背景/目的：全球越来越认识到需要有效的战略来预防和控制儿童肥胖。在这项研究中，我们的目的是确定一个肥胖预防计划的有效性，重点是在学校激励环境。对象/方法：在这项以学校为基础的前瞻性准实验研究中，我们招募了韩国忠州的三所小学（四年级）和两所中学（七年级）。我们将其中三所学校分配给干预组，两所学校分配给对照组。干预组接受1年的环境干预。在休息时间，通过互联网协议电视服务提供与饮食和运动相关的教育视频内容，并在学校楼梯和走廊上绘制各种设计材料，以鼓励体育活动。超重和肥胖的学生被建议参加暑假肥胖护理计划。结果：最终受试者总数为768人（对照组350人，干预组418人）。随访1年后，两组超重/肥胖发生率和缓解率无显著差异。然而，与对照组相比，干预组在体重指数（BMI） z分数(- 0.11(95%可信区间(CI) - 0.16至- 0.06)，身高（1.1 cm (95% CI 0.8至1.4)，P<0.001），体脂减少和肌肉质量增加方面表现出更大的下降。此外，血压（BP）显著降低，体质也有显著改善。在亚组分析中，体重正常的学生、男孩和年龄较小的参与者在体重相关的结果中表现出最有益的结果。此外，血压降低在高BMI组、男孩和年龄较大的儿童中更为明显。结论：简单的环境干预可以有效地影响儿童。通过增加先前研究的策略，我们可以为儿童制定更有效的肥胖预防计划。
Background/Objectives:There has been an increasing global recognition of the need for effective strategies to prevent and control childhood obesity. In this study, we aimed to identify the effectiveness of an obesity prevention program focused on motivating environments in school.Subjects/Methods:In this school-based, prospective, quasi-experimental study, we enrolled three elementary (fourth graders) and two middle (seventh graders) schools located in Chungju, Korea. We assigned three of the schools to the intervention group and two schools to the control group. The intervention group received 1 year of environmental intervention. Diet- and exercise-related educational video content was provided by internet protocol television services during rest time, and various design materials were painted along the school staircase and hallway to encourage physical activities. Overweight and obese students were recommended to join the summer vacation obesity care program.Results:The final number of total participants was 768 (control 350 and intervention 418). After 1 year of follow-up, there was no significant difference in the overweight/obesity incidence rates and remission rates between the two groups. However, the intervention group showed a greater decrease in the body mass index (BMI) z-score (−0.11 (95% confidence interval (CI) −0.16 to −0.06), P<0.001), increase in height (1.1 cm (95% CI 0.8 to 1.4), P<0.001), reduction of body fat, and increase in muscle mass compared with the control group. In addition, blood pressure (BP) was significantly reduced, and significant improvement in physical fitness followed. In subgroup analysis, students of normal weight, boys and younger participants showed the most beneficial results in weight-related outcomes. In addition, the BP reduction was more pronounced in the higher BMI group, boys and older children.Conclusions:A simple environmental intervention could effectively influence children. By adding to previously studied strategies, we can develop a more effective obesity prevention program for children.
