Truck driving and risk of myocardial infarction.
OBJECTIVE
To investigated the effect ischemic heart disease of risk factors on elevated first myocardial infarction risk among truck drivers.


METHODS
We carried out a case-control study among men aged 25-64, Kaunas in 1997-2000. We identified myocardial infarction cases (n = 448) from the myocardial infarction hospital register (International Classification of Diseases, 10-th revision, code 121). Controls (N = 1777) were selected on the basis of age, gender and city district of residence. We obtained information on sociodemographic, psychosocial and behavioral factors. We used the International Standard Classification of Occupations (ISCO) to code for occupations and conducted logistic regression analysis to evaluate the effect of ischemic heart disease risk factors on myocardial infarction risk for truck drivers.


RESULTS
We found that truck rivers were at increased risk for the development of first myocardial infarction (age-adjusted odds ratio 2.36; 95% CI 1.67-3.35). After adjustment for smoking, hypertension, obesity, stress the odds ratio remained stable (2.26; 95% CI 1.58-3.24) as compared to other employed men. The logistic regression analysis within the subpopulation of truck drivers showed that the odds ratio for arterial hypertension was 3.20, for smoking--2.48. The effect of obesity and stress decreased to insignificant level.


CONCLUSIONS
Truck drivers are at increased risk for the development of first myocardial infarction. Arterial hypertension and smoking are significant risk factors of myocardial infarction for truck drivers.
