When elementary students came to school, student weights, their backpack weights, backpack types, and back-pain were measured by trained research assistants. Student weights and their backpack weights were measured by weighing beams. Weight of students were used by the school-data. The other information got to interview to children. Data management and analysis were performed using SPSS 12.0 version software.
