Prevalence rates for depression by industry: a claims database analysis.

PURPOSE: To estimate and interpret differences in depression prevalence rates among industries, using a large, group medical claims database. METHODS: Depression cases were identified by ICD-9 diagnosis code in a population of 214,413 individuals employed during 2002-2005 by employers based in western Pennsylvania. Data were provided by Highmark, Inc. (Pittsburgh and Camp Hill, PA). Rates were adjusted for age, gender, and employee share of health care costs. National industry measures of psychological distress, work stress, and physical activity at work were also compiled from other data sources. RESULTS: Rates for clinical depression in 55 industries ranged from 6.9 to 16.2 %, (population rate = 10.45 %). Industries with the highest rates tended to be those which, on the national level, require frequent or difficult interactions with the public or clients, and have high levels of stress and low levels of physical activity. CONCLUSIONS: Additional research is needed to help identify industries with relatively high rates of depression in other regions and on the national level, and to determine whether these differences are due in part to specific work stress exposures and physical inactivity at work. CLINICAL SIGNIFICANCE: Claims database analyses may provide a cost-effective way to identify priorities for depression treatment and prevention in the workplace.

Workplace psychosocial factors associated with hypertension in the U.S. workforce: a cross-sectional study based on the 2010 national health interview survey.

OBJECTIVE: To explore associations between self-reported hypertension and workplace psychosocial factors that are common among U.S. workers and to identify industries and occupations (I&Os) that are associated with a high prevalence of hypertension, even after adjustment for common known risk factors. METHODS: Data from the 2010 National Health Interview Survey were used to examine relationships between the prevalence of self-reported hypertension and job insecurity, hostile work environment, work- family imbalance, work hours and I&O. RESULTS: Job insecurity (adjusted prevalence ratio (aPR): 1.11; 95% confidence interval (CI): 1.04-1.19)) and hostile work environment (aPR: 1.15; 95% CI: 1.03-1.29) were significantly associated with hypertension. Hypertension prevalence was significantly elevated among those employed in Healthcare Support occupations and Public Administration industries. CONCLUSION: Addressing hostile work environments and the stress associated with job insecurity may improve workers' health. Other occupational factors that contribute to the variation in prevalence of hypertension by I&O should be sought.

Workplace Psychosocial Factors, Work Organization, and Physical Exertion as Risk Factors for Low Back Pain Among US Workers: Data From the 2015 National Health Interview Survey.

OBJECTIVE: To evaluate the association between workplace psychosocial, organization, and physical risk factors with low back pain (LBP) among US workers. METHODS: 2015 National Health Interview Survey data were analyzed to calculate the prevalence rates and prevalence ratios for LBP across levels of workplace psychosocial and organizational risk factors among 17,464 US adult workers who worked ≥20 hours per week. Results were also stratified by workplace physical exertion. RESULTS: The adjusted prevalence rates of LBP were significantly elevated for workers reporting high job demand, low job control, work-family imbalance, bullying, job insecurity, working alternate shifts, and physical exertion. Job control and nonstandard shifts were significantly associated with LBP only among those who reported low/no physical exertion. CONCLUSIONS: LBP prevalence was associated with select workplace psychosocial and organization risk factors. Stratification by physical exertion modified multiple associations.

Job insecurity, work-family imbalance, and hostile work environment: prevalence data from the 2010 National Health Interview Survey.

BACKGROUND: Little nationally representative information on job insecurity, work-family imbalance, and hostile work environments experienced by workers in the US is available. METHODS: Prevalence rates from the 2010 National Health Interview Survey (NHIS) were calculated for three workplace psychosocial factors (job insecurity, work-family imbalance, bullying/harassment) using SUDAAN to account for the complex NHIS sample design. RESULTS: Data were available for 17,524 adults who worked in the 12 months that preceded the interview. Overall prevalence rates were 31.7% for job insecurity, 16.3% for work-family imbalance, and 7.8% for hostile work environment (being bullied or harassed). The highest prevalence rate of job insecurity was found for construction and extraction occupations. Workers in legal occupations had the highest prevalence rate of work-family imbalance. Workers in protective service occupations had the highest prevalence rate of hostile work environment. CONCLUSIONS: We identified demographic characteristics along with industries and occupations with the highest prevalence rates for three adverse workplace psychosocial factors. These data can be used for benchmarking and identification of targets for investigation and intervention activities.

