Exploring the characteristics and health outcomes of working from home: Analysis of 2021 California Health Interview Survey data.

BACKGROUND: Working from home (WFH) may affect health behaviors and mental health. The coronavirus disease-2019 (COVID-19) pandemic saw many US employees transition to WFH, which has persisted in various job sectors and significantly impacted employees. However, its effects on health outcomes have remained unclear. We aimed to explore the characteristics and health outcomes of, and health-related differences between, WFH and not-WFH groups. METHODS: Using the 2021 California Health Interview Survey data, we analyzed health behaviors (smoking, alcohol consumption, and fruit-related nutrition) and the mental health status of 12,438 individuals using descriptive statistics, Pearson's χ2 test, and regressions. RESULTS: A total of 39% were WFH and 61% were not-WFH. Overall, the WFH group had worse health behaviors and mental health than the not-WFH group. Age was associated with smoking in both groups (WFH: b = 0.37; not-WFH: b = 0.35), but with fruit-related nutrition only in the WFH group. Household income and occupation were associated with alcohol consumption in both groups. Age (WFH: b = -1.58; not-WFH: b = -1.39), household income (WFH: b = -0.75; not-WFH: b = -0.34), and job duration (WFH: b = -0.34; not-WFH: b = -0.40) were associated with mental health in both groups; those who were younger and had lower household incomes and job durations had worse mental health. CONCLUSION: Health management is a clear necessity for the WFH group. Irrespective of WFH status, young workers with shorter than 5 years' job duration reported mental distress, highlighting a need for distress assessment and management for the young workforce.

Underreporting of workers' injuries or illnesses and contributing factors: a systematic review.

BACKGROUND: Accurate identification of work-related health problems is important to understand workplace safety issues and develop appropriate interventions. Although workers' reporting of work-related injuries or illnesses is the very first step of the reporting process, many workers may encounter challenges in reporting them to their management or workers' compensation (WC) programs. This systematic review aimed to identify the level of workers' underreporting of work-related injuries and illnesses and the contributing factors and reasons for underreporting among US workers. METHODS: This study searched PubMed (Medline), PsycINFO (ProQuest), CINAHL (EBSCOhost), EMBASE (Embase.com), and Social Science Citation Index (Web of Science) using search terms related to underreporting of work-related injury or illness. RESULTS: Twenty studies (17 quantitative and three mixed methods studies) were identified. The studies investigated reporting to management (n = 12), WC programs (n = 6), multiple organizations (n = 1), and not specified (n = 1). The timeframe used to measure reporting prevalence varied from three months to entire careers of workers, with the most common timeframe of 12 months. This review indicated that 20-91% of workers did not report their injuries or illnesses to management or WC programs. From quantitative studies, contributing factors for injury or illness underreporting were categorized as follows: injury type and severity, sociodemographic factors (e.g., age, gender, education, and race/ethnicity), general health and functioning, worker's knowledge on reporting, job and employment characteristics (e.g., work hour, job tenure, work shift, type of occupation, and physical demand), psychosocial work environment (e.g., supervisor support, coworker support, and safety climate), and health care provider factors. From the review of qualitative studies, the reasons for underreporting included the following: fear or concern, cumbersome time and effort in the reporting process, lack of knowledge regarding reporting, perceptions of injuries as not severe or part of the job, and distrust of reporting consequences. CONCLUSIONS: The review findings indicated that low wage earners, racial/ethnic minority workers, and workers who perceive a poor psychosocial work environment encounter more barriers to reporting a work-related injury or illness. This review also identified variations in the measurement of work-related injury reporting across studies and a lack of standardized measurement. TRIAL REGISTRATION: The review was registered in the PROSPERO, an international database of prospectively registered systematic reviews in health and social care (CRD42021284685).

Testing the reliability and validity of the modified Amsterdam Inventory for Auditory Disability and Handicap in career firefighters in the United States.

