Injury Epidemiology and Prevention

Low back pain (LBP) is a common complaint among children and adolescents and can negatively impact their physical and mental health. Although previous studies investigating the incidence of low back pain (LBP) in children and adolescents have been performed in high income countries, it is unclear whether countries such as Brazil would show similar incidence rates.To determine the incidence and to identify predictors of new episodes of LBP in high school students.This is a 1-year longitudinal study of high school students from public schools in the city of Bauru, Sao Paulo. Collected clinical data were: demographic and socioeconomic factors, information on the use of electronic devices, mental health status (the Strengths and Difficulties Questionnaires), level of habitual physical activity (Baecke Physical Activity Questionnaire), and incidence of LBP (measured with question about LBP in the past 12 months and the Nordic Musculoskeletal Questionnaire). Descriptive analysis and bivariate and multivariate logistic regressions were performed.The cumulative incidence of new LBP episodes for the total cohort of 757 high school students was 18.9% (95% CI: 16.2, 21.8). The cumulative incidence was 14.8% (95% CI: 11.7, 18.5) for male students and 24.1% (95% CI: 19.8, 29.9) for female students. Being a female student (OR = 1.78; 95% CI: 1.23, 2.59), sitting posture while using tablet (OR = 4.34; 95% CI: 1.19, 16.60), daily time spent on tablet (OR = 3.21; 95% CI: 1.41, 7.30), daily time spent on mobile phone (OR =1.49; 95% CI: 1.11, 2.00), lying posture while using mobile phone (OR = 1.49; 95% CI: 1.05, 2.12), and mental health status (OR = 2.81; 95% CI: 1.76, 4.48) were identified as predictor variables.Our findings showed that one in five high school students reported having a LBP episode over the last year. The predictors found to be associated with low back pain include those related to sex, time and posture while using electronic devices, and mental health status.
