Elderly people from ethnic minority groups often experience different barriers in accessing health services. Studies have typically focused on combined groups of elderly immigrants or on large ethno-cultural minorities such as the Chinese in Canada, or African-Americans and Hispanics in the U.S. This study aimed to examine the types and factor structure of barriers to using health services experienced by aging South Asian immigrants in Calgary, Alberta, Canada. A telephone survey was used to collect data from a random sample of South Asian immigrants aged 55 years and older. Principal component analysis revealed four major types of barriers: cultural incompatibility, personal attitudes, administrative problems in delivery, and circumstantial challenges.
