Assessing the Health and Climate Change Risk Perceptions of Small Farmers through Application of the Health Belief Model

Rachel Hale, MA

Purpose: By using a cross-sectional survey research design and the theoretical framework of the Health Belief Model, this study seeks to explore the overall health status of small farmers in Arkansas, their climate change and health beliefs, and risk perceptions. Understanding the current health status alongside beliefs and risk perceptions of climate change and health will inform future interventions to address adverse physical and emotional health outcomes and seeks to build their adaptive capacity. In addition, the survey will inquire what current agricultural practices the small farmer has implemented that may help their farm operation to adapt to climate change.

Occupational Injury Reporting by Farmworkers – 2004

Cynthia Ball, DO, MS

Purpose: There is a paucity of research dealing with the prevalence of work injuries among immigrants working in the United States, both agricultural and non-agricultural, and the proportion of those injuries that are reported to employers. Most of the available studies look at the percentage of injured employees who file for workers’ compensation. Yet many of these workers are employed by smaller businesses that are not required to provide worker’s compensation insurance. This study aims to measure the proportion of injured workers who actually report their injury to their employer. The method of enrollment will control for socioeconomic status. We hypothesize that immigrants who are not U.S. citizens are less likely to report injuries than U.S. citizens. U.S. citizen includes naturalized and native-born persons. The study population includes parents of migrant and traditional Head Start programs in Louisiana and West Texas. A simple occupational injury history tool has been designed and translated into Spanish.

HEP teachers will participate in training sessions to learn innovative methods to teach occupational safety and health. The curriculum will be pilot tested with HEP students enrolled in the fall and spring of the 2004 school year. Student pre-post test time series and post course evaluations will be used to measure retention, applicability of course content. Teachers will provide feedback on ease of integrating material into overall coursework, challenges and successes and willingness to permanently incorporate materials into HEP.

Establishing Exposure Risk for Noise and Organic Solvents Among Farmers – 2004

Annette Hurley, MS, CCC-A

Purpose: It is estimated that nearly 20 million workers in the U.S. are exposed to hazardous levels of noise in the workplace. Further evidence has shown that as many as 30 million American workers may be exposed to hazardous noise and ototoxic chemicals. To date, no published studies have reported hearing loss among agricultural workers as it relates to the type and extent of concomitant pesticide exposure. This feasibility study seeks to assess the risk from both noise and organic solvent exposure from which a risk assessment tool can be developed. This tool will be used to establish methods of data collection for both noise dosimetry and organic solvent exposure in order to pursue future funding to evaluate the two exposures and their effect on threshold shifts.

What is the utility of the currently available syndromic surveillance equipment and procedures in agricultural situations? What is the willingness of the agricultural community to support surveillance for diseases other than those mandated by health officials? What are the current methods of data analysis and the utility of the user feedback to the health of agricultural workers? What are the implications for joint human/animal disease surveillance?
