The purpose of this case–control study nested in the Agricultural Health Study was to assess risk factors for agricultural injury among a large group of Iowa farmers. A questionnaire sent to 6,999 farmers identified 431 cases who had a farm work–related injury requiring medical advice/treatment in the previous year and 473 controls who had no injury in the previous year. We assessed several potential risk factors for injury. A multiple logistic regression analysis showed significant associations between farm work–related injury and weekly farming work hours (> 50 hours/week) (OR = 1.65; 95% CI = 1.23–2.21), the presence of large livestock (OR = 1.77; 95% CI = 1.24– 2.51), education beyond high school (OR = 1.61; 95% CI = 1.21–2.12), regular medication use (OR = 1.44; 95% CI = 1.04–1.96), wearing a hearing aid (OR = 2.36; 95% CI = 1.07–5.20), and younger age. These results confirm the importance of risk factors identified in previous analytic studies and suggest directions for future research in preventive intervention strategies to reduce farm work–related injuries.
