中国老年人伤害发生率的Meta分析

Incidence of injuries among the elderly in China:a meta analysis

目的采用Meta分析评价中国老年人伤害发生率状况,为老年人伤害的预防提供依据。方法系统检索中国知网、万方数据资源系统、维普中文科技期刊全文数据库、PubMed数据库,收集2007~2017年收录的关于中国老年人伤害发生率的相关文献;采用Stata 12.0软件对纳入的文献进行Meta分析。结果筛选出文献26篇。调查140 931人,伤害发生例数为8 370例,伤害发生率为8.7%(95%CI=7.6%~9.9%),其中跌落伤最高,为3.8%(95%CI=3.3%~4.3%);亚组分析显示,女性伤害发生率(8.7%)高于男性(5.9%)(P<0.01);城镇老年人伤害发生率(8.6%)高于农村(7.1%)(P<0.01);东部、中部、西部地区老年人伤害发生率分别为10.6%、9.5%、6.7%(P<0.01)。结论我国老年人伤害发生率在性别、城乡、研究地区间存在差异。女性伤害发生率高于男性;城镇伤害发生率高于农村;东部地区伤害发生率高于中、西部地区。

Objective To estimate the incidence of injuries among the elderly in China using meta-analysis,so as to provide basis for prevention of elderly injuries. Methods CNKI,WangFang database,VIP and PubMed database were searched to collect the studies that were included during 2007-2017 about the injuries incidence among the elderly in China.Meta-analysis was performed with Stata 12.0. Results A total of 26 papers were included in this study.The total number of participants investigated was 140 931,with 8 370 injuries cases identified.The pooled incidence of injuries was 8.7%（95%CI =7.6%-9.9%）.Subgroup analysis showed the following results：the women had a higher incidence（8.7%）than the men（5.9%）,the difference was statistically significant（P〈0.01）;The incidence of injuries among the elderly in urban areas was 8.6%,higher than 7.1%in rural areas,the difference was statistically significant（P〈0.01）;the incidence of injuries among the elderly was 10.6%,9.5% and 6.7%in the eastern,central and western region（P〈0.01）. Conclusion The incidence of injuries among the elderly has differences in gender,urban/rural,research region in China.The women have a higher incidence than the men;the incidence of injuries in urban areas is higher than that in rural areas;the eastern region has the highest incidence of injuries.
