Photographs were taken with and without backpack, which then were evaluated by the Software postural assessment (SAPO). Numerical variables were analyzed by paired Student t test and qualitative variables by chi-square. Results: The most frequent type of backpack was the wheels, the average weight of the backpack was 11% of the average body weight of children and 60.3% of these carry a book or two. Significant changes were: frontal angle of the right leg, anterior translation of the head, backwards of the head, trunk  extension, posterior tilt of the body and anteversion of the pelvis.
