title: [Analysis of colliery migrant workers quality of life and its influential factors].
abstract: OBJECTIVE
  To study colliery migrant workers' quality of life and related influential factors.
  
  
  METHODS
  By multi-stage random sampling, 1161 colliery migrant workers were collected and assessed with the SF-36 and the self-made questionnaires. Multiple covariance and optimal scaling regression statistical methods were used to analyze the data.
  
  
  RESULTS
  Physiological and mental health filed of colliery migrant workers, the physical functioning (PF), role-physical (RP), bodily pain (BP), general health (GH) and vitality (VT) score of those colliery migrant workers whose working age was less than 5 years higher than those over 10 years. The PF, RP, BP, GH, mental health (MH), VT and SF based within the health group, resulted in a higher score, compared to those who suffer from chronic diseases. The RP, GH and social functioning (SF) based within the mild labor intensity, resulted in a higher score, compared to those who severe labor intensity. The PF and RE based within the non-initial coal mine work, resulted in a higher score, compared to those who initial coal mine work. The PF, BP and VT based within the pre-employment physical examination, resulted in a higher score, compared to those who non pre-employment physical examination. The MH based within the smoking, resulted in a higher score, compared to those who no smoking. These differences were statistical significance (P < 0.05). Multiple factors analysis showed that working age (F = 19.26, P < 0.01), chronic diseases (F = 13.89, P < 0.01) and initial coal mine work (F = 8.48, P < 0.01) were the influential factors of physical component summary (PCS). Labor intensity (F = 5.90, P < 0.01), smoking (F = 10.45, P < 0.01) and chronic diseases (F = 7.91, P < 0.01) were the influential factors of mental component summary (MCS).
  
  
  CONCLUSIONS
  There are some difference in individual characteristics (e. g. working age). Working age, chronic diseases, initial coal mine work, labor intensity, smoking are the influential factors for quality of life.
