ABSTRACT
OBJECTIVES: Health-related quality of life (HRQOL) is a complicated concept that can be measured using multiple health items. Although HRQOL is closely associated with people's subjective assessment of their own health, a limited number of studies have investigated which health items are considered most important and relevant by the general population. Even fewer empirical studies have investigated how HRQOL is understood in non-Western populations. This study used multidimensional unfolding analysis in a Chinese general population to explore the constructs of HRQOL. METHODS: A scoping review of Chinese generic HRQOL measures and a series of qualitative interviews produced a list of 42 potentially important health items in a Chinese cultural setting; 110 Chinese participants in face-to-face interviews ranked the health items from most important to least important. Responses were coded into a rectangular 110 × 42 matrix, and multidimensional unfolding was conducted to analyze participants' preferences for health items. RESULTS: It was found that demographic characteristics and one's health condition affected views of HRQOL. Meanwhile, 3 health items were considered to be most important across the whole sample: sleep quality, body constitution, and spiritual appearance. CONCLUSION: This study used a novel approach to explore how people coming from a Chinese cultural setting may perceive HRQOL and which aspects of HRQOL are most important to them. The study shows that multidimensional unfolding is a feasible approach to assess preferences in a general population. Future studies using this approach are recommended to further explore the constructs of HRQOL in other general populations.

PURPOSE: To measure, describe and analyse regional differences in health-related quality of life measured by EQ-5D in China. Data were obtained via face-to-face interviews on a national representative sample (n=120,703, 15-103 years). The EQ-5D instrument was used to measure health status. RESULTS: Rural areas had worse health status than urban areas. Health status was worst in western areas and best in eastern areas, and such disparities were profounder in rural areas. In urban areas, health status was best in middle-sized cities. In rural areas, health status increased with the economic development level of a county. CONCLUSION: Our study enhances understanding of the urban-rural differences and east-middle-west differences in health and sheds light on inequalities in health status between different city categories in the urban areas and county categories in the rural areas.
