Analysis of main causes of deaths and potential years of life lost among residents in Guangzhou City,2011

Objective To analyze the main causes of death and the potential years of life lost(PYLL) among residents in Guangzhou in 2011.Methods The population data in 2011 were provided by the Health Bureau of Guangzhou City.The data of death causes of Guangzhou in 2011 were obtained from the registry and report system of death causes.The causes of death were classified according to ICD-10.The leading causes of death and the potential life loss among residents in Guangzhou in 2011 were evaluated by the mortality rate,life expectancy,cause-deleted life expectancy and PYLL.Results There were 44 262 cases of deaths in Guangzhou in 2011.The mortality rate was 544.47 /100 000(standardized rate was 336.45 /100 000) in 2011.The mortality rates were 612.50 /100 000(standardized rate was 431.12 /100 000) in male and 474.66 /100 000(standardized rate was 248.26 /100 000) in female.The mortality in male was significantly higher than that in female(P 0.01).The six leading causes of death were malignant neoplasms,heart diseases,respiratory diseases,cerebrovascular diseases,acatalepsy,and injury,and their death rates were 133.44 /100 000,101.82 /100 000,100.68 /100 000,73.70 /100 000,31.54 /100 000,and 26.53 /100 000,respectively.The life expectancy was 80.83 years.It would increase 3.81,2.78,and 2.73 years if removing the three leading causes of death.Their PYLL were 107 716.00,81 414.00,81 106.50,61 978.50,26 523.00,and 22 232.50 years.Conclusion The chronic diseases,especially,extraordinary malignant neoplasms,heart diseases,and respiratory diseases were the main causes of deaths in Guangzhou in 2011.The prevention and treatment of malignant neoplasms,heart diseases,respiratory diseases should be the focus of health care in Guangzhou.In particular,the prevention of tumorigenesis and the early diagnosis and treatment are crucial to the reduction of population life lost.
