| Objective: The dissertation aims to develop a mothod for evaluating the burden of disease (BOD) for urban residents in Chongqing, using disability-adjusted life years (DALY), an indicator presented recently, and evaluate their health status from different aspects with several indicators, and provide scientific guide for urban dweller's diseases prevention and treatment, and provide reference for reasonable application of these indicators through comparing the new and old indicators.Methods: With cluster sampling method,1,356,073 dwellers from four communities in urban area have been surveyed and the data concerning demography, surveillance of disease, and surveillance of death were collected. The level of mortality and spectrum of mortality are analysised by calculating crude death rate (CDR), standard mortality rate (SMR), potential years of life lost (PYLL), and standard potential years of life lost (SPYLL). DALY is caculated and the BOD from different causes over people was evaluated. Meanwhile the weaknesses as well as the strong points of these indicators are pointed out.Results:(1) It is indicated that ChongQing urban area has entered a senescence society for the persons over 65 years of age account for 8.07% of all the investigated urban residents. (2)Of all the investigated urban residents, CDR is 6.01‰(6.19% for male,5.82% for female),SMR is 5.22‰ (5.26% for male,5.16% for female). (3)The non-communicable diseases are the leading causes of deaths(deaths caused hereby accounting for 92.04% of all the deaths ),the second significant death causes are injuries(accounting for 6.60% of all the deaths),and the deaths caused by communicable, maternal, and perinatal diseases account for only 1.36% of all the deaths. (4) The five leading causes of mortality rate are (in descending order): malignant tumor, cerebrovascular disease, respiratory system disease, injuries, and cardiovascular disease. While malignant tumor is the leading cause of death for male and it is second significant cause of death for female. (5) The five leading causes among the malignant tumors are: lung cancer, liver cancer, Colon and rectum cancer, stomach cancer, and oesophagus cancer. And the order of these five malignant tumors is different for men and women. (6) The age-specified PYLL per 1,000 graphics shows that except the infant group, the group between 40 and 45 years of age constitute another peak. (7) Injuries and psyche diseases have an influence upon people's premature death. (8) The five leading causes of PYLL per 1,000 are (in descending order): lung cancer, liver cancer, stomach cancer, leukaemia and oesophagus cancer. Lung cancer, liver cancer, stomach cancer, and oesophagus cancer are more harmful to male than to female in shortening life span. (9)The ten leading causes of years of life lost due to premature mortality (YLL) per 1,000 are (in descending order): cerebrovascular disease, lung cance, chronic obstructive pulmonary disease (COPD), liver cancer, Colon and rectum cancer, road accident, stomach cancer, diabetes mellitus, cirrhosis of liver and drug use (the YLL rate of them altogether is 59.65% ),and lung cancer is the highest due to YLL for male while cerebrovascular disease is the highest for female. (10)The ten leading causes of years lived with disability (YLD) per 1,000 are (in descending order): COPD, lung cancer, hepatitis, homicide, road accident, falling injury, falling-body struck, breast cancer, cerebrovascular disease and traffic accidents caused by non-automobiles. And of all, five belong to injuries. (11) The ten leading causes of DALY per 1,000 are (in descending order): cerebrovascular disease, lung cancer, COPD, liver cancer, road accident, Colon and rectum cancer, drug use, stomach cancer, diabetes mellitus and cirrhosis of liver. (12) The ten leading causes of mortality rate, PYLL rate, and DALY rate are different each other for same sex. Cerebrovascular disease has the highest death rate among male, drug use has the highest PYLL rate and...
