Key result
Blue-collar work linked to ~5.3-fold higher risk of first non-fatal acute IHD.
Why the study?
Most studies on the relationship between work and acute ischemic heart disease were performed in western populations, and their applicability to Asian populations is largely unknown.

May link job categories to acute IHD in Taipei; leaves open whether associations extend Western findings or warrant practice changes.
BACKGROUND: Most studies of the relationship between work and acute ischemic heart disease (IHD) were performed in western populations, and the extent to which their findings hold in Asian populations is largely unknown. The purpose of this study was to examine the association between job categories and non-fatal, first episodes of acute IHD in Taipei, Taiwan. METHODS: A hospital-based, case-control design was used. Cases were patients with a first episode of non-fatal acute IHD who were admitted to the department of cardiology. Two controls without known cardiovascular disease were matched to each case for age, gender, and date of admission. A total of 119 cases and 238 controls were enrolled between April and September 2004. RESULTS: Compared with white-collar workers, blue-collar workers had a 5.3-fold (95% CI: 1.5, 18.5) increased risk of a first episode of non-fatal acute IHD, while self-employed workers and managers/professionals had a slightly lower odds ratio of 0.6 (95% CI: 0.1, 2.4) and 0.5 (95% CI: 0.1, 2.2), respectively. Hypertension, diabetes, obesity, physical inactivity, and sleep disturbance were significant risk factors for acute IHD. A clustering of the cardiovascular risk factors was found in blue-collar workers. CONCLUSIONS: Blue-collar workers had a 5.3-fold increased risk of a first event of non-fatal acute IHD compared with white-collar workers, and this increased risk was associated with a clustering of cardiovascular risk factors.

Chen et al. (2007) conducted a case-control in Acute ischemic heart disease (n=357). Blue-collar job category vs. White-collar workers was evaluated on First episode of non-fatal acute IHD (OR 5.3, 95% CI 1.5, 18.5). Being a blue-collar worker was associated with a 5.3-fold increased risk of a first episode of non-fatal acute ischemic heart disease compared with white-collar workers (OR 5.3; 95% CI 1.5-18.5).