BACKGROUND: Firefighters are routinely exposed to loud noise that put them at risk for hearing loss. A reliable and valid measure to assess firefighters' hearing function is important. This study aims to test the reliability and validity of the modified Amsterdam Inventory for Auditory Disability and Handicap ((m)AIADH) in firefighters. METHOD: A cross-sectional study was conducted using a convenience sample of 239 career firefighters from six partnered fire departments in Central Texas and Northern California. The internal consistency, convergent and criterion validity, and the ability to discriminate groups by measured hearing, perceived hearing, and a combination of measured and perceived hearing, were examined using the total score and score for each of the five subscales of the (m)AIADH. RESULTS: The study participants were primarily men (93%). Satisfactory internal consistency was revealed for the (m)AIADH with Cronbach's alpha above 0.80 for all five subscales. Criterion analysis presented a moderate correlation between the (m)AIADH and the average of hearing threshold at high frequencies (4, 6, and 8 kHz). For convergent validity, the (m)AIADH was moderately to highly related with perceived hearing. There were statistically significant differences in the total (m)AIADH score and the five subscales for measured hearing thresholds except for "intelligibility in quiet." The (m)AIADH also showed a discriminative ability to distinguish between the group with good perceived hearing and the group with bad perceived hearing. CONCLUSION: The (m)AIADH is a reliable and valid measure to assess various dimensions of hearing function among firefighters.

The effect of COVID-19 on workplace violence in California's hospitals: An interrupted time series analysis.

AIM: This study used California's unique Workplace Violent Incident Reporting System (WVIRS) to describe changes in workplace violence (WV) exposure for hospital-based healthcare workers during the pandemic. DESIGN: Interrupted time series analysis. METHODS: We compared the linear trends in weekly WV incidents reported during the period before the COVID-19 pandemic (7/1/2017-3/20/2020) to the period following California's shutdown (3/21/2020-6/30/2021). We created mixed effects models for incidents reported in emergency departments (EDs) and in other hospital units. We used hospital volume data from the California Department of Health Care Access and Information. RESULTS: A total of 418 hospitals reported 37,561 incidents during the study period. For EDs, the number of reported incidents remained essentially constant, despite a 26% drop in outpatient visits between the first and second quarters of 2020. For other hospital units, weekly incidents initially dropped-parallel to a 13% decrease in inpatient days between the first and second quarters of 2020-but then continued parallel to the trend seen in the pre-COVID period. CONCLUSION: WV persists steadily in California's hospitals. Despite major reductions in patient volume due to COVID-19, weekly reported ED incidents remained essentially unchanged. IMPACT: Surveys and media reported that WV increased during the pandemic, but it has been difficult to measure these changes using a large-scale database. The absolute number of WV incidents did not increase during the pandemic; however, the trend in reported incidents remained constant in the context of dramatic decreases in patient volume. New federal WV prevention legislation is being considered in the U.S. California's experience of implementation should be considered to improve WV reporting and prevention. PUBLIC CONTRIBUTION: There was no public contribution to this study. The goal of this analysis was to summarize findings from administrative data. The findings presented can inform future discussion of public policy and action.

The short form effort-reward imbalance: Measure of occupational stress for firefighters.

PURPOSE: The original effort-reward imbalance (ERI) questionnaire has been widely used as a measure of occupational stress. The need for brief measurement of psychosocial stress at work has risen. This study examined the psychometric properties of a 16-item short form ERI (S-ERI) questionnaire. METHODS: A cross-sectional study was conducted with a convenience sample of 247 career firefighters in the United States. An internet-based survey contained the S-ERI questionnaire, and assessed perceived health, demographics, and work characteristics. Internal consistency was tested by item-total correlation and Cronbach's α coefficients. Factorial validity was assessed by confirmatory factor analysis (CFA), and criterion validity was examined by testing the S-ERI's association with perceived health, controlling for other factors. RESULTS: The study participants were primarily young and mid-aged White males (mean age = 42 years, 75% White non-Hispanic, 93% males). The S-ERI questionnaire showed satisfactory internal consistency, with Cronbach α coefficients above 0.80 for all three scales: effort 0.82, reward 0.83, and overcommitment 0.81. CFA showed all the S-ERI components had a good fit (goodness-of-fit index = 0.99, comparative fit index = 0.92, root mean square error of approximation = 0.06). In terms of criterion validity, significantly increased odds ratios (ORs) for perceived health (those indicating they were less healthy) were found in firefighters in the lowest tertile of reward (OR = 7.06, 95% confidence interval [CI]: 2.86-17.43), and highest tertile of overcommitment (OR = 2.29, 95% CI: 1.00-5.22), after controlling for other factors. CONCLUSION: The S-ERI questionnaire is a reliable and valid measure to assess occupational stress. We recommend the use of S-ERI as a measure of occupational stress when initiating efforts to improve firefighters' wellness.

