Cigarette smoking in building trades workers: The impact of work environment†

BACKGROUND Blue-collar workers smoke at higher rates than white-collar workers and the general population. Occupational factors may contribute to smoking behavior in this group. However, little is known about the role of occupational factors in explaining cigarette-smoking patterns. METHODS This study used cross-sectional data from the MassBUILT smoking cessation intervention study. Multivariable logistic regression analysis was conducted to investigate the association of occupational factors with current cigarette smoking among 1,817 building trades workers. RESULTS Current cigarette smoking was significantly associated with the following occupational factors: union commitment (OR = 1.06; 95% CI: 1.00-1.12); exposure to dust (OR = 1.50; 95% CI: 1.15-1.95), exposure to chemicals (OR = 1.41; 95% CI: 1.11-1.79); and concern about exposure to occupational hazards (OR = 0.93; 95% CI: 0.91-0.95). CONCLUSION The findings highlight the need to explicate the pathways by which occupational factors may contribute to current smoking behavior among building trades workers. Smoking cessation programs for this population should consider work-related occupational factors along with individual approaches.

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.

Occupational factors associated with obesity and leisure-time physical activity among nurses: A cross sectional study

BACKGROUND AND OBJECTIVE Adverse working conditions contribute to obesity and physical inactivity. The purpose of this study was to examine the associations of occupational factors with obesity and leisure-time physical activity among nurses. METHODS This study used cross-sectional data of 394 nurses (mean age 48 years, 91% females, 61% white) randomly selected from the California Board of Registered Nursing list. Data on demographic and employment characteristics, musculoskeletal symptom comorbidity, physical and psychosocial occupational factors, body mass index (BMI), and physical activity were collected using postal and on-line surveys from January to July in 2013. RESULTS Of the participants, 31% were overweight and 18% were obese; 41% engaged in regular aerobic physical activity (≥ 150 min/week) and 57% performed regular muscle-strengthening activity (≥ 2 days/week). In multivariable logistic regression models, overweight/obesity (BMI ≥ 25 kg/m(2)) was significantly more common among nurse managers/supervisors (OR=2.54, 95% CI: 1.16-5.59) and nurses who worked full-time (OR=2.18, 95% CI: 1.29-3.70) or worked ≥ 40 h per week (OR=2.53, 95% CI: 1.58-4.05). Regular aerobic physical activity was significantly associated with high job demand (OR=1.63, 95% CI: 1.06-2.51). Nurses with passive jobs (low job demand combined with low job control) were significantly less likely to perform aerobic physical activity (OR=0.49, 95% CI: 0.26-0.93). Regular muscle-strengthening physical activity was significantly less common among nurses working on non-day shifts (OR=0.55, 95% CI: 0.34-0.89). Physical workload was not associated with obesity and physical activity. CONCLUSIONS Our study findings suggest that occupational factors significantly contribute to obesity and physical inactivity among nurses. Occupational characteristics in the work environment should be considered in designing effective workplace health promotion programs targeting physical activity and obesity among nurses.

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

BackgroundNoise-induced hearing loss (NIHL) is a major occupational health problem that can be prevented through the use of hearing protection devices (HPDs).PurposeThe purpose of this study is to identify significant factors related to firefighters’ use of HPDs.MethodsA 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.ResultsPearson 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% (R2 = .56, adjusted R2 = .54) of the variance in firefighters’ use of HPDs (F13, 372 = 35.65, p < .001).ConclusionsFuture research should focus on incorporating these significant predictors into effective behavioral interventions designed to promote the use of HPDs in this population.

Occupational injuries, duty status, and factors associated with injuries among firefighters

The aim of this study was to assess the type of occupational injuries, duty status, and factors associated with injuries among firefighters. A total of 437 firefighters from three U.S. states participated in an Internet-based survey. Approximately 66% of firefighters experienced occupational injuries and 56% reported multiple injuries. The most commonly reported injuries were muscle strains and sprains (74%), extremity injuries (60%), back injuries (54%), and burns (28%). A significant number of firefighters reported no duty (58%) or modified duty (46%). Firefighters with more than 17 years in fire services were more likely to report injuries (odds ratio [OR] = 2.96; 95% confidence interval [CI] = 1.92-4.58) and multiple injuries (OR = 2.47; 95% CI = 1.49-4.10). Hispanics (OR = 0.34; 95% CI = 0.15-0.76) and those with stronger organizational commitments (OR = 0.54; 95% CI = 0.35-0.84) were less likely to report injuries. Several factors were associated with injuries. These factors should be incorporated into interventions to reduce occupational injuries.

