The EdAL (Educació en Alimentació) study is a long-term, nutrition educational, primary-school-based program designed to prevent obesity by promoting a healthy lifestyle that includes dietary recommendations and physical activity.The aims are: 1) to evaluate the effects of a 3-year school-based life-style improvement program on the prevalence of obesity in an area of north-west Mediterranean 2) To design a health-promotion program to be implemented by health-promoter agents (university students) in primary schools.
METHODS/DESIGN: 1) The intervention study is a randomised, controlled, school-based program performed by university-student health-promoter agents. Initial pupil enrolment was in 2006 and continued for 3 years. We considered two clusters (designated as cluster A and cluster B) as the units for randomisation. The first cluster involved 24 schools from Reus and the second involved 14 schools from surrounding towns Cambrils, Salou and Vilaseca combined in order to obtain comparable groups. There are very good communications between schools in each town, and to avoid cross influence of the programs resulting from inter-school dialogue, the towns themselves were the unit for randomisation. Data collected included name, gender, date and place of birth at the start of the program and, subsequently, weight, height, body mass index (BMI) and waist circumference every year for 3 years. Questionnaires on eating and physical activity habits are filled-in by the parents at the start and end of the study and, providing that informed consent is given, the data are analysed on the intention-to-treat basis.The interventions are based on 8 nutritional and physical activity objectives. They are implemented by university students as part of the university curriculum in training health-promoter agents. These 8 objectives are developed in 4 educational activities/year for 3 years (a total of 12 activities; 1 h/activity) performed by the health-promoter agents in primary schools. Control pupils follow their usual activities.2) Courses on education and promotion of health, within in the curriculum of medicine and health sciences for university students, are designed to train health-promoter agents to administer these activities in primary schools.
This controlled school-based intervention will test the possibility of preventing childhood obesity.

EdAL（饮食教育）研究是一个长期的、以营养教育为基础的小学项目，旨在通过促进健康的生活方式来预防肥胖，其中包括饮食建议和体育活动。目的是：1）评估为期 3 年的基于学校的生活方式改善计划对西北地中海地区肥胖患病率的影响；2）设计一个由健康促进人员（大学生）在小学实施的健康促进计划。
方法/设计：1）干预研究是一项由大学生健康促进人员实施的随机对照学校为基础的方案。初始入学时间为 2006 年，并持续了 3 年。我们将两个集群（指定为集群 A 和集群 B）视为随机分组的单位。第一个集群包括来自雷乌斯的 24 所学校，第二个集群包括来自周边城镇卡姆布里尔斯、萨洛和比利亚塞卡的 14 所学校，以便获得可比的群组。每个城镇的学校之间都有很好的交流，为了避免由于校际对话而导致项目之间的交叉影响，将城镇本身作为随机分组的单位。收集的数据包括计划开始时的姓名、性别、出生日期和地点，随后每年记录 3 年的体重、身高、体重指数（BMI）和腰围。饮食和体育活动习惯的问卷由家长在研究开始和结束时填写，如果获得了知情同意，将基于意向治疗原则分析数据。干预措施基于 8 个营养和体育活动目标。这些干预措施是由大学生作为大学课程的一部分，以培训健康促进人员来实施的。这 8 个目标是在 3 年内每年进行 4 次教育和体育活动（共 12 次活动；每次活动 1 小时），由健康促进人员在小学实施。对照组学生遵循他们的常规活动。2）在医学生和健康科学学生的课程中设计了关于健康教育和促进的课程，旨在培训健康促进人员在小学实施这些活动。
这项基于学校的对照干预将检验预防儿童肥胖的可能性。
