Abstract

OBJECTIVE: To investigate the changing trend of mortality and the spectrum regarding causes of death in the population of Hunan, and to analyze the health-related major diseases. METHODS: With retrospective study method, a sample survey on causes of death and the related information was carried out from 2004 to 2005 among the residents in Hunan province. Results were compared with the data from a retrospective survey on causes of death in Hunan during 1973 - 1975 and 1990 - 1992, respectively. RESULTS: The crude mortality rates and the standardized mortality ratios (SMR) of the reisidents in Hunan were 901.59/100 000 and 865.14/100 000 during the period of 1973 - 1975 while 588.64/100 000 and 537.42/100 000 druing the period of 1990 - 1992, and 608.27/100 000 and 413.67/100 000 during the period of 2004 - 2005, respectively. During the past 30 years, the SMR of the residents in Hunan decreased by 52.18% and the descending range from the rural areas was more than that of the urban areas, and higher in females than in males. The death proportion of infectious diseases, maternal and perinatal diseases, nutritional deficiencies decreased significantly (P < 0.01), but the death proportion of chronic non-communicable diseases increased significantly (P < 0.01). The changing ranges of the former two proportions were both larger in the rural areas than those in the urban areas. The highest proportions of deaths due to injury and poisoning during the past 30 years were both seen in the 5 year olds, followed by the age groups of 25 year olds (P < 0.01). During the period of 2004 - 2005, the death proportion of all the infectious diseases, maternal/perinatal diseases and nutritional deficiencies was 8.01% altogether, and those of chronic non-communicable diseases, injury and poisoning were 80.66% and 11.33%, respectively. During the past 30 years, the SMR of the three kinds of diseases all significantly decreased, more significantly seen in infectious diseases, maternal and perinatal diseases, and nutritional deficiencies but less in chronic non-communicable diseases. Among the death cases of chronic non-communicable diseases, the SMR of cerebrovascular disease, malignant tumor, and heart disease showed an increasing tendency and the sequences of them had been advanced to the first, the second, and the fourth in the death ranking during the period of 2004 - 2005, respectively. CONCLUSION: The SMRs of the residents in the urban and rural areas from Hunan province showed a declining tendency. Cardiovascular, cerebrovascular diseases and malignant tumors had become the important diseases affecting the health of the people, while injury and poisoning had otherwise topped the causes of death among children and adolescents in Hunan province.
