OBJECTIVE: To investigate the association between behavioral risk factors, specifically
postural habits, with the presence of structural changes in the spinal column of
children and adolescents. METHODS: 59 students were evaluated through the self-reporting Back Pain and Body Posture
Evaluation Instrument and spinal panoramic radiographic examination. Spine
curvatures were classified based on Cobb angles, as normal or altered in the
saggital plane and as normal or scoliotic in the frontal plane. Data were analyzed
using SPSS 18.0, based on descriptive statistics and chi-square association test
(a=0,05). RESULTS: The prevalence of postural changes was 79.7% (n=47), of which 47.5% (n=28) showed
frontal plane changes and 61% (n=36) sagital plane changes. Significant
association was found between the presence of thoracic kyphosis and female gender,
practice of physical exercises only once or twice a week, sleep time greater than
10 hours, inadequate postures when sitting on a seat and sitting down to write,
and how school supplies are carried. Lumbar lordosis was associated with the
inadequate way of carrying the school backpack (asymmetric); and scoliosis was
associated wuth the practice of competitive sports and sleep time greater than 10
hours. CONCLUSIONS: Lifestyle may be associated with postural changes. It is important to develop
health policies in order to reduce the prevalence of postural changes, by
decreasing the associated risk factors.
