Study objective : To determine the association between adverse psychosocial characteristics at work and risk of first myocardial infarction in the occupational categories of Kaunas men, Lithuania. Design : The analysis was based upon a case-control study among full time working men in the general population of Kaunas. Outcome measure : First non-fatal myocardial infarction diagnosed in 2001-2002. The Swedish version of the demand-control questionnaire was used to examine the effect of job control and demands. Setting : Kaunas, the second largest city in Lithuania, a former socialist country in a transition market economy. Participants : Cases were 203 men 25-64 years of age with a first non-fatal myocardial infarction and controls were 287 men group randomly selected from the study base. Main results : Low job control had a significant effect on myocardial infarction risk in the general 25-64 year old Kaunas male population (OR=2.68 ; 95% Cl 1.68 to 4.28) after adjustment for age and socioeconomic status. Low job control was a risk factor in the occupational categories of the increased myocardial infarction risk (1st occupational category-legislators, senior officials and managers and the 8th-plant and machine operators and assemblers ; OR=2.78 ; 95% Cl 1.31 to 5.93 and 2.72 ; 95% Cl 1.56 to 4.89, respectively, after adjustment for age and socioeconomic status). Though the adjusted odds ratio estimates were significantly high for the rest of the occupational categories (2nd-professionals, 3rd-technicians and associate professionals, and 7th-craft and related trades workers). Conclusions : The association between low job control and first myocardial infarction risk was significant for all occupational categories of Kaunas men.
