OBJECTIVE: Evaluate the posture of students from a public school in Brazil and to identify the differences between normal deviation during growth and compensatory alterations. METHODS: Students from first to fourth grade of a public school in the city of Jaguariúna, São Paulo, Brazil, were evaluated. The students were positioned at sagital anterior and posterior coronal planes for postural assessment. Kendall points were used as the normal reference. RESULTS: 247 students were evaluated, 131 boys and 116 girls, and the main postural deviations found were: shoulder unbalance (50.2%), protracted shoulder (39.7%), abducted scapula (40.5%), knock-knee (29.6%), pelvic unbalance (21.5%), pelvic anteversion (19%), knee hyperextension (19%), medial rotation of hip (12.9%), protracted cervical (11.7%), head tilt (15.4%), thoracic hyperkyphosis (9.7%) and lumbar hyperlordosis (26.3%). CONCLUSIONS: A high incidence of postural alterations was detected in school children. Some of the postural alterations, such as abducted scapula, unbalance and protraction of the shoulders, knock-knee and lumbar hiperlordosis, normally occur and they are naturally corrected during growth. However, some postural problems, such as protraction and inclination of the cervical spine, were also prevalent and they require early intervention.
