This study presents the results of analyses performed to generate hypotheses concerning the general patterns of risk factors for occupational sprains and strains, using Ontario workers'compensation data housed in the Workplace Health and Safety Agency (WHSA) data base.
Historically, the largest percentage of lost-time injuries in Ontario, Canada, have been sprains and strains.
In 1990, there were 171,047 compensated lost-time injuries with a known nature of injury, of which 50.43% were sprains and strains.
From cross-tabulations, a number of statistics such as odds ratios (ORsj, 95% confidence intervals, P values, attributable risks and number of injuries attributable, were calculated.
Results indicate that occupational sprains and strains are related to the time of the day and, in particular, time into the workshift.
They occur more frequently than expected (based on the occurrence of non-sprain and non-strain injuries) in the morning hours and in the first 4 hours of the workshift.
They are not found to be related to the starting or ending time or the length of the workshift.
They occur more frequently than expected during the early part of a week, especially on Mondays, and the early part of a year (January to May).
With respect to age, workers 30 to 59 years old have an increased risk of sprains and strains, whereas workers less than 30 years of age, or 60 or more years of age, have a decreased risk.
Workers who are not single, and female workers, have...
