Dying for the job: police mortality, 1950-2018.

Purpose ­: This study is a mortality assessment on police officers (68-years, 1950-2018) and includes all causes of death. Design/methodology/approach ­: The authors investigated 1,853 police deaths (1950-2018) using sources of mortality that included the National Death Index, NY State, and available records from the Buffalo NY police department. Standardized Mortality Ratios were calculated. Death codes were obtained from 8th and 9th International Classification of Disease revisions in accordance with the year of death. Findings ­: Compared to the US general population, white male police officers from 1950-2018 had elevated mortality rates for some causes of death, including diseases of the circulatory system, malignant neoplasms, cirrhosis of the liver, and mental disorders. Black and female officers had lower mortality rates for all causes of death compared to the general population. Research limitations/implications ­: The findings of elevated risk for chronic disease among police need to be studied in relation to stress, lifestyle, and exposure to chemical and physical agents. There is a special need to further study officers from minority populations as larger samples become available. Practical implications ­: The results of this study will provide police and occupational health practitioners with objective evidence to determine the health impact of work on law enforcement officers. Originality/value ­: This study is longest running mortality assessment on police officers ever conducted (1950-2018) and includes white, black, and female officers.

Adverse childhood experiences and police mental health.

Purpose ­: The purpose of this study is to examine cross-sectional associations between adverse childhood experiences (ACEs) and mental health among police officers. Design/methodology/approach ­: The sample was from the Buffalo Cardio-Metabolic Occupational Police Stress study data (132 male and 51 female officers). Standardized surveys were administered to participants. Regression coefficients were obtained from models adjusted for age, sex, race and alcohol intake. All statistical tests were performed using a statistical significance level at p < 0.05. Findings ­: Regression analyses showed significant positive associations between ACEs and mental health (Posttraumatic Stress Disorder [PTSD]: ß = 1.70, p < 0.001 and depressive symptoms: ß = 1.29, p < 0.001). Resiliency significantly modified the association between ACEs and PTSD. A positive and significant association was observed among officers with lower resiliency (ß = 2.65, p < 0.001). The association between ACEs and PTSD was stronger among male officers compared to females (ß = 2.66, p < 0.001 vs. ß = 0.59, p ≤ 0.248, respectively). Research limitations/implications ­: Child abuse and development of PTSD or depression could not be traced through time as this was a cross-sectional study. Recall bias may affect results. Practical implications ­: PTSD and depression associated with ACEs can affect the interpretation of threat and can exacerbate emotional regulation in officers. An inquiry should be expanded regarding work assignments of victimized officers, such as child exploitation and pornography investigation. Originality/value ­: There are few studies on ACEs and the mental health of police officers. The present study is among the first to associate multiple police mental health issues with ACEs.

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) among police officers in the Northeast area of the United States. METHODS: Participants were 281 police officers (71.5% men) from the Buffalo Cardio-Metabolic Occupational Police Stress Study (2011-2016). Associations of body mass index (BMI), abdominal height (AbHt), waist circumference (WC), WC-to-height ratio (WCHtR), percent body fat (PBF), and fat mass index (FMI) with 25(OH)D were obtained using multiple regression models after adjustment for age, race/ethnicity, season, multivitamin supplement use, and high-density lipoprotein cholesterol. The area under the curve (AUC) was used to evaluate the predictive ability of each adiposity measure to identify insufficient 25(OH)D concentrations. RESULTS: The prevalence of obesity (BMI ≥ 30) was 50.7% in men and 21.3% in women. Mean levels of 25(OH)D were 32.4 ng/mL in men and 34.4 ng/mL in women. After adjustment for covariates, PBF and FMI among men were inversely associated with 25(OH)D: PBF (ß ± SE = -2.40 ± 1.01, P = .018); FMI (-2.21 ± 0.93, .018). Among women, no adiposity measure was associated with 25(OH)D. PBF was the best predictor of insufficient 25(OH)D concentrations regardless of gender (AUC = 0.878). CONCLUSION: Adiposity measures were inversely associated with 25(OH)D, but differed between female and male officers.

Social avoidance in policing: Associations with cardiovascular disease and the role of social support.

