Abstract:

BACKGROUND: Health quality of life survey in the border minority has a practical and political role to improve the public health-care system of China. Correlation analysis of body shape and health quality of life in Gin residents from the Sino-Vietnamese border is a typical representative.
OBJECTIVE: To find the main components of body composition influencing health quality of life by the related analysis and corresponding matrix after rotation and then to evaluate the correlation between the body shape and health quality of life in Gin residents from the Sino-Vietnamese border.
METHODS: From July 2009 to April 2011, the in-situ investigation, testing and health questionnaire were used for a cross-sectional survey in 361 male Gin residents from the Sino-Vietnamese border, aged 20-35 years. The response rate for the questionnaire was 100%. SPSS 17.0 software was applied to analyze the related indicators, and then initial factor model and rotated factor model were established for quantitative correlation analysis between the morphological characteristics and health quality of life in Gin residents from the Sino-Vietnamese border.
RESULTS AND CONCLUSION: All the data were included in result analysis. Correlation analysis showed a higher relevance among indicators, of which, there was a higher correlation in 21 coefficients (P < 0.01), and correlation in 14 coefficients (P < 0.05). Correlation coefficients accounted for 44.48%. The main components influencing the body shape and health quality of life in border residents were health life basic quality as the first, life happiness index as the second, life happiness as the third, and nutrition development as the fourth. Using dimension reduction method, we can observe the extremely complex correlation between variables to objectively evaluate the health quality of life of the minority populations of the border. This method is characterized as practicality, generalizability and replicability.
