Risk factors associated with farm injuries in Canada, 1991 to 2001 : Facteurs de risque associés aux blessures à ferme au Canada

This analysis will examine the relationship between the probability of suffering an agricultural injury and the characteristics of the farm and its operator. [...] The logistic regression model will serve to investigate the relationship between the risk of injury and the independent variables selected (i.e., characteristics of the farm and its operator). [...] The coordinate at the origin α and the coefficients β associated with each of the independent variables are the elements of the logistic regression to be estimated; Xik represents the independent variable k associated with operator i of the sample; and εi is the random residual associated with operator i. The relative probability that operator i will suffer an injury can be calculated by exponenti [...] Independent variables The choice of independent variables used in the regression is based on a review of the literature, the availability of data and an analysis of correlation between the variables selected (see table of Pearson coefficients, appended). [...] Since the duration of off- farm work is inversely proportional to the time of exposure to farm work, it is likely this variable will be negatively associated with the probability of injury in the performance of farm tasks.
