2015—2017年内江市人群死亡漏报调查分析

Investigation and analysis of unreported deaths in Neijiang city from 2015 to 2017

目的了解2015—2017年内江市人群死亡漏报情况,分析内江市人群死亡水平。方法采用多阶段整群随机抽样方法随机抽取6520人,从死因监测系统以外渠道收集2015—2017年抽样点常驻居民死亡数据,与同期死因监测系统数据进行比对,标注漏报数据,获取漏报率。结果不同年份漏报率比较,差异无统计学意义(P=0.999)。男性漏报率为22.38%,低于女性的23.21%,差异有统计学意义(P=0.000)。不同监测类型地区漏报率比较,差异有统计学意义(P=0.000);非监测点地区漏报率高于国家级监测点地区,差异有统计学意义(P<0.05)。不同年龄段漏报率比较,差异无统计学意义(P=1.000);5岁以下儿童漏报率与5岁以上人群漏报率比较,差异无统计学意义(P=1.000);65岁以上人群与65岁以下人群漏报率比较,差异无统计学意义(P=1.000)。内江市人群死亡率均男性为1067.87/10万,高于女性的749.70/10万。结论内江市人群死亡登记存在明显的漏报,且存在性别和地区差异,应切实加强常规死因监测报告和管理,提高报告数据完整性,以真实客观评价内江市人群死亡水平。

Objective To understand the under-reporting of population death in Neijiang city from2015 to 2017,and to analyze the level of population death in Neijiang.Methods The multi-stage cluster random sampling method was adopted to randomly select 6520 people.The death data of residents in the sampling point from 2015 to 2017 were collected from other channels besides the cause of death monitoring system and compared with the data of the cause of death monitoring system in the same period.The under-reporting data were labeled,and the under-reporting rate was obtained.Results There was no significant difference in under-reporting rate between different years(P=0.999).The under-reporting rate was 22.38%in men,which was lower than 23.21%in women with statistically significant difference(P=0.000).There was significant difference in under-reporting rate among different monitoring types of areas(P=0.000).The under-reporting rate in non-monitoring areas was higher than that in national monitoring areas with statistically significant difference(P<0.05).There was no significant difference in under-reporting rate among different age groups(P=1.000),and there was no significant difference between<5 and≥5 years old groups(P=1.000),and there was no significant difference between≥65 and<65 years old groups(P=1.000).The mortality rate in males was higher than that in females(1067.87/100000 vs.749.70/100000).Conclusions There are obvious omissions in the death registration of people in Neijiang city,and there are gender and regional differences.Therefore,it is necessary to strengthen the routine monitoring report and management of death,improve the integrity of the report data,so as to truly and objectively evaluate the death level of people in Neijiang city.
