Abstract

Objective: Beside the well-established biological and behavioral risk factors, psychosocial factors have been accepted as important risk factors for coronary heart diseases CHD . While there is abundant evidence for the association between job strain and CHD in developed countries, more research needed on this association in developing countries. This study aims to examine the association between job strain and the risk of CHD and metabolic syndrome among the 30–64-year-old employed individuals.Methods: This is a population-based cross-sectional study. The study sample was derived randomly from the employed individuals aged between 30 and 64 participated in baseline Balcova Heart Study. Karasek’s demand-control-support questionnaire was applied to measure job strain. Presence of metabolic syndrome and Framingham risk score were main dependent variables. 191 female and 216 male participants were included in the analyses. Pearson chi-square test, ANCOVA and logistic regression analyses were used.Results: Women were found to have higher education levels, have more white-collar jobs, and have better economic status perception than men. 20% of men and 18% of women have been working in high-strain jobs. There was significant association of job strain with neither the Framingham risk score nor metabolic syndrome. The adjustments for education, age, and occupation did not alter the results. The interaction between the social support and job strain was also not significant.Conclusion: Job strain did not have an impact on both the Framingham risk score and metabolic syndrome. Although psychosocial factors are known as important risk factors for CHD in developed countries, the evidence in developing countries is scarce
