Factores asociados al dolor musculoesquelético en población trabajadora chilena

Abstract

Objetive: Identify factors associated to pain due to work related activities, reported by chilean workers. Methods: We conducted an analysis of the First National Survey of Work Conditions, Work, Health and workers' Quality of Life, conducted in Chile in 2009-2010. The result variable was the reported number of body parts with pain due to work. The analysis included sociodemographic variables, working conditions, health behaviors, and personal variables. We conducted zero inflated Poisson regressions to estimate the contribution of the factors on reported pain. Results: One of every two workers reported pain. Women reported more pain than men (PR: 1.47), but this relationship diminished as age increased (PR: 1.37). Workers that were exposed to physical demands reported pain in 64% more body parts. Psychological demand, low social support in work, and low work autonomy were associated to more pain report (PR: 1.29, PR: 1.13, PR: 1.23 respectively). Conclusions: Gender and age are relevant factors associated to pain report due to work, even when adjusted for working conditions. Significant differences between age groups were identified.
