Hearing Conservation for Farmers: Source Apportionment of Occupational and Environmental Factors Contributing to Hearing Loss

Those who work on farms continue to have a strikingly high prevalence of hearing loss, despite efforts to promote hearing conservation in agriculture. To develop improved hearing conservation programs, we performed a source apportionment analysis for hearing loss in a large, multiphasic health survey, the New York Farm Family Health and Hazard Survey. We used information from audiometric, otoscopic, and tympanometric examinations; detailed general health and farm exposure interviews; and a second interview that focused on additional potential determinants of hearing loss. Hearing loss on audiometry was significantly associated with increased age, male gender, education through high school or less, lifetime years of hunting with guns, lifetime years of use of a grain dryer, and a history of spraying crops during the previous year. Hearing conservation programs for farmers should thus be directed toward reduction in noise exposure, both from occupational and non-occupational sources. Additional study is needed to evaluate the association seen between crop spraying and hearing loss.

Safety awareness among New York farmers.

BACKGROUND This study was conducted to assess the health status and safety practices among year-round adult farm workers and residents and included a telephone interview survey of 1,727 persons from 552 farms. METHODS Logistic regression was used to analyze four safety questions. RESULTS Among 541 farm owner/operators significant predictors of making substitutions in the use of chemicals and major changes to equipment include younger age, more persons assisting on the farm, and higher gross sales. Having training is associated with having more than a high school education. Among all participants the perception that personal protective equipment are useful is associated with being younger, male, an owner/operator or worker, and having at least a high school education. CONCLUSIONS These findings suggest that older and less educated farmers should be targeted for health and safety programs.