PURPOSE: The purpose of this paper is to examine the association of social avoidance among police, cardiovascular disease (CVD) (metabolic syndrome (MetSyn)), and social support. DESIGN/METHODOLOGY/APPROACH: Participants were officers from the Buffalo Cardio-Metabolic Occupational Police Stress study (n = 289). Social avoidance (defined as the tendency to avoid social contact) and other subscales from the Cook-Medley Hostility Scale were analyzed. The mean number of MetSyn components across tertiles of the Cook-Medley scales was computed using analysis of variance and analysis of covariance. Social support was measured with the Social Provisions Scale, categorized as high or low based on the median. FINDINGS: The mean number of MetSyn components increased significantly across tertiles of social avoidance (1.51 ± 0.18, 1.52 ± 0.12, and 1.81 ± 0.12); the only Cook-Medley subscale that remained significantly associated with MetSyn following adjustment for age and gender. Participants high in social avoidance reported significantly lower social support (79.9 ± 8.5 vs 85.8 ± 8.6; p = 0.001). RESEARCH LIMITATIONS/IMPLICATIONS: The study is cross-sectional and therefore precludes causality. The authors were unable to determine the direction of associations between social avoidance and MetSyn. The measure of social support was unidimensional, including only perceived support; additional types of social support measures would be helpful. PRACTICAL IMPLICATIONS: This study suggests that occupational-based police social isolation is associated with health outcomes and lower support. Several suggestions are made which will help to improve communication between the police and public. Examples are the use of social media, training in communication techniques, and changing the police role to one of public guardians. ORIGINALITY/VALUE: Social avoidance is the least studied the Cook-Medley subscale associated with CVD. It is important for the health of officers to maintain a social connection with others.

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 self-evaluation of how stressful certain events were and the self-reported frequency with which they occurred. Vagal control was estimated using the high frequency component of resting HRV calculated in units of milliseconds squared and reported in natural log scale. Associations between police work stressors and vagal control were examined using linear regression for significance testing and analysis of covariance for descriptive purposes, stratified by gender, and adjusted for age and race/ethnicity. RESULTS: There were no significant associations between police work stressor exposure indices and vagal control among men. Among women, the inverse associations between the lack of support stressor exposure and vagal control were statistically significant in adjusted models for indices of exposure over the past year (lowest stressor quartile: M = 5.57, 95% CI 5.07 to 6.08, and highest stressor quartile: M = 5.02, 95% CI 4.54 to 5.51, test of association from continuous linear regression of vagal control on lack of support stressor ß = -0.273, P = .04). CONCLUSIONS: This study supports an inverse association between lack of organizational support and vagal control among female but not male police officers.

Leptin, adiponectin, and heart rate variability among police officers.

OBJECTIVES: Police officers have a high prevalence of cardiovascular disease (CVD). Reduced heart rate variability (HRV) is known to increase CVD risk. Leptin and adiponectin may be related to CVD health. Therefore, our objective was to investigate the relationship between these variables and HRV. METHODS: Leptin and adiponectin levels were measured in 388 officers from the Buffalo Cardio-Metabolic Occupational Police Stress study. HRV was assessed according to methods published by the Task Force of the European Society of Cardiology and the North American Society of Pacing Electrophysiology for measurement and analysis of HRV. Mean values of high-frequency (HF) and low-frequency (LF) HRV were compared across tertiles of leptin and adiponectin using analysis of variance and analysis of covariance; trends were assessed using linear regression models. RESULTS: Leptin, but not adiponectin, was significantly and inversely associated with HRV. Body mass index (BMI) and percent body fat significantly modified the association between leptin and LF (but not HF) HRV. Among officers with BMI < 25 kg/m(2) , leptin was not significantly associated with HRV. However, among officers with BMI ≥ 25 kg/m(2) , leptin was inversely associated with HRV, after adjustment for age, gender, and race/ethnicity; HF HRV, P = 0.019 and LF HRV, P < 0.0001. Similarly, among officers with percent body fat ≥ 25.5%, leptin and LF HRV showed significant, inverse associations (adjusted P = 0.001). CONCLUSIONS: 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.

Oxidative stress and reduced responsiveness of challenged circulating leukocytes following pulmonary instillation of metal-rich particulate matter in rats.

