An analysis reported in the Journal of Immigrant Minority Health suggests that there is a strong association between being born in a developed country as compared to a developing country and having diagnosed asthma. The reasons for this association are not clear. To the extent that the causes can be determined, they might shed light on why some children develop asthma and others do not. One hypothesis is that native and foreign born children may respond differently to environmental stressors (pests and SES). There is a need for more research to explore this possibility further.
