Heart Disease and Occupational Risk Factors in the Canadian Population: An Exploratory Study Using the Canadian Community Health Survey

BACKGROUND: The objective of this study is to find temporal trends in the associations between cardiovascular disease and occupational risk factors in the context of the Canadian population. METHODS: Population data were analyzed from the Canadian Community Health Survey (CCHS) collected between 2001 and 2014 for trends over time between heart disease and various occupational risk factors: hours worked, physical exertion at work, and occupation type (management/arts/education, business/finance, sales/services, trades/transportations, and primary industry/processing). RESULTS: We found no significant difference in the average number of hours worked/wk between individuals who report having heart disease in all years of data except in 2011 (F 1,96 = 7.02, p = 0.009) and 2012 (F 1,96 = 8.86, p = 0.004). We also found a significant difference in the degree of physical exertion at work in 2001 (F 1,79 = 7.45, p = 0.008). There were statistically significant results of occupation type on self-reported heart disease from 2003 to 2014. CONCLUSION: Canadian data from the CCHS do not exhibit a trend toward an association between heart disease and the number of hours worked/wk. There is an association between heart disease and physical exertion at work, but the trend is inconsistent. The data indicate a trend toward an association between heart disease and occupation type, but further analysis is required to determine which occupation type may be associated with heart disease.

Study on the possible effects of psychosocial factors on the development of coronary artery disease / 中国心理卫生杂志

Compared with 165 subjects without coronary artery disease(CAD),125 CAD pa-tients diagnosed bycoronary arteriography were investigated on the possibld relationship among psy-choosocial factors,including occupation,negative life events,type A behavior,and indexes of bloodlipid and blood rheology.The results showed that occupation type was one of the significantly correatesto the indexes of blood-lipid metabalism and blood rheology.The changes of neuroendocrinology andblood rheology following the occurrence of negative life events were correlated with the onset of lethalCAD.The physical and chemical indexes of hematology observed in subjects with Type A behaviorwere associated with atherogenesis and the pathogenesis of CAD.
