• Description:
  Purpose: Poor sleep quality and sleep duration have been shown to be associated with subclinical cardiovascular disease (CVD). Ankle brachial index (ABI), a common measure of peripheral artery disease (ABI <1.0), is a strong risk factor for CVD. Our aim was to investigate whether sleep duration and quality are associated with ABI among police officers. Methods: Participants were officers who enrolled in the Buffalo Cardio-Metabolic Occupational Police Stress study (2010-2015). Objective sleep measures were obtained from actigraphy. ABI was calculated as highest systolic blood pressure (SBP) of right ankle divided by highest SBP of right arm. Mean values of ABI were compared across categories of the sleep measures using ANOVA/ANCOVA. Results: Officers (n=210; 70% men) ranged in age from 28 to 65 years (mean +/- SD=46.3 +/- 6.7 years). Thirty (14.3%) officers had low ABI (<1.0). Sleep duration was significantly associated with ABI after adjustment for age, sex, physical activity, metabolic syndrome, high sensitivity C-reactive protein, and smoking status: <7 hours (mean ABI=1.062 +/- 0.010) vs. >/=7 hours (1.090 +/- 0.010); p=0.009. Race/ethnicity significantly modified this association (interaction p=0.012). Race-stratified analyses showed that the association between sleep duration and ABI was only significant among White/Hispanic officers; <7 hours (ABI=1.052 +/- 0.012) vs. >/=7 hours (1.093 +/- 0.011); p=0.002. Two measures of sleep quality (sleep efficiency and latency to persistent sleep) were not significantly associated with ABI. Discussion: Longer sleep duration (i.e., >/=7 hours) was significantly associated with higher (i.e., better) mean ABI among White/Hispanic but not among African American officers. Reasons for the racial differences are unclear. [Description provided by NIOSH]
