Abstract:
Objective To analyze the characteristics of death and potential life loss caused by malignant tumors in Anhui province.
Methods By using the following indexes: mortality rate (MR), standardized mortality rate (SMR), potential years of life lost (PYLL), potential years of life lost rate (PYLLR) and average years of life lost (AYLL), this paper summarizes the age, gender and area specific demographic characteristics, the malignant tumor mortality characteristics and related life loss in residents in Anhui province during 2013–2016. The data was been adjusted by the results of under-reporting investigation.
Results The ageing of population became more serious in Anhui during 2013–2016. The MR of malignant tumor increased year by year (χ2=55.868, P=0.001). The MR was higher than the national level, but it was normal. The annual average MR was 170.02/100 000, the SMR was 117.46/100 000. The MR in males (224.89/100 000) was higher than that in females (114.30/100 000) (U=104.031, P=0.001). The difference in MR of malignant tumor between urban area (169.74/100 000) and rural area (168.66/100 000) had no significance (U=1.018, P=0.309). The MRs of Huaibei, Jianghuai and Jiangnan were 151.05/100 000, 191.07/100 000 and 176.07/100 000 respectively, there was statistical difference (χ2=1 165.196, P=0.001). The SMR in Jianghuai was highest, followed by that in Huaibei and in Jiangnan. The PYLL caused by malignant tumor also increased year by year, the average annual PYLL was 161 009.10 person years, the standardized PYLL was 144 399.80 person years, the PYLLR was 10.73‰ and the AYLL was 6.31 year/person. Most malignant tumor deaths occurred in people aged ≥60 years. The MR increased significantly after the age of 45 years. The PYLL was high in age group 30-60 years. The top five death causes of malignant tumor were lung cancer, gastric cancer, liver cancer, esophageal cancer and colorectal cancer, and the top five causes resulting high PYLL were liver cancer, lung cancer, gastric cancer, leukemia and colorectal cancer.
Conclusion Anhui would face a heavy burden of malignant tumor in the future. Lung cancer, liver cancer, gastric cancer, esophageal cancer, leukaemia and colorectal cancer are the main malignant tumors which affect people's health in Anhui. In addition to focusing on key areas and key populations, we should also focus on the prevention and control of risk factors, strengthen health education, fully promote healthy lifestyle, and establish a multi-sectoral prevention and treatment mechanism.
