Trend of mortality of fall in Ningbo / 预防医学

ABSTRACT

Objective@#To analyze the trend of the fall death rate in Ningbo,and to provide reference for prevention and control of fall death. @*Methods @#The data of fall mortality in Ningbo from 2002 to 2018 was collected to calculate the crude mortality rate,standardized mortality rate,age specific mortality rate and the proportion of fall death types. Joint Point Regression was used to evaluate annual percentage change（APC）of fall mortality. @*Results @#The average annual crude and standardized mortality rate of fall in Ningbo was 16.81/100 000 and 11.18/100 000,showing an upward trend from 2002 to 2018（P<0.05）. The standardized mortality rate of fall was 11.57/100 000 in men and 10.41/100 000 in women,and the difference was statistically significant（P<0.05）,both showing an upward trend from 2002 to 2018（P<0.05）. The standardized mortality rate of fall was 11.07/100 000 in urban residents and 11.25/100 000 in rural residents,and the difference was statistically significant（P<0.05）,both showing an upward trend from 2002 to 2018（P<0.05）. The mortality rate of fall increased with age（P<0.05）. The mortality rate of fall showed a small peak in children less than five years old（1.81/100 000）,and began to rise rapidly in people aged 65 years or over and peaked again in people aged 85 years or over. There were 11 141 cases died of falling on the same plane,accounting for 68.25%. Fall deaths occurred mainly at home,with 11 829 cases（72.46%）.@*Conclusion @#The mortality rate of fall in Ningbo increased from 2002 to 2018. The males,urban residents,people aged less than five years and aged 65 years or older have high risk of death from fall,who were targets for prevention and control strategies of fall.
