Rationale: Reports by the U.S. government (U.S. Department of Labor ) and by private foundations (National Center for Farmworker Health , California Endowment ) highlight the health disparities, especially cancer and respiratory, experienced by migrant farm workers. While these reports cite tobacco use among migrant farm workers as a concern, the extent of tobacco use among this population is not entirely evident. It is clear, however, that the occupational health effects experienced by migrant farm workers are aggravated by tobacco use and second-hand smoke exposure. The dearth of information available may be partially explained by the difficulties in accessing and studying this relatively small population group. More specifically, there are certain characteristics associated with this population that present significant methodological challenges to conducting cross sectional and longitudinal studies. For example, migrant farm workers tend to be a seasonally-interstate-mobile population, predominantly transnational, low socioeconomic status, low literacy and/or substantially monolingual - Spanish or Mexican indigenous dialect, and distrustful of surveys due to social-legal-political reasons.
Purpose: The specific aims of this project are to: 1) to bring together a team of experts on mobile populations to discuss sampling methodology issues with migrant farm workers as related to tobacco use; (2) produce a report on sampling methodology issues and solutions to researching migrant mobile populations both in the United States and transnationally, specifically migrant farm workers; (3) establish a research agenda for mobile populations focusing on U.S. migrant farm workers that may be used as a guide for funding agencies and investigators who wish to conduct studies with this population within the realm of tobacco control; and (4) strengthen and enhance a dissemination plan to maximize the distribution of the findings by synergizing key constituents communication channels, increasing knowledge uptake and facilitating implementation. The one-day meeting of 30 experts was held on March 14, 2008 at the California Endowment in Los Angeles, California. Meeting participants included scientists, key foundations and union leaders, and government agency representatives, as well as key community representatives and stakeholders who work directly with these populations.
Impact: TReND’s investigators will prepare a meeting report and will consult with key meeting members and participating organizations to develop and implement an efficient and expansive dissemination plan for distributing the meeting report. The goal of the dissemination plan is to ensure wide distribution to key audiences – scientist, advocate, private foundations, and federal government agencies, and impacted communities. The report will also include a comprehensive research agenda designed to address the methodological issues in conducting tobacco-related and other health research among migrant farm workers and ultimately help eliminate tobacco-related disparities and improve the overall health of this population. TReND’s investigators will also disseminate the significant meeting and report findings through peer-reviewed journal publications and presentations at major professional conferences.
