Non-communicable diseases in adulthood are reported to be strongly associated with adolescent obesity. The present study aimed to assess the effect of a comprehensive lifestyle modification intervention on the anthropometric indices, dietary intake, and physical activity of adolescent boys with overweight.
This pragmatic trial was conducted on 126 adolescent boys with overweight. A comprehensive school-based intervention was carried out at two levels for four months: at the school level based on the Ottawa Charter framework and at the personal level including individualized diet and physical activity.
The percentage of mean difference of BMI and BF loss in the intervention group were 1.20% (P < 0.05) and 6.41% (P < 0.01), respectively. The intervention group had a lower intake of calorie (2350 ± 861 vs. 2634 ± 917 kcal/d), carbohydrate (255.68 ± 41 vs. 286.97 + 47 g/d), and fat (112.67 ± 78 vs. 217.72 ± 86 g/d) after the intervention compared to the control group (All P < 0.05). The intervention resulted in a significant increase in physical activity parameters including distance (3501 ± 287 vs. 614 ± 56 m/d), duration (203 ± 35 vs. 72 ± 10 min/d), and calorie expenditure (359.24 ± 62.4 vs. 46.74 ± 7.5 kcal/d) in the intervention group compared to the control group (P < 0.01).
A comprehensive lifestyle modification intervention which covers both school and individual levels may positively influence BMI, body fat, calorie intake, and distance and duration of physical activity in adolescents. Thus, adopting multifaceted strategies using the Ottawa Charter framework may be considered as an effective approach to managing obesity in adolescents.
据报道，成年期的非传染性疾病与青少年肥胖密切相关。本研究旨在评估综合生活方式改变干预对超重青少年男孩人体测量指标、饮食摄入和身体活动的影响。
对126名超重青少年男孩进行了这项务实试验。基于渥太华宪章框架在学校层面以及包括个性化饮食和身体活动的个人层面开展了为期四个月的综合校本干预。
干预组BMI和体脂减少的平均差异百分比分别为1.20%（P<0.05）和6.41%（P<0.01）。与对照组相比，干预组干预后热量摄入量（2350±861 vs. 2634±917千卡/天）、碳水化合物摄入量（255.68±41 vs. 286.97 + 47克/天）和脂肪摄入量（112.67±78 vs. 217.72±86克/天）均较低（所有P<0.05）。与对照组相比，干预使干预组的身体活动参数显著增加，包括距离（3501±287 vs. 614±56米/天）、持续时间（203±35 vs. 72±10分钟/天）和热量消耗（359.24±62.4 vs. 46.74±7.5千卡/天）（P<0.01）。
涵盖学校和个人层面的综合生活方式改变干预可能对青少年的BMI、体脂、热量摄入以及身体活动的距离和持续时间产生积极影响。因此，采用基于渥太华宪章框架的多方面策略可被视为管理青少年肥胖的有效方法。
