Suicide in elementary school-aged children is not well studied, despite a recent increase in the suicide rate among US black children. The objectives of this study were to describe characteristics and precipitating circumstances of suicide in elementary school-aged children relative to early adolescent decedents and identify potential within-group racial differences.
We analyzed National Violent Death Reporting System (NVDRS) surveillance data capturing suicide deaths from 2003 to 2012 for 17 US states. Participants included all suicide decedents aged 5 to 14 years (N = 693). Age group comparisons (5-11 years and 12-14 years) were conducted by using the χ test or Fisher's exact test, as appropriate.
Compared with early adolescents who died by suicide, children who died by suicide were more commonly male, black, died by hanging/strangulation/suffocation, and died at home. Children who died by suicide more often experienced relationship problems with family members/friends (60.3% vs 46.0%; P = .02) and less often experienced boyfriend/girlfriend problems (0% vs 16.0%; P < .001) or left a suicide note (7.7% vs 30.2%; P < .001). Among suicide decedents with known mental health problems (n = 210), childhood decedents more often experienced attention-deficit disorder with or without hyperactivity (59.3% vs 29.0%; P = .002) and less often experienced depression/dysthymia (33.3% vs 65.6%; P = .001) compared with early adolescent decedents.
These findings raise questions about impulsive responding to psychosocial adversity in younger suicide decedents, and they suggest a need for both common and developmentally-specific suicide prevention strategies during the elementary school-aged and early adolescent years. Further research should investigate factors associated with the recent increase in suicide rates among black children.
尽管美国黑人儿童自杀率最近有所上升,但对小学适龄儿童自杀的研究尚不充分。本研究的目的是描述小学适龄儿童自杀相对于青少年早期死亡者的特征和诱发情况,并确定潜在的群体内部种族差异。
我们分析了2003年至2012年美国17个州的国家暴力死亡报告系统(NVDRS)监测数据,这些数据涵盖了自杀死亡情况。参与者包括所有5至14岁的自杀死亡者(N = 693)。根据情况,使用χ检验或Fisher精确检验进行年龄组比较(5至11岁和12至14岁)。
与自杀死亡的青少年早期相比,自杀死亡的儿童更常见为男性、黑人,死于上吊/勒颈/窒息,且在家中死亡。自杀死亡的儿童更常经历与家庭成员/朋友的关系问题(60.3%对46.0%;P = 0.02),而较少经历男朋友/女朋友问题(0%对16.0%;P < 0.001)或留下自杀遗书(7.7%对30.2%;P < 0.001)。在有已知心理健康问题的自杀死亡者中(n = 210),与青少年早期死亡者相比,儿童期死亡者更常患有伴或不伴多动的注意力缺陷障碍(59.3%对29.0%;P = 0.002),而较少患有抑郁症/心境恶劣(33.3%对65.6%;P = 0.001)。
这些发现引发了对于较年轻自杀死亡者对心理社会逆境的冲动反应的疑问,并表明在小学适龄和青少年早期需要通用的和针对发育阶段的自杀预防策略。进一步的研究应调查与黑人儿童自杀率近期上升相关的因素。
