Title Work activity and coronary heart mortality.
Bibliographic information Mar. 1975, Vol.292, No.11, p.545-550. Illus. 34 ref.
Abstract 6,351 longshoremen were followed up for 22 years or until death or the age of 75. Their longshoring experience was computed in terms of work-years according to categories of high, medium and low caloric output. An age-adjusted coronary death rate of 26.9 per 10,000 work-years was found for the high activity category, compared with 46.3 and 49.0 for the medium and low categories. The rate of the sudden death syndrome was 5.6 in the heavy workers, 19.9 in moderate and 15.7 in light workers. Repeated bursts of high energy output establish a plateau of protection against coronary mortality. Mechanisms that may explain this finding are discussed.
