Abstract Defining the factors affecting spinal disorders in female students and the direct effects of carrying heavy loads, their weight and type during school years is the main reasons behind conducting such studies. In order to do so, the paper attempts to investigate the relationship between Kyphosis disorder and the weight of schoolbags and backpacks in female primary and high school students. Statistical population of this study included all 10324 female students aged between 7 and 17 in Bonab. Using Morgan table, 370 students were selected through random cluster sampling and the rate of their Kyphosis was measured using the checkerboard. SPSS 21 computer application was used to do statistical calculations and the data were analyzed through independent T and Chi-square tests. The study revealed that weight and type of a bag could affect creation and development of Kyphosis disorder. Moreover, the rate of Kyphosis in primary school students was much higher in girls carrying backpacks compared to the ones carrying handbags. Yet, the study failed to find a significant relationship between Kyphosis disorder and weight and type of bags in high school students. It seems as if, choosing proper type and weight for the backpack along with the time a female primary school student carries it must be reconsidered, decent corrective exercises ought to be prescribed and the proper basis for their physical activities has to be provided.
