There are few practical, scalable, community-based solutions that provide ongoing support to combat the recent rapid rise in obesity in young people. A commercial weight management organisation (CWMO) has developed a tailored version of its programme for young people. The present study assessed the programme's impact on self-reported body weight, body mass index (BMI; kg m(-2) ) and health-related behaviour changes in participating young people.
Seventy-nine current young members completed a web-based questionnaire on age, height, weight and self-reported eating and activity behaviours for when they joined the programme and at the time of survey. Inclusion criteria were age 11-15 years old and membership for at least 1 month. Subjects completed the questionnaire online via the CWMO website. This was a retrospective observational study without a control group. All data were self-reported.
Mean (SD) age was 13.4 (1.4) years and start weight was 78.5 (16.7) kg; 67% were >99th centile for BMI. Mean (SD) attendance was 23 (19) weeks; weight change was -5.0 (4.5) kg; BMI change was -2.5 (2.0) kg m(-2) ; and BMI Z-score change was -0.5 (0.4) (all P < 0.001). Height increased by 0.01 (0.03) m (P < 0.01); however, height Z-score remained unchanged. Regression analysis showed that BMI Z-score change was related to increased fruit and vegetable intake (P = 0.012), as well as a decrease in avoidance of moderate and intense activity (both P < 0.003).
This programme for overweight and obese young people helped implement behaviour and lifestyle changes that were associated with significant reductions in self-reported weight and BMI Z-score, without compromising growth in height.
目前几乎没有实用、可扩展的社区解决方案，可以为对抗年轻人肥胖率的快速上升提供持续支持。一家商业体重管理机构 (CWMO) 已为年轻人量身定制了其项目版本。本研究评估了该计划对参与年轻人自我报告的体重、体重指数 (BMI; kg·m(-2) ) 和与健康相关的行为变化的影响。
79 名当前年轻成员通过 CWMO 网站在线填写了一份关于年龄、身高、体重以及加入计划时和调查时自我报告的饮食和活动行为的网络问卷。纳入标准为年龄 11-15 岁且会员资格至少 1 个月。参与者通过 CWMO 网站在线完成问卷。这是一项没有对照组的回顾性观察研究。所有数据均为自我报告。
平均（SD）年龄为 13.4（1.4）岁，起始体重为 78.5（16.7）kg；67%的人 BMI 超过第 99 百分位数。平均（SD）出席率为 23（19）周；体重变化为-5.0（4.5）kg；BMI 变化为-2.5（2.0）kg·m(-2) )；BMI Z 评分变化为-0.5（0.4）（均 P < 0.001）。身高增加了 0.01（0.03）m（P < 0.01）；然而，身高 Z 评分保持不变。回归分析表明，BMI Z 评分的变化与增加水果和蔬菜的摄入量有关（P = 0.012），以及减少对中等强度和高强度活动的回避（均 P < 0.003）。
该计划为超重和肥胖的年轻人提供了帮助，实施了行为和生活方式的改变，这些改变与自我报告的体重和 BMI Z 评分的显著降低相关，而不会影响身高的增长。