Welding fume is an exposure that consists of a mixture of metal-rich particulate matter with gases (ozone, carbon monoxide) and/or vapors (VOCs). Data suggests that welders are immune compromised. Given the inability of pulmonary leukocytes to properly respond to a secondary infection in animal models, the question arose whether the dysfunction persisted systemically. Our aim was to evaluate the circulating leukocyte population in terms of cellular activation, presence of oxidative stress, and functionality after a secondary challenge, following welding fume exposure. Rats were intratracheally instilled (ITI) with PBS or 2 mg of welding fume collected from a stainless steel weld. Rats were sacrificed 4 and 24 h post-exposure and whole blood was collected. Whole blood was used for cellular differential counts, RNA isolation with subsequent microarray and Ingenuity Pathway Analysis, and secondary stimulation with LPS utilizing TruCulture technology. In addition, mononuclear cells were isolated 24 h post-exposure to measure oxidative stress by flow cytometry and confocal microscopy. Welding fume exposure had rapid effects on the circulating leukocyte population as identified by relative mRNA expression changes. Instillation of welding fume reduced inflammatory protein production of circulating leukocytes when challenged with the secondary stimulus LPS. The effects were not related to transcription, but were observed in conjunction with oxidative stress. These findings support previous studies of an inadequate pulmonary immune response following a metal-rich exposure and extend those findings showing leukocyte dysfunction occurs systemically.

Associations between insulin and heart rate variability in police officers.

OBJECTIVE: Low heart rate variability (HRV) has been linked to cardiovascular disease. Our objective was to examine the cross-sectional association between insulin and HRV. METHODS: Insulin levels were measured in 355 nondiabetic officers from the BCOPS study, following a 12 h fast. HRV was performed according to methods published by the task force of the European Society of Cardiology and the North American Society of Pacing Electrophysiology for measurement and analysis of HRV. Mean values of high (HF) and low frequency (LF) HRV were compared across tertiles of insulin using ANOVA and ANCOVA; p-values were obtained from linear regression models. RESULTS: Higher mean levels of insulin were significantly associated with lower (i.e., worse) mean levels of HRV before and after risk-factor adjustment. The results for HF HRV (ms(2)) were as follows: 1st insulin (µU/ml) tertile (156.3; 95% confidence interval (CI) = 128.6-189.9); 2nd tertile (154.3; 95% CI = 124.3-191.5); 3rd tertile (127.9; 95% CI = 105.0-155.8), p for trend = 0.017. Results with LF HRV were similar to HF HRV. Insulin was also inversely and significantly associated with HRV among officers with BMI ≥ 25 kg/m(2), with ≥ 25.5% body fat, and among those who reported low (

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 obtained from the 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 shifts had a larger decrease in mean CRAE (-7.13 µm ± 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 to 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 shifts. The results should be interpreted with caution due to the small sample sizes.

Depressive symptoms and carotid artery intima-media thickness in police officers.

PURPOSE: Police work is a stressful occupation. Depressive symptoms, which may occur as a result of exposure to stressors in police work, have been known to be associated with an increased risk of cardiovascular disease. This cross-sectional study investigated the association between depressive symptoms and carotid artery intima-media thickness (CIMT) among police officers. METHODS: CIMT was measured with B-mode carotid ultrasonography. Depressive symptoms were measured using the Center for Epidemiological Studies Depression (CES-D) scale. Analyses of variance and covariance were utilized to examine the mean values of common CIMT (CCA IMT) and maximum CIMT (MMXIMT) across quintiles of depressive symptoms. RESULTS: Participants included 412 officers (mean age = 41 years). Hypertension status significantly modified the association between CES-D score and CIMT. The association between CES-D score and CCA IMT was statistically significant (adjusted P = 0.030) but only among officers without hypertension. The associations between CES-D score and MMXIMT were not significant among officers with or without hypertension. Our results also showed that among officers who reported poor sleep quality, mean levels of CCA IMT, and MMXIMT tended to increase as depressive symptoms increased. CONCLUSIONS: Depressive symptoms may be therefore be independently associated with CIMT, yet masked by hypertension. Even though sleep quality did not significantly modify the main association, our results also suggest that poor sleep quality may act synergistically with depressive symptoms to increase CIMT. Future prospective work would help to clarify these associations.

Life expectancy in police officers: a comparison with the U.S. general population.

