Global health initiatives are most effective when they communicate in local languages. Using local languages respects the identities and cultures of communities and allows people to understand health messages, learn effectively, and make informed decisions. Mothers in particular benefit from materials in their home language to maintain health practices. SIL has experience developing appropriate health materials, like trauma healing and HIV/AIDS programs, in over 120 languages. They also help check that materials are comprehensible and develop key health terms. Initiatives should consider local language needs to most effectively serve vulnerable groups and create behavior changes that improve health.
