Risk factors associated with back pain vary in different countries. Given the lack of studies in Latin America, our study aimed to assess back pain and its associated factors for six years in Southern Brazilian school children. All children attending the fifth grade of Teutônia, Brazil, were invited to participate in the study. Only schoolchildren who did not report back pain were included in the first assessment. The schoolchildren completed the Back Pain and Body Posture Evaluation Instrument (BackPEI) during three assessments (2011, 2014, and 2017). BackPEI assesses the presence of back pain and possible associated risk factors (postural, behavioral, and sociodemographic). Generalized estimated equations (GEE) were used to perform a Poisson regression model with robust variance for longitudinal analysis. After six years of follow-up, 75 schoolchildren completed all the assessments. The risk factors associated with back pain were spending more than six hours daily watching television, lifting objects from the ground adopting an inadequate posture, using another backpack type different from those with two straps, and carrying a backpack in an asymmetric way. These results are important in guiding the planning of public policies to minimize this public health problem.
