To estimate the strength of relationships between socioeconomic status and injury in a large Canadian farm population.
We conducted a prospective cohort study of 4,769 people from 2,043 farms in Saskatchewan, Canada. Participants reported socioeconomic exposures in 2007 and were followed for the occurrence of injury through 2009 (27 months). The relative hazards of time to first injury according to baseline socioeconomic status were estimated via Cox proportional hazards models.
Risks for injury were not consistent with inverse socioeconomic gradients (adjusted HR 1.07; 95% CI: 0.76 to 1.51 for high vs low economic worry; adjusted HR 1.72; 95% CI: 1.23 to 2.42 for completed university education vs less than high school). Strong increases in the relative hazard for time to first injury were identified for longer work hours on the farm.
Socioeconomic factors have been cited as important risk factors for injury on farms. However, our findings suggest that interventions aimed at the prevention of farm injury are better focused on operational factors that increase risk, rather than economic factors per se.
在加拿大大型农场人群中评估社会经济地位与伤害之间关系的强度。
我们对加拿大萨斯喀彻温省的 2043 个农场中的 4769 人进行了一项前瞻性队列研究。参与者在 2007 年报告了社会经济暴露情况，并在 2009 年（27 个月）之前对伤害发生情况进行了随访。通过 Cox 比例风险模型估计了根据基线社会经济地位的首次伤害时间的相对风险。
受伤风险与逆社会经济梯度不一致（调整后的 HR 1.07；经济担忧程度高与低相比的 95%CI：0.76 至 1.51；完成大学教育与高中以下相比的 95%CI：1.23 至 2.42）。在农场工作时间较长时，首次伤害时间的相对危险度明显增加。
社会经济因素被认为是农场伤害的重要危险因素。然而，我们的研究结果表明，旨在预防农场伤害的干预措施应更好地侧重于增加风险的操作因素，而不是经济因素本身。
