title: [Characteristics of the stages of change in physical behavior of male workers suffering from impaired glucose tolerance].
abstract: OBJECTIVE
  The purpose of this study was to describe the characteristics of the stages of change in physical behavior of workers with diabetes and impaired glucose tolerance according to their dietary behavior, BMI, FBS, and HbA1c.
  
  
  METHODS
  The annual health checkup records of 15,317 male employees of an automobile corporation were examined. The stages of change in physical behavior were assessed through a self-reported questionnaire about "regular exercise" related to the five transformation stages and the date were used to analyze analyzes its relationship to dietary behavior, BMI, FBS, and HbA1c.
  
  
  CONCLUSIONS
  The older age groups reported that the time spent on the "Action" and the "Maintenance" stages increased gradually over time. From the results we deduced that activity in the 30-39-year-old age group is low, which may be due lifestyle influence. The groups with advanced HbA1c levels reported that the time spent on the "Action" and the "Maintenance" stages increased. This may reflect the effects of present health management and continued research on its effects is needed. Significant correlations between the stages of change for physical and dietary behavior were observed in every age group and in every HbA1c level group. Developing regular exercise habits was closely related to developing adequate dietary habits in every age group and in every HbA1c level group. The correlation between exercise and dietary habits is so strong that future research into the causes inhibiting individuals from developing regular exercise habits is needed for workers with diabetes and impaired glucose tolerance. Developing regular exercise habits did not have a significant relation to FBS disorders in the 30-39 yr old age group or obesity in any age group. The results suggest that the effect and the limit of the physical behavior can be appropriately guided, and the offer of that encourages and supports the maintenance of the education physical behavior established is important.
  
  
  CONCLUSIONS
  Health management systems for the prevention of diabetes mellitus should include independent education programs for encouraging regular exercise habits combined with diet programs in consideration of characteristics of the stages of change in physical behavior of working populations.
