Description:Background:
Long work hours may be associated with adverse outcomes, including cardiovascular disease. We investigated cross-sectional associations of current work hours with coronary artery calcification (CAC).
Methods:
Participants (n=3,046; 54.6% men) were from the Multi-Ethnic Study of Atherosclerosis. Number of hours worked in all jobs was obtained by questionnaire and CAC from computed tomography. The probability of a positive CAC score was modeled using log-binomial regression. Positive scores were modeled using ANCOVA and linear regression.
Results:
Sixteen percent of the sample worked over 50 hours per week. The overall mean CAC score was 5.2±10.0; 40% had positive scores. In fully-adjusted models, prevalence ratios were <40 hours: 1.00 (CI:0.88–1.12), 40:(ref.), 41–49:1.13 (CI:0.99–1.30), and ≥50:1.07 (CI:0.94–1.23) and longer current work hours were not associated with higher mean CAC scores [<40:56.0 (CI:47.3–66.3), 40:57.8 (CI:45.6–73.3), 41–49:59.2 (CI:45.2–77.6), ≥50:51.2 (CI:40.5–64.8); p=0.686].
Conclusions:
Current work hours were not independently associated with CAC scores.
