始前和结束后分别进行人体学测量、生物电阻抗、腹部超声和核磁共振测定(评估腹部皮下和肝内脂肪),以及血压测定。结果:1.总体重平均减轻7.2±2.2 kg,脂肪质量减少5.5±2.2 kg,去脂体质量减少1.7±1.2 kg,并分别与腹部和臀部脂肪、腰臀比、血压的减少相关联。2.静息能量代谢测定值与体重矫正后的静息能量代谢值的变化无统计学意义。3.尿酸、总胆固醇、甘油三酯、低密度脂蛋白、糖化血红蛋白、胰岛素、C肽及胰岛素抵抗指标(HOMA-IR)明显降低,脂肪肝的发生率也明显减少,但hsCRP无显著差异。结论:通过四周的减肥夏令营的行为干预,能有效改善体脂肪含量及其分布,也会损失一定量的去脂组织,但静息能量代谢无减少。提示如能延长这种体重管理项目的干预期限,可有效地维持基础能量消耗,使减脂效果更好。

Objective: To investigate the effects of a combined intervention of diet and physical activity on body composition, resting energy expenditure (REE) and metabolic factors in obese children and adolescents. Methods: Twenty obese children and adolescents aged 7 to 17 years completed a 4-week summer camp program which focussed on personal behaviour, including energy-restricted diets and supervised physical activity. Anthropometry, bioelectrical impedance, ultrasonography (US) for subcutaneous and hepatic fat, and abdominal Magnetic Resonance Imaging assessments were made and blood pressure (BP) recorded before and after the 4-week intervention. Results: 1) Weight loss was 7.2±2.2 kg, with losses of 5.5±2.2 kg and 1.7±1.2 kg in fat mass (FM) and fat free mass (FFM), respectively, with associated reductions in abdominal and hip fat and in the waist/hip circumference ratio and in BP. 2) There were no significant changes in REE or in its ratio with weight. 3) Reductions in uric acid, total cholesterol, triglycerides, LDL cholesterol, HbA1C, insulin, C-Peptide and insulin resistance (HOMA-IR) and the ratio of fatty liver were observed, but not in the inflammatory marker hsCRP. Conclusions: With behavioural intervention during a summer camp, body fat and its distribution were favourably changed, but with some loss of lean mass. However, there were no detectable reductions in REE. Weight management programs which achieve fat loss with maintenance of REE ought to be more sustainable.
