A population-based study of tractor-related injuries: Regional rural injury study - II (RRIS-II).

APHA 131st Annual Meeting and Exposition, San Francisco, California, November 15-19, 2003. Washington, DC: American Public Health Association, 2003 Nov; :73362
This study utilized data from the Regional Rural Injury Study - II (RRIS-II), a population based study, to determine the occurrence of and potential risk factors for tractor-related injuries among agricultural households with children in a five-state region of the U.S. From a random sample of 16,000 agricultural households, a cohort of 16,538 persons was followed through 1999. Demographic, exposure, and injury data were collected using a computer assisted telephone interview. Personal risk and injury event rates were calculated using generalized linear models, adjusted for within-household correlation, non-response, and unknown eligibility. Odds ratios and confidence intervals were calculated using logistic regression; selection of confounders was based on a directed acyclic graph. The annualized tractor-related injury rate was 9.6 events per 1,000 persons. In addition to agricultural machinery (E919; 35%), associated ICD-9 E-Codes included: overexertion and strenuous movements (E927; 33%), falls (E880-8; 13%), and caught in or between objects (E918; 7%). Although only 22% of injury cases were hospitalized, 26% of injuries resulted in a week or more of restricted activity; 16% resulted in a week or more of lost agricultural work time. In comparison with participants 35-44 years of age, decreased risks (ORs; 95% CIs) were identified for ages 0-4 (0.1; 0.04, 0.5), 5-9 (0.1; 0.02, 0.2), 10-14 (0.1; 0.05, 0.3), 15-19 (0.2; 0.1, 0.3), and 20-24 (0.3; 0.1, 0.9). Increased risks were observed for males compared with females (7.2; 4.3, 12.3) and prior versus no prior agricultural injury (2.0; 1.4, 2.9).
