摘要

Background: Although low back pain (LBP) is one of the common reasons for absenteeism in the coal mining industry, there is little epidemiological data about LBP in workers in the developing countries. The purpose of the present study is to determine the prevalence of LBP in coal miners in China and to examine associations between work-related factors and LBP.
