The purpose of this qualitative study was to explore how cultural differences influence the healthcare-seeking behaviors of older Iranian immigrants in the United States. Cultural differences were examined in a variety of areas, including definitions and perceptions of health, illness, and care. Using a phenomenological methodology, in-depth, semi-structured interviews were conducted with older Iranian immigrants. The findings of this study showed that participants' definitions of health, illness, and care differ significantly from mainstream Western definitions. An understanding of these cultural differences helps explain why older Iranian immigrants may or may not seek healthcare when they need it in the United States. Recommendations for change include cultural training for medical staff and the use of cultural brokers.
