Incidence and fatality of serious suicide attempts in a predominantly rural population in Shandong, China: a public health surveillance study

Objectives: To estimate the incidence of serious suicide attempts (SSAs, defined as suicide attempts resulting in either death or hospitalisation) and to examine factors associated with fatality among these attempters. Design: A surveillance study of incidence and mortality. Linked data from two public health surveillance systems were analysed. Setting: Three selected counties in Shandong, China. Participants: All residents in the three selected counties. Outcome: measures Incidence rate (per 100 000 person-years) and case fatality rate (%). Methods: Records of suicide deaths and hospitalisations that occurred among residents in selected counties during 2009–2011 (5 623 323 person-years) were extracted from electronic databases of the Disease Surveillance Points (DSP) system and the Injury Surveillance System (ISS) and were linked by name, sex, residence and time of suicide attempt. A multiple logistic regression model was developed to examine the factors associated with a higher or low...

研究目的：评估严重自杀未遂（Serious Suicide Attempts, SSAs，定义为导致死亡或住院的自杀未遂行为）的发生率，并分析此类自杀未遂者中与死亡结局相关的影响因素。研究设计：一项发生率与死亡率监测研究。对两个公共卫生监测系统的关联数据进行分析。研究场景：中国山东省三个选定县区。研究对象：上述三个选定县区的全体常住居民。结局指标：发生率（单位：每10万人年）与病例病死率（%）。研究方法：提取2009-2011年间（共计5623323人年）选定县区居民中发生的自杀死亡与住院记录，数据来源于疾病监测点（Disease Surveillance Points, DSP）系统与伤害监测系统（Injury Surveillance System, ISS）的电子数据库，并通过姓名、性别、居住地及自杀未遂发生时间进行关联匹配。构建多因素logistic回归模型，分析与较高或较低……相关的影响因素。
