Migratory and seasonal agricultural workers fill the labor needs of United States farmers. Although migrant workers are a culturally and ethnically diverse population, presently, they are predominantly immigrants of Hispanic ethnicity. Migrant farm workers are increasingly young, financially impoverished, male, undocumented immigrants from Mexico. Families with children constitute 45% of this population. The ecological context of migrant children's lives is characterized by poverty, social isolation, heightened inter- and intra-national mobility, limited protections from occupational safety and health legislation, and health access barriers. Moreover, the linkage of citizenship and immigration status to the receipt of public insurance and selected social services benefits has the potential to increase access barriers for migrant workers and their families. Despite these obvious vulnerabilities, few health services research studies address this population. Most of what is known relates to adults, with very little known about migrant children's health services utilization patterns or health morbidities. In the emergency department setting, the differential approach required to care for children, as compared to adults, must be modified further in order to address the unique needs of this vulnerable population. The effective delivery of acute care to the children of migratory agricultural workers requires awareness of and attention to their unique health access barriers, issues of continuity and compliance with care, and their unique health and injury risks. © 2004 Elsevier Inc.
