OBJECTIVES
To define different subgroups of suicide attempters according to age at onset of suicide attempts.
METHODS
Participants were 229 suicide attempters (147 females; 82 males) admitted to a general hospital in Madrid, Spain. We used admixture analysis to determine the best-fitting model for the age at onset of suicide attempts separated by sex.
RESULTS
The best fitted model for the age at onset of suicide attempts was a mixture of two gaussian distributions. Females showed an earlier age at onset of suicide attempts in both Gaussian distributions (mean ± S.D.) (26.98 ± 5.69 and 47.98 ± 14.13) than males (32.77 ± 8.11 and 61.31 ± 14.61). Early-onset female attempters were more likely to show borderline personality disorder than late-onset female attempters (OR = 11.11; 95% CI = 2.43-50.0).
CONCLUSIONS
Age at onset of suicide attempts characterizes different subpopulations of suicide attempters.
目的
根据自杀未遂开始的年龄定义不同的自杀未遂亚组。
方法
参与者为西班牙马德里一家综合医院收治的229名自杀未遂者（147名女性；82名男性）。我们使用混合分析来确定按性别划分的自杀未遂开始年龄的最佳拟合模型。
结果
自杀未遂开始年龄的最佳拟合模型是两个高斯分布的混合。在两个高斯分布中，女性自杀未遂开始的年龄（均值±标准差）（26.98±5.69和47.98±14.13）均早于男性（32.77±8.11和61.31±14.61）。早发性女性未遂者比晚发性女性未遂者更易出现边缘性人格障碍（OR = 11.11；95%CI = 2.43 - 50.0）。
结论
自杀未遂开始的年龄可表征不同的自杀未遂亚人群。
