Objective To conduct the application research on health utility in the residents of Wuhu as a representative third-tier city by using the European quality of life 5-dimensions(EQ-5D) for analyzing the relationships between different time trade-off(TTO) conversion model and other factors,and comparing the goodness of fit between the Japan(JP) TTO conversion model with the United Kingdom(UK) TTO conversion model. Methods By using the questionnaire survey method,EQ-5D was adopted to measure the survival quality in the residents of Wuhu as a representative third-tier city. Then the TTO conversion models of Japan and UK were utilized to calculate the health index of the research subjects. The correlation between the demographic factors with the visual analogue scales(EQ-VAS) score was analyzed by using the SPSS19.0 software. The index for testing the goodness of fit model was calculated as well. Results 782 citizens were conducted the questionnaire survey,the ratio of male to female basically reached 1:1. By using different TTO models to calculate the health index score,the score of Japanese TTO model was higher than that of the UK TTO model,moreover these two kinds of TTO conversion model had certain correlation with the age,cultural level and EQ-VAS. Calculating the values of R2,F,AIC and BIC and conducting comparison found that the goodness of fit of JP model was better than that of UK model. Conclusion Different EQ-5D TTO transform models have slight difference in the health indexes measurement of residents in Wuhu as a representative third-tier city. Comparing the indexes for testing the goodness of fit for the two kinds of model finds that the JP model is more suitable for the study population than the UK model. [ABSTRACT FROM AUTHOR]
