Title Risk of ischemic heart disease among primary aluminium production workers
Bibliographic information 1988, Vol.13, No.6, p.659-666. 11 ref.
Abstract The risk of ischaemic heart disease (IHD) has been studied in relation to working conditions encountered in a primary aluminium smelter employing over 6,000 men. During the period 1975-1983, 306 new cases of IHD were identified which were matched with 575 referents. Results showed that white collar workers had a significantly lower risk of IHD (odds ratio 0.47, 95% confidence interval 0.31-0.70). Among blue collar workers, a significantly higher risk was observed for workers in the reduction division of the plant (OR = 1.72, CI = 1.09-2.97) including, in particular, Soderberg (OR = 1.71, CI = 1.07-2.72) and prebake (OR = 2.26, CI = 1.27-4.02) potroom workers. The risk of IHD did not increase with the length of time worked in these occupations. The search for associations (among blue collar workers) of risk with 9 specific contaminants (benzene soluble material, fluoride, total dust, sulfur dioxide, carbon monoxide, thermal stress, noise, physical load, and mental load) proved inconclusive, with no association reaching statistical significance.
