The Social Gradient in Mental Health and Well-Being for Indigenous Older Adults Living in Rural Areas: A Cross-Sectional Comparison With Rural Non-indigenous Population in Chile.

Objectives: To compare differences in depression, loneliness and personal well-being in a sample made up of indigenous (Aymara and Mapuche) and non-indigenous older people resident in original rural territories. Methods: A cross-sectional study involving 800 older adults living in a rural context in Chile, of whom 201 were Aymara, 368 Mapuche and 231 non-indigenous. Validated instruments were included for depression, loneliness and personal well-being (outcome variables). Ordinary least squares regression analyses were performed. Results: Membership of an indigenous group was significantly associated with lower scores for depression and loneliness and higher scores for personal well-being. The interactions of severe deprivation and housing deprivation with indigenous group membership were significantly associated with lower loneliness scores and higher personal well-being scores for Aymara and Mapuche participants. Discussion: Native rural settings and territories may offer a degree of protection to indigenous peoples. Cultural continuity enhanced by rural areas would produce a culturally constructed resilience against deprivation.
