Construction workers continue to experience high rates of injury and illness compared with many other industries. Growing evidence suggests that safety culture has a direct effect on safety performance. This study investigated measures of safety culture and risk perception among a residential-home-building cohort within the HomeSafe Pilot Program in the Denver metro area of Colorado. Investigators compared group-level responses of management to frontline construction workers. Results indicate that managers appraised the overall safety culture at higher levels compared with the workers. Managers also perceived a higher level of management commitment to safety and health than that reported by workers.

Between 65% and 91% of human-patient sonographers report musculoskeletal symptoms related to their work activities. Ergonomic risk factors associated with musculoskeletal symptoms and musculoskeletal disorders (MSDs) include force, repetition, and awkward postures of the upper extremities. We hypothesized that veterinary sonographers experience similar risk factor exposures as their colleagues in human-patient sonography, and that work-related exposures may lead to similar prevalence of musculoskeletal symptoms and disorders. The Occupational Safety and Health Administration and Society of Diagnostic Medical Sonography published MSD prevention guidelines in 2003. Similar guidance for sonographers examining animal patients does not exist. This cross-sectional study was designed to evaluate the prevalence of musculoskeletal symptoms among veterinary sonographers and identify reported risk factors. A 59-item survey questionnaire was administered via email to veterinary specialists likely to perform ultrasound. Musculoskeletal pain related to performing ultrasound exams was reported by 62% of the respondents. Musculoskeletal symptoms were significantly associated with female gender (odds ratio [OR], 4.55; 95% confidence interval [CI], 2.04–10.19), age (OR, 1.06; 95% CI, 1.01, 1.10), previous work-related trauma (OR, 6.86; 95% CI, 1.71, 27.40), not consistently using a normal height chair (OR, 2.63; 95% CI, 1.19, 5.80), and 15°–45° abduction of shoulder (OR, 2.34; 95% CI, 1.11, 4.92) . It was concluded that the prevalence of musculoskeletal symptoms among veterinary sonographers was similar to that occurring in human-patient sonographers. © 2012 Veterinary Radiology & Ultrasound.

The purpose of this study was to evaluate standard measures of health behavior for association with back pain among college students using data from the standardized National College Health Assessment survey. This investigation evaluated potential risk factors among a population of students at a Colorado university. This cross-sectional study included 963 survey results that were assessed using backward selection logistic regression techniques to evaluate the associations between common college-life health behaviors and back pain occurrence within the past school year. Thirty-eight percent of college students surveyed reported having back pain within the past school year. Investigators found that univariate associations included multiple domains, but only psychosocial factors remained statistically significant in a final regression model and were associated with back pain. Feeling chronically fatigued (odds ratio, 3.89; 95% confidence interval, 1.09-13.86) and being in an emotionally abusive relationship (odds ratio, 2.78; 95% confidence interval, 1.69-4.57) were the factors most strongly associated with back pain in the final model. Psychosocial factors were identified to be associated with back pain. The prevalence of back pain among this younger population is of significant concern and warrants further investigation to identify contributing factors that may help in the development of interventions to reduce the epidemic of back pain within college students and lessen the burden upon college health providers.

Occupational low back pain (LBP) remains a leading safety and health challenge. This cross-sectional investigation measured the prevalence of LBP in residential carpenters and investigated ergonomic risk factors. Ninety-four carpenters were investigated for LBP presence and associated risk factors. Ten representative job-tasks were evaluated using the Ovako Working Posture Analysis System (OWAS) and ErgoMaster™ 2D software to measure elements of posture, stress, and risk. Job-tasks were found to differ significantly for total lumbar compression and shear at peak loading (p < .001), ranging from 2 956 to 8 606 N and 802 to 1 974 N respectively. OWAS indicated that slight risk for injury was found in 10 job-tasks while distinct risk was found in 7 of the 10 job-tasks. Seven of the 10 job-tasks exceeded the National Institute for Occupational Safety and Health (NIOSH) action limit of 3 400 N for low back loading. The point prevalence for LBP was 14% while the annual prevalence was 38%.

This study investigated the ability of the Revised NIOSH Lifting Equation (RNLE) to measure the risk of low back injury as verified by employee health outcomes. In addition, several basic risk factors and combinations of risk factors presumed related to low back disorders were explored. The RNLE was modified to allow analysis of one-handed and two-handed, asymmetric lifts. Predictive performance was not changed. Simplifying the RNLE by removing several variables did not significantly reduce the RNLE’s predictive performance. These modifications to the RNLE show promise for increasing both the usability and utility of the RNLE.

The support of good management is fundamental to the success of any safety and health program. Residential construction is a high-risk industry requiring significant commitment by management to impact day-to-day safety and health challenges. Investigators have evaluated management practices and spending trends in a cohort of 228 residential homebuilders in the Denver metro area of Colorado. Findings suggest that companies significantly increased dollars allocated to support safety and health practices between 1991 and 1999. In addition, the HomeSafe Pilot Program has positively impacted financial commitments of partner companies. Resource allocations were significantly greater for specific expense categories when comparing pre to post HomeSafe intervention. This paper presents data on the use of written safety and health programs, safety committees, and workers compensation premium cost containment certification, as well as allocations to safety incentive programs (SIP), personal protective equipment (PPE), other safety equipment (OSE), and safety training (ST).
