Advancing the Health of Migrant and Seasonal Farmworkers in the United States: Identifying Gaps in the Existing Literature, 2021

There are profound health inequities for agricultural workers. We sought to assess the literature on migrant and seasonal farmworker health with an eye toward health promotion interventions, special populations, use of community health workers (CHWs), and technology. We conducted a systematic mapping review by searching five databases in March 2021. Using quantitative content analysis after establishing interrater reliability, we coded titles and abstracts to assess 13 topics and six characteristics of the research such as its focus on health promotion, use of technology, and inclusion of CHWs. We identified 1,083 records. Just 8.2% of records described or evaluated a health promotion effort to intervene in farmworker well-being and even fewer (4.2%) examined unique populations of farmworkers such as indigenous farmworkers (n = 11) or sexual minority farmworkers (n = 1). A small body of literature focused on the role of CHWs or promotores most frequently described their role in implementing health interventions. The literature on farmworker health has gaps regarding health promotion interventions, special populations, and integration of CHWs into research projects. We offer suggestions to fill in identified gaps in the literature.