Differences in Hospitals' Workplace Violence Incident Reporting Practices: A Mixed Methods Study.

Workplace violence (WV) is a significant and growing problem for health care workers. Increased recognition of the need for improved protections has led to policy initiatives at the state and federal levels, including national Joint Commission requirements that went into effect January 2022. California's WV prevention legislation was phased in during 2017-2018 and requires hospitals to use a new incident reporting system, the Workplace Violent Incident Reporting System (WVIRS) for Hospitals. We analyzed WVIRS data collected during the first three years of its implementation, July 1, 2017 - June 30, 2020. In addition, we collected qualitative data from six California hospitals/hospital systems during 2019-2020 to better understand reporting practices. Over the three-year period, the 413 hospitals using the WVIRS reported between zero and six incidents per staffed bed. Sixteen hospitals (3.9%) reported two or more incidents per staffed bed while the rest reported fewer than two incidents. Qualitative analysis identified that reporting procedures vary considerably among hospitals. Several organizations rely on workers to complete incident reports electronically while others assign managers or security personnel to data collection. Some hospitals appear to report only those incidents involving physical harm to the worker. Regulatory guidance for reporting practices and hospitals' commitment to thorough data collection may improve consistency. As hospitals throughout the U.S. consider practice changes to comply with new WV standards, those engaged in implementation efforts should look closely at reporting practices. Greater consistency in reporting across facilities can help to build evidence for best practices and lead to safety improvements.

Controlled Drinking Behaviors Among Korean American and Korean Male Workers.

BACKGROUND: A permissive drinking culture is one reason for the high level of alcohol consumption among Korean men. Despite shared experiences of the Korean drinking culture that often encourages social drinking, Korean American and Korean male workers may differ in their drinking behavior. This study examines the predictors of controlled drinking behavior and between these two groups. OBJECTIVES: The purpose of this study was to examine and compare the predictors of controlled drinking behavior between Korean American and Korean male workers. METHODS: Two hundred eighty-two male participants (141 Korean Americans and 141 Koreans) who engaged in social drinking were surveyed. Ajzen's theory of planned behavior was used to examine the predictors of controlled drinking behavior. Structural equation modeling was employed to test the theoretical model for each group, followed by multiple-group analyses. RESULTS: Most participants were college-educated and white-collar workers. Korean American workers had fewer heavy episodic drinking days in the past month than Korean workers. Model testing for each group revealed that subjective norms and perceived behavioral control predicted intentions of controlled drinking, but only perceived behavioral control was a significant predictor of controlled drinking behavior. Multiple-group analyses indicated no difference between the two groups regarding the predictors of controlled drinking behaviors. DISCUSSION: Programs to promote controlled drinking for Korean American and Korean male workers should incorporate strategies to increase perceived behavioral control, such as training on how to decline drinking. In addition, early education for healthy drinking culture with a strict drinking environment needs to be considered to improve controlled drinking behaviors.

Gender differences in experience and reporting of acute symptoms among cleaning staff.

BACKGROUND: Cleaning tasks pose risks of hazardous chemical exposure and adverse health effects for cleaning workers. We examined gender differences among cleaning staff in the experience of chemical-related symptoms and in reporting to supervisors. METHODS: We analyzed cross-sectional reports from 171 university hospital or campus cleaning staff on chemical exposures to cleaning products, experience of acute symptoms, reporting of symptoms to supervisors, as well as demographic and psychosocial factors (risk perception, job demand/control, supervisor/co-worker support, and safety climate). Results were analized using multivariable logistic regression, adjusting for demographic, job, and psychosocial factors. Interactions of gender and psychosocial variables were also examined. RESULTS: Men and women reported different frequencies for exposure-related tasks. Acute symptoms of chemical exposure were more prevalent in women compared with men (46.0% vs. 25.4%; adjusted odds ratio [OR] = 2.63; 95% confidence interval [CI] 1.27-5.46). Women were more concerned about exposure to cleaning chemicals (p = 0.029) but reported symptoms to their supervisor less often than men (18.5% vs. 40.6%, adjusted OR = 0.28; 95% CI 0.09-0.93). More supervisor support was significantly associated with less frequent symptom experience among women (OR = 0.83; 95% CI 0.70-0.99). Asian workers and less educated workers were less likely than others to report symptoms to supervisors. Gender differences in symptom reporting to supervisors were not explained by psychosocial factors. CONCLUSIONS: Women may have increased susceptibility or perception of symptoms from cleaning compared to men, but this may be mitigated by supervisor support. Female Asian workers with lower education may perceive more significant barriers in reporting work-related symptoms to supervisors. Further research is needed to explore factors related to underreporting.

