GEMINI stands for Generational Differences in Environmental Exposures caused by Migration: Impact on Incidence of Inflammatory Disease. This research study addresses a growing concern in the South Asian Canadian communities.  These communities are experiencing a dramatic increase in the incidences of chronic inflammatory disease upon exposure to the North American environment. The team are investigating how the microbiome might change when people migrate from South Asia to Toronto and how this could contribute to chronic disease. The purpose of this research is to also understand health beliefs, health care needs and access to health care services among 1st and 2nd generation South Asian Canadians living in the Greater Toronto Area. We encourage individuals of South Asian descent to join the effort.Funded by Connaught, CIHR.
