"OBJECTIVES: The objectives of this study were (i) to examine work scheduling in construction and (ii) to establish whether there is any connection between workhours and safety outcomes among construction workers. METHODS: The National Longitudinal Survey of Youth, 1979 cohort (NLSY79), was used for the data analysis. Odds ratios were used to measure the risk of work-related injury in different worker groups. RESULTS: The findings showed that (i) construction workers started work earlier, worked longer days and fewer weeks a year, and were more likely to hold multiple jobs and change jobs than their nonconstruction counterparts and (ii) long workhours and irregular work schedules were significantly associated with a higher work-related injury rate after control for possible confounders. CONCLUSION: The results provide evidence that overtime and irregular work scheduling have an adverse effect on worker safety."

"Background:Many factors contribute to occupational injuries. However, these factors have been compartmentalized and isolated in most studies.Objective:To examine the relationship between work-related injuries and multiple occupational and non-occupational factors among construction workers in the USA.Methods:Data from the 1988–2000 National Longitudinal Survey of Youth, 1979 cohort (N?=?12,686) were analyzed. Job exposures and health behaviors were examined and used as independent variables in four multivariate logistic regression models to identify associations with occupational injuries.Results:After controlling for demographic variables, occupational injuries were 18% (95% CI: 1.04–1.34) more likely in construction than in non-construction. Blue-collar occupations, job physical efforts, multiple jobs, and long working hours accounted for the escalated risk in construction. Smoking, obesity/overweight, and cocaine use significantly increased the risk of work-related injury when demographics and occupational factors were held constant.Conclusions:Workplace injuries are better explained by simultaneously examining occupational and non-occupational characteristics."

"Background. Although a large number of Hispanic workers have entered the construction industry, few studies have estimated non-fatal work-related injuries for Hispanic construction workers at a national level. This study examines work-related injury conditions among Hispanic construction workers and assesses disparities between Hispanic and white, non-Hispanic workers.
Methods. Pooled data were analyzed from a large national population survey, the Medical Expenditure Panel Survey (MEPS), between 1996 and 2002. More than 7,000 construction workers were identified from the MEPS data including 1,833 Hispanic workers and 4,533 white, non-Hispanic workers. Univariate and multivariate analyses were conducted using SAS-callable SUDAAN.
Results. Hispanic workers differ from white, non-Hispanic workers in demographic and socioeconomic status. After controlling for major risk factors, Hispanic construction workers were more likely than their white, non-Hispanic counterparts to suffer non-fatal work-related injury conditions (OR = 1.28, 95% CI: 1.00-1.64).
Conclusions. This study provides important evidence concerning Hispanic workers' safety on construction sites. Enhanced safety and health programs for Hispanic construction workers and improved occupational injury data systems are recommended."
