title: [The effects of three kinds of biochemical indices on evaluation of occupational stress].
abstract: OBJECTIVE
  To study the feasibility of monoamine neurotransmitters, serum glucose, serum glycerinate and cholesterol as objective indices for evaluating occupational stress.
  
  
  METHODS
  Job stressors, modifiers, job strains in 844 people with four kinds of occupation were investigated, and the concentration of monoamine neurotransmitters, glucose, glycerinate and cholesterol in blood were detected at the same time. The methods of multiple stepwise regression and covariance analysis were used to analyze the data.
  
  
  RESULTS
  There was close relationship between monoamine neurotransmitters and job stressors, the forecast of the equation of 5-hydroxytryptamine (5-HT), dopamine (DA) and norepinephrine (NE) was 0.7238, 0.5703, 0.4438 respectively, the critical values of them were 804.00, 226.00 and 275.00 ng/ml respectively. There was a little contribution of job stressors to the equation of glucose, glycerinate and cholesterol, the critical values were 6.40, 2.51 and 5.92 mmol/L respectively.
  
  
  CONCLUSIONS
  Monoamine neurotransmitters may be a direct objective evaluating indices. Sugar, glycerinate and cholesterol may be an indirect objective indices.
