Abstract:
Objective To analyze the trends of suicide mortality and disease burden among the elderly aged 60 and above in Chongqing from 2012 to 2023,providing evidence for targeted interventions.Methods Death cases of elderly aged 60 and above were extracted from death registration between 2012 and 2023 according to death records(International Statistical Classification of Diseases and Related Health Problems,10th version:X60-X84,Y87).The data were analyzed to calculate indicators such as the mortality rate,standardized mortality rate,years of life lost(YLL)rate,and average years of life lost(AYLL),and the composition ratio of different causes of death with using Excel 2010 and SPSS 26.0.The comparison of mortality rates between male and female,urban and rural area was conducted using the x2 test.The trend changes of the rates were expressed by the annual percentage change(APC)and the average annual percentage change(AAPC).Results From 2012 to 2023,the suicide mortality rate and standardized mortality rate of the elderly aged 60 and above generally showed a downward trend,decreasing by 3.54%and 4.02%,respectively(P<0.05).From 2012 to 2016,the suicide mortality rate increased by an average of 4.53%per year,and from 2016 to 2021,it decreased by an average of 8.91%per year,and both trends were significant(P<0.05).Only in 2020 and 2022,the male suicide mortality rate was significantly higher than that of females(P<0.05).From 2012 to 2023,the suicide mortality rate and standardized mortality rate of males and females decreased by an average of 2.86%,3.44%,4.21%,and 4.69%per year respectively,and the trends were significant(P<0.05).The suicide mortality rate of the elderly aged 60 and above in rural areas was significantly higher than that in urban areas over the years(P<0.05).From 2012 to 2023,the suicide mortality rate and standardized mortality rate in urban areas remained relatively stable(P>0.05),while the suicide mortality rate and standardized mortality rate of the elderly aged 60 and above in rural areas decreased by an average of 3.44%and 4.02%per year respectively,and the trends were significant(P<0.05).The YLL rate and AYLL caused by suicide among the elderly aged 60 and above decreased from 3.03‰ and 18.54 years in 2012 to 2.26‰ and 17.50 years in 2023 respectively,and the AAPC were-4.02%and-0.60%respectively,and the trends were significant(P<0.05).By comparing the composition of deaths by different suicide methods over the years,it was found that the proportion of deaths due to pesticide poisoning showed a downward trend,while the proportions of deaths by hanging,jumping from a height,and drowning showed an upward trend.Conclusion The suicide mortality rate of the elderly aged 60 and above in Chongqing is relatively high.Although demonstrating an overall downward trend,enhanced efforts toward early identification and intervention for elderly suicide should be enhanced.
