The relationship between the psychological stress of adolescents in school and the prevalence of chronic low back pain: a cross-sectional study in China

Background Accumulating evidence supports an association between an unhealthy mental state and low back pain (LBP). However, the degree of the association between mental health and chronic low back pain (CLBP) in the general population is poorly understood. The objective of this study was to analyze the incidence of CLBP in Chinese college students and to examine the association between students’ unhealthy mental states and the prevalence of CLBP.
