研究目的：青少年时期是身体发育的重要时期，生活方式改变对肥胖控制的影响还没有得到定量评估。因此，我们调查的影响，报告的能量摄入量和身体活动的变化对人体测量和身体组成的青少年。MethodsParticipants是肥胖的青少年，年龄在11-18岁。根据2000年CDC生长图表，所有受试者的体重指数（BMI）均≥年龄和性别的第95百分位数。干预措施包括有监督的体力活动、结构化的营养教育和饮食调整以及6个月的行为支持。结果与基线相比，在6个月时观察到体重（− 1. 4 kg，p<0. 001）和BMI（− 0. 1 kg/m2，p<0. 001）显著降低。与2000年CDC生长图表上的预期生长轨迹相比，男孩的体重和BMI分别降低了3.6 kg和1.5 kg/m2，女孩分别降低了5.6 kg和1.9 kg/m2。年龄与体重（β= −1.48 kg，p< 0.01）和BMI（β= −0.32 kg/m2，p= 0.03）的变化呈负相关。能量摄入减少与体重减轻之间存在剂量反应关系。每天减少100千卡热量与体重减少0.30 kg、BMI减少0.09 kg/m2和BMIZ评分减少0.01显著相关（均P < 0.01）。体力活动没有显着相关的人体测量学或身体composition.ConclusionsReduction的能量摄入量的变化是一个显着的预测这些青少年的肥胖减少。青少年减肥计划的定量评估应该考虑自然生长和发育。
PurposeImpact of lifestyle modification on obesity control during adolescence, a period of significant physical growth and development, is less quantitatively evaluated. Therefore, we investigated the impact of changes in reported energy intake and physical activity on anthropometrics and body composition in adolescents.MethodsParticipants were obese adolescents aged 11–18 years. All of them have a body mass index (BMI) ≥ 95th percentile specific for age and gender according to the 2000 CDC Growth Charts. The intervention consists of supervised physical activity, structured nutrition education and dietary modification, and behavioral support in 6 months. Hundred and forty-five obese adolescents completed the study.ResultsCompared to baseline, significant reductions in body weight (−1.4 kg,p< 0.001) and BMI (−0.1 kg/m2,p< 0.001) were observed at 6 months. When compared to expected growth trajectories on the 2000 CDC Growth Charts, body weight and BMI were reduced by 3.6 kg and 1.5 kg/m2, respectively, in boys and 5.6 kg and 1.9 kg/m2in girls. Age was inversely associated with changes in weight (β= −1.48 kg,p< 0.01) and BMI (β= −0.32 kg/m2,p= 0.03). There was a dose–response relationship between reduction in energy intake and weight loss. A decrease of 100 kcal/day was significantly associated with reductions in body weight 0.30 kg, BMI 0.09 kg/m2, and BMIZscore 0.01 (allp< 0.01). Physical activity was not significantly associated with changes in anthropometrics or body composition.ConclusionsReduction in energy intake was a significant predictor of obesity reduction in these adolescents. A quantitative evaluation of adolescent weight loss programs should account for natural growth and development.
