Abstract:
OBJECTIVES: To reveal the influence of job stress change on body mass index (BMI) and waist circumference in white-collar male workers. METHODS: A total of 277 male workers in a Korean R&D company were enrolled between 2008 and 2010. Baseline and follow-up data were collected with structured self-administered questionnaires and anthropometric measurements by nurses. The questionnaire survey included general and work-related characteristics and the Korean Occupational Stress Scale-Short Form (KOSS-SF). The job stress scores in each examination were dichotomized at the median values for the Korean workers and categorized into four groups as follows: Group I: Both low job stress (2008, 2010), Group II: High job stress (2008) & low job stress (2010), Group III: Low job stress (2008) & high job stress (2010), Group IV: Both high job stress (2008, 2010). Multiple logistic regression modeling was used to determine the influence of job stress change on BMI and waist circumference. RESULTS: The adjusted odds ratio for the change in waist circumference above the 75th percentile for Group IV in 'job demand' increased more than in Group I (OR = 2.54 95% CI=1.06~5.55). Also, Group IV in 'job demand' has higher odds ratio for change in BMI above the 75th percentile than Group I (OR=2.25 95% CI=1.01~5.00). Adjusted odds ratios comparing Group II to Group I for the change in waist circumference above the 75th percentile were 0.36 (95% CI=0.15~0.87) in 'inadequate social support', 0.12 (95% CI=0.02~0.98) in 'lack of reward', 0.25 (95% CI=0.08~0.80) in 'total score', respectively. CONCLUSIONS: These results suggest that sustained high job control is a risk factor for abdominal obesity and weight gain. Also, diminished job stress has a negative influence on change in abdominal obesity. Further studies are required to establish job stress intervention plans.
