Childhood sexual abuse has been consistently associated with suicidal behavior. We studied suicide attempt features in depressed individuals sexually abused as children. On average, sexual abuse started before age 9. It frequently coexisted with physical abuse. Suicide attempters more often had personality disorders and had endured abuse for longer, but did not differ in terms of other clinical characteristics from non-attempters. Earlier onset of sexual abuse and its duration were associated with more suicide attempts. However, when personality disorders were included in the regression model, only these disorders predicted number of attempts. The severity of sexual abuse and the coexistence of physical abuse were correlated with age at first suicide attempt. However, only severity of sexual abuse was marginally associated with age at first suicide attempt in the regression model. Finally, the earlier the age of onset of sexual abuse, the higher the intent, even after controlling for age, sex and personality disorders. This suggests that the characteristics of childhood sexual abuse, especially age of onset, should be considered when studying the risk for suicidal behavior in abused populations.
儿童期性虐待与自杀行为一直相关。我们研究了遭受儿童期性虐待的抑郁个体的自杀企图特征。平均而言，性虐待开始于 9 岁之前。它经常与身体虐待同时发生。自杀企图者更常患有人格障碍，并且遭受虐待的时间更长，但与非企图者在其他临床特征方面没有差异。性虐待的发病年龄越早和持续时间越长，自杀企图的次数就越多。然而，当将人格障碍纳入回归模型时，只有这些障碍可以预测自杀企图的次数。性虐待的严重程度和身体虐待的共存与首次自杀企图的年龄相关。然而，只有性虐待的严重程度在回归模型中与首次自杀企图的年龄有轻微关联。最后，即使控制年龄、性别和人格障碍，性虐待的发病年龄越早，自杀意图越高。这表明，在研究受虐待人群自杀行为的风险时，应考虑儿童期性虐待的特征，尤其是发病年龄。
