title: [Effect of occupational stress on menses and sex hormones of female knitting workers].
abstract: OBJECTIVE
  To investigate the effect of occupational stress on menses and sex hormones.
  
  
  METHODS
  415 female knitting workers were investigated using the generic job stress questionnaire. Their venous blood were collected and the six sex hormones were detected by using radio-immune method. The different rate of abnormal menses and sex hormones level between different stress degree groups were analyzed.
  
  
  RESULTS
  The abnormal rate of menses, menstrual blood volume, menstrual cycle, menstrual period was 36.24%, 19.80%, 14.43%, 11.41% respectively. The prevalence rate of dysmenorrheal and premenstrual syndrome was 1.01% and 29.19% respectively. The more depression, the higher menses disorders in non-intrauterine device (IUD) group. The more job demands, the higher daily stress in IUD group while the longer work time, the more abnormal menstrual period in two groups. More physical symptoms and deeper depression in non-IUD group were related to higher abnormal rate of menstrual blood volume. The level of blood E2 was lower in the group of prolonged work-time than that of in normal work-time group. The increasing FSH level and decreasing T level was associated with higher job demands. Multiple factor analysis showed that physical symptom, control of resource and negative life affairs were the risk factors of menses disorder; The physical symptom was the risk factor of menstrual blood volume; More physical symptoms, less positive feeling and shift were the risk factors of premenstrual syndrome; Less positive feeling was the risk factor of menstrual cycle; Prolonged daily work-time was the risk factor of menstrual period.
  
  
  CONCLUSIONS
  Higher stress degree can lead to higher FSH and E2 and lower T level,and induce menses disorder.
