%X objectives: to identify the way school material is carried and the weight of the material carried, and to compare these findings for 2nd, 5th and 9th graders. methods: this study evaluated 58 students from a randomly selected school in dois irm£¿os, a city in southern brazil, using anthropometric variables and a questionnaire to identify what schoolchildren used to carry school material and the way it was carried. school material was weighed over a five-day period. descriptive statistics was used to analyze the responses to the questionnaires. mean weight of the school material, normalized by body weight, was analyzed using one-way anova and the bonferroni post hoc test (¦Á=0.05). results: second, 5th and 9th graders carried their own material using a backpack with two straps (60.0%, 77.3%, and 85.5%, p<0.05) over their shoulders (60.0%, 77.3%, and 81.0%, p<0.05), and mean rate of schoolbag weight to body weight was 7.2%¡À2.3, 8.8%¡À3.0, and 5.9%¡À1.7. the only significant difference (p<0.05) was between 5th and 9th graders. conclusion: students in the 2nd, 5th and 9th grades prefer to carry their school material using a backpack with two straps symmetrically placed over the shoulders. regardless of school grade, the backpack weight was less than 10% of body weight, and 5th graders carried the heaviest relative loads.
