Abstract
Introduction: Low back pain is frequent among schoolchildren and the variables related to high intensity and high back frequency are important predictors for the increase of such complaints in adulthood. Objective: To determine the high intensity and high frequency of low back pain and its associated factors in high school students. Methods: This cross-sectional study included 760 students (319 boys and 441 girls) who reported low back pain. Demographic, socioeconomic, electronic devices, habitual physical activity practice, mental health, and high frequency and high intensity low back pain data were collected. Descriptive analyzes and bivariate and multivariate logistic regressions were used. Results: Of the total number of subjects with low back pain, 14.6% reported high frequency of pain, being 36.9% boys and 63.1% girls, while 42.6% reported high intensity, being 35.8% boys and 47.2% girls. The variables associated with the high frequency of low back pain were altered mental health, posture lying on the use of tablet, time of daily use of the cell phone and distance of the screen to the eyes of the computer user, while the female sex, mental health problem, posture lying on the use of cell phone and the distance of the screen to the eyes of the computer user with severe intensity of low back pain. Conclusion: The demographic factors and related to the use of electronic devices were associated with high intensity and high frequency of low back pain.

Low back pain is frequent among schoolchildren and the variables related to high intensity and high back frequency are important predictors for the increase of such complaints in adulthood
The variables associated with the high frequency of low back pain were altered mental health, posture lying on the use of tablet, time of daily use of the cell phone and distance of the screen to the eyes of the computer user, while the female sex, mental health problem, posture lying on the use of cell phone and the distance of the screen to the eyes of the computer user with severe intensity of low back pain
Considering the factors associated with Low back pain (LBP)-FH and LBP-FH pain described in the literature, the present study proposed the organization of these determinants into four levels: Level 1 - gender, age, skin color, socioeconomic and marital status; Level 2 - health variable; Level 3 - variables related to the use of electronic devices; Level 4 - habitual practice of insufficiently active physical activity
Summary
Low back pain is frequent among schoolchildren and the variables related to high intensity and high back frequency are important predictors for the increase of such complaints in adulthood. Objective: To determine the high intensity and high frequency of low back pain and its associated factors in high school students. Conclusion: The demographic factors and related to the use of electronic devices were associated with high intensity and high frequency of low back pain. Low back pain (LBP) is a public health problem, with a high prevalence in school-age children and adolescents. Its presence at this stage of school development increases the risk of such complaints in adulthood. In Brazil, some localities have reported the prevalence of LBP, as follows: 13.7% in Pelotas5, 46.6%, in Garibaldi6, 27.7% in São Leopoldo[7], and 13.4% in Porto Alegre[8], state of Rio Grande do Sul; 42.1% in Petrolina[9] and 46.9% in Recife[10], state of Pernambuco; and 32.9% in the state of Piauí[11].
