我国老年人伤害死亡率的meta分析

Mortality of injuries among the elderly in China: a meta-analysis

目的综合评价我国老年人伤害死亡率的情况,为预防老年人伤害提供依据。方法系统检索中国知网、万方数据库、中国生物医学文献数据库、维普及PubMed数据库,收集2007-2017年发表的与我国老年人伤害死亡率相关的文献,采用meta分析的方法,计算合并的伤害死亡率,分性别、城乡进行亚组分析,并对结果进行敏感性分析和发表偏倚的评价。结果共纳入符合标准的文献23篇,总样本含量32591537人,老年人合并伤害死亡率为:173.93/10万(95%CI:155.20/10万~192.67/10万),男性伤害死亡率(178.92/10万)高于女性(159.08/10万),农村老年人伤害死亡率(244.27/10万)高于城市(164.34/10万),二者差别均有统计学意义(P<0.001)。结论我国老年人伤害死亡率处于较高水平,性别、城乡之间存在差异,应采取针对性干预措施,降低老年人伤害死亡率。

Objective To synthetically evaluate the mortality of injuries among the elderly in China so as to provide a basis for prevention of injuries in the elderly.Methods The published articles about the injury mortality in the elderly in China from 2007 to 2017 were collected from China National Knowledge Infrastructure (CNKI), Wanfang Databases, Chinese Biological and Medical Database (CBM), VIP Information Resource System and PubMed Databases. Meta-analysis was used to calculate the combined injury mortality, subgroup analysis was conducted according to genders and urban & rural areas, and sensitivity analysis and bias evaluation of the results were performed.Results Twenty-three valid articles were included, with a total sample size of 32,591,537 senior citizens. The combined injury mortality of the elderly was 173.93/100,000 (95%CI:155.20/100,000-192.67/100,000). The injury mortality was higher in the male elderly than in the female elderly (178.92/100,000 vs. 159.08/100,000) as well as higher in the rural elderly than in the urban elderly (244.27/100,000 vs. 164.34/100,000), showing statistically significant differences (both P<0.001).Conclusions The injury mortality of the elderly in China is at a high level, and there are differences between gendersas well as between urban and rural areas. It is necessary to adopt targeted intervention measures so as to reduce their injury mortality.
