Objective Understanding workers' self-rated health situation and influencing factors after railway speedup, providing scientific basis for formulating relevant measures.
Methods Self-rated health measurement scales (SRHMS)were adopted as measurement tools. On-site investigations and tests were performed on 1 822 people in Shijiazhuang area from May to July in 2009, including attendants of electric locomotive carriages, clerks of ground service and clerks of passenger service.
Results The differences among scores of three self-rated health sub-scales and total scores of self-rated health scales showed statistical significances. Gender, age, level of education, marital status of the participants could affect the scores of three rated health sub-scales and the total score of self-rated health scales(P < 0.05). The total score of self-rated health scales and the scores of sub-scales were lowest in attendants of electric locomotive carriage. Attendants, male, age, marital status, irregular working times, long time operation, unfamiliar with new technology and equipment, working at night infrequently were inversely proportional to the score of self-rated health in multiple linear regression analysis. But education was proportional to the score of self-rated health.
Conclusion The level of physical heath of railway workers in key sectors was low. The self-rated health situation related to job title, age, gender, education, martial status, irregular working time, long time operation, unfamiliar with new technology and equipment, working at night infrequently.
