Associations of work hours with carotid intima-media thickness and ankle-brachial index: the Multi-Ethnic Study of Atherosclerosis (MESA).

ABSTRACT:

Objectives

Long working hours may be associated with cardiovascular disease (CVD). The objective was to investigate cross-sectional associations of work hours with carotid intima-media thickness (CIMT) and ankle-brachial index (ABI).

Methods

Participants were 1694 women and 1868 men from the Multi-Ethnic Study of Atherosclerosis. CIMT and ABI were measured using standard protocols. Information on work hours was obtained from questionnaires. Mean values of CIMT and ABI were examined across five categories of hours worked per week (≤20, 21-39, 40, 41-50 and >50) using analysis of variance/analysis of covariance. p Values for trend were obtained from linear regression models.

Results

Mean age of participants was 56.9±8.4 years; 52.4% were men. Distinct patterns of associ
