Challenges and solutions in immigrant occupational health in the United States: a literature review and comparative analysis.

In the United States, the occupational health of immigrant workers has been studied mainly in terms of health disparities. Possible causes of disparities in immigrant occupational health fell into seven categories. Solutions centered on the keywords in each category were inferred. Some businesses and community groups achieved positive results by simultaneously dealing with multiple aforementioned categories. Occupational health professionals have to take each of seven categories into account to improve immigrant occupational health. Even the United States-a developed country facing many migrant occupational health problems-needs further research and better data. To address this issue in Japan, we too need more data and further research on immigrants, along with efforts by businesses and community groups.
