The relationship of low-back pain, work history, work environment, and stress. A retrospective cross-sectional study of 38- to 64-year-old women

Abstract

The association between low-back pain (LBP) and different work factors was investigated in a retrospective cross-sectional study of a random sample of 1,760 38- to 64-year-old women. The life-time incidence of LBP was 66% and the prevalence was 35%. In a univariate analysis, eight work variables correlated to LBP viz. more forward bending, more lifting, more standing, more monotonous work, dissatisfaction with the work tasks, dissatisfaction with the work environment, a higher degree of worry, and fatigue at the end of the work day. In a covariate analysis, however, only the three psychological variables remained directly associated to LBP viz. dissatisfaction with the work environment, a higher degree of worry, and fatigue at the end of the work day.
