Comparison of health-related quality of life between the Han and Yi ethnicity elderly in the Yi autonomous areas of Yunnan Province

Background: The purpose of this research was to assess the health-related quality of life (HRQOL) and functional abilities of Yi and Han elderly who resided in Yi Autonomous prefecture or Counties in Yunnan Province, as well as to compare their differences in HRQOL, functional abilities and other factors. Methods: A total of 1636 older subjects, which included 863 Han and 773 Yi, were recruited from 10 Yi Autonomous regions. Their HRQOL and functional capabilities were assessed by the MOS 36-Item Short Form Health Survey (SF-36), activities of daily living (ADL), and instrumental activities of daily living (IADL) scales. Results: The Han elderly performed better in every domain of SF-36 than the Yi elderly. Both of the two ethnic groups could perform their ADL independently but the Yi elderly showed greater dependency in IADL abilities. The HRQOL was positively associated with their ADL, IADL, and education levels. Moreover, age, health insurance status, and living arrangement were negatively correlated with HRQOL. Conclusion: The HRQOL and IADL capabilities of the Han elderly were higher than that of the Yi counterparts in the Yi Autonomous regions. The HRQOL of both the two ethnic groups was positively connected with ADL, IADL abilities as well as education levels, whereas it was negatively correlated with age and health insurance. The elderly-care policy on the Yi autonomous areas should focus more on the HRQOL, ADL improvement, education background, age needs, and health insurance, etc.
