School-based interventions have reported effectiveness on back health; however, there are no specific guidelines for teaching body mechanics and posture in primary and secondary schools. To identify, describe, and analyze the educative features of randomized controlled trials (RCTs) on back health developed to date in the school setting, a systematic review was performed following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) recommendations. RCTs exclusively focused on educational setting electronic databases included PubMed, EMBASE, PEDro, Web of Science, SPORTDiscus, ERIC, and MEDLINE on the Ovid platform. Databases were searched for potentially eligible studies from the earliest date up to 18th March 2020. A total of 584 records were obtained from the database searches. A total of six articles that applied inclusion criteria were assessed for eligibility. All of these studies found improvements in postural habits and the level of knowledge with regard to back health, as well as a reduction in the prevalence of back pain. None of the studies used the student-centered method, and three studies used evaluation instruments with a pilot validation. Research on RCT interventions concerning back health in the school setting is scarce. None of the interventions applied a constructivist or student-centered method. The use of validated and standardized assessment instruments is required.

在学校环境中教授健康：随机对照试验的系统回顾


据报道，以学校为基础的干预措施对背部健康有效；然而，中小学的身体力学和姿势教学并没有具体的指导方针。为了识别、描述和分析迄今为止在学校环境中开发的背部健康随机对照试验 (RCT) 的教育特征，按照系统评价和荟萃分析 (PRISMA) 建议的首选报告项目进行了系统评价。专门针对教育环境的随机对照试验电子数据库包括 Ovid 平台上的 PubMed、EMBASE、PEDro、Web of Science、SPORTDiscus、ERIC 和 MEDLINE。从最早的日期到 2020 年 3 月 18 日，我们在数据库中搜索了可能符合条件的研究。从数据库搜索中总共获得了 584 条记录。总共对六篇应用纳入标准的文章进行了资格评估。所有这些研究都发现姿势习惯和背部健康知识水平的改善，以及背痛患病率的降低。没有一项研究使用以学生为中心的方法，三项研究使用了经过试点验证的评估工具。关于学校环境中背部健康的随机对照试验干预措施的研究很少。所有干预措施都没有采用建构主义或以学生为中心的方法。需要使用经过验证和标准化的评估工具。
