Health-related quality of life in Chinese people: A population-based survey of five cities in China

Abstract

Aims: The current study aimed at undertaking an investigation to describe health-related quality of life (HRQL) in Chinese people, with a Mandarin version of the 36-item short-form health survey (SF-36) validated. Methods: A total of 3,219 respondents were successfully interviewed under a randomized stratified multi-stage sampling design from April 2007 to January 2008 in five cities of mainland China. Self-finished interview method was applied and the Mandarin version of SF-36 was used for assessing HRQL. Results: As a result, the reliability and validity of SF-36 were acceptable, although some deviations from the hypothesized model still existed. The Chinese population scored higher than other populations in five of the eight SF-36 scales and Chinese men scored higher than women in six of the eight SF-36 scales. Conclusions: Basically, the Mandarin version of SF-36 is a reliable instrument, although minor modifications are needed. The health-related quality of life in Chinese people were quite high based on the sample of five cities in China; further research is needed to establish the countrywide norm of health-related quality of life in mainland China. © 2011, the Nordic Societies of Public Health.
