  Background: Growing evidence links shift work to cardiovascular disease. Our objective was to examine whether long-term shiftwork is associated with poor cardiovascular health (CVH) among police officers. Methods: Participants were 408 officers enrolled in the Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study (2004-2009). Electronic work history records, from 1994 to date of examination, were used to determine the dominant shift schedule as day, afternoon, or night. CVH was assessed according to American Heart Association criteria, where four behavioral (physical activity, smoking, diet, BMI) and three clinical (blood pressure, total cholesterol, fasting glucose) factors were classified as ideal, intermediate, or poor. Total CVH is considered poor if a participant has ≤ 1 ideal health metrics. Log-linear models were used to compare prevalence of poor CVH across shiftwork, by estimating prevalence ratios (PRs) using the day shift as the referent category. Results: The study sample consists of officers with mean age of 42-years (SD=8.4). The majority were men (75%), white (80%), married (75%), and patrol officers (66%). Prevalence of ideal CVH were highest for never-smokers/quit for >1-year (81%), low fasting glucose (74%), high physical activity (63%) and lowest for low cholesterol (40%), lower blood pressure (37%), low BMI (18%), proper diet (0%). The prevalence of poor CVH varied significantly across shift (day=6.7%, Afternoon=10.5%, and night=11.8%). After adjusting for age, prevalence of poor CVH was two times higher in afternoon shift officers (PR=2.41, 95%CI: 1.12-5.15) and three times higher in night shift officers (PR=3.04, 1.31-7.02), compared to day shift. Adjustment for further covariates (gender, race, and police rank) attenuated the association [night vs. day: PR=2.11 (0.82-5.43), afternoon vs. day: PR=1.67 (0.75-3.71)]. Prevalence of poor blood pressure was twice higher in night shift officers compared to day shift (PR=2.11, 1.14-3.92). Conclusions: Poor CVH may be associated with shift work and future prospective studies are warranted. [Description provided by NIOSH]