Analysis of Occupational Safety and Health Administration (OSHA) noise standard violations over 50 years: 1972 to 2019.

INTRODUCTION: Noise exposure has long been an occupational health concern and has been an important area of focus of the Occupational Safety and Health Administration (OSHA) since its founding. Nevertheless, it remains unclear what effects OSHA's noise standards have had on employer efforts to reduce risks. Consequently, a review of OSHA noise standard violations was performed to clarify the violation trends between 1972 and 2019. METHODS: Using the OSHA Information System, researchers identified 119 305 violations involving four noise standards between 1972 and 2019: 29 CFR 1910.95, occupational noise exposure in general industry; 1926.52, occupational noise exposure in construction; 1926.101, hearing protection in construction, and 1904.10, recording criteria for cases involving occupational hearing loss. Violation frequencies of noise standard subparagraphs and relationships to factors such as industry differences were analyzed using descriptive statistics and t tests. RESULTS: The most commonly violated noise standard was 1910.95 in manufacturing. Such violations rose between 1972 and 1985 and then declined steadily. Whether in general industry or construction, four noise standards were most-frequently cited: lack of feasible administrative or engineering controls (1910.95[b] and 1926.52[d]) and inadequate hearing conservation program (1910.95[c] and 1926.52[b]). These violations were more highly penalized (mean = $1036.50) than other subparagraph violations (mean = $915.80). Programmed and unprogrammed inspections generated similar violation quantities except between 1980 and 1985, when programmed inspections exhibited a sharp spike in violations. CONCLUSION: The study identified trends in OSHA noise standard violations and possible explanations for those trends. The study findings can support development of more practical noise-exposure protection policy.

Factors associated with physical injury or police involvement during incidents of workplace violence in hospitals: Findings from the first year of California's new standard.

BACKGROUND: Workplace violence in healthcare settings is known to be a costly and often underreported problem. In California, hospitals are required to report incidents of violence towards workers to the California Occupational Safety and Health Administration (CalOSHA) using an online reporting system that went into effect in 2017. METHODS: Reports submitted to CalOSHA from July 2017 to September 2018 pursuant to this new requirement were analyzed using descriptive methods and logistic regression. RESULTS: Four hundred eight hospitals submitted reports using the new incident reporting system. Behavioral health units had 1.82 times the odds of the reported incident resulting in physical injury compared to inpatient medical units, and investor-owned facilities had 2.43 times the odds of the reported incident resulting in physical injury compared to city or county-owned facilities. Inpatient and behavioral health units had significantly reduced odds of a reported incident resulting in police involvement when compared to other locations within the hospital. CONCLUSIONS: These findings indicate that protections for healthcare workers deserve ongoing attention from stakeholders and legislators and provide insight into how healthcare facilities report incidents of violence towards workers.

The Relationships of Nurse Staffing Level and Work Environment With Patient Adverse Events.

