This paper describes the rationale, design, and methods of a two-year randomized controlled trial conducted to evaluate the effectiveness of an environmental intervention in 27 elementary schools in Mexico City.
There were two units of analysis, school level addressing changes in elementary public part-time schools, and individual-level addressing behavioral changes in students 9 to 11 years of age. Two intensities of an intervention program were implemented (basic and plus), each containing two intervention components: physical activity and nutrition, supported by a communication/education component. Evaluation of the intervention was carried out during the school cycles 2006-2007 and 2007-2008.
Primary outcomes were overweight and obesity prevalence and fitness; environmental and behavioural measures were also examined.
This is the first institutional multilevel, multifactorial project, consistent with the best practices available in current literature, carried out in Mexico to prevent childhood obesity in schools.
本文描述了一项为期两年的随机对照试验的基本原理、设计和方法，该试验旨在评估在墨西哥城27所小学开展的一项环境干预措施的有效性。
有两个分析单位，学校层面针对小学公立非全日制学校的变化，个体层面针对9至11岁学生的行为变化。实施了两种强度的干预计划（基础版和加强版），每个计划包含两个干预组成部分：体育活动和营养，并辅以一个沟通/教育组成部分。在2006 - 2007学年和2007 - 2008学年对干预措施进行评估。
主要结果是超重和肥胖患病率以及健康状况；还对环境和行为指标进行了检查。
这是墨西哥开展的首个符合当前文献中最佳实践的机构性多层次、多因素项目，旨在预防学校中的儿童肥胖。
