Heavy schoolbags are reported worldwide including India. The prescribed safe upper limit was 10% of student bodyweight.
This intervention study explored (a) impact of awareness measures among stakeholders and (b) any systemic constraints for reducing bag loads.
This is a two-stage intervention study following a 2016-2017 baseline study of schoolbag weights in two rural schools.
The study involved 175 students (male: 79 and female: 96) from 8 to 9 standards. The intervention consisted of sharing the baseline findings of schoolbag weight, guidelines, and necessary measures for the same. Thefirst intervention involved creating awareness among teachers regarding the harmful effects and the second intervention involved students. Bag weights were recorded on digital luggage scale in prelunch sessions in the following weeks after the intervention.
The impact of interventions was tested with (a) Paired -test for mean bag weights and (b) Chi-square test for the proportion of heavy schoolbags.
The mean baseline bag weight of 3.77 kg declined statistically significantly after successive interventions to 3.4 and 3.2 kg. The baseline proportion of 51% of heavy bags (>10% of body weight) declined to 38% and 29%. Despite interventions, 19% students in 8 carried heavier bags than the 3.4 kg cap set by Government guidelines. Subjects taught in 8 standard were above 6/day.
Awareness programs for stakeholders only partially succeeded in reducing bag weights. Hence, reducing the daily subject load is necessary.
包括印度在内,全球都有关于学生书包过重的报道。规定的安全上限是学生体重的10%。
本干预研究探讨了(a)利益相关者之间提高认识措施的影响,以及(b)减轻书包重量的任何系统性限制。
这是一项两阶段干预研究,之前在2016 - 2017年对两所农村学校的书包重量进行了基线研究。
该研究涉及175名8至9年级的学生(男生79名,女生96名)。干预措施包括分享书包重量的基线研究结果、指导方针以及相关必要措施。第一次干预是让教师了解其有害影响,第二次干预针对学生。在干预后的接下来几周,于午餐前时段用数字行李秤记录书包重量。
通过(a)书包平均重量的配对t检验和(b)超重书包比例的卡方检验来测试干预措施的效果。
经过连续干预后,书包平均基线重量从3.77千克显著下降至3.4千克和3.2千克。超重书包(>体重的10%)的基线比例从51%降至38%和29%。尽管采取了干预措施,但8年级仍有19%的学生背着比政府指导方针规定的3.4千克上限更重的书包。8年级每天的课程科目超过6门。
针对利益相关者的提高认识计划在减轻书包重量方面仅取得部分成功。因此,减少每日课程科目负担是必要的。