PURPOSE: The purpose of this study was to examine the relationships of nurse staffing level and work environment with patient adverse events. DESIGN: This cross-sectional study used a combination of nurse survey data (N = 4,864 nurses), facility data (N = 58 hospitals), and patient hospital discharge data (N = 113,426 patients) in South Korea. METHODS: The three most commonly nurse-reported adverse events included administration of the wrong medication or dose to a patient, pressure ulcers, and injury from a fall after admission. Multilevel ordinal logistic regression was employed to explore the relationships of nurse staffing level (number of patients assigned to a nurse) and work environment (Practice Environment Scale of the Nursing Work Index) with patient adverse events after controlling for nurse, hospital, and patient characteristics. FINDINGS: A larger number of patients per nurse was significantly associated with a greater incidence of administration of the wrong medication or dose (odds ratio [OR] = 1.01, 95% confidence interval [CI] = 1.007-1.016), pressure ulcer (OR = 1.01, 95% CI = 1.007-1.016), and patient falls with injury (OR = 1.02, 95% CI = 1.013-1.022). A better work environment had a significant inverse relationship with adverse events; the odds of reporting a higher incidence of adverse events were 45% lower for administration of the wrong medication or dose (OR = 0.55, 95% CI = 0.400-0.758), followed by 39% lower for pressure ulcer (OR = 0.61, 95% CI = 0.449-0.834) and 32% lower for falls with injury after admission (OR = 0.68, 95% CI = 0.490-0.939). CONCLUSIONS: This study found that a larger number of patients per nurse and poor work environment increase the incidence of patient adverse events, such as administration of the wrong medication or dose to a patient, pressure ulcers, and injury from falling after admission. The findings suggest that South Korean hospitals could prevent patient adverse events by improving nurse staffing and work environment. CLINICAL RELEVANCE: Healthcare strategies and efforts to modify adequate nurse staffing levels and better work environments for nurses are needed to improve patient outcomes.

Lifelong occupational exposures and hearing loss among elderly Latino Americans aged 65-75 years.

OBJECTIVE: The purpose of this study is to determine the relationship between occupational exposures and hearing among elderly Latino Americans. DESIGN: A descriptive, correlational design used for this secondary analysis with the data from the Sacramento Area Latino Study of Aging (SALSA). STUDY SAMPLE: A total of 547 older adults were included. RESULTS: A majority of participants (58%) reported occupational exposures to loud noise and/or ototoxic chemicals. About 65% and over 90% showed hearing loss at low and high frequencies, respectively. Participants with occupational exposure to loud noise and/or ototoxic chemicals were, significantly, two times more likely to have hearing loss at high frequencies compared to those without exposure (OR = 2.29; 95% CI: 1.17 = 4.51, p = .016), after controlling for other risk factors of hearing loss such as age, gender, household income, current smoking, and diabetes. However, lifelong occupational exposure was not significantly associated with hearing loss at low frequencies (OR = 1.43; 95% CI: 0.94 = 2.18, p = .094). CONCLUSION: Lifelong occupational exposure to loud noise and/or ototoxic chemicals was significantly associated with hearing loss among elderly Latino Americans. Healthy work life through protection from harmful auditory effects of occupational exposures to noise and chemicals will have a positive impact on better hearing in later life.

Acute symptoms associated with chemical exposures and safe work practices among hospital and campus cleaning workers: a pilot study.

BACKGROUND: Cleaning workers are regularly exposed to cleaning products containing hazardous chemicals. This study investigated acute symptoms associated with chemical exposures among cleaning workers and their safe work practices. METHODS: This cross-sectional study included 183 cleaning workers employed in an academic medical center and affiliated health sciences campuses in Northern California. Data on respiratory, eye, skin, neurological, and gastrointestinal symptoms and occupational factors were collected by in-person interviews or self-administered questionnaires. RESULTS: Chemical-related symptoms (several times monthly or more often) were more common among workers who performed patient area cleaning (44%) than hospital custodians (36%) or campus custodians (28%). After controlling for age, sex, and job title, symptoms were associated with exposure to carpet cleaners (OR = 2.98, 95% CI 1.28-6.92), spray products (OR = 2.82, 95% CI 1.16-6.82), solvents (OR = 2.71, 95% CI 1.20-6.15), and multi-purpose cleaners (OR = 2.58, 935% CI 1.13-6.92). Except for gloves, regular use of personal protective equipment was infrequent. CONCLUSIONS: Study findings suggest a need for additional interventions such as use of less toxic products to reduce health risks among cleaning workers.

Web-enhanced tobacco tactics with telephone support versus 1-800-QUIT-NOW telephone line intervention for operating engineers: randomized controlled trial.

