Association between occupational physical activity and myocardial infarction: a prospective cohort study
Why the study?
Does high occupational physical activity reduce incident myocardial infarction in employees without prior myocardial infarction?
Population
9,961 employees with no history of myocardial infarction from the Swedish Work, Lipids and Fibrinogen study.
Comparison
High occupational physical activity vs Low occupational physical activity
Design
Cohort
Follow-up
mean 13.1 years

Implication
High occupational physical activity should not yet inform MI prevention; leaves open its role pending randomized evidence.
Structured PICO
Does high occupational physical activity reduce incident myocardial infarction in employees without prior myocardial infarction?
P
Population
9,961 employees (6,849 men, 3,112 women, mean age 42.7 years) with no history of myocardial infarction from the Swedish Work, Lipids and Fibrinogen (WOLF) study.
I
Intervention
High occupational physical activity (standing and walking more than 50% of working day, or lifting/carrying)
C
Comparator
Low occupational physical activity (seated more than 50% of their working day)
O
Outcome
Incident myocardial infarctionhard clinical
Occupational physical activity alone does not appear sufficient to reduce the risk of incident myocardial infarction in the general working population.
