The purpose of this study was to determine whether there is an association between parent and child agricultural injuries among agricultural households in the Upper Midwest. RRIS-II, a population-based study, followed a cohort of 16,538 individuals from 3,765 agricultural operations with children during 1999. Computer-assisted telephone interviews were used to collect data for members of the household pertinent to demographics, injuries, and exposures. A nested case-control study re-examined exposure data for 203 children with agricultural injuries (cases) and 755 randomly selected controls. Analyses were conducted using individual and combined parental injury experiences as independent variables. Two parental injury time periods were evaluated separately and in combination: 1) prior to January 1999; 2) during 1999 prior to the cases' month of injury or randomly selected months for controls. Odds ratios (ORs) and confidence intervals (CIs) were generated with logistic regression; directed acyclic graphs were used to select confounders. While controlling for potential confounders (state; enterprise; parent's age, education, and number of hours worked on the operation; and number of children in the household), fathers' injuries prior to 1999 were associated with children's risk of injury (OR = 2.1; 95% CI= 1.5, 3.0), as were mothers' injuries prior to 1999 (OR = 2.5; CI = 1.7, 3.7). Mothers' injuries during 1999 were suggestive of children's risk (OR = 1.9; CI = 0.9, 4.0). Children whose parents both reported agricultural injuries prior to 1999 had more than four times the risk (OR = 4.2; CI = 2.6, 6.7) than those with neither parent injured.