Previous epidemiological research indicates that police officers have an elevated risk of death relative to the general population overall and for several specific causes. Despite the increased risk for mortality found in previous research, controversy still exists over the life expectancy of police officers. The goal of the present study was to compare life expectancy of male police officers from Buffalo New York with the U.S. general male population utilizing an abridged life table method. On average, the life expectancy of Buffalo police officers in our sample was significantly lower than the U.S. population (mean difference in life expectancy = 21.9 years; 95% CI: 14.5-29.3; p < 0.0001). Life expectancy of police officers was shorter and differences were more pronounced in younger age categories. Additionally, police officers had a significantly higher average probability of death than did males in the general population (mean difference = 0.40; 95% CI: 0.26-0.54; p < 0.0001). The years of potential life lost (YPLL) for police officers was 21 times larger than that of the general population (Buffalo male officers vs. U.S. males = 21.7, 95% CI: 5.8-37.7). Possible reasons for shorter life expectancy among police are discussed, including stress, shift work, obesity, and hazardous environmental work exposures.

Type I interferon and pattern recognition receptor signaling following particulate matter inhalation.

BACKGROUND: Welding, a process that generates an aerosol containing gases and metal-rich particulates, induces adverse physiological effects including inflammation, immunosuppression and cardiovascular dysfunction. This study utilized microarray technology and subsequent pathway analysis as an exploratory search for markers/mechanisms of in vivo systemic effects following inhalation. Mice were exposed by inhalation to gas metal arc - stainless steel (GMA-SS) welding fume at 40 mg/m3 for 3 hr/d for 10 d and sacrificed 4 hr, 14 d and 28 d post-exposure. Whole blood cells, aorta and lung were harvested for global gene expression analysis with subsequent Ingenuity Pathway Analysis and confirmatory qRT-PCR. Serum was collected for protein profiling. RESULTS: The novel finding was a dominant type I interferon signaling network with the transcription factor Irf7 as a central component maintained through 28 d. Remarkably, these effects showed consistency across all tissues indicating a systemic type I interferon response that was complemented by changes in serum proteins (decreased MMP-9, CRP and increased VCAM1, oncostatin M, IP-10). In addition, pulmonary expression of interferon α and ß and Irf7 specific pattern recognition receptors (PRR) and signaling molecules (Ddx58, Ifih1, Dhx58, ISGF3) were induced, an effect that showed specificity when compared to other inflammatory exposures. Also, a canonical pathway indicated a coordinated response of multiple PRR and associated signaling molecules (Tlr7, Tlr2, Clec7a, Nlrp3, Myd88) to inhalation of GMA-SS. CONCLUSION: This methodological approach has the potential to identify consistent, prominent and/or novel pathways and provides insight into mechanisms that contribute to pulmonary and systemic effects following toxicant exposure.

Pulmonary function and left ventricular mass in African Americans: the Atherosclerosis Risk in Communities (ARIC) study.

PURPOSE: Impaired pulmonary function has been associated with increased cardiovascular disease incidence and mortality. The objective of this study was to investigate associations between pulmonary function and left ventricular (LV) mass. METHODS: Participants were African American women (n = 1,069) and men (n = 555) aged 49-73 years, from the Atherosclerosis Risk in Communities study. Mean pulmonary function values at the first (1987-1989) and second (1990-1992) examinations were used. Echocardiograms were performed at the third and early in the fourth examinations (1993-1996). Analysis of covariance and linear regression were used to assess associations. RESULTS: Mean levels of LV mass decreased with increasing quintiles of forced expiratory volume in one second (FEV(1) ) among female never smokers (P = 0.039). Forced vital capacity (FVC) showed stronger associations than FEV(1) with LV mass. Among men, LV mass was positively associated with FEV(1) among current and never smokers, and with FVC among never smokers. Additional analyses among never smokers revealed significant inverse associations between LV mass and FVC among women with waist-to-hip ratios of >0.85 and those with no history of diabetes. In contrast, significant positive associations between LV mass and FVC were seen among male never smokers with body mass index (BMI) of ≤24.9 kg/m(2) , waist-to-hip ratios of ≤0.95, no history of hypertension or diabetes, and ≤60 years old. BMI and waist-to-hip ratio significantly modified associations among men. CONCLUSIONS: Among never smokers, LV mass and pulmonary function were inversely associated among women and positively associated among men. Further studies are warranted.

