Factors that distinguish serious versus less severe strain and XXXX : an analysis of electric utility workers.

@entity6475 @entity5281 @entity130
BACKGROUND: Occupational sprain and @entity130 are one of the most common types of nonfatal @entity5281 and a significant source of lost workdays. This study examines factors associated with severe work-related @entity6475 to the back, shoulder, and knees. METHODS: A synthetic case-control study was performed (controls were selected from the same pool of utility workers as cases). Cases included all electric utility workers who had experienced a severe work-related @entity6475 to the back, knee, or shoulder. Primary controls were selected from all workers who had sustained a @entity130 . Secondary controls were selected from employees with a minor @entity6475 to the back, knee, or shoulder. Multivariate logistic regression models were used to estimate odds ratios and 95% confidence intervals. RESULTS: Workers 41 years and older were more likely to have experienced severe shoulder @entity6475 [Age 41-50: OR = 3.62, 95% CI: 1.71-7.65; age 51 and older: OR = 4.49, 95% CI: 1.89-10.67] and severe back @entity6475 [Age 41-50: OR = 1.70, 95% CI: 1.06-2.33; age 51 and older: OR = 1.5, 95% CI: 0.90-2.52]. Line workers and maintenance workers had an increased risk of serious @entity6475 . Gender and day of week were not significantly associated with @entity6475 . DISCUSSION: Though this study is limited by available data, future studies may benefit from this preliminary examination of occupational and demographic characteristics associated with serious @entity6475 among electric utility workers.
