To examine age and gender differences in schoolbag use and to compare findings in Greece with those of other countries.
Schoolbag weight and carrying characteristics were assessed in 703 boys and girls aged 6 to 14 years.
Multinomial logistic regression models showed that younger students (6-8 years) were almost 5 more times more likely to carry heavier schoolbags than older students (p < 0.05). Similarly, more girls than boys carried heavier bags, and girls were twice more likely to experience fatigue symptoms when carrying schoolbags compared with boys (p < 0.05). The mean schoolbag weight was 12.4% of the student's body weight and moderately heavier than that reported for other countries.
Younger children are in greater need for education about schoolbag weight compared with older ones. There is also evidence that girls might experience more problems when carrying their schoolbag compared with boys.
研究书包使用方面的年龄和性别差异,并将希腊的研究结果与其他国家进行比较。
对703名6至14岁的男孩和女孩的书包重量及携带特征进行了评估。
多项逻辑回归模型显示,年龄较小的学生(6至8岁)携带较重书包的可能性几乎是年龄较大学生的5倍多(p < 0.05)。同样,携带较重书包的女孩比男孩更多,并且与男孩相比,女孩在携带书包时出现疲劳症状的可能性是男孩的两倍(p < 0.05)。书包的平均重量为学生体重的12.4%,略高于其他国家报告的重量。
与年龄较大的孩子相比,年龄较小的孩子更需要接受有关书包重量的教育。也有证据表明,与男孩相比,女孩在携带书包时可能会遇到更多问题。
