Children/youths, as well as adults, are at risk of injury on agricultural operations where occupational and residential environments overlap. This study was conducted to determine the short- and long-term physical, psychosocial, and economic consequences of injuries occurring among children/youths living in households with agricultural operations in Minnesota, Wisconsin, North Dakota, South Dakota, and Nebraska Midwestern states characteristic of major types of agricultural production in the United States (US). From a random selection of 32,000 agricultural operations, generated from the states' operations by the US Department of Agriculture, 1,474 of 3,443 eligible households with children participated. Baseline and follow-up data on physical and mental health, agricultural and other injury disability, and economic status, were collected by trained interviewers using computerized assisted telephone interview (CATI) data collection instruments; two six-month injury data collection periods followed baseline collection. Among all household members, a total of 584 injuries were incurred with 250 related to their own agricultural operation. Respective child/youth case and control households, identified for these two six-month periods were: 1) 100 cases (122 Injuries), 366 controls; 2) 115 cases (138 injuries), 414 controls. Follow-up evaluation data were collected annually for each set, for the subsequent two years. Analyses focus on short-/long-term consequences, by examining changes between baseline, and follow-up data, comparing case and control households. Confounders are selected for multiple logistic regression analyses using directed acyclic graphs; reweighting adjusts for response and eligibility biases. This effort addresses a serious deficiency in knowledge about the burden of agricultural and other injury consequences.