BACKGROUND: Novel interventions tailored to blue collar workers are needed to reduce the disparities in smoking rates among occupational groups. OBJECTIVE: The main objective of this study was to evaluate the efficacy and usage of the Web-enhanced "Tobacco Tactics" intervention targeting operating engineers (heavy equipment operators) compared to the "1-800-QUIT-NOW" telephone line. METHODS: Operating engineers (N=145) attending one of 25 safety training sessions from 2010 through 2012 were randomized to either the Tobacco Tactics website with nurse counseling by phone and access to nicotine replacement therapy (NRT) or to the 1-800-QUIT-NOW telephone line, which provided an equal number of phone calls and NRT. The primary outcome was self-reported 7-day abstinence at 30-day and 6-month follow-up. The outcomes were compared using chi-square tests, t tests, generalized mixed models, and logistic regression models. RESULTS: The average age was 42 years and most were male (115/145, 79.3%) and white (125/145, 86.2%). Using an intent-to-treat analysis, the Tobacco Tactics website group showed significantly higher quit rates (18/67, 27%) than the 1-800-QUIT NOW group (6/78, 8%) at 30-day follow-up (P=.003), but this difference was no longer significant at 6-month follow-up. There were significantly more positive changes in harm reduction measures (quit attempts, number of cigarettes smoked per day, and nicotine dependence) at both 30-day and 6-month follow-up in the Tobacco Tactics group compared to the 1-800-QUIT-NOW group. Compared to participants in the 1-800-QUIT NOW group, significantly more of those in the Tobacco Tactics website group participated in the interventions, received phone calls and NRT, and found the intervention helpful. CONCLUSIONS: The Web-enhanced Tobacco Tactics website with telephone support showed higher efficacy and reach than the 1-800-QUIT-NOW intervention. Longer counseling sessions may be needed to improve 6-month cessation rates.

Association between Sleep Duration, Social Jetlag, and the Metabolic Syndrome by Shift Works.

Lifestyle factors, including sleep characteristics, have been implicated in the development of metabolic syndrome, particularly among shift workers. This study aimed to explore the relationship between shift work, sleep duration, social jetlag, and the risk of metabolic syndrome among U.S. workers and the moderating effect of sleep duration and social jetlag on this relationship. Data from the National Health and Nutrition Examination Survey (NHANES) in 2017-2020 March were analyzed. Poisson regression models were employed to examine associations. Among 4136 U.S. workers, 53.3% had metabolic syndrome, with a higher proportion of shift workers (63.8% vs. 56.7%, p = 0.001) and those sleeping less than 6 h or more than 9 h per week (22.3% vs. 19.1%, p = 0.044) in the affected group. Shift workers were initially found to have an increased risk of metabolic syndrome (Coef. = 0.03, 95% CI: 0.02, 0.16); however, this association was mitigated when accounting for the interaction with social jetlag. Specifically, 1 to <2 h of social jetlag interacted significantly, increasing metabolic risk (Coef. = 0.15, 95% CI: 0.09, 0.22), whereas 1 to <2 h alone showed a protective effect (Coef. = -0.11, 95% CI: -0.17, -0.06). These findings suggest that optimizing sleep schedules and addressing social jetlag may be crucial in mitigating metabolic syndrome risks among shift workers.

Factors Associated With Reporting Attitudes of Work-Related Musculoskeletal Disorders Among Direct Care Workers in South Korea.