Prevalence rates of work organization characteristics among workers in the U.S.: data from the 2010 National Health Interview Survey.

BACKGROUND: Surveillance is needed to capture work organization characteristics and to identify their trends. METHODS: Data from the 2010 National Health Interview Survey (NHIS) were used to calculate prevalence rates for four work organization characteristics (long work hours, non-standard work arrangements, temporary positions, and alternative shifts) overall, and by demographic characteristics, and industry and occupation of current/recent employment. RESULTS: Data were available for 27,157 adults, of which 65% were current/recent workers. Among adults who worked in the past 12 months, 18.7% worked 48 hr or more per week, 7.2% worked 60 hr or more per week, 18.7% had non-standard work arrangements, 7.2% were in temporary positions, and 28.7% worked an alternative shift. CONCLUSIONS: Prevalence rates of work organization characteristics are provided. These national estimates can be used to help occupational health professionals and employers to identify emerging occupational safety and health risks, allow researchers to examine associations with health, and use the data for benchmarking.

Workplace assaults on nursing assistants in US nursing homes: a multilevel analysis.

OBJECTIVES: We examined risk factors for injuries to nursing assistants from assaults by nursing home residents at both the individual and the organizational level. METHODS: We analyzed data from the 2004 National Nursing Assistant Survey that were linked to facility information from the 2004 National Nursing Home Survey by use of multilevel modeling that accounted for the complex survey design effect. RESULTS: Thirty-four percent of nursing assistants surveyed reported experiencing physical injuries from residents' aggression in the previous year. Mandatory overtime (odds ratio [OR] = 1.65; 95% confidence interval [CI] = 1.22, 2.24) and not having enough time to assist residents with their activities of daily living (OR = 1.49; 95% CI = 1.25, 1.78) were strongly associated with experiencing injuries from assaults. Nursing assistants employed in nursing homes with Alzheimer care units were more likely to experience such injuries, including being bitten by residents. CONCLUSIONS: Reducing mandatory overtime and having a less demanding workload may reduce the risk of workplace violence. In particular, prevention activities should be targeted at those nursing homes that care for cognitively impaired patients.

Racial and ethnic disparities in work-related injuries and socio-economic resources among nursing assistants employed in US nursing homes.

BACKGROUND: We aimed to estimate the proportion of nursing assistants (NAs) in the US with work-related injuries and insufficient socio-economic resources by race/ethnicity. METHODS: Data from the 2004 National Nursing Assistant Survey (NNAS), a nationally representative sample survey of NAs employed in United States nursing homes, were analyzed accounting for the complex survey design. RESULTS: Among 2,880 participants, 44% reported "scratch, open wounds, or cuts" followed by "back injuries" (17%), "black eyes or other types of bruising" (16%), and "human bites" (12%). When compared to non-Hispanic white NAs, the adjusted rate ratio (RR) for wound/cut was 0.74 for non-Hispanic black NAs (95% confidence interval [CI]: 0.65-0.85). RRs for black eyes/bruises were 0.18 for non-Hispanic black NAs (95% CI: 0.12-0.26), and 0.55 for Hispanic NAs (95% CI: 0.37-0.82). CONCLUSIONS: Minority racial and ethnic groups were less likely to report having experienced injuries compared with non-Hispanic white NAs. Future research should focus on identifying preventable risk factors, such as differences by race and ethnicity in the nature of NA jobs and the extent of their engagement in assisting patients with activities of daily living.

Mortality among members of a truck driver trade association.

Previous studies report that truck drivers are at increased risk for illness and on-the-job mortality. It is unknown whether owner-operator truck drivers face the same risks as employee drivers, yet few studies have targeted owner-operators as a study population. This study examined the overall and cause-specific mortality ratios for a cohort with owner-operator truck drivers constituting 69% of the study population. Of the 26 major disease classifications and 92 specific causes of death examined, only mortality due to transportation accidents was significantly elevated (standardized mortality ratio=1.52, 95% confidence interval=1.36-1.70). Leading causes of death were ischemic heart disease and lung cancer, although risk was below that of the general population. Transportation accidents pose a particular hazard for members of the trade association. The absence of excess disease mortality deserves careful interpretation, and may be due to both a strong healthy worker effect and a short monitoring period.

Trust in the Work Environment and Cardiovascular Disease Risk: Findings from the Gallup-Sharecare Well-Being Index.