The Relationship between Resistance Training Frequency and Muscle Quality in Adolescents.

Previous research has established the role of resistance training (RT) on muscle function in adolescents, but a lack of evidence to optimize RT for enhancing muscle quality (MQ) exists. This study examined whether RT frequency is associated with MQ in a nationally representative adolescent cohort. A total of 605 adolescents (12−15 year) in NHANES were stratified based on RT frequency. MQ was calculated as combined handgrip strength divided by arm lean mass (via dual-energy X-ray absorptiometry). Analysis of covariance was adjusted for sex, race/ethnicity, and arm fat percentage; p < 0.05 was considered significant. RT frequency was associated with MQ for 2−7 day/week but not 1 day/week. When no RT was compared to 1−2 and 3−7 day/week, associations were present for 3−7 day/week but not 1−2 day/week. When comparing no RT to 1−4 and 5−7 day/week, associations existed for 5−7 day/week but not 1−4 day/week. Next, no RT was compared to 1, 2−3, and 4−7 day/week; associations were found for 4−7 day/week, while 2−3 day/week had a borderline association (p = 0.06); there were no associations for 1 day/week. Finally, no RT was compared to 1, 2, 3, 4, and 5−7 day/week; associations were present for all except 1 and 3 day/week. These prospective data suggest a minimum RT frequency of 2 day/week is associated with MQ in adolescents as indicated by the lack of differences in MQ between 1 day/week RT versus no RT.

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 or receiving counseling from a mental health professional in the past 12 months. We calculated age-adjusted prevalence estimates and employed t-tests to compare MHT in 2019 and 2020 using SAS-callable SUDAAN 11.0. The prevalence of MHT significantly increased from 16.3% in 2019 to 17.6% in 2020 (difference = 1.3, p = 0.030). The prevalence of taking prescription medications for mental health issues significantly increased in 2020 compared to 2019 (12.5% to 13.6%, difference = 1.1, p = 0.037). The prevalence of receiving counseling significantly increased but only among those who worked 30-49 h/week, difference = 1.2, p = 0.022. US workers, especially those with typical work hours, appeared to experience higher mental distress during the first year of the pandemic compared to the year prior to the pandemic period. These findings highlight the need for targeted interventions to address mental health issues in these workers.

Association Between the Metabolic Syndrome and Retinal Microvascular Diameters Among Police Officers.

OBJECTIVES: We examined the associations of the metabolic syndrome severity score (MSSS) and the metabolic syndrome (MetSyn) components with central retinal arteriolar equivalent (CRAE) and central retinal venular equivalent (CRVE). METHODS: Participants in this cross-sectional study were 253 officers from the Buffalo Cardio-Metabolic Occupational Police Stress study (2011-2014). The MSSS is a z -score that represents the severity of MetSyn and was estimated using a sex/race-specific equation and the five MetSyn components. Associations of MSSS and the MetSyn with CRAE/CRVE were obtained using linear regression models or analysis of covariance. RESULTS: For every 1-standard deviation of MSSS, CRAE decreased by 2.3 µm (SE = 1.2, P = 0.0262) and CRVE increased by 3.4 µm (SE = 1.6, P = 0.0308) after adjusting for confounders. CONCLUSIONS: Officers with higher MSSS had narrower (ie, worse) arteriolar diameters and wider (ie, worse) venular diameters.

Prevalence of Self-Reported Prescription Opioid Use and Illicit Drug Use Among U.S. Adults: NHANES 2005-2016.

OBJECTIVE: To estimate the self-reported prevalence of prescription opioid use and illicit drug use in the United States. METHODS: Self-reported prescription opioid use and illicit drug use (mostly nonopioid) were obtained for adults and adult workers (NHANES 2005-2016). RESULTS: Prevalence (95% CI) of prescription opioid use was 6.5% (6.0-7.0) (adults) and 4.1% (3.7-4.5) (workers). Prevalence of illicit drug use was 9.5% (8.8-10.1) (adults) and 10.2% (9.4-11.1) (workers). Among occupations, prevalence of prescription opioid use was highest in personal care (6.5%; 4.1-10.4) and healthcare practitioners (5.9%; 3.8-9.0); for illicit drug use, construction/extraction (18.0%; 15.1-21.3) and food preparation (15.8%; 12.5-19.7). CONCLUSION: The prevalence of prescription opioid use was elevated among some occupations. Judicious prescription strategies and targeted interventions are both needed. The prevalence of illicit drug use among certain occupational groups suggests the need to ensure access to therapy.

