Abstract
Our aim was to investigate the impact of shiftwork on changes in central retinal arteriolar equivalent (CRAE), a measure of arteriolar width, and central retinal venular equivalent (CRVE), a measure of venular width, over five years. Participants were 117 officers (72.7% men) examined at the first (2011-2014) and second (2015-2019) follow-up examinations of the Buffalo Cardio-Metabolic Occupational Police Stress study. Shiftwork data were obtained from City of Buffalo, NY payroll records. Retinal diameters were measured using a standardized protocol. ANCOVA was used to compare mean change in CRAE and CRVE between the two examinations across shiftwork categories. Among men only, those who worked ≥70% hours on day shift had a larger decrease in mean CRAE (-7.13±2.51) compared to those who worked <70% day (-0.08±0.96); p=0.011. Among patrol officers, those who worked ≥70% day had a larger decrease in CRAE compared with those who worked <70% day; p=0.015. Also, officers who worked ≥70% day had an increase in mean CRVE (µm) (4.56±2.56) compared to those who worked <70% (-2.32±1.32); p=0.027. Over the five-year period, we observed adverse changes in arteriolar and venular diameters among officers who worked ≥70% on day shift. Results should be interpreted with caution due to small sample sizes.