This study examined associations between trust, an important aspect of workplace social capital, with seven cardiovascular disease (CVD) risk factors (American Heart Association Life's Simple 7 (LS7)): smoking, obesity, low physical activity, poor diet, diabetes, high cholesterol, and high blood pressure. Data are from the U.S. Gallup-Sharecare Well-Being Index (2010⁻2012), a nationally representative telephone survey of U.S. workers (n = 412,884). The independent variable was the response to a work environment (WE) question as to whether their supervisor always creates an open and trusting environment. Regression models were adjusted for demographic characteristics with each of the LS7 CVD risk factors as dependent variables. Twenty-one percent of workers reported that their supervisor did not create an open and trusting environment. Trust was associated with increased adjusted odds of having many of the LS7 CVD risk factors. Among those workers whose supervisor created a mistrustful environment, the odds ratios were greatest (>20%) for having four or more of the LS7 CVD risk factors.

Availability of and Participation in Workplace Health Promotion Programs by Sociodemographic, Occupation, and Work Organization Characteristics in US Workers.

PURPOSE: To examine how the availability of and participation in workplace health promotion programs (WHPPs) vary as a function of sociodemographic, occupation, and work organization characteristics. DESIGN: Cross-sectional study. SETTING: 2015 National Health Interview Survey and Occupational Health Supplement. PARTICIPANTS: The study sample included 17 469 employed adults who completed the WHPP questions. MEASURES: The 2 dependent outcome measures were availability of WHPPs and participation in these programs when available. Independent variables included occupation and 8 work organization and employment characteristics: company size, hours worked, supervisory responsibility, hourly pay, paid sick leave, health insurance offered by employer, work schedule, and work arrangement. ANALYSIS: Poisson regression analyses were conducted with SUDAAN 11.0.1. RESULTS: Overall, 57.8% of 46.6% employees who have WHPPs available reported participating in these programs. This study found that adults who worked ≤20 h/wk, worked regular night shifts, were paid by the hour, or worked for temporary agencies were less likely to participate in WHPPs. Workers who supervised others were 13% more likely to participate than nonsupervisors. Borderline associations were seen for having access to employer-sponsored health insurance and working at a site with <10 employees. CONCLUSION: Despite the potential for improving physical and mental health, only 58% of US workers participated in WHPPs. Since barriers to WHPP participation (eg, time constraints, lack of awareness, and no perceived need) may vary across occupations and work organization characteristics, employers should tailor WHPPs based on their specific work organization characteristics to maximize participation.

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 dichotomous responses (yes or no) to five questions and deriving a composite measure of discrimination (yes to at least one). Prevalence estimates and age- and region-adjusted prevalence ratios were derived with use of SUDAAN software to account for the complex sample design. Analyses were stratified by race and sex subgroups. This sample represents over 40 million U.S. workers aged ≥48 years. The prevalence of workplace discrimination ranged from a high of 25% for black women to a low of 11% for white men. Blacks reported a 60% higher rate of discrimination compared to whites; women reported a 53% higher prevalence of discrimination, compared with men. The prevalence of workplace mistreatment ranged from 13% for black women to 8% for white men. Women reported a 52% higher prevalence of mistreatment compared to men, while differences by race were not significant. Mistreatment was 4-8 times more prevalent among those reporting discrimination than among those reporting none. Subgroup differences in mistreatment were confined to the wage-employed. Findings suggest that middle age and older wage-employed blacks and women experience the highest prevalence of WDM; moreover, discrimination is strongly associated with mistreatment. This study contributes to our understanding of at-risk segments of the U.S. labor market and the need for targeted interventions to reduce WDM.

Ethnic, racial, and gender variations in health among farm operators in the United States.

