Studied mostly in developed countries, the increased prevalence of suicide among youth, worldwide, is a preventable public health concern. Guyana, a developing country in South America, has the highest rate of youth death by suicide. Based on the diathesis-stress model, this community-based study aimed to identify both psychiatric and biological factors associated with repeated suicide attempts among high-risk youth.
We measured psychiatric symptoms, childhood traumas, and cortisol to identify correlates with recurrent suicide attempts.
Poisson regression tested the association between psychiatric symptoms, trauma, and cortisol levels on number of suicide attempts among 50 youths from three child welfare orphanages in Guyana. Sixty-six percent were female, and the average age was 14 years. DSM-5 symptom measure was administered and saliva samples collected.
Fifty percent of the youth endorsed suicide attempt. Within this subsample, a minimum of one and maximum of five suicide attempts were self-reported. Participants' number of suicide attempts was positively associated with number of past traumas, psychosis, and depression symptoms.
Suicide prevention screening among at-risk youth should target severity of psychosis and depression reports and number of traumatic life experiences.
我们测量了精神症状、童年创伤和皮质醇水平，以确定与反复自杀企图相关的因素。
泊松回归检验了 50 名来自圭亚那三个儿童福利院的高危青年的精神症状、创伤和皮质醇水平与自杀企图次数之间的关联。66%为女性，平均年龄为 14 岁。进行了 DSM-5 症状测量并采集了唾液样本。
50%的年轻人有自杀企图。在这个亚组中，自我报告的自杀企图次数最少为 1 次，最多为 5 次。参与者的自杀企图次数与过去创伤次数、精神病和抑郁症状呈正相关。
对高危青年进行自杀预防筛查时，应针对精神病和抑郁报告的严重程度以及创伤性生活经历的数量。
