Impact of Shiftwork on Retinal Vasculature Diameters over a 5-Year Period: A Preliminary Investigation Using the BCOPS Study Data
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. The participants were 117 officers (72.7% men) examined at the first (2011-2014) and second (2015-2019) follow-up examinations in the Buffalo Cardio-Metabolic Occupational Police Stress study. Shiftwork data were obt…
Mental Health Treatment Reported by US Workers before and during the Covid-19 Pandemic: United States (2019–2020)
The COVID-19 pandemic introduced a significant and unprecedented exacerbation of community mental health challenges. We compared the prevalence of mental health treatment (MHT) before and during the COVID-19 pandemic among US workers. Self-reported MHT data (N = 30,680) were obtained from the Sample Adult data of the National Health Interview Survey (2019 and 2020). MHT was defined as having taken prescription medications for mental health issues…
Associations between adiposity measures and 25‐hydroxyvitamin D among police officers
OBJECTIVE: Studies show that serum levels of 25-hydroxyvitamin D (25(OH)D), a biomarker for vitamin D status, are lower in persons with higher adiposity levels and that police officers have been found to have a high prevalence of obesity. The purpose of this study was to examine relationships between several adiposity measures and 25(OH)D, and also compare those measures to determine the best one that predicts insufficiency of 25(OH)D (<20 ng/mL)…
Prevalence of workplace discrimination and mistreatment in a national sample of older U.S. workers: The REGARDS cohort study
Although workplace discrimination and mistreatment (WDM) has recently drawn widespread media attention, our understanding of the prevalence of these phenomena remains limited. In the current study, we generated national prevalence estimates of WDM from a community-based cohort of employed black and white men and women aged ≥48 years. Measures of WDM in the current job were obtained by computer-assisted telephone interview (2011-2013) involving di…
Association of occupational stress with waking, diurnal, and bedtime cortisol response in police officers
Higher stress ratings were related to blunted diurnal decline in cortisol, suggesting conventional and unexpected police stressors may result in HPA axis dysfunction. Future studies investigating possible associations between elevated cortisol and subclinical CVD are needed
Police stressors and health: A state-of-the-art review
PURPOSE –: The purpose of this paper is to provide a state-of-the-art review on the topic of police stressors and associated health outcomes. Recent empirical research is reviewed in the areas of workplace stress, shift work, traumatic stress, and health. The authors provide a comprehensive table outlining occupational exposures and related health effects in police officers. DESIGN/METHODOLOGY/APPROACH –: A review of recent empirical research on …
Police work stressors and cardiac vagal control
OBJECTIVES: This study examines relationships between the frequency and intensity of police work stressors and cardiac vagal control, estimated using the high frequency component of heart rate variability (HRV). METHODS: This is a cross-sectional study of 360 officers from the Buffalo New York Police Department. Police stress was measured using the Spielberger police stress survey, which includes exposure indices created as the product of the sel…
Leptin, adiponectin, and heart rate variability among police officers
Leptin levels were inversely associated with LF HRV, especially among officers with increased adiposity. Increased leptin levels may be associated with CVD-related health problems
The Association of Depressive Symptoms and Pulmonary Function in Healthy Adults
OBJECTIVE: Chronic lung disease is exacerbated by comorbid psychiatric issues and treatment of depression may improve disease symptoms. We sought to add to the literature as to whether depression is associated with pulmonary function in healthy adults. METHODS: In 2551 healthy adults from New York State, we studied the association of depression via the Center for Epidemiologic Studies Depression scale (CES-D) scale score and forced expiratory vol…
Adiposity, muscle, and physical activity: Predictors of perturbations in heart rate variability
Higher levels of physical activity, lower levels of markers for central adiposity and higher lean mass in the extremities predict higher levels of HRV in this population of police officers. This association between modifiable risk factors and markers for autonomic function suggest possible interventions that may improve health and performance
Associations between insulin and heart rate variability in police officers
In this cohort, insulin levels were inversely and significantly associated with both HF and LF HRV, especially among those with higher levels of obesity and lower levels of physical activity, suggesting associations with autonomic nervous system function. Prospective studies of this association in other populations are warranted
Area Under the Curve and Other Summary Indicators of Repeated Waking Cortisol Measurements
OBJECTIVE: To derive the area under the curve and related summary measures of stress from saliva samples collected over time and to provide insight into the interpretation of the derived parameters. In research designed to assess the health consequences of stress these samples are often used as a physiologic indicator of the responsiveness of the hypothalamic-pituitary-adrenal (HPA) axis. To make these repeated measurements of salivary cortisol m…