BACKGROUND: Workers' reporting of work-related injuries or illnesses is important for treatment and prevention, yet research often focuses on reporting barriers. This study aimed to identify factors related to work-related musculoskeletal disorder (WRMSD) reporting attitudes and their connection to reporting intention and behavior. METHODS: We analyzed data from 377 direct care workers employed in 19 long-term care facilities in South Korea. A self-administered questionnaire collected demographics, job characteristics, physical and psychosocial factors, musculoskeletal symptoms, reporting attitudes, and WRMSD reporting intentions and behavior between May and August 2022. We used a generalized linear mixed model with a random intercept by employers to identify factors influencing reporting attitudes. To explore the relationship between reporting attitude and reporting intention and behavior, simple logistic regression was also conducted. RESULTS: We achieved an 86% response rate. The majority of the study participants were female (87.2%), married (95.9%), and non-immigrant (72.8%). Of the study participants, 48.9% had no intention to report WRMSDs, and 44.3% held negative reporting attitudes. Among 200 workers with WRMSDs, 86.5% did not report them. Attitudes were associated with work duration, safety training, management safety priority, WRMSD experience, and symptom severity and frequency. Management safety priority did not moderate this relationship. Significant links existed between attitudes and reporting intention and behavior. CONCLUSIONS/APPLICATIONS TO PRACTICE: This study highlights the vital influence of workers' attitudes on reporting work-related injuries and illnesses. Occupational health providers should employ strategies, such as tailored safety training and management commitment, with a focus on addressing the unique needs of long-tenured and musculoskeletal-exposed workers. Fostering a safety culture that promotes open and timely reporting is crucial, and implementing these strategies can significantly enhance workplace safety and health.

Predictors of hearing protection behavior among firefighters in the United States.

BACKGROUND: Noise-induced hearing loss (NIHL) is a major occupational health problem that can be prevented through the use of hearing protection devices (HPDs). PURPOSE: The purpose of this study is to identify significant factors related to firefighters' use of HPDs. METHODS: A total of 404 firefighters from 35 fire departments in multiple states in the United States participated in an Internet-based survey from March 2010 to May 2011. RESULTS: Pearson correlations and multiple regression analysis suggested that several modifying and cognitive-perceptual factors were significantly related to HPD use, including noise exposure, interpersonal influences, organizational support, perceived barriers to HPD use, and perceived susceptibility to hearing loss. The multiple regression model explained 56% (R(2) = .56, adjusted R(2) = .54) of the variance in firefighters' use of HPDs (F(13, 372) = 35.65, p < .001). CONCLUSIONS: Future research should focus on incorporating these significant predictors into effective behavioral interventions designed to promote the use of HPDs in this population.

The effect of a booster intervention to promote hearing protection behavior in operating engineers.

BACKGROUND: Booster interventions may be useful in promoting workers' hearing protection device (HPD) use. Previous research on the effectiveness and the optimal timeframe for boosters is limited and inconsistent. METHODS: In this randomized controlled trial, 403 workers were assigned to receive an individually tailored booster, a control booster, or no booster. The booster intervention groups were further divided by timeframe. Frequency of HPD use was measured 12 months post-intervention. RESULTS: The booster intervention groups significantly accounted for the variance in HPD use in Year 2. Workers in middle-term booster (67-94 days) group reported a significantly greater increase in HPD use in Year 2 than those in other timeframes, when potential covariates were controlled for. CONCLUSIONS: Booster intervention letters mailed between 67 and 94 days post-initial intervention may promote HPD use among participants. Future research should explore additional factors associated with optimal booster design, including more innovative mobile and internet-based approaches.

Heavy and light/moderate smoking among building trades construction workers.

OBJECTIVE: The purpose of the study was to identify the correlates of heavy smoking (defined as more than one pack of cigarettes per day) in building trades construction workers. DESIGN AND SAMPLE: This study used cross-sectional data from the MassBUILT smoking cessation intervention study at Massachusetts building trades unions with the sample of 763 smokers. MEASURES: Data collected included information about smoking behavior, individual, psychological, interpersonal, and occupational factors obtained through self-reported questionnaires. RESULTS: Approximately 21% of smokers were heavy smokers. Significant factors related to heavy smoking were: older age (OR = 1.10; 95% CI: 1.06-1.14), male gender (OR = 4.55; 95% CI: 1.62-12.79), smoking the first cigarette of the day within 30 min of waking (OR = 4.62; 95% CI: 2.81-7.59), smoking initiation at earlier age (OR = 0.93; 95% CI: 0.87-1.00), higher temptation to smoke (OR = 1.55; 95% CI: 1.17-2.05), household smoking (OR = 1.90; 95% CI: 1.18-3.06) or living alone (OR = 4.11; 95% CI: 1.70-9.92), and exposure to chemicals at work (OR = 1.61; 95% CI: 1.06-2.53). CONCLUSION: Addressing the influence of these factors on heavy smoking could lead to the development of targeted, multiple components in comprehensive cessation strategies for blue-collar smokers.
