Objective: The purpose of this study was to estimate the prevalence of adolescent idiopathic scoliosis (AIS), and back pain and its risk factors, in schoolchildren from the semiarid region of Brazil. Methods: A total of 520 adolescents aged 10 to 16 years old were assessed. The students were administered the self-reported Back Pain and Body Posture Evaluation Instrument questionnaire. The screening for AIS included measuring the angle of trunk rotation using a scoliometer in the Adams forward-bend test. Participants with an angle of trunk rotation ≥ 7° were referred for radiography. The prevalence ratio was estimated by multivariable analysis using a Poisson regression model (α = 0.05). Results: Among the participants, 3.1% (95% confidence interval, 3.2%-6.9%) had a confirmed AIS diagnosis: 1.9% girls and 1.1% boys. There was no difference between boys and girls in AIS prevalence. The prevalence of back pain in the previous 3 months was 63.7% (95% confidence interval, 59.5%-67.7%), at a moderate level (visual analog scale = 3.83; 95% confidence interval, 3.57-4.08). Multivariable analysis showed that back pain is associated with postural variables, sex, and age. Conclusion: The prevalence of AIS in the semiarid region of Brazil was 3.1%, and that of back pain was 63.7%. Only body mass index was different between adolescents with and without AIS, with those with AIS having a lower mean body mass index. Back pain was higher in girls and increased in older adolescents. Furthermore, behavioral and postural habits and hereditary factors were associated with an increased chance of back pain.
