Health-Related Quality of Life of Chinese Earthquake Survivors: A Case Study of Five Hard-Hit Disaster Counties in Sichuan

Abstract

As one of the most destructive natural disasters, earthquakes affect the health of survivors. The devastating earthquakes that hit Sichuan, China have aroused the concern of domestic and international scholars. The health-related quality of life (HRQOL) of survivors also requires substantial research. Studies on impact factors, such as gender, age, monthly income, and education, have become controversial. The subjects in this study are the people of five hard-hit disaster counties in Sichuan Province, namely, Wenchuan, Qingchuan, Mianzhu, Lushan, and Dujiangyan. A preliminary survey was conducted in May and June 2013 in areas badly hit by the earthquake in Sichuan, China. A total of 2000 questionnaires were distributed, and 1672 of which were received, yielding a recovery rate of 83.6 %. To further complement and corroborate the conclusions, a follow-up survey was conducted in October and November 2013, where 1526 effective questionnaires were received. The analysis in this paper is mainly based on the first survey, and the collected data from the follow-up survey were used to perform a supplementary analysis. By analyzing data from five hard-hit areas in Sichuan and by establishing models, we drew the following conclusions: The results of analysis of variance and Tukey’s honestly significant difference tests revealed the following results. First, the results of two investigations indicate the HRQOL of earthquake survivors is relatively poor, especially in terms of general health (GH), mental health (MH), social functioning (SF), etc. However, results of the second survey indicate that the scores of all domains (except GH) have increased significantly, with the SF having the most significant increase. Second, the HRQOL scores of men are higher than those of women. Individuals with higher education or monthly income have higher HRQOL scores than those with lower education or income. Moreover, younger survivors have higher HRQOL scores than older survivors. Third, a positive correlation exists among the HRQOL domains of all survivors. Among all domains, the PF, RP, GH, MH, and VT of survivors have a very strong correlation. In addition, SF, BP, MH, and VT have a strong correlation. Other variables have a relatively weak correlation.
