Prevalence and factors associated to back pain in adults from the northeast of São Paulo, Brazil: a population-based study

Abstract

Introduction: Back pain has become a serious public health problem. Objective: To determine the prevalence of back pain in a population-based sample of subjects over 20 years old living in the city of Bauru (São Paulo, Brazil) and to analyze the associations to variables-sociodemographic, ergonomic and lifestylerelated -and to morbidity. Methods: a cross-sectional study which evaluated 600 adults over 20 years old, both gender and living in the city. We used a structured protocol and the Nordic questionnaire. Also, we developed a descriptive analysis, bivariate and multivariate by binary logistic regression. Results: The prevalence of back pain was of 50.3% (CI 46.3 to 54.3), since 42.3% (CI 36.9 to 48.0) in men and 57.6% (CI 51.9 to 63.0) in women, with statistical significant difference (p = 0.001). Different variables remained in final models when assessed by gender. For male to be widowed and divorced and smoking habits and, for women to be widowed and divorced, to work in seated position and to perform occupational activities that demand carrying and lifting weight. Conclusion: We verified high prevalence in back pain in the population

Repeatability and reproducibility of a topographic system to evaluate the spine

“…Problems related to posture and spine pain are becoming increasingly common in today's society. Such problems are observed more frequently in the economically active population, hampering individuals' social and professional performance (Azevedo et al, 2020;Mendonça et al, 2020;Moreira et al, 2017;Sampaio et al, 2016;Santos et al, 2017;Vitta et al, 2017). Dorsal kyphosis and lumbar lordosis are some of the postural changes observed (Sampaio et al, 2016;Santos et al, 2017;Vitta et al, 2017).…”

Dorsal kyphosis and lumbar lordosis are some of the postural changes observed (Sampaio et al, 2016;Santos et al, 2017;Vitta et al, 2017). Although problems related to postural changes are widespread, most studies use visual and qualitative postural evaluation for collecting and analyzing data (Barreto et al, 2018;Noll et al, 2012;Sampaio et al, 2016).…”

“…However, this method has some disadvantages, such as the patient's exposure to ionizing radiation and poor image quality, which can make it difficult to perform the assessment and analyze the images (Bacchi et al, 2013;de Oliveira et al, 2012;Furlanetto et al, 2012). In addition to being a high-cost examination (Sampaio et al, 2016;Santos et al, 2017;Vitta et al, 2017), which limits access for some individuals, X-ray can cause damage to the patient's health due to the frequent exposure to radiation (Teixeira & Carvalho, 2007).…”