PURPOSE: The purpose of this study was to collect baseline prevalence data on the health problems faced by minority, white, and female farm operators. METHODS: An occupational health survey of farm operators was conducted by the U.S. Department of Agriculture, National Agricultural Statistics Service between February and August 2000. A stratified random sample of farm operators from 50 U.S. states based on the 1997 Census of Agriculture was selected for telephone interview. Interviews were primarily conducted using a computer assisted telephone instrument system. RESULTS: Population prevalences were calculated for 7137 farm operators. Prevalences were greatest for musculoskeletal discomfort, followed by respiratory problems, hearing loss, and hypertension. Generally, Latino and Asian American operators had lower prevalences for health problems than white non-Latino and white operators, respectively. African-American operators had greater prevalences for hypertension, and osteoarthritis, but lower prevalences for hearing loss, skin problems, heart problems, and cancer than white operators. American Indian or Alaska Native operators had higher prevalences for musculoskeletal problems, skin problems, and hypertension. CONCLUSIONS: Prevalences for the different ethnicity and race groups are not the same. Studies that combine racial and ethnic groups, or study only white and non-Latino farm operators may overestimate or underestimate the prevalence of health conditions in the entire farm operator population.

Elevated Depressive Symptoms Among Hired Crop Workers in the United States: Variation by Sociodemographic and Employment Characteristics.

We present prevalence rates, along with demographic and economic characteristics associated with elevated depressive symptoms (EDS), in a nationally representative sample of hired crop workers in the United States. We analyzed in-person interviews with 3,691 crop workers collected in 2009-2010 as part of a mental health and psychosocial supplement to the National Agricultural Workers Survey. The prevalence of EDS was 8.3% in men and 17.1% in women. For men, multivariate analysis showed that EDS was associated with years of education, family composition, having a great deal of difficulty being separated from family, having fair or poor general health, ability to read English, fear of being fired from their current farm job, and method of payment (piece, salary, or a combination). Interactions were found between region of the country and family composition. Multivariate analyses for women showed that fear of being fired, fair or poor general health, having children ≤15 years of age, being unaccompanied by their nuclear family, expectation for length of time continuing to do farm work in the United States, and authorization status were associated with EDS. Interactions were found with Hispanic ethnicity and region of the country, as well as presence of the nuclear family and region. The present study identifies important risk factors in this first population-based assessment of EDS in a nationally representative sample of U.S. crop workers. The importance of social support from family, job insecurity, and high prevalence of EDS in female crop workers support the need for screening and outreach in this primarily rural group of men and women crop workers.

Race, occupation, and lung cancer: detecting disparities with death certificate data.

OBJECTIVES: To determine whether the analysis of death certificate data would reveal the same relationship among race, occupational exposure, and lung cancer mortality observed by a large cohort study. METHODS: An occupation-specific mortality odds ratio (MOR) for lung cancer (ICD-162) versus all other causes was calculated for 218,341 black men and white men who had been employed in the metal industries. RESULTS: Black men were at increased risk for lung cancer mortality when compared with white men among the 4668 oven workers (MOR = 1.38, 95% CI = 1.10 to 1.73), but not among the 33,605 white-collar workers (MOR = 0.95, 95% CI = 0.74 to 1.23). CONCLUSIONS: Our findings corroborate a previously demonstrated association among exposure to carcinogenic coke oven emissions, race, and lung cancer mortality, and support the use of death certificate data to help identify occupations with racial disparities in lung cancer mortality.

Job Characteristics Associated With Self-Rated Fair or Poor Health Among U.S. Workers.

INTRODUCTION: Approximately 60% of the U.S. adult population is employed. Many aspects of a person's job may influence health, but it is unclear which job characteristics are most strongly associated with health at a population level. The purpose of this study was to identify important associations between job characteristics and workers' self-rated health in a nationally representative survey of U.S. workers. METHODS: Data from the 2010 National Health Interview Survey were used to calculate weighted prevalence rates for self-reported fair/poor health for five categories of job characteristics: occupation; pay/benefits (economic); work organization; chemical/environmental hazards; and psychosocial factors. Backward elimination methods were used to build a regression model for self-reported health with the significant job characteristics, adjusting for sociodemographic variables and health behaviors. Data were collected in 2010 and analyzed in 2012-2016. RESULTS: After adjusting for covariates, workers were more likely to have fair/poor health if they were employed in business operations occupations (e.g., buyers, human resources workers, event planners, marketing specialists; adjusted prevalence ratio [APR]=1.85, 95% CI=1.19, 2.88); had no paid sick leave (APR=1.35, 95% CI=1.11, 1.63); worried about becoming unemployed (APR=1.43, 95% CI=1.22, 1.69); had difficulty combining work and family (APR=1.23, 95% CI=1.01, 1.49); or had been bullied/threatened on the job (APR=1.82, 95% CI=1.44, 2.29). CONCLUSIONS: Occupation, lack of paid sick leave, and multiple psychosocial factors were associated with fair/poor health among U.S. workers at the population level in 2010. Public health professionals and employers should consider these factors when developing interventions to improve worker health.