An Internet-Based Tailored Hearing Protection Intervention for Firefighters: Development Process and Users’ Feedback

Background. Noise-induced hearing loss is a significant occupational injury for firefighters exposed to intermittent noise on the job. It is important to educate firefighters about using hearing protection devices whenever they are exposed to loud noise. Computer technology is a relatively new health education approach and can be useful for tailoring specific aspects of behavioral change training. The purpose of this study is to present the development process of an Internet-based tailored intervention program and to assess its efficacy. Method. The intervention programs were implemented for 372 firefighters (mean age = 44 years, Caucasian = 82%, male = 95%) in three states (California, Illinois, and Indiana). The efficacy was assessed from firefighters’ feedback through an Internet-based survey. Results. A multimedia Internet-based training program was developed through (a) determining program content and writing scripts, (b) developing decision-making algorithms for tailoring, (c) graphic design and audio and video productions, (d) creating computer software and a database, and (e) postproduction quality control and pilot testing. Participant feedback regarding the training has been very positive. Participants reported that they liked completing the training via computer (83%) and also that the Internet-based training program was well organized (97%), easy to use (97%), and effective (98%) and held their interest (79%). Almost all (95%) would recommend this Internet training program to other firefighters. Conclusion. Interactive multimedia computer technology using the Internet was a feasible mode of delivery for a hearing protection intervention among firefighters. Participants’ favorable feedback strongly supports the continued utilization of this approach for designing and developing interventions to promote healthy behaviors.

Hearing loss and use of hearing protection among career firefighters in the United States

Objective: To determine the prevalence and characteristics of noise-induced hearing loss (NIHL) and the use of hearing protection devices (HPDs) among career firefighters. Methods: A Web-based survey and a standard audiometric test were performed with 425 firefighters from three states in the United States. Results: More than 40% showed hearing loss in the noise-sensitive frequencies (4 and 6 kHz). The left ear showed significantly poorer hearing than the right ear. Firefighters having longer years of work in fire services demonstrated significantly worse hearing. Reported use of HPDs was 34% of the time that was needed. Firefighters who used HPDs less were significantly more likely to have hearing loss. Conclusions: This study demonstrated a considerable NIHL problem and low use of HPDs in firefighters. More comprehensive hearing conservation programs should be implemented to reduce NIHL for firefighters.

Program Development and Effectiveness of Workplace Health Promotion Program for Preventing Metabolic Syndrome among Office Workers

This paper aims to develop and analyze the effects of a socio-ecological model-based intervention program for preventing metabolic syndrome (MetS) among office workers. The intervention program was developed using regular health examinations, a “health behavior and need” assessment survey among workers, and a focus group study. According to the type of intervention, subjects took part in three groups: health education via an intranet-based web magazine (Group 1), self-monitoring with the U-health system (Group 2), and the target population who received intensive intervention (Group 3). The intervention programs of Group 1 and Group 2, which relied on voluntary participation, did not show significant effects. In Group 3, which relied on targeted and proactive programs, showed a decrease in waist circumference and in fasting glucose (p < 0.001). The MetS score in both males (−0.61 ± 3.35 versus −2.32 ± 2.55, p = 0.001) and females (−3.99 ± 2.05 versus −5.50 ± 2.19, p = 0.028) also showed a statistically significant decrease. In light of the effectiveness of the intensive intervention strategy for metabolic syndrome prevention among workers used in this study, companies should establish targeted and proactive health care programs rather than providing a healthcare system that is dependent on an individual’s voluntary participation.

Occupational factors and smoking cessation among unionized building trades workers.

The purpose of this study was to estimate the contribution of occupational factors to smoking cessation among building trades workers. Longitudinal data came from the MassBUILT smoking cessation intervention study for unionized building trades workers. Multivariable logistic regression analyses were applied to identify the significant predictors of smoking cessation, which was defined as abstinence from smoking during the previous 7 days at the 1-month monitoring and prolonged abstinence for at least 6 months at the 6-month monitoring. Greater concern about exposure to occupational hazards was significantly associated with increased likelihood of smoking cessation at 1 month (odds ratio = 1.06; 95% confidence interval = 1.01-1.11). Additionally, smokers who had a more positive view of their unions had at least marginally increased likelihood of smoking cessation at 1 month. Furthermore, older age, higher levels of educational attainment and household income, and fewer cigarettes smoked per day were important covariates that predicted smoking cessation. Concerns about exposures to work hazards should be incorporated into comprehensive intervention approaches for building trades workers. Additionally, the findings emphasize that blue-collar workers with lower income and education levels and heavy smokers should be considered target groups for implementing cessation interventions.

Factors associated with metabolic syndrome among Korean office workers

ABSTRACT To assess the prevalence of metabolic syndrome (MetS) and identify risk factors associated with MetS among Korean office workers, this cross-sectional study was conducted with 776 office workers. The prevalence of MetS was 13.5%; elevated waist circumference (27.5%), elevated fasting glucose (23.1%), elevated triglycerides (22.2%), low high-density lipoprotein cholesterol (HDL-C) (13.4%), and elevated BP (9.4%). Having any medical health problems (OR = 3.98, 95% CI: 2.01–7.85), more knowledge of MetS (OR = 1.26, 95% CI: 1.02–1.56), higher BMI (OR = 1.42, 95% CI: 1.30–1.57), current smoking (OR = 3.78, 95% CI: 1.04–13.73), and physical inactivity (OR = 3.22, 95% CI: 1.21–8.58) were significantly associated with increased likelihood of MetS. Addressing the influence of these factors on MetS could lead to the development of workplace-based intervention strategies to encourage lifestyle changes and prevent the risk of MetS among Korean office workers.
