  • Purpose
    The purpose of this study was to investigate the factors related to dyslipdemia and hypertension among male office workers.
  • Methods
    This study was a cross-sectional survey. The sample was 204 male office workers aged 30 to 62 years without cardiovascular disease and not taking medication for hypertension and dyslipidemia. Data were collected from November, 2011 to March, 2012. Dyslipidemia was examined by checking serum lipid profiles.
  • Results
    Dyslipidemia was related to career (adjusted OR 1.06, 95% CI 1.03~1.51), time spent at desk (adjusted OR 1.25, 95% CI 1.03~1.51), job stress of Q25-49 (adjusted OR 2.72, 95% CI 1.24~5.93), inactivity (adjusted OR 6.86, 95% CI 2.62~17.93), and snack intake frequency (adjusted OR 1.57, 95% CI 1.03~2.38). Hypertension was related to career (adjusted OR 1.07, 95% CI 1.01~1.14), heavy drinking (adjusted OR 5.00, 95% CI 1.25~20.04), and snack intake frequency (adjusted OR 2.10, 95% CI 1.33~3.34).
  • Conclusion
    Work and lifestyle-related factors were associated with dyslipidemia and hypertension in male office workers. These findings suggest that lifestyle intervention and improvement of working conditions are integral parts of cardiovascular disease prevention.
