目的 了解兰州市居民伤害死亡趋势及早死减寿水平,为伤害防控提供依据.方法 收集2014-2022年兰州市居民伤害死亡数据,采用粗死亡率、标化死亡率、早死概率、潜在减寿年数(potential years of life lost,PYLL)、减寿率(potential years of life lost rate,PYLLR)和年度变化百分比(annual percentage change,APC)等指标进行伤害死亡趋势及早死减寿分析.结果 2014-2022年兰州市居民伤害累计死亡8 177例,粗死亡率为24.21/10万,标化死亡率为23.01/10万.男性粗死亡率为33.72/10万,标化死亡率为32.28/10万;女性粗死亡率为14.20/10万,标化死亡率为13.30/10万,男性死亡率均高于女性,差异有统计学意义(x2=1 331.85,P＜0.01).2014-2022年兰州市居民伤害类别死因前三位依次是交通事故、跌倒、自杀,死亡率分别为9.99/10万、4.64/10万和2.94/10万.2014-2022年兰州市居民伤害早死概率为1.12％,由2014年的1.65％下降至2022年的0.62％(APC=-9.80％),差异有统计学意义(t=-5.04,P＜0.01).2014-2022年兰州市居民因由伤害导致的PYLL累计236442人年,其中男性173 283人年,女性63 159人年.PYLL由2014年的47 178人年下降至2022年的13 049人年(APC=-12.51％),趋势变化差异有统计学意义(t=-6.27,P＜0.01).由伤害导致的PYLLR为7.09‰,男性为10.12‰,女性为3.89‰.PYLLR由2014年的12.96‰下降至2022年的2.99‰(APC=-6.71％),趋势变化差异有统计学意义(t=-5.65,P＜0.01).结论 2014-2022年兰州市居民伤害死亡和早死寿命损失的主要伤害类别为交通事故、跌倒、自杀,男性和≥65岁老年人群是兰州市伤害重点人群,应予以重点关注.
Trends in injury-related mortality and premature death analysis in Lanzhou City,2014-2022
Objective To investigate the trend in injury-related mortality and premature death levels among residents in Lanzhou City from 2014 to 2022 and to provide a basis for injury prevention and control.Methods Injury-related mortality data for residents in Lanzhou City from 2014 to 2022 were collected.Various indicators such as crude mortality rate,standardized mortality rate,premature death probability,potential years of life loss(PYLL),potential years of life lost rate(PYLLR),and annual percentage change(APC)were used to analyze the trends in injury-related mortality and premature death.Results From 2014 to 2022,there were a total of 8 177 cumulative injury-related deaths among residents in Lanzhou City,with a crude mortality rate of 24.21/100 000 and a standardized mortality rate of 23.01/100 000.The crude mortality rate for males was 33.72/100 000,with a standardized mortality rate of 32.28/100 000,while for females,the crude death rate was 14.20/100 000,with a standardized death rate of 13.30/100 000.From 2014 to 2022,the top three causes of injury among residents in Lanzhou were traffic accidents,falls,and suicides,with mortality rates of 9.99/100 000,4.64/100 000,and 2.94/100 000,respectively.From 2014 to 2022,the probability of premature death from injury of Lanzhou residents was 1.12％,which decreased from 1.65％in 2014 to 0.62％in 2022(APC=-9.80％)and the difference was statistically significant(t=-5.04,P＜0.01).According to the analysis of various injury categories,the PYLL caused by injury of Lanzhou residents accumulated 236 442 person-years in nine years,including 173 283 person-years for males and 63 159 person-years for females.The PYLL decreased from 47 178 person-years in 2014 to 13 049 person-years in 2022(APC=-12.51％),and the difference in trend was statistically significant(t=-6.27,P＜0.01).The PYLLR due to injury-related deaths was 7.09‰,with a rate of 10.12‰ for men and 3.89‰ for females.The PYLLR decreased from 12.96‰ in 2014 to 2.99‰ in 2022(APC=-6.71％),showing a statistically significant difference in trend change(t=-5.65,P＜0.01).Conclusions Traffic accidents,falls,and suicides were the main categories of injury-related deaths and premature life loss in Lanzhou City from 2014 to 2022.Males and the elderly population aged 65 and above were identified as key populations for injury prevention and control in Lanzhou City.
