Correlation between different frequency of sudden death and the quality of life in Yunnan unexplained sudden death disease area / 中华地方病学杂志

ABSTRACT

Objective To investigate the relationship between the quality of life and different frequency of sudden death in Yunnan unexplained sudden death disease area.Methods According to the stratified cluster sampling method,728 individuals were selected as the respondents in Heqing County,Eryuan County of Dali Bai Autonomous Prefecture,and in Dayao County of Chuxiong Yi Autonomous Prefecture.According to the random sampling,649 individuals were selected as the control in Yongping County,Dali Bai Autonomous Prefecture.Data of the quality of life (WHOQOL-BREF version) were collected through household surveys.Analysis method including ANOVA,Chi-squared test and multilinear regression were used.Results Compared with the control population,the household income of population in the diseased area was not significantly different statistically (x2 =7.052,P ＞ 0.05).But the differences in education level and chronic disease situation were statistically significant (x2 =35.727,9.810,all P ＜ 0.05).According to the frequency of the sudden death,from one to four,the total scores of the quality of life,the scores of the physiology domain,the scores of the psychological domain,the scores of the environmental domain and the scores of the social relations domain (1 time54.30,13.74,14.43,11.21,14.91;2 times54.75,13.86,14.65,11.12,15.10;3 times52.40,13.21,13.76,11.00,14.41;4 times49.21,12.15,12.54,9.87,14.64)were all lower than those of the control group (56.03,14.11,14.78,11.88 and 15.26),the differences between two groups were statistically significant (x2 =41.88,25.75,41.07,35.07,8.08,all P ＜ 0.05);the total scores and each domain score of the quality of life were negatively correlated with the frequency of sudden death (the multi-variables regression coefficient were as follows-1.195,-0.341,-0.356,-0.314,and-0.185,all P ＜ 0.05).Conclusions The quality of life of those who have lived in Yunnan unexplained sudden death area is associated with the outbreak frequency of sudden death.Following increasing of the outbreak frequency of Yunnan unexplained sudden death,the quality of life of the population living in Yunnan unexplained sudden death area has decreased.
