The investigation pursues the objective of evaluating the disergonomic problems associated to the school furniture, to the dimensional characteristics of the classroom, and the weight of the school bag in relation to the anthropometric dimensions of the students in public and private schools. For this purpose, anthropometric measurements were taken to 413 children from three public schools and three private schools. Among the variables taken, we can find the following ones: age, weight, height, popliteal height, popliteal sacrum distance, among others. These measurements allowed to characterize the children of the sample and to make a comparison with the results of other investigation during the decade of the eighties, finding that the children of the present investigation are higher and heavier to a 3,10% and a 23.3% respectively. It was also found that the children of the private schools had a higher weight and size than the children of the public schools. The dimensional information of the school furniture was also recorded to compare it with the requirements of the Covenin Norms 1650-89 and with the anthropometric requirements of the children of the study, finding that the used writing desks do not fulfil the requirements of the Covenin norms mentioned, nor are ergonomically comfortable with the dimensional requirements of the children of the sample. It was also found that 67% of the evaluated classrooms there are children who carry a weight higher than 10% of their corporal weight suggested by the American Pediatric Associatio.
