The aim was to compare the rates of suicide in family members of suicide victims and comparison subjects who died of other causes.
The Swedish cause of death register identified all suicides in subjects born between 1949 and 1969 (N=8,396). The comparison group comprised persons of the same age who died of other causes (N=7,568). First-degree relatives of the suicide victims (N=33,173) and comparison subjects (N=28,945) were identified.
Among families of the suicide victims there were 287 suicides, representing 9.4% of all deaths in family members. Among comparison families there were 120 suicides, 4.6% of all deaths. The difference was significant. Previous psychiatric care and suicide in a family member predicted suicide in the logistic regression model.
The rate of suicide was twice as high in families of suicide victims as in comparison families. A family history of suicide predicted suicide independent of severe mental disorder.
比较自杀受害者家庭成员与死于其他原因的对照对象的自杀率。
瑞典死亡原因登记处确定了1949年至1969年出生的所有自杀者（N = 8396）。对照组包括死于其他原因的同龄人群（N = 7568）。确定了自杀受害者的一级亲属（N = 33173）和对照对象（N = 28945）。
在自杀受害者家庭中，有287例自杀，占家庭成员总死亡人数的9.4%。在对照家庭中，有120例自杀，占总死亡人数的4.6%。差异具有统计学意义。在逻辑回归模型中，既往接受过精神科治疗以及家庭成员中有自杀行为可预测自杀。
自杀受害者家庭中的自杀率是对照家庭的两倍。自杀家族史可独立于严重精神障碍预测自杀。
