Incidence, patterns and associated factors for occupational injuries among agricultural workers in a developing country

Background: Injuries are common among agricultural workers, and a large section of the population is employed in agriculture worldwide. We aimed to determine the incidence, patterns and associated risk factors of occupational injuries among the agricultural workers in a developing country. Methods: A cross-sectional study in Hyderabad, Pakistan was conducted from December 2012 to February 2013. Information was collected about incidence, pattern and associated risk factors of occupational injuries from 472 agricultural workers. Injury incidence and patterns for place, severity, type, agent, parts of body affected and work activity were calculated. Analysis was performed using SPSS version 19.0. Multivariate logistic regression was performed to calculate the adjusted odds ratio (OR) with 95% confidence interval, to identify the putative risk factors for occupational injuries. Results: Incidence of occupational injuries was 35.0 per 100 per year (95% CI: 28.9 - 42.7). Cuts (70%) and hand tools (71%) were the most common type and agent for injury, respectively. Majority of injuries occurred during harvesting (55%). Increasing age [AOR 1.03 (95% CI: 1.01 - 1.05)], income <6000PKR/month [AOR 2.27 (95% CI: 1.08 - 4.76)] and driving tractor [AOR 2.58 (95% CI: 1.25 -5.33)] increase the risk for injuries. Conclusion: There was a high burden of injuries among the agricultural workers in Pakistan. Large-scale studies are required to further characterize the risk of injuries and develop preventive strategies to protect agricultural workers.