Cancer incidence among police officers in a U.S. northeast region: 1976-2006.

Police officers are exposed to occupational hazards which may put them at increased risk of cancer We examined the incidence of cancer in a cohort of 2234 white-male police officers in Buffalo, New York. The study population was followed for 31 years (1976-2006). The incidence of cancer, ascertained using a population-based tumor registry, was compared with 9 US regions using the Surveillance Epidemiology and End Results (SEER) program data. Four hundred and six officers (18.2%) developed cancer between 1976 and 2006. The risk of overall cancer among police officers was found to be similar to the general white-male population (standardized incidence ratio [SIR] = 0.94, 95%, confidence interval [CI] = 0.85-1.03). An elevated risk of Hodgkin's lymphoma was observed relative to the general population (SIR = 3.34, 95%, CI = 1.22-7.26). The risk of brain cancer, although only slightly elevated relative to the general population (SIR = 1.61, 95%, CI = 0.73-3.05), was significantly increased with 30 years or more of service (SIR = 2.92, 95%, CI = 1.07-6.36). Incidence ratios were significantly lower than expected for skin and bladder cancer Police officers were at increased risk of Hodgkin's lymphoma overall and of brain cancer after 30 years of service.

Association of sleep quality with depression in police officers.

Poor sleep quality has been shown to adversely affect neurobehavior including an increase in depression symptoms. Police officers are at increased risk of poor sleep quality due to occupational factors. This study analyzed self-reported sleep and depression data from police officers; 391 police officers from Buffalo, New York reported on sleep and depression by completing the Pittsburgh Sleep Quality Index (PSQI) and the Center for Epidemiological Studies Depression (CES-D) questionnaires. Mean CES-D scores were assessed across quintiles of PSQI. As PSQI scores increased, reflecting poorer sleep quality, CES-D scores also increased significantly indicating an increase in depression symptoms as sleep quality worsens. This trend held for both male and female officers. Mean CES-D scores across quintiles ranged from 4.72 to 12.65 in men and from 5.53 to 12.63 in women. Multivariate adjustment only very slightly attenuated the association in female officers. After adjustmnent, five of the seven PSQI components showed statistically significant associations with CES-D scores in male officers and two in female officers. Sleep quality was significantly and independently associated with depressive symnptoms as evidenced by a trend of increasing depressive symptom scores with decreasing sleep quality in both male and female officers.

Temporal trends in prevalence of cardiovascular disease (CVD) and CVD risk factors among U.S. older workers: NHIS 2004-2018.

PURPOSE: This study examined trends in the prevalence of cardiovascular disease (CVD) and CVD risk factors among U.S. older adults and workers. We also investigated correlations between the temporal prevalence of CVD and selected risk factors (hypertension, obesity, physical inactivity, smoking, and treated diabetes) among participants. METHODS: Data were obtained from the National Health Interview Survey (2004-2018) for U.S. adults aged greater than or equal to 50 years (n = 207,539), of which 84,180 were employed. Temporal trends in prevalence were assessed by fitting weighted regression models to the age-standardized prevalence to the 2010 U.S. POPULATION: The relationship between temporal prevalence of CVD with each risk factor was assessed using Spearman's correlation coefficient. RESULTS: Among all older adults, the prevalence of CVD significantly declined (ß = -0.16, P < .001) during 2004-2018; similar decline was observed among employed adults (ß = -0.16, P = .001). Temporal prevalence in CVD was positively correlated to physical inactivity (r = 0.73, P = .002) and smoking (r = 0.81, P < .001), but not to any of the other risk factors. CONCLUSIONS: Among employed adults aged greater than or equal to 50 years, the prevalence of CVD, physical inactivity, and smoking dramatically declined over the past 15 years. The temporal decline in prevalence of CVD was significantly associated with decline prevalence of physical inactivity and smoking.