Evaluating Job Demands and Control Measures for Use in Farm Worker Health Surveillance.

Workplace stress likely plays a role in health disparities; however, applying standard measures to studies of immigrants requires thoughtful consideration. The goal of this study was to determine the appropriateness of two measures of occupational stressors ('decision latitude' and 'job demands') for use with mostly immigrant Latino farm workers. Cross-sectional data from a pilot module containing a four-item measure of decision latitude and a two-item measure of job demands were obtained from a subsample (N = 409) of farm workers participating in the National Agricultural Workers Survey. Responses to items for both constructs were clustered toward the low end of the structured response-set. Percentages of responses of 'very often' and 'always' for each of the items were examined by educational attainment, birth country, dominant language spoken, task, and crop. Cronbach's α, when stratified by subgroups of workers, for the decision latitude items were (0.65-0.90), but were less robust for the job demands items (0.25-0.72). The four-item decision latitude scale can be applied to occupational stress research with immigrant farm workers, and potentially other immigrant Latino worker groups. The short job demands scale requires further investigation and evaluation before suggesting widespread use.

Prevalence of musculoskeletal symptoms among agricultural workers in the United States: an analysis of the National Health Interview Survey, 2004-2008.

Ergonomic risks from agricultural tasks can compromise musculoskeletal health of workers. This study estimated prevalence of musculoskeletal symptoms in a sample representing almost 2 million US agricultural industry workers. This study used National Health Interview Survey data from 2004 to 2008. Weighted prevalence was calculated by demographic and employment factors. Prevalence ratios were calculated using generalized linear models with the Poisson distribution assumption. Prevalence rates of low back and neck pain in the previous 3 months were 24.3% and 10.5%, respectively, among agricultural workers. Monthly prevalence of joint pain was 17.0% for hips/knees, 9.8% for shoulders, 9.5% for wrists/hands, 5.4% for elbows, and 4.7% for ankles/toes. Agricultural workers had a significantly higher prevalence of shoulder pain than all other industry workers (prevalence ratios [PR] = 1.28, 95% confidence interval [CI]: 1.02-1.61). This study provides detailed national estimates of musculoskeletal symptom prevalence to understand the burden and the need for intervention among agricultural workers.

Job control, psychological demand, and farmworker health: evidence from the national agricultural workers survey.

OBJECTIVE: Improve understanding of the potential occupational health impact of how agricultural jobs are organized. Exposure to low job control, high psychological demands, and high job strain were hypothesized to have greater risk for poor self-rated physical health and elevated depressive symptoms. METHODS: Cross-sectional data (N = 3691) obtained using the Work Organization and Psychosocial Factors module of the US National Agricultural Workers Survey fielded in 2009-2010. RESULTS: More than one fifth (22.4%) of farmworkers reported fair/poor health, and 8.7% reported elevated depressive symptoms. High psychological demand was associated with increased risk of fair/poor health (odds ratio, 1.73; 95% confidence interval, 1.4 to 2.2) and elevated depressive symptoms (odds ratio, 2.6; 95% confidence interval, 1.9 to 3.8). CONCLUSIONS: The organization of work in field agriculture may pose risks for poor occupational health outcomes among a vulnerable worker population.

Excess risk of head and chest colds among teachers and other school workers.

BACKGROUND: Work-related injuries and illnesses in the educational services sector have not been well studied. This analysis examined whether teachers and other school workers are at higher risk of head/chest cold compared to all other workers in the United States. METHODS: Seven years (1998-2004) of National Health Interview Survey data on currently employed workers were combined to provide a basis for estimating the incidence proportion of head/chest cold. RESULTS: The adjusted odds ratio for head/chest cold was significantly elevated for teachers and other workers employed at schools compared to all other workers. When examined by month, an excess of increased head/chest cold risk during the school year suggested that a portion of head/chest cold among teachers and other school workers is attributable to their workplace, perhaps due to close contact with students at school. CONCLUSION: Head/chest cold, a surrogate for acute respiratory infection, was more common among school workers during the school year and less common during July than for all other workers in the United States. Targeted training for school workers and students may be beneficial to reduce work-related exposure to viruses and bacteria that infect the respiratory system.
